Monitoring & clinical assessment

An alarm belongs to a loose electrode

Introductory

The situation

A stable patient is talking while the monitor displays intermittent flat segments. An electrode has lifted during washing. The RN must verify the patient before deciding this is artifact.

What should catch your attention

Patient appears stable
Electrode loose
Trace intermittent

Your immediate priority

Check responsiveness and circulation first, replace the electrode and verify a reliable trace and appropriate alarms.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Check responsiveness and circulation first, replace the electrode and verify a reliable trace and appropriate alarms. [1]
Why it matters Artifact can trigger alarms, but a real deterioration may also be present.
2
Assess actual physiology
Check consciousness, pulse, breathing and symptoms directly; compare observations with the display. [1]
Why it matters Artifact can trigger alarms, but a real deterioration may also be present.
3
Check the measurement
Inspect sensors, connections and the approved setup; obtain an alternative valid measurement when needed. [1]
Why it matters A treatment based on an inaccurate value can harm the patient.
4
Keep monitoring useful
Escalate a confirmed abnormality and document the reliable trend; restore appropriate alarm limits and hand over any fault. [1]
Why it matters Alarms support assessment only when they are audible, correctly configured and acted on.

What to look for next

Compare the corrected rhythm with symptoms and baseline. Recheck after correcting the measurement and after treatment; persistent clinical concern needs review even with a normal display.

Avoid this shortcut

Do not silence the monitor permanently or diagnose arrest from an unverified trace alone. Do not silence repeated alarms without assessing the patient or independently recalibrate an unfamiliar device.

A clear way to hand it over

“I am calling about this new concern: an alarm belongs to a loose electrode. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English Artifact means a misleading signal produced by something other than the patient’s true physiology.

Monitoring & clinical assessment

The telemetry battery runs out during a walk

Introductory

The situation

A patient with recent rhythm problems walks with staff. The remote monitor loses connection and the battery warning is visible. The patient denies symptoms, but monitoring was prescribed for this activity.

What should catch your attention

Monitoring interrupted
Battery warning
Activity underway

Your immediate priority

Pause at a safe location, assess the patient and restore the approved monitoring connection before continuing.

What to look for next

Confirm staff can see the transmitted rhythm and that alarms are functioning. Recheck after correcting the measurement and after treatment; persistent clinical concern needs review even with a normal display.

Avoid this shortcut

Do not assume no alarm means no rhythm problem. Do not silence repeated alarms without assessing the patient or independently recalibrate an unfamiliar device.

A clear way to hand it over

Mobility & fall prevention

An older patient rushes to the bathroom after a diuretic

Introductory

The situation

An older patient has repeated urgency after a prescribed diuretic. They stand quickly, feel dizzy and attempt to carry both a walker and an infusion pump.

What should catch your attention

Urgency
Postural symptoms
Equipment and mobility conflict

Your immediate priority

Offer timely assisted toileting and a safe equipment arrangement; review dizziness and the mobility plan.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Offer timely assisted toileting and a safe equipment arrangement; review dizziness and the mobility plan. [1]
Why it matters A fall can happen while staff are trying to finish an otherwise routine activity.
2
Make movement safe
Stay with the person, help them sit or lie safely and call for assistance. Use the assessed transfer equipment and assistance level. [1]
Why it matters A fall can happen while staff are trying to finish an otherwise routine activity.
3
Assess before restarting
Check symptoms, vital signs, medication timing and mobility compared with baseline. Escalate persistent faintness, injury or new neurological signs. [1]
Why it matters The cause may be illness or a medicine effect; an alarm alone does not address it.
4
Update the plan
Arrange an individualized falls and mobility review, explain how to request help and hand over the new assistance needs. [1]
Why it matters Matching supervision and equipment to the person reduces preventable repeat exposure.

What to look for next

Check symptoms and assisted access on subsequent toilet trips. Recheck symptoms and safe transfer ability before another attempt. New chest pain, breathlessness, bleeding or reduced alertness warrants urgent clinical help.

