Explanation

A.The charge nurse can provide support, but they are not responsible for confirming or authorizing medical orders. Telephone orders must be verified directly with the prescriber.

B.The pharmacist can review medication safety, but they cannot confirm or validate the prescriber’s order over the phone. The responsibility for clarification remains between nurse and prescriber.
C. It's the correct answer and follows the standard safety protocol for verbal/telephone orders:

The nurse writes the order exactly as given
Then reads it back to the prescriber verbatim
The prescriber confirms accuracy before the call ends

This is known as read-back verification, and it reduces medication errors significantly.
D.While clarification may sometimes be needed, routinely hanging up and calling back is not standard practice and increases communication delays. The correct step is to confirm during the same call.
