A client with fat embolism is receiving 100% FiO₂ on a mechanical ventilator and continues to be hypoxic. Which of the following measures can improve his oxygenation?

Add positive end-expiratory pressure (PEEP)
Give beta blockers
Give diuretics
Increase the FiO₂on the ventilator

Explanation

Answer - A - PEEP can be added to open up alveoli and keep them open. There is no reason to give the client beta blockers. He may benefit from diuresis, but in the meantime, PEEP should be added to improve oxygenation. The highest amount of oxygen that can be delivered is 100% FiO_2.
