Document the refusal and inform the prescriber is the appropriate action for the nurse to take if a client refuses a medication and provides a reason for refusal. The nurse should document the refusal and reason in the client’s medical record, and notify the prescriber of the refusal and the reason given by the client. The prescriber may then choose to modify the medication or the administration method, or may provide additional education or counseling to the client regarding the medication. It is important to respect the client’s autonomy and right to refuse medication, and to work collaboratively with the prescriber to ensure that the client’s care needs are met in a safe and effective manner.

A PRN order does not necessarily indicate the minimum time between doses. PRN stands for "pro re nata," which means "as needed." When a medication is ordered PRN, the healthcare provider should also indicate the frequency or the minimum time between doses, for example, "PRN every 4 hours" or "PRN up to 3 times a day." However, the specific frequency or time between doses may vary depending on the patient's condition and response to the medication, so it is important to follow the healthcare provider's instructions and assess the patient's response before administering the medication again.
