Before administering "PRN" medication, what is essential to do?

Knowing the reason the medication is being requested is essential before administering "PRN" (as needed) medication because it ensures that the medication is appropriate for the patient's current condition. PRN medications are not given on a routine schedule but rather based on specific symptoms or needs that arise. Understanding the reason for the request allows the medication aide to confirm that the medication is suitable for the patient's symptoms, ensuring it is used correctly and effectively to address their specific needs.

In addition to knowing the reason, it is important to consider the patient's overall context, including their medical history and other medications they may be taking. This step helps avoid potential complications or interactions. While confirming the expiration date, checking the patient's weight, and assessing vital signs like blood pressure can be important in certain circumstances, they are not as directly critical to the rationale for administering PRN medications as knowing the reason for the request.
