From routine safety to critical change

Learn the reasoning. Follow your local clinical pathway. These are fictional teaching cases, not patient-specific treatment instructions. Adult, pregnancy, pediatric and neonatal responses differ. Use the population-specific pathway and verified weight where required. Use current facility protocols, authorized orders and your scope of practice. Students work under supervision. In a real emergency, activate clinical help rather than consult this page.

How to use these cases Read the cues before opening the actions. Name your first priority, then compare your reasoning. The difficulty describes learning complexity; even an introductory case can involve a serious risk.

Surgical verification & teamwork

The consent and theatre list disagree

Introductory

The situation

A patient arrives for removal of a left-sided lesion. The consent names the left side, but the theatre list says right. The patient is awake and also says left. The team is running late and the discrepancy is being called a typing mistake.

What should catch your attention

Conflicting procedure records
Patient can participate
An irreversible step is approaching

Your immediate priority

Keep the patient involved, notify the surgeon and reconcile the actual procedure, site marking and records before induction or incision as appropriate.

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
Keep the patient involved, notify the surgeon and reconcile the actual procedure, site marking and records before induction or incision as appropriate. [1]
Why it matters A discrepancy should be resolved before the next irreversible step.
2
State the concern clearly
Check the person, procedure, site, consent and relevant safety information with the team at the appropriate checklist stage. [1]
Why it matters A discrepancy should be resolved before the next irreversible step.
3
Use a shared verification
Stop progression when safety information does not agree; involve the responsible surgeon and anesthesia team and document the resolution. [1]
Why it matters A single assumption, memory or vendor reassurance cannot replace team verification.
4
Confirm the final handover
Complete the applicable counts, specimen, equipment and recovery checks and communicate unresolved concerns. [1]
Why it matters Safety checks span the operation and transfer, not only the pre-incision pause.

What to look for next

Confirm the corrected information is shared at the checklist, not only edited in one screen. Recheck after a change in procedure or team and before transfer; ensure the decision is visible to the receiving staff.

Avoid this shortcut

Do not infer the intended side from a previous operation or proceed on verbal reassurance alone. Do not bypass the pause because the schedule is late or treat a signed form as resolution of conflicting information.

A clear way to hand it over

“I am calling about this new concern: the consent and theatre list disagree. 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 time-out is a shared pause to verify essential details before proceeding.

Asepsis & infection prevention

A wet sterile package

Introductory

The situation

While opening an instrument pack, the circulating RN finds moisture on the packaging. The instruments look clean and the scrub team needs them immediately. A replacement tray is available elsewhere.

What should catch your attention

Packaging integrity is uncertain
Clean-looking does not mean sterile
Time pressure

Your immediate priority

Remove the questionable pack from use and arrange a verified replacement through the sterile-processing pathway.

Why it matters An unnoticed or concealed break can expose the surgical field to organisms.
3
Correct safely
Replace or reprocess affected items using the approved sterile pathway and report any patient exposure. [1]
Why it matters A hurried wipe or covering does not establish that a contaminated item is sterile.
4
Maintain prevention measures
Check the agreed prophylaxis, skin preparation and environmental steps with the team; document and hand over relevant exposure. [1]
Why it matters Infection prevention requires reliable processes throughout the procedure.

What to look for next

Check related packs and record the defect for sterile-processing review. Confirm the correction and watch for additional breaks; follow local incident and postoperative infection-review processes when exposure occurred.

Avoid this shortcut

Do not dry the wrapper and declare the contents sterile. Do not quietly continue with doubtful sterility or improvise a reprocessing method.

A clear way to hand it over

“I am calling about this new concern: a wet sterile package. 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 __.”

Positioning & nerve safety

The arm strap has become tight

Introductory

The situation

During a prolonged procedure, an arm board is adjusted and the securing strap now presses tightly against the forearm. The hand is partly obscured by drapes. The patient cannot report pain under anesthesia.

What should catch your attention

Position changed
Compression beneath drapes
Patient cannot report symptoms

Your immediate priority

Ask the team to pause the adjustment and check supported alignment, pressure and perfusion without compromising the sterile field or airway.