Avoid this shortcut

Do not simply tell the patient not to move without offering a workable toileting plan. Do not continue an unsafe walk, use a blanket restraint or assume dizziness always means dehydration.

A clear way to hand it over

“I am calling about this new concern: an older patient rushes to the bathroom after a diuretic. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Medication safety

The infusion pump and order use different units

Introductory

The situation

A cardiovascular infusion is prescribed in one unit, but the pump display is configured in another. The patient is stable and the infusion is about to start.

What should catch your attention

Unit mismatch
High-risk infusion
Administration not yet begun

Your immediate priority

Pause and use the approved independent verification of concentration, units, weight if relevant and rate with a qualified colleague.

What the RN should do—and why

1
Respond to the situation first
Pause and use the approved independent verification of concentration, units, weight if relevant and rate with a qualified colleague. [1]
Why it matters A familiar-looking package or copied list cannot establish the right medicine for this person.
2
Pause and verify
Check two approved identifiers, the current order, allergy history, formulation, last dose and the actual medicine supplied. [1]
Why it matters A familiar-looking package or copied list cannot establish the right medicine for this person.
3
Clarify with the team
Contact the prescriber and pharmacist about the discrepancy. Explain urgent omitted-dose risks and obtain a documented safe plan. [1]
Why it matters Both giving the wrong medicine and delaying a time-critical medicine can harm the patient.
4
Close the loop
Record the resolved order, administration decision and monitoring plan; tell the receiving team about any remaining uncertainty. [1]
Why it matters A corrected chart must reach the bedside and the next handover to prevent repetition.

What to look for next

Confirm the verified setup and physiological monitoring before starting. Watch for adverse effects or effects of a delayed dose according to the medicine. Escalate any deterioration rather than wait for routine pharmacy review.

Avoid this shortcut

Do not convert from memory or dismiss different units as a display preference. Do not guess a dose, crush an unsuitable formulation or silently copy conflicting medication lists.

A clear way to hand it over

“I am calling about this new concern: the infusion pump and order use different units. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Communication & discharge

Discharge instructions use an unfamiliar medicine name

Introductory

The situation

A patient says their new 'water tablet' replaces every heart medicine. Several medications changed during admission and the patient cannot explain which were stopped.

What should catch your attention

Changed regimen
Misunderstood replacement
Possible missed essential medicine

Your immediate priority

Reconcile the final list and use teach-back to distinguish each medicine's purpose and the actual stop/start instructions.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Reconcile the final list and use teach-back to distinguish each medicine's purpose and the actual stop/start instructions. [1]
Why it matters Agreement or a smile does not demonstrate understanding of a treatment plan.
2
Make the explanation accessible
Ask the person’s preferred language and communication needs. Use a qualified interpreter for clinical decisions when needed. [1]
Why it matters Agreement or a smile does not demonstrate understanding of a treatment plan.
3
Use a small teach-back
Explain one important step in plain language and ask the person to show or describe it in their own words. [1]
Why it matters This tests how clearly we explained the task without making the person feel examined.
4
Repair the gap
Rephrase, demonstrate and repeat the check. Provide an accessible written plan and a named contact for problems. [1]
Why it matters A usable plan supports safer decisions after the nurse is no longer beside the patient.

What to look for next

Confirm the patient has the verified list, access to medicines and contact instructions. Confirm the person can identify the next step and warning signs. Resolve missing equipment, support or follow-up before an unsafe discharge proceeds.

Avoid this shortcut

Do not add informal instructions that conflict with the prescriber's plan. Do not rely on children to interpret or label a person noncompliant because of a language barrier.

