What must always be followed when administering PRN medications?

The correct answer emphasizes the importance of adhering to the physician's order regarding the frequency and reason for administering PRN (as needed) medications. This is a fundamental principle in medication management and patient safety.

When a physician prescribes a PRN medication, they provide specific instructions that must be followed to ensure proper care. These orders detail not only when the medication can be given but also the rationale for its use, ensuring that it is only administered for appropriate indications. This approach minimizes the risk of misuse or overmedication and helps maintain therapeutic effectiveness while considering the overall health and safety of the resident.

Additionally, following physician's orders aligns with established protocols and legal responsibilities in healthcare settings. It ensures that the care provided is both safe and effective, adhering to best practices in medication administration.

Other options may suggest relying on personal judgment, preference, or situational circumstances, which can lead to inconsistencies and potential harm to the resident. Prioritizing the physician's guidance ensures that care is standardized and based on medical necessity rather than subjective assessment.
