Which opioid analgesic is most commonly used intraoperatively due to its rapid onset and short duration of action?
Answer: Fentanyl
Fentanyl has a rapid onset (1–2 minutes) and relatively short duration, making it ideal for intraoperative titration and analgesia.
A patient is receiving epidural patient-controlled analgesia (PCEA) postoperatively. The nurse assesses hypotension and bradycardia. The priority intervention is:
Answer: Increase IV fluid rate and notify anesthesia provider
Hypotension and bradycardia from epidural sympathectomy are managed initially with IV fluid bolus and prompt notification of the anesthesia provider for further orders.
The purpose of applying cricoid pressure (Sellick's maneuver) during rapid sequence induction (RSI) is to:
Answer: Occlude the esophagus to prevent passive regurgitation
Cricoid pressure compresses the esophagus against the vertebral body, reducing the risk of passive regurgitation and aspiration during RSI.
Which monitoring modality is REQUIRED by ASA standards during general anesthesia to confirm endotracheal tube placement?
Answer: Continuous end-tidal CO2 (capnography)
ASA standards mandate continuous capnography to confirm and monitor endotracheal tube placement throughout general anesthesia.
When preparing the OR for a patient with a known latex allergy, the perioperative nurse should:
Answer: Ensure the room is stocked with latex-free supplies and schedule the case first
A latex-free environment must be established using all latex-free supplies, and scheduling the case first reduces aerosolized latex particle exposure in the room.
A patient emerges from general anesthesia with severe shivering. The nurse should recognize that shivering increases:
Answer: Oxygen consumption by up to 400%
Postoperative shivering dramatically increases metabolic rate and oxygen consumption, which can compromise patients with limited cardiopulmonary reserve.
Sugammadex (Bridion) is used intraoperatively to reverse which class of neuromuscular blocking agents?
Answer: Aminosteroid non-depolarizing agents such as rocuronium and vecuronium
Sugammadex is a modified cyclodextrin that selectively encapsulates aminosteroid non-depolarizing agents, rapidly reversing their neuromuscular blockade.
