Which of the following is a necessary action when providing care to an unresponsive patient who is breathing normally?

When providing care to an unresponsive patient who is breathing normally, repositioning and monitoring the patient is crucial. This action involves placing the patient in the recovery position, which helps keep the airway open and allows any fluids to drain from the mouth. It also prevents aspiration, which is particularly important in unresponsive patients who may have decreased protective reflexes.

Monitoring the patient's condition is vital to ensure they continue to breathe normally. If the patient's breathing becomes inadequate or ceases altogether, you would need to be prepared to initiate further interventions, which could include calling for advanced medical assistance or beginning CPR if the situation dictates. However, the immediate focus, in this case, is ensuring that the patient remains in a safe position and is being observed for any changes in their condition.

Other actions such as administering CPR or clearing the airway would not be necessary if the patient is fully breathing and stable. Calling for advanced medical assistance is also essential, but it follows after ensuring that the unresponsive patient is adequately positioned and monitored. Therefore, repositioning and monitoring constitute the necessary actions for providing care in this specific scenario.
