A client is in the recovery room after a surgery which required use of several anesthetic agents, including neuromuscular blocking agents. Which sign and/or symptom would lead the nurse to think the client is experiencing recurarization?

A. Return of weakness after assumed recovery: Recurarization occurs when residual effects of neuromuscular blocking agents reappear after initial recovery. Clients may initially appear to have regained muscle strength, but weakness, inability to lift extremities, or difficulty maintaining airway patency can reemerge. This delayed muscle weakness poses a risk for hypoventilation and airway compromise, requiring monitoring and possible intervention. B. Increased body temperature: Hyperthermia is not a typical sign of recurarization. Elevated body temperature is more commonly associated with malignant hyperthermia or systemic infection rather than residual neuromuscular blockade. Temperature changes alone do not indicate reappearance of muscle paralysis. C. Respiratory depression: While recurarization can indirectly lead to hypoventilation, the hallmark sign is returning generalized muscle weakness. Respiratory depression may develop secondary to weakened respiratory muscles, but it is not the initial identifying feature. Careful assessment of extremity and airway muscle strength is more specific. D. Body rigidity: Rigidity involves involuntary muscle contraction and increased tone, often associated with conditions such as malignant hyperthermia or certain neurologic disorders. Recurarization, in contrast, manifests as flaccid weakness rather than increased muscle tone. Observing rigidity would suggest a different complication than residual neuromuscular blockade.
