Question 1

A facility log shows occasional brief air change readings dipping to 14 ACH due to HVAC cycling, with most readings at 15–18 ACH. An elective orthopedic case is scheduled in that room. What is the most appropriate action for the perioperative nurse?

Accepted Answer

Monitor and document transient dips; continue elective scheduling

Question 2

An urgent surgical case requires an implant now, but the last sterilizer run containing the implant has a BI pending (incubation not complete). There is no backup implant. Which policy-based decision tree step is most appropriate immediately?

Accepted Answer

Quarantine implant until BI negative; obtain informed consent if used emergently

Question 3

A patient without written advance directive verbally declines blood transfusion immediately before an intraoperative bleed. What is the perioperative nurse's best action to respect patient preferences while ensuring team adherence?

Accepted Answer

Document verbal refusal, notify surgeon/anesthesia, include restriction in timeout

Question 4

A cardiac implant registry shows two entries for the same device—one entered by the scrub tech and a second duplicate uploaded by the vendor rep. How should the perioperative team correct the registry and the medical record while preserving provenance and legal retention?

Accepted Answer

Reconcile entries, preserve originals, document rationale

Question 5

During induction with succinylcholine and sevoflurane the anesthetist notes a sudden rapid rise in end-tidal $$CO_{2}$$, masseter rigidity, tachycardia, and increasing temperature. Which immediate actions should the intraoperative team perform first?

Accepted Answer

Stop triggers, give 100% $$O_{2}$$, hyperventilate and call dantrolene

Question 6

A vendor representative is in the operating room to set up and calibrate a monitoring device that will remain attached to the patient. The representative indicates they will also interpret waveforms during calibration. According to institutional policy and scope-of-practice principles, which action should the circulating nurse take?

Accepted Answer

Allow nonclinical calibration with RN supervision and documentation

Question 7

A 58-year-old opioid-tolerant patient (baseline 120 mg oral morphine equivalents/day) will undergo open colectomy. Preop plan includes regional block options and multimodal analgesia. Which SMART postoperative pain goal and escalation plan most appropriately balances realistic pain control, timeframes, responsible parties, and explicit escalation criteria?

Accepted Answer

Pain ≤4/10 at rest within 48 hours; start multimodal; regional if >6/10 after two rescue doses

Question 8

During a cardiac implant procedure, the scrub tech reports a biological indicator (BI) processed with the implant tray later returned positive after the tray had been opened and used. Which immediate sequence of actions best protects patient safety and preserves evidence for review?

Accepted Answer

Quarantine instruments, notify surgeon and infection prevention