A clear way to hand it over

“I am calling about this new concern: discharge instructions use an unfamiliar medicine name. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

Stay with the patient, obtain urgent assessment and a diagnostic ECG while checking perfusion and preparing the rhythm response. [1]
Why it matters The urgency depends on circulation and symptoms, not the monitor label alone.
2
Check patient and rhythm
Assess responsiveness, pulse, pressure, chest symptoms and breathing; verify the rhythm with reliable monitoring. [1]
Why it matters The urgency depends on circulation and symptoms, not the monitor label alone.
3
Call and prepare
Activate emergency help for instability; begin CPR and AED or defibrillator care when indicated and prepare trained cardioversion or pacing support under protocol. [1]
Why it matters Different rhythms and pulse states require different treatments.
4
Review reversible causes
Assist the team with ECG, electrolytes, medicine review and ordered treatment, with continued monitoring. [1]
Why it matters Correcting the rhythm without addressing causes can lead to recurrence.

What to look for next

Monitor symptoms, pressure and rhythm continuously through treatment. Trend pulse, pressure, consciousness and ECG after treatment. Report recurrence or post-treatment deterioration immediately.

Avoid this shortcut

Do not treat the monitor rate in isolation or leave the patient to walk to another room. Do not give a rhythm drug from a monitor label alone or confuse synchronized cardioversion with an unsynchronized shock.

A clear way to hand it over

“I am calling about this new concern: new palpitations with light-headedness. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Heart failure & fluid balance

Breathlessness increases after a maintenance fluid change

Intermediate

The situation

A patient with heart failure develops rising oxygen needs and crackles after a fluid rate change. Urine has also fallen and pressure is borderline.

What should catch your attention

Congestion cues
Low urine has several causes
Fluid exposure changed

Your immediate priority

Seek prompt review and communicate intake, output, weight and the exact fluid change.

What the RN should do—and why

1
Respond to the situation first
Seek prompt review and communicate intake, output, weight and the exact fluid change. [1]
Why it matters Congestion and impaired circulation can coexist, so one measurement cannot determine treatment.
2
Recognize the pattern
Compare breathlessness, oxygen need, edema, weight, pressure and urine with baseline and assess medication or fluid changes. [1]
Why it matters Congestion and impaired circulation can coexist, so one measurement cannot determine treatment.
3
Escalate the change
Seek urgent clinical review for respiratory distress, hypotension or poor perfusion and prepare the prescribed cardiac investigations. [1]
Why it matters Acute heart failure requires diagnosis and treatment matched to the current physiology.
4
Deliver and review the plan
Give ordered diuretics or respiratory support with the required kidney, electrolyte and output monitoring. [1]
Why it matters Treatment can improve congestion while also changing pressure, kidney function and electrolytes.

What to look for next

Reassess breathing, perfusion and ordered kidney/electrolyte results after the revised plan. Track work of breathing, perfusion, urine and laboratory trends after treatment; report deterioration rather than chasing urine volume alone.

Avoid this shortcut

Do not chase urine output with additional fluid without evaluating congestion. Do not give a routine fluid bolus for low urine or a diuretic for every swollen patient without assessment and authorization.

A clear way to hand it over

“I am calling about this new concern: breathlessness increases after a maintenance fluid change. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

1
Respond to the situation first
Treat using the hypoglycemia pathway appropriate to swallowing safety and ask for an immediate insulin/nutrition plan review. [1]
Why it matters The brain needs glucose; giving food to an unconscious person risks aspiration.
2
Assess and act
Check glucose and consciousness. If the person can swallow safely, give the protocol’s rapid carbohydrate; if not, call urgent help and use the authorized non-oral rescue pathway. [1]
Why it matters The brain needs glucose; giving food to an unconscious person risks aspiration.
3
Check the response
Recheck glucose at the protocol interval, commonly 15 minutes after oral treatment, and repeat or escalate as directed. [1]
Why it matters A single treatment can fail, and symptoms alone do not show that glucose has recovered.
4
Prevent recurrence
Review meal interruption, insulin or other medicines, kidney function and the next nutrition plan with the team. [1]
Why it matters Correction without addressing the cause can lead to another episode soon afterwards.

What to look for next

Confirm glucose recovery and repeat monitoring for recurrence during the interruption. Continue prescribed glucose checks and observe alertness, swallowing and food intake. Some medicines can cause prolonged or recurrent hypoglycemia.

