A client is vomiting. Which of the following actions should the nurse take first?
- A. Provide the client with an emesis basin
- B. Notify housekeeping
- C. Prevent the client from aspirating
- D. Administer an antiemetic to the client
Correct Answer: C
Rationale: The correct action for the nurse to take first is to prevent the client from aspirating. Aspiration is a serious risk when a client is vomiting as it can lead to respiratory complications. The nurse should position the client on their side to prevent aspiration of vomitus into the airway. This immediate action takes priority over providing an emesis basin, notifying housekeeping, or administering an antiemetic, which do not address the urgent need to prevent aspiration.
