How should a nurse handle a medication ordered "as needed" (PRN)?

The approach outlined in the correct answer emphasizes the importance of closely monitoring the patient's symptoms and administering the medication only when necessary, based on established criteria. This aligns with the core principle of "as needed" (PRN) medication, which is designed to provide treatment in response to specific symptoms or conditions rather than following a fixed schedule.

By using established criteria, the nurse ensures that the medication is given only when it is genuinely needed, minimizing the risk of overmedication and potential side effects. It also helps to ensure that the patient's individual needs are met regarding symptom relief. Effective monitoring allows for timely interventions and helps in evaluating the efficacy of the medication.

This method contrasts with administering medication at regular intervals, as this does not take into account the patient's actual need for symptom relief or contribute to personalized care. Giving the medication only once a day might not provide adequate support for symptoms that require more frequent intervention. Consulting with a physician before any administration may delay necessary treatment and is generally not required unless there are specific concerns regarding the patient's condition or additional clinical judgment is needed.