Avoid this shortcut

Do not restart unverified tube feeding solely to correct low glucose. Do not give oral glucose to someone unable to swallow or change insulin orders independently.

A clear way to hand it over

“I am calling about this new concern: the glucose falls when enteral feeding stops. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

What the RN should do—and why

1
Respond to the situation first
Assess urgently, verify the prescribed target and obtain clinical review and blood-gas testing as indicated. [1]
Why it matters Oxygen saturation alone does not show whether carbon dioxide is accumulating.
2
Assess beyond saturation
Check respiratory effort, alertness, fatigue and the prescribed oxygen target; obtain urgent review and ordered blood gases when indicated. [1]
Why it matters Oxygen saturation alone does not show whether carbon dioxide is accumulating.
3
Support targeted treatment
Give controlled oxygen and prescribed bronchodilator treatment; assist indicated non-invasive ventilation with trained staff. [1]
Why it matters Oxygen and ventilatory support address different parts of respiratory failure.
4
Monitor tolerance and response
Check the mask, breathing, consciousness and repeat assessment or blood gases according to the clinical plan. [1]
Why it matters Poor tolerance or worsening physiology can mean that the support strategy needs escalation.

What to look for next

Trend consciousness and ventilation after the corrected support plan. Monitor breathing effort, consciousness, oxygen target and prescribed gas trends, with immediate escalation of worsening ventilation.

Avoid this shortcut

Do not assume the highest saturation is automatically the best target. Do not withhold life-saving oxygen from a critically hypoxic patient or assume more oxygen alone corrects ventilatory failure.

A clear way to hand it over

“I am calling about this new concern: a new oxygen target is not communicated. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

1
Respond to the situation first
Stop the activity, seek urgent cardiac assessment and prepare the prescribed ECG and treatment pathway. [1]
Why it matters Heart ischemia does not always present as a classic crushing chest pain.
2
Recognize the pattern
Assess chest discomfort, breathlessness, sweating, nausea and circulation; call urgent clinical help for concerning or unstable symptoms. [1]
Why it matters Heart ischemia does not always present as a classic crushing chest pain.
3
Prepare time-sensitive assessment
Obtain a prompt ECG and ordered tests, monitoring and access using the local ACS pathway. [1]
Why it matters Early ECG and clinical review guide treatment; one normal tracing does not exclude all ACS.
4
Support ordered treatment
Check allergies, bleeding risk, current medicines and hemodynamics before protocol-directed medicines; prepare transfer if required. [1]
Why it matters Antiplatelet, nitrate and reperfusion decisions depend on diagnosis, contraindications and circulation.

What to look for next

Record symptom onset and response and maintain appropriate rhythm/perfusion monitoring. Reassess pain, breathing, rhythm and perfusion. Report recurrence or evolving ECG changes even after symptoms settle.

Avoid this shortcut

Do not wait for severe pain before reporting a possible recurrent cardiac event. Do not dismiss symptoms as anxiety, give nitrates despite a contraindication or promise a normal ECG rules out a heart attack.

One-sided weakness mistaken for fatigue

Difficult

The situation

A patient receiving anticoagulation for a rhythm disorder becomes unable to lift one arm normally and their speech changes. A colleague suggests they are tired.

What should catch your attention

Focal neurological deficit
New speech change
Anticoagulant exposure relevant

Your immediate priority

Activate the stroke pathway, establish last known well and communicate anticoagulant name and timing.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Activate the stroke pathway, establish last known well and communicate anticoagulant name and timing. [1]
Why it matters Timing and an accurate baseline affect specialist assessment and potential treatment selection.
2
Record time and findings
Note last known well and new face, arm, speech, vision or balance changes; assess airway, breathing and glucose. [1]
Why it matters Timing and an accurate baseline affect specialist assessment and potential treatment selection.
3
Call the stroke pathway
Arrange immediate stroke-team review and urgent imaging; report anticoagulants, recent procedures and seizure history. [1]
Why it matters Imaging is needed to distinguish causes and guide reperfusion or bleeding management.
4
Protect ongoing care
Keep oral intake paused until an approved swallow assessment; follow ordered pressure, oxygen and transfer plans. [1]
Why it matters Aspiration and inappropriate treatment can add harm while the stroke pathway is underway.

