Verbal orders must be signed by the nurse or pharmacist who took the verbal order and cosigned by the ______________________ who approved them.

In the context of verbal orders in a pharmacy setting, it is essential that these orders are documented and validated to ensure patient safety and proper medication management. The correct answer is the physician, who is the healthcare provider responsible for the patient's overall care and has the authority to prescribe medications.

When a verbal order is given, it typically originates from the physician, and the nurse or pharmacist who receives the order must sign it to acknowledge the receipt and understanding of the instructions. The requirement for co-signature by the physician reinforces accountability and verifies that the order was accurately communicated and understood. This process helps prevent medication errors and ensures that all personnel involved in patient care are operating under the correct directives.

The other options, such as RT (Respiratory Therapist), MSW (Medical Social Worker), and PT (Physical Therapist), do not have the prescribing authority and therefore cannot co-sign a verbal order for medications. This highlights the importance of a physician's role in the medication administration process, ensuring that all orders conform to legal and professional standards.
