Place the five actions in the safest priority sequence. Urgent steps may occur in parallel when additional qualified staff are available. Stay with Mr. T, stop PCA dosing, call for immediate assistance, assess airway and ventilation, support breathing and oxygenation, and prepare protocol-directed naloxone if needed. Document the clinical findings and response, complete the safety report for proxy PCA activation and the potassium route mismatch, and hand off continuing monitoring and follow-up. Notify the responsible clinician and pharmacist, verify the heparin order and pump, obtain the due aPTT correctly, apply the hospital nomogram, and reassess the remaining potassium need and route. Stop the concentrated potassium infusion at the painful peripheral site and have the site and neurovascular status assessed and managed under facility policy. When the client is stable, secure the PCA control for patient-only use, use teach-back with the client and family, and reassess whether the analgesia plan remains appropriate. ## Explanation Safest sequence: 2 → 3 → 5 → 4 → 1 First, stop opioid delivery and support ventilation (choice 2). Next, stop the tissue-risk potassium infusion and assess the site (choice 3); another qualified nurse can do this while respiratory rescue continues. Then engage the clinician and pharmacist and apply verified medication-specific orders (choice 5). After stabilization, restore patient-only PCA control and verify understanding (choice 4). Finally, complete clinical documentation, safety reporting, and handoff (choice 1). Documentation begins contemporaneously, but it does not replace earlier rescue actions. ## In-depth explanation 1 — Protect ventilation Reduced responsiveness with shallow breathing is the immediate threat. Stop further PCA dosing, remain with the client, call for help, support ventilation, and use naloxone based on clinical response and protocol. 2 — Stop continuing tissue exposure The potassium infusion must not continue while the site burns. Stop and assess before deciding whether any remaining dose is still needed or can be delivered safely. 3 — Reconcile medication-specific plans Clinician and pharmacist input ties heparin changes to a valid result and the hospital nomogram and ties potassium replacement to the repeat level, concentration, route, and access. 4 and 5 — Prevent and close the loop Teach-back and secured patient-only access follow stabilization. Factual documentation, safety reports, and explicit handoff preserve learning and continuing surveillance; real team actions can overlap. ## Clinical scenario Scenario (Stage 5 — Take action) The charge nurse coordinates respiratory rescue, infusion cessation, medication review, teaching, and reporting for simultaneous hazards. Clinical judgment target Sequence threats by immediacy while recognizing parallel team response. ## Key concepts - **Threat-based sequencing** — Address impaired ventilation first, stop ongoing tissue exposure next, then reconcile medication orders and complete prevention, documentation, reporting, and handoff steps. - **Contemporaneous documentation** — Record clinically important findings and actions as care permits while ensuring documentation never delays emergency assessment or treatment. - **Closed-loop handoff** — Transfer the current respiratory, IV-site, laboratory, medication, education, and reporting status plus explicit next assessments to the receiving clinician. ## Related questions - [A client is admitted to the emergency department after ingesting an unknown amount of acet…](https://mymerci.kr/pages/nclex_q.php?qn_id=362720&lang=en) - [A client with chronic heart failure is prescribed metoprolol 25 mg orally twice daily.