What to look for next

Record serial neurological findings and prepare urgent imaging and specialist review. Trend neurological findings and consciousness, document changes with times and ensure the receiving team knows last known well.

Avoid this shortcut

Do not let anticoagulation exclude stroke or independently decide reperfusion eligibility. Do not give food to test swallowing, delay for a complete history or independently lower pressure.

A clear way to hand it over

“I am calling about this new concern: one-sided weakness mistaken for fatigue. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English Last known well is the last time the person was known to be at their usual neurological baseline.

Pleural & ventilation emergency

A pleural drain stops moving during worsening breathlessness

Difficult

The situation

A patient with a chest drain becomes breathless and distressed. The tubing has stopped showing its previous pattern after repositioning and a visible kink is present.

What should catch your attention

Clinical deterioration
Drain function changed
Mechanical obstruction possible

Your immediate priority

Seek urgent assessment, check the external system and correct an obvious kink within the device policy without pulling the drain.

What the RN should do—and why

1
Respond to the situation first
Seek urgent assessment, check the external system and correct an obvious kink within the device policy without pulling the drain. [1]
Why it matters Air trapped around a lung can reduce ventilation and, under tension, impair circulation.
2
Recognize acute change
Assess breathing, chest symptoms, air entry, oxygenation and circulation; activate emergency response for distress or shock. [1]
Why it matters Air trapped around a lung can reduce ventilation and, under tension, impair circulation.
3
Prepare urgent treatment
Support oxygenation and trained ventilation as indicated; prepare the clinician’s emergency decompression or drain equipment. [1]
Why it matters An unstable suspected tension pneumothorax requires immediate clinical management, not routine waiting for imaging.
4
Monitor the drainage plan
After intervention, observe breathing, circulation and the prescribed chest-drain system; report obstruction, disconnection or ongoing instability. [1]
Why it matters Treatment can fail if the drain is not functioning or the underlying leak persists.

What to look for next

Reassess breathing and drain function immediately and escalate failure to improve. Continuously reassess oxygenation, perfusion and drain findings; escalate deterioration immediately.

Avoid this shortcut

Do not routinely clamp a drain treating an air leak or manipulate it beyond competency. Do not clamp an air-leaking drain routinely or attempt needle decompression outside your competence and authorization.

A clear way to hand it over

“I am calling about this new concern: a pleural drain stops moving during worsening breathlessness. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Infection & shock

Persistent delirium hides a new infection

Difficult

The situation

A patient has been intermittently confused since ICU transfer, but now has a new low pressure, tachypnea and reduced urine. The change is being attributed to the existing delirium.

What should catch your attention

New physiological deterioration
Known delirium can distract
Possible infection

Your immediate priority

Activate the acute deterioration/sepsis assessment and communicate how the new findings differ from the earlier baseline.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Activate the acute deterioration/sepsis assessment and communicate how the new findings differ from the earlier baseline. [1]
Why it matters Delay can allow poor organ perfusion to worsen before the diagnosis is fully confirmed.
2
Escalate early
Assess airway, breathing, circulation and mental state; activate the local emergency or sepsis response for shock or rapid decline. [1]
Why it matters Delay can allow poor organ perfusion to worsen before the diagnosis is fully confirmed.
3
Support the prescribed bundle
Prepare cultures and lactate testing, urgent antimicrobials and individualized fluid or vasopressor treatment as ordered; do not delay urgent therapy for a difficult sample. [1]
Why it matters Identifying infection and supporting circulation address different parts of the same emergency.
4
Reassess after each step
Trend blood pressure, breathing, alertness, urine and response to treatment; report overload or persistent poor perfusion. [1]
Why it matters Fluids and medicines must be adjusted to response and comorbidity, rather than repeated automatically.