What the RN should do—and why

1
Respond to the situation first
Ask the team to pause the adjustment and check supported alignment, pressure and perfusion without compromising the sterile field or airway. [1]
Why it matters Pre-existing impairment and prolonged immobility change the risk of tissue or nerve injury.
2
Check risks and baseline
Review mobility, skin, nerve symptoms and procedure requirements before positioning; communicate vulnerabilities. [1]
Why it matters Pre-existing impairment and prolonged immobility change the risk of tissue or nerve injury.
3
Use trained coordinated positioning
Support limbs and pressure points, avoid excessive stretch or compression and secure lines with the surgical or therapy team. [1]
Why it matters A technically achievable position can still impair perfusion or compress a nerve.
4
Recheck after changes
Reassess visible pressure, alignment, perfusion and devices during the procedure and at recovery handover. [1]
Why it matters Injury can develop after the initial position check or be first recognized in recovery.

What to look for next

Document the correction and include any abnormal limb findings in recovery handover. Report new pain, numbness, weakness, skin change or impaired perfusion and arrange clinical assessment.

Avoid this shortcut

Do not assume the initial position check covers all later changes. Do not let an equipment strap press on a nerve or assume numbness is always an expected anesthetic effect.

A clear way to hand it over

“I am calling about this new concern: the arm strap has become tight. 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

An unlabeled syringe reaches the field

Introductory

The situation

A clear syringe is offered to the sterile field. Two different medicines were drawn up earlier and the person who prepared it has left. No readable label is present.

What should catch your attention

Unknown medicine
Two possible preparations
Original preparer absent

Your immediate priority

Do not administer the unknown syringe; replace it with a properly verified and labeled preparation using the approved checking process.

What the RN should do—and why

1
Respond to the situation first
Do not administer the unknown syringe; replace it with a properly verified and labeled preparation using the approved checking process. [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

Check whether other unlabeled preparations are present and clarify any medicine already given. 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 identify a medicine by its colour, syringe size or usual place on the tray. 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: an unlabeled syringe reaches the field. 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 __.”

Surgical verification & teamwork

The specimen label is for another patient

Introductory

The situation

A specimen container is ready to leave theatre. The label carries a different patient's identifier. The surgeon has also requested orientation markers and the RN needs to preserve that information.

What should catch your attention

Wrong identifier
Specimen orientation matters
Transfer about to occur

Your immediate priority

Hold dispatch and reconcile patient identity, specimen description and orientation with the surgical team before correct labeling.

What the RN should do—and why

1
Respond to the situation first
Hold dispatch and reconcile patient identity, specimen description and orientation with the surgical team before correct labeling. [1]
Why it matters A name, label or location can be confused, especially when patients have similar details. Resolving the mismatch before care prevents treatment, feeds, tests or records being attached to the wrong person.
2
State the concern clearly
Check the person, procedure, site, consent and relevant safety information with the team at the appropriate checklist stage. [1]
Why it matters A discrepancy should be resolved before the next irreversible step.
3

Stop progression when safety information does not agree; involve the responsible surgeon and anesthesia team and document the resolution. [1]
Why it matters A single assumption, memory or vendor reassurance cannot replace team verification.
4
Confirm the final handover
Complete the applicable counts, specimen, equipment and recovery checks and communicate unresolved concerns. [1]
Why it matters Safety checks span the operation and transfer, not only the pre-incision pause.

What to look for next

Confirm the laboratory receives the correct specimen details and incident reporting follows local policy. Recheck after a change in procedure or team and before transfer; ensure the decision is visible to the receiving staff.

Avoid this shortcut

Do not send first and ask the laboratory to sort out identity later. Do not bypass the pause because the schedule is late or treat a signed form as resolution of conflicting information.

A clear way to hand it over

Asepsis & infection prevention

The antibiotic timing changed with a delayed incision

Intermediate

The situation

A procedure is delayed after surgical prophylaxis was given. Incision is now much later than expected and the operation may be long. The RN is uncertain whether a further dose is needed.

What should catch your attention

Delay after prophylaxis
Procedure duration changing
Timing affects the prevention plan

Your immediate priority

Tell anesthesia and surgery the exact administration time and delay; verify whether the local procedure-specific prophylaxis plan requires redosing.

1
Respond to the situation first
Correct the device setup promptly and use an approved warming method; inspect the exposed area and report suspected thermal injury. [1]
Why it matters Shivering may signal heat loss, but fever and other illness also need recognition.
2
Measure and assess
Use an appropriate temperature measurement and assess comfort, exposure and other causes of shivering or instability. [1]
Why it matters Shivering may signal heat loss, but fever and other illness also need recognition.
3
Warm safely
Use approved warming equipment and warmed fluids when prescribed, checking skin and device instructions. [1]
Why it matters Controlled warming limits heat loss without causing avoidable burns.
4
Review the response
Continue temperature and physiological observations and report persistent abnormality. [1]
Why it matters Hypothermia can affect recovery, coagulation and comfort; failure to improve needs reassessment.

