Which abbreviation indicates that a medication is to be given as needed?

The abbreviation "PRN" stands for "pro re nata," which is a Latin phrase meaning "as needed" or "as the situation arises." When a medication is prescribed with the PRN notation, it indicates that the medication should be administered only when necessary, rather than at scheduled intervals. This is commonly used for medications that address symptoms that may not require continuous treatment, such as pain relievers or anti-nausea medications.

Understanding this term is crucial for medication aides, as it directs them on when to administer the medication based on the patient's condition rather than a fixed schedule. Recognizing PRN allows for more responsive and individualized care based on patient needs.

The other abbreviations, while important in medical terminology, refer to different contexts: "qhs" indicates a medication is to be taken every night at bedtime, "pc" refers to medications given after meals, and "stat" indicates that a medication should be administered immediately. Understanding these distinctions helps ensure correct medication management in various situations.
