CNOR Anesthesia and Sedation Principles 5

Question 1

Which opioid analgesic is most commonly used intraoperatively due to its rapid onset and short duration of action?

Accepted Answer

Fentanyl

Answer

Fentanyl has a rapid onset (1–2 minutes) and relatively short duration, making it ideal for intraoperative titration and analgesia.

Question 2

A patient is receiving epidural patient-controlled analgesia (PCEA) postoperatively. The nurse assesses hypotension and bradycardia. The priority intervention is:

Accepted Answer

Increase IV fluid rate and notify anesthesia provider

Answer

Hypotension and bradycardia from epidural sympathectomy are managed initially with IV fluid bolus and prompt notification of the anesthesia provider for further orders.

Question 3

The purpose of applying cricoid pressure (Sellick's maneuver) during rapid sequence induction (RSI) is to:

Accepted Answer

Occlude the esophagus to prevent passive regurgitation

Answer

Cricoid pressure compresses the esophagus against the vertebral body, reducing the risk of passive regurgitation and aspiration during RSI.

Question 4

Which monitoring modality is REQUIRED by ASA standards during general anesthesia to confirm endotracheal tube placement?

Accepted Answer

Continuous end-tidal CO2 (capnography)

Answer

ASA standards mandate continuous capnography to confirm and monitor endotracheal tube placement throughout general anesthesia.

Question 5

When preparing the OR for a patient with a known latex allergy, the perioperative nurse should:

Accepted Answer

Ensure the room is stocked with latex-free supplies and schedule the case first

Answer

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.
