For what purpose is pancuronium prescribed to a client requiring mechanical ventilation?

1. Increase respiratory effort

2. Suppress respiratory effort

3. Reduce inflammation

4. Promote sedation

The correct answer is: Suppress respiratory effort

Pancuronium is a muscle relaxant used to suppress respiratory effort in clients requiring mechanical ventilation. This medication works by blocking the transmission of nerve impulses to the muscles, thereby preventing involuntary movements. This is necessary in order to ensure proper functioning of the mechanical ventilator and to optimize oxygenation and ventilation in the client. Options A, C, and D are incorrect because they do not align with the purpose of prescribing pancuronium. Increasing respiratory effort would be counterproductive in a client who is already receiving mechanical ventilation. Reducing inflammation and promoting sedation are not functions of pancuronium.
