CAPA Postanesthesia Care 3

Question 1

Which drug is the reversal agent for neuromuscular blockade caused by rocuronium when using sugammadex?

Accepted Answer

Sugammadex encapsulates rocuronium directly

Answer

Sugammadex works by encapsulating and inactivating steroidal neuromuscular blocking agents like rocuronium and vecuronium.

Question 2

A patient develops laryngospasm in Phase I PACU. After applying CPAP with 100% O2, spasm persists. What is the next intervention?

Accepted Answer

Administer succinylcholine 0.1–0.2 mg/kg IV

Answer

A small (laryngospasm-breaking) dose of succinylcholine relaxes the laryngeal muscles when positive pressure fails to break laryngospasm.

Question 3

Which electrolyte abnormality is most associated with prolonged QT interval and increased risk of Torsades de Pointes in the postanesthesia period?

Accepted Answer

Hypomagnesemia

Answer

Hypomagnesemia prolongs the QT interval and is a common, correctable cause of Torsades de Pointes in postoperative patients.

Question 4

A post-thyroidectomy patient develops inspiratory stridor, neck swelling, and dysphagia 2 hours post-op. What is the priority action?

Accepted Answer

Open the neck wound at bedside to relieve hematoma pressure

Answer

Neck hematoma post-thyroidectomy causing airway compromise requires immediate wound opening to decompress before complete airway obstruction occurs.

Question 5

Which clinical indicator is most reliable for assessing adequate reversal of neuromuscular blockade before PACU discharge?

Accepted Answer

Train-of-four ratio ≥ 0.9

Answer

A train-of-four (TOF) ratio of ≥0.9 indicates adequate neuromuscular recovery and significantly reduces the risk of residual paralysis.