What to look for next

Track temperature and skin condition while maintaining safe warming. Check temperature trend, shivering, skin safety and hemodynamics; escalating fever or instability needs urgent review.

Avoid this shortcut

Do not increase unregulated heat to compensate for a low temperature. Do not place an unregulated heat source against the skin or attribute all postoperative shaking to cold.

Announce the pattern to anesthesia and activate the emergency pathway; assist oxygenation, prescribed epinephrine treatment and exposure documentation. [1]
Why it matters A rash may be absent; life-threatening allergy is identified by organ compromise.
2
Recognize severe compromise
Stop the suspected trigger when possible; call emergency help for sudden airway, breathing or circulation problems after an exposure. [1]
Why it matters A rash may be absent; life-threatening allergy is identified by organ compromise.
3
Use the emergency protocol
Give intramuscular epinephrine/adrenaline under the authorized pathway, support airway and oxygenation, and position safely without standing the patient. [1]
Why it matters Epinephrine addresses dangerous airway and circulatory effects; antihistamines do not replace it.
4
Prepare continued care
Arrange ordered fluids, repeat treatment and observation; report the exposure, symptoms and treatment times. [1]
Why it matters Symptoms can persist or recur, requiring monitored follow-up rather than immediate reassurance.

What to look for next

Track response, recurrence and the timing of all possible triggers. Continuously review breathing, perfusion and response. Escalate ongoing compromise and arrange allergy documentation and follow-up after stabilization.

Avoid this shortcut

Do not exclude anaphylaxis because drapes hide skin changes or because bleeding is also possible. Do not wait for a rash, use antihistamines as sole emergency treatment or let a hypotensive person walk.

Activate the local bleeding response for instability; assess airway, breathing, pulse, pressure, alertness and visible loss. [1]
Why it matters External loss can underestimate bleeding, and a normal early blood count cannot rule out shock.
3
Prepare safe resuscitation
Maintain or obtain suitable access within competence; prepare ordered fluids, blood tests and blood products using identification and compatibility checks. [1]
Why it matters Resuscitation supports circulation while the team seeks the bleeding source.
4
Track treatment and source control
Report procedure history, anticoagulants and last doses; help arrange urgent specialist review and prescribed monitoring. [1]
Why it matters Replacement alone cannot stop every source of bleeding or resolve medication-related risk.

What to look for next

Track physiological response, product delivery and ordered coagulation or electrolyte results. Trend observations and loss after interventions. Escalate ongoing shock, respiratory change or a suspected transfusion reaction immediately.

Avoid this shortcut

Do not delay escalation until a later hemoglobin result arrives. Do not wait for a laboratory result before responding to shock or independently select reversal drugs.

1
Respond to the situation first
Announce 'fire' clearly, stop the surgical activity and carry out the rehearsed airway/drape fire response with anesthesia and surgery. [1]
Why it matters An ignition source, fuel and oxygen-rich environment can rapidly harm the airway and skin.
2
Alert the whole team
State that a fire is occurring and identify the site so anesthesia and surgery coordinate immediate action. [1]
Why it matters An ignition source, fuel and oxygen-rich environment can rapidly harm the airway and skin.
3
Use the trained response
Follow the operating-room fire protocol for stopping ignition and oxidizer flow, removing burning material and extinguishing safely, coordinated with anesthesia. [1]
Why it matters Airway fires and drape fires require coordinated action rather than an isolated equipment adjustment.
4
Arrange injury review
After control, assess airway and tissue injury, preserve relevant equipment and document the event for clinical and safety follow-up. [1]
Why it matters An extinguished fire can leave inhalation or thermal injury that is not immediately visible.

What to look for next

Arrange airway and tissue assessment after extinguishing and document the equipment and sequence. Maintain oxygenation using the anesthesia team’s safe rescue plan and monitor for delayed airway effects.

Avoid this shortcut

Do not leave anesthesia unaware while making an isolated oxygen adjustment. Do not spray an unsuitable agent at the airway or manage the oxygen supply independently of the anesthesia response.