What to look for next

Track perfusion, respiratory status and response to the prescribed treatment. Continue close observations through transfer and handover. Persistent shock, rising support needs or reduced consciousness requires further immediate escalation.

Avoid this shortcut

Do not use the delirium label to explain every new vital-sign change. Do not wait for fever, laboratory confirmation or a score threshold when clinical shock is evident.

A clear way to hand it over

Vascular access & infusion safety

The infusion site blanches beneath a vasoactive line

Difficult

The situation

A peripheral site delivering a vasoactive medicine becomes pale, painful and swollen. The patient's pressure depends on the infusion and no alternative route is yet ready.

What should catch your attention

Possible extravasation
Tissue-threatening medicine
Essential support depends on access

Your immediate priority

Call urgent help, stop delivery into the affected tissue and do not flush; coordinate verified alternative support and the drug-specific extravasation protocol.

What the RN should do—and why

1
Respond to the situation first
Call urgent help, stop delivery into the affected tissue and do not flush; coordinate verified alternative support and the drug-specific extravasation protocol. [1]
Why it matters A correct pump display does not prove the right drug is connected to the right access.
2
Trace and assess
Trace the line from patient to pump; check site, labels, concentration, rate and the current order. [1]
Why it matters A correct pump display does not prove the right drug is connected to the right access.
3
Escalate the unsafe finding
Stop an unsafe infusion when indicated by the emergency pathway and obtain urgent clinical and pharmacy help; protect time-critical support using the prescribed alternative. [1]
Why it matters Extravasation, disconnection and delivery error can harm tissue or destabilize circulation.
4
Close the safety loop
Arrange safe replacement or investigation, document exposure and verify every connection before restarting under the agreed plan. [1]
Why it matters Correcting one connection must not accidentally interrupt another essential treatment.

What to look for next

Monitor local tissue and systemic pressure throughout the access change. Check the site, perfusion and clinical effect after correction; monitor for delayed tissue injury and report it.

Avoid this shortcut

Do not discard the access before the drug-specific team decides whether it is needed for aspiration or treatment. Do not flush an unknown line, bypass a pump alert or abruptly interrupt lifesaving support without emergency assessment.

Respond to the situation first
Activate urgent hyperkalemia treatment and communicate renal and medicine changes. [1]
Why it matters Severe potassium elevation can cause fatal rhythm changes, sometimes without dramatic symptoms.
2
Assess cardiac risk
Check symptoms, monitoring and ECG promptly; report the potassium result, kidney function and sample concerns without delaying care for an unstable patient. [1]
Why it matters Severe potassium elevation can cause fatal rhythm changes, sometimes without dramatic symptoms.
3
Support ordered stabilization
Prepare protocol-directed calcium when indicated and potassium-shifting or removal treatment; follow independent medicine checks. [1]
Why it matters Calcium protects the heart temporarily but does not remove potassium from the body.
4
Monitor treatment complications
Track repeat potassium and ECG, and glucose checks after insulin-based treatment, following the full monitoring period. [1]
Why it matters Potassium can rebound and treatment can cause delayed hypoglycemia.

What to look for next

Maintain ECG and glucose monitoring and check ordered repeat potassium and definitive removal plans. Escalate ECG deterioration, recurrent high potassium or low glucose. Confirm the plan for potassium removal and medicine review.

Avoid this shortcut

Do not assume a temporary potassium shift has removed potassium from the body. Do not assume a normal ECG excludes danger or that calcium has corrected the potassium level.

Follow the local PE pathway for monitoring, access and ordered imaging or tests; report surgery, immobility and bleeding risk. [1]
Why it matters Clinical assessment determines which tests and treatments are appropriate.
4
Support prescribed treatment
Prepare anticoagulation or emergency specialist treatment as directed, using medicine and bleeding checks. [1]
Why it matters Treating clot risk must be balanced with bleeding and the person’s hemodynamic state.

