Question 1

A post-thyroidectomy patient develops carpopedal spasm, perioral tingling, and a positive Chvostek sign in the PACU. Which electrolyte abnormality is most likely?

Accepted Answer

Hypocalcemia

Answer

Hypocalcemia occurs after thyroidectomy due to inadvertent parathyroid removal and presents with neuromuscular excitability including Chvostek and Trousseau signs.

Question 2

During CPR in the PACU, the team leader asks for the correct compression-to-ventilation ratio for a single rescuer performing adult CPR. The correct ratio is:

Accepted Answer

30:2

Answer

Current AHA guidelines specify a 30:2 compression-to-ventilation ratio for adult single-rescuer CPR before an advanced airway is placed.

Question 3

A 72-year-old patient in the PACU becomes increasingly confused, hypertensive, and complains of a severe headache following elective hip replacement. Which urgent assessment should the nurse perform first?

Accepted Answer

Perform a focused neurological assessment

Answer

Sudden severe headache with hypertension and altered mental status may indicate intracerebral hemorrhage or hypertensive emergency, requiring immediate neurological assessment.

A PACU patient's arterial blood gas shows pH 7.22, PaCO2 58 mmHg, PaO2 68 mmHg, HCO3 24 mEq/L. This pattern is consistent with:

Accepted Answer

Acute respiratory acidosis

Answer

Low pH with elevated PaCO2 and normal bicarbonate indicates acute respiratory acidosis without metabolic compensation.

Question 5

After administering rocuronium-assisted intubation, the anesthesiologist orders sugammadex for reversal. Which patient condition is a contraindication to sugammadex administration?

Accepted Answer

Known hypersensitivity to sugammadex
