What should a nurse monitor for following the administration of a neuromuscular blocker in the PACU?

Monitoring for the return of muscle strength and respiratory function after administering a neuromuscular blocker is crucial because these medications temporarily paralyze skeletal muscles, including those involved in respiration. After surgery, it is essential to assess whether the patient is regaining muscle strength to ensure that they can breathe independently and effectively, as well as perform voluntary movements. Since neuromuscular blockers inhibit nerve impulses, their reversal is monitored closely in the PACU to avoid complications such as respiratory distress or the inability to protect the airway.

The return of muscle strength is assessed by checking the patient's ability to move their limbs and maintain adequate muscle tone. Respiratory function is evaluated by monitoring the patient’s ability to take deep breaths, the presence of spontaneous respiratory effort, and ensuring that the airway remains patent. This assessment is a critical responsibility of the nurse in the PACU to ensure patient safety and timely recovery from anesthesia.