What to look for next

Monitor breathing and circulation and prepare ordered imaging or rescue interventions. Trend breathing, oxygen needs and circulation; new syncope, hypotension or increasing distress requires further immediate escalation.

Avoid this shortcut

Do not independently start anticoagulation or assume bleeding makes PE impossible. Do not massage a suspected clot, make the breathless patient walk or delay shock care for routine testing.

Respond to the situation first
Call urgent respiratory/critical-care review and prepare escalation of ventilatory support. [1]
Why it matters Oxygen saturation alone does not show whether carbon dioxide is accumulating.
2
Assess beyond saturation
Check respiratory effort, alertness, fatigue and the prescribed oxygen target; obtain urgent review and ordered blood gases when indicated. [1]
Why it matters Oxygen saturation alone does not show whether carbon dioxide is accumulating.
3

Why it matters Oxygen and ventilatory support address different parts of respiratory failure.
4
Monitor tolerance and response
Check the mask, breathing, consciousness and repeat assessment or blood gases according to the clinical plan. [1]
Why it matters Poor tolerance or worsening physiology can mean that the support strategy needs escalation.

What to look for next

Track gas trends and consciousness while maintaining the prescribed support and airway readiness. Monitor breathing effort, consciousness, oxygen target and prescribed gas trends, with immediate escalation of worsening ventilation.

Avoid this shortcut

Do not let equipment troubleshooting delay recognition of NIV failure. Do not withhold life-saving oxygen from a critically hypoxic patient or assume more oxygen alone corrects ventilatory failure.

What the RN should do—and why

1
Respond to the situation first
Activate the tracheostomy emergency pathway and bring airway experts; use the anatomy-specific oxygen/rescue approach. [1]
Why it matters A laryngectomy disconnects the mouth and nose from the lungs, so face-mask oxygen alone cannot work.
2
Identify the airway
Call expert help and check the bedside airway information, breathing and stoma. Distinguish tracheostomy from total laryngectomy. [1]
Why it matters A laryngectomy disconnects the mouth and nose from the lungs, so face-mask oxygen alone cannot work.
3
Follow the trained algorithm
Apply oxygen through the appropriate route and check tube patency using the emergency algorithm within competence; if anatomy is uncertain, follow the algorithm’s face-and-stoma approach. [1]
Why it matters Blocked or displaced tubes require a structured response rather than repeated forced suction or ventilation.
4
Prepare ongoing support
Bring the person’s emergency equipment, assist the airway team and confirm the updated tube and ventilation plan. [1]
Why it matters Tube changes, new stomas and difficult anatomy need specialist decisions and a clear handover.

What to look for next

Verify restored effective ventilation and communicate the event and airway plan. Keep reassessing airflow, chest movement, consciousness and oxygenation throughout the emergency and after tube management.

Avoid this shortcut

Do not blindly force a replacement through a fresh tract. Do not give face-mask-only oxygen to a known laryngectomy or blindly force a displaced tube into a fresh stoma.

Call urgent help again, support ventilation and continue the authorized repeat/rescue and observation pathway. [1]
Why it matters Profound sedation and inadequate breathing can lead to arrest even when supplemental oxygen keeps saturation high.
2
Assess breathing immediately
Check responsiveness and normal breathing, stop further opioid delivery and activate emergency support. Start CPR if indicated by the resuscitation assessment. [1]
Why it matters Profound sedation and inadequate breathing can lead to arrest even when supplemental oxygen keeps saturation high.
3
Ventilate and reverse by protocol
Provide airway positioning and trained ventilation support; give naloxone under the authorized pathway without delaying resuscitation. [1]
Why it matters Naloxone can reverse opioid effects, but oxygen alone does not move enough air into the lungs.
4
Watch for recurrence
Continue monitoring and obtain a safe pain and opioid plan from the treating team. [1]
Why it matters The opioid may act longer than naloxone; improvement can be temporary.

What to look for next

Arrange sufficient monitoring duration and investigate continuing opioid or sedative exposure. Recheck respiratory effort, consciousness, oxygenation and recurrent sedation. Keep observation and escalation active after an initial response.

