What immediate actions should be taken if a patient demonstrates signs of respiratory distress in the PACU?

The correct answer involves providing supplemental oxygen and assessing the airway as immediate actions when a patient exhibits signs of respiratory distress in the Post Anesthesia Care Unit (PACU). This response is crucial because respiratory distress can quickly escalate into a more severe situation if not addressed promptly.

Administering supplemental oxygen helps ensure that the patient receives adequate oxygenation, which is vital for maintaining vital organ function, particularly if their oxygen saturation levels are low. Concurrently, assessing the airway is essential to determine if there are any obstructions or complications affecting the patient's ability to breathe effectively. An open and clear airway is fundamental, especially after anesthesia, which may relax throat muscles, potentially leading to airway compromise.

While encouraging the patient to breathe deeply may seem beneficial, if a patient is in respiratory distress, they may not have the capacity or willingness to take deep breaths due to discomfort or anxiety, making this option less immediate and effective. Calling for a respiratory therapist can be important, but this should follow the initial steps of addressing the patient's immediate needs. Administering sedatives in the context of respiratory distress is contraindicated, as it can further depress the respiratory drive and potentially worsen the patient’s condition.
