What intervention should be included in the plan of care for a postoperative patient who received large doses of muscle relaxants and reports difficulty breathing?

In the scenario of a postoperative patient who has received large doses of muscle relaxants and is experiencing difficulty breathing, administering drugs for the reversal of paralysis is the most appropriate intervention. Muscle relaxants can lead to respiratory muscle weakness and paralysis, which may compromise the patient's ability to breathe effectively.

Reversal agents, such as neostigmine and sugammadex, can counteract the effects of the muscle relaxants, restoring the function of the diaphragm and other respiratory muscles. This allows the patient to regain the ability to breathe more normally and reduces the risk of respiratory distress or failure.

Other interventions, while they may provide some support, do not address the root cause of the breathing difficulty in this specific context. Encouraging deep breathing exercises might be helpful for promoting lung expansion but would not resolve the underlying issue of muscle paralysis. Increasing the rate of oxygen delivery can assist in ensuring adequate oxygenation but does not rectify the mechanical problem of weakened respiratory muscles. Administering diuretics is unrelated to the immediate respiratory issue and would not assist in reversing the effects of muscle relaxants. Therefore, using reversal agents directly addresses the concern of respiratory compromise due to muscle relaxant-induced paralysis.