Respond to the situation first
Do not connect the mismatched unit; notify anesthesia and the transfusion service immediately and obtain the authorized emergency-release product pathway. [1]
Why it matters A name, label or location can be confused, especially when patients have similar details. Resolving the mismatch before care prevents treatment, feeds, tests or records being attached to the wrong person.
2
Stop exposure and call
Stop the transfusion, assess airway, breathing and circulation and obtain urgent clinical help. Keep access using the approved pathway without flushing residual blood into the person. [1]
Why it matters Continuing a harmful transfusion can intensify the reaction.
3
Check identity and notify
Recheck patient and product identifiers, notify the transfusion service and retain the bag and tubing for investigation. [1]
Why it matters Identity errors and several serious reaction types need immediate investigation.
4
Support the diagnostic plan
Collect ordered blood or urine samples and monitor observations while the team provides reaction-specific treatment. [1]
Why it matters Breathlessness, shock, fever and pain can have different causes that need different treatments.

What to look for next

Recheck every replacement product at the bedside and document the discrepancy without delaying correct rescue supplies. Trend symptoms and circulation continuously in an unstable reaction. Document product details, volume, onset and actions precisely.

Avoid this shortcut

Do not bypass patient identification because the hemorrhage is severe. Do not restart a severe reaction or assume every breathless reaction needs the same fluid or diuretic treatment.

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
Alert anesthesia and deliver oxygen to the stoma using appropriate equipment while the emergency airway team follows the laryngectomy algorithm. [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

Confirm effective ventilation through the correct route and make the anatomy explicit in handover. Keep reassessing airflow, chest movement, consciousness and oxygenation throughout the emergency and after tube management.

Avoid this shortcut

Do not assume every neck stoma still connects to the mouth and nose. Do not give face-mask-only oxygen to a known laryngectomy or blindly force a displaced tube into a fresh stoma.

A clear way to hand it over

“I am calling about this new concern: a laryngectomy patient's oxygen route is wrong. 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 stoma is the neck opening; a tracheostomy and a total laryngectomy have different airway anatomy.

Vascular access & infusion safety

A critical infusion stops during table movement

Extremely difficult

The situation

As the table is moved, a vasopressor line disconnects and the patient's pressure falls. Other infusions remain connected, but their routes and concentrations differ.

What should catch your attention

Essential infusion interrupted
Immediate circulatory change
Multiple lines create error risk

Your immediate priority

Announce the interruption and assist rapid restoration of a verified safe infusion route under the anesthesia emergency plan; protect asepsis and prevent accidental bolus delivery.

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
Announce the interruption and assist rapid restoration of a verified safe infusion route under the anesthesia emergency plan; protect asepsis and prevent accidental bolus delivery. [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

Trace the new setup and assess pressure and tissue perfusion after restoration. Check the site, perfusion and clinical effect after correction; monitor for delayed tissue injury and report it.

Avoid this shortcut

Do not reconnect an unidentified line or flush a drug-filled line as a routine correction. Do not flush an unknown line, bypass a pump alert or abruptly interrupt lifesaving support without emergency assessment.

A clear way to hand it over

“I am calling about this new concern: a critical infusion stops during table movement. 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.

Surgical verification & teamwork

A second emergency develops during the hemorrhage response

Extremely difficult

The situation

The team is managing major bleeding when the scrub RN notices a broken instrument tip is missing. The patient remains unstable and closure decisions are changing.

What should catch your attention

Ongoing life-threatening bleeding
Missing instrument fragment
Competing urgent tasks

Your immediate priority

State the fragment concern without distracting the resuscitation lead; assign a separate count/search response and keep the surgeon informed so both risks remain visible.

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
State the fragment concern without distracting the resuscitation lead; assign a separate count/search response and keep the surgeon informed so both risks remain visible. [1]
Why it matters A discrepancy should be resolved before the next irreversible step.
2
State the concern clearly
Check the person, procedure, site, consent and relevant safety information with the team at the appropriate checklist stage. [1]
Why it matters A discrepancy should be resolved before the next irreversible step.
3
Use a shared verification
Stop progression when safety information does not agree; involve the responsible surgeon and anesthesia team and document the resolution. [1]
Why it matters A single assumption, memory or vendor reassurance cannot replace team verification.
4
Confirm the final handover
Complete the applicable counts, specimen, equipment and recovery checks and communicate unresolved concerns. [1]
Why it matters Safety checks span the operation and transfer, not only the pre-incision pause.

What to look for next

Verify the eventual fragment resolution and investigation in the postoperative handover. Recheck after a change in procedure or team and before transfer; ensure the decision is visible to the receiving staff.

Avoid this shortcut

Do not let the count problem disappear from the record because another emergency took priority. Do not bypass the pause because the schedule is late or treat a signed form as resolution of conflicting information.

A clear way to hand it over

“I am calling about this new concern: a second emergency develops during the hemorrhage response. 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 time-out is a shared pause to verify essential details before proceeding.
