Post-Operative Respiratory Deterioration on a Short-Staffed Night Shift
Mr. Okafor, 68, is 18 hours post open cholecystectomy. He has a history of COPD (FEV1 55% predicted) and obstructive sleep apnea, and he uses CPAP at home but his machine was not brought in. At 02:00 his respiratory rate is 26, SpO2 89% on 2 L nasal cannula, and he is drowsy but arousable. He received hydromorphone 1 mg IV at 23:30 and again at 01:00 for incisional pain. His last incentive spirometry effort was at 21:00. The unit has one RN for 7 patients; a second patient is due for a blood transfusion check at 02:15. The on-call physician is in the OR and the rapid response team covers three floors.
1. Prioritize your immediate actions in the first 10 minutes and justify the sequence.

First, recognize this as probable opioid-induced respiratory depression compounded by untreated OSA and inadequate pulmonary hygiene, not simply COPD. Immediate sequence:
- Airway and breathing first. Sit him upright, stimulate him, and coach slow deep breaths while you apply continuous pulse oximetry and capnography if available. Rising EtCO2 with falling SpO2 supports hypoventilation rather than a COPD exacerbation.
- Escalate oxygen cautiously. Titrate to SpO2 88–92% given COPD, but do not let a normalized saturation mask worsening ventilation.
- Call for help early. Activate rapid response now rather than waiting; the physician is unavailable and the RRT is the realistic resource. Ask the charge nurse to cover the transfusion check.
- Prepare reversal. Have naloxone at bedside and clarify orders; titrate small doses (0.04–0.1 mg IV) to restore adequate respiratory rate without fully reversing analgesia and precipitating pain crisis or agitation.
- Restart pulmonary hygiene with coached incentive spirometry and consider ordering the home CPAP.
Rationale: hypoventilation kills faster than pain, so ventilation is the priority; early escalation compensates for the staffing constraint.
2. The charge nurse offers to send a float RN for 30 minutes. How do you allocate that resource and what do you hand off?
Read the worked answer
Use the float for the time-critical, non-negotiable task that cannot wait: the 02:15 transfusion check, which is a two-nurse safety requirement and cannot be delayed or done alone. Give a structured handoff (SBAR) covering patient identity, blood product, unit number, start time, vitals baseline, and the requirement for two-person verification at the bedside.
Keep the deteriorating patient with me, because reassessment every 5–15 minutes, titration of oxygen and naloxone, and communication with the RRT require continuity and clinical judgment that a float unfamiliar with the patient cannot provide in 30 minutes. I would also ask the float, if time permits, to retrieve the patient's home CPAP settings from family or records.
Rationale: delegate tasks that are protocolized and time-boxed, retain tasks requiring ongoing assessment and titration. Document the delegation and the rationale.
3. After stabilization, what documentation and communication steps protect the patient and you?
Read the worked answer
Document contemporaneously: the 02:00 findings, the temporal link to the 01:00 hydromorphone dose, interventions and their times, response to naloxone, RRT arrival and recommendations, and the physician notification. Record the missed spirometry and absent CPAP as contributing factors factually, without blame language.
Communicate upward: notify the attending and the on-call physician, place a pharmacy or pain-service consult for opioid regimen review, and request orders for continuous monitoring and a CPAP order. File an incident report per policy as a systems-learning tool, separate from the clinical record.
Rationale: accurate timing and objective data support continuity and defensible practice; the incident report addresses the system gap (staffing, missing CPAP) without becoming part of the chart.