Avoid this shortcut

Do not assume the first successful reversal ends the risk. Do not leave a drowsy patient alone, rely only on saturation or let naloxone delay CPR.

A clear way to hand it over

“I am calling about this new concern: recurrent respiratory depression after apparent naloxone success. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English Respiratory depression means breathing is too slow or shallow to provide adequate ventilation.

Safe critical-care transfer

The patient deteriorates between units during transfer

Extremely difficult

The situation

A patient with increasing oxygen and rhythm support needs leaves for imaging. During transport, their breathing worsens and portable oxygen supply is near empty.

What should catch your attention

Condition changed
Finite transport supplies
Away from unit rescue resources

Your immediate priority

Stop at a safe location, call the transport/emergency team and provide immediate support; reassess whether the journey can safely continue.

1
Respond to the situation first
Stop at a safe location, call the transport/emergency team and provide immediate support; reassess whether the journey can safely continue. [1]
Why it matters A location change can interrupt lifesaving support and may require a different escort or stabilization first.
2
Check readiness
Review current instability, airway, oxygen or infusion needs and why transfer is needed; involve the responsible clinician. [1]
Why it matters A location change can interrupt lifesaving support and may require a different escort or stabilization first.
3
Prepare equipment and people
Confirm enough oxygen, charged devices, medicines, secure lines, emergency equipment and a trained escort for the person’s support needs. [1]
Why it matters The transport environment has fewer backup resources than the original clinical area.
4
Hand over the real status
Communicate trends, orders, treatment limits, device settings and contingency plans to the accepting team. [1]
Why it matters A destination and referral alone do not provide continuity of critical care.

What to look for next

Confirm adequate supplies, monitoring, trained escort and destination readiness before moving again. Monitor during travel and reassess immediately on arrival; verify all connections, prescribed settings and continuing treatments.

Avoid this shortcut

Do not keep moving solely because the scan is booked. Do not send an unstable supported patient with an unprepared escort or assume devices will keep working because they did on the ward.

A clear way to hand it over

“I am calling about this new concern: the patient deteriorates between units during transfer. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English A contingency plan specifies what to do if the person or equipment deteriorates during transfer.

Monitoring & clinical assessment

Sudden deterioration is missed during an electronic handover

Extremely difficult

The situation

A receiving nurse is reading an electronic transfer summary while the patient develops new chest pain and a low pressure. The written score reflects observations from an hour ago.

What should catch your attention

Current symptoms conflict with old record
No live reassessment
Transfer risk

Your immediate priority

Assess the patient now and activate the urgent response; obtain a direct handover about treatments, trends and unresolved concerns.

1
Respond to the situation first
Assess the patient now and activate the urgent response; obtain a direct handover about treatments, trends and unresolved concerns. [1]
Why it matters Artifact can trigger alarms, but a real deterioration may also be present.
2

Check consciousness, pulse, breathing and symptoms directly; compare observations with the display. [1]
Why it matters Artifact can trigger alarms, but a real deterioration may also be present.
3
Check the measurement
Inspect sensors, connections and the approved setup; obtain an alternative valid measurement when needed. [1]
Why it matters A treatment based on an inaccurate value can harm the patient.
4
Keep monitoring useful
Escalate a confirmed abnormality and document the reliable trend; restore appropriate alarm limits and hand over any fault. [1]
Why it matters Alarms support assessment only when they are audible, correctly configured and acted on.

What to look for next

Replace outdated assumptions with current observations and a clear monitoring plan. Recheck after correcting the measurement and after treatment; persistent clinical concern needs review even with a normal display.

Avoid this shortcut

Do not use a historical early-warning score to override obvious clinical deterioration. Do not silence repeated alarms without assessing the patient or independently recalibrate an unfamiliar device.

A clear way to hand it over

“I am calling about this new concern: sudden deterioration is missed during an electronic handover. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

In plain English Artifact means a misleading signal produced by something other than the patient’s true physiology.
