Question 1

A patient receiving epidural analgesia develops sudden hypotension and bradycardia. Which intervention should the medical-surgical nurse prioritize?

Accepted Answer

Administer IV fluid bolus and position the patient supine

Answer

Sympathetic blockade from epidural analgesia causes vasodilation and hypotension, so IV fluid bolus and supine positioning restore venous return and blood pressure.

Question 2

Which assessment finding in a post-anesthesia patient most strongly suggests malignant hyperthermia?

Accepted Answer

Rapidly rising end-tidal CO2 and muscle rigidity

Answer

Malignant hyperthermia classically presents with unexplained rise in end-tidal CO2, skeletal muscle rigidity, and rapidly increasing body temperature.

Question 3

A medical-surgical nurse is monitoring a patient who received spinal anesthesia. At what dermatomal level does a spinal block pose the greatest risk for respiratory compromise?

Accepted Answer

T4 and above

Answer

Spinal blocks reaching T4 or higher can impair intercostal muscle function and potentially affect the phrenic nerve, leading to respiratory compromise.

Question 4

Which laboratory value is most critical to monitor in a patient receiving prolonged propofol infusion for procedural sedation?

Accepted Answer

Triglyceride level

Answer

Propofol is formulated in a lipid emulsion, and prolonged infusion can cause hypertriglyceridemia and propofol infusion syndrome.

Question 5

A patient with a history of obstructive sleep apnea is ordered opioid analgesia postoperatively. Which nursing action is most appropriate?

Accepted Answer

Use continuous pulse oximetry and capnography monitoring

Answer

Patients with obstructive sleep apnea are at increased risk for opioid-induced respiratory depression and require continuous monitoring of oxygenation and ventilation.
