What additional information must be included in a medication progress note for PRN administration?

Including details of how the patient responded to the medication in a progress note for PRN (as needed) administration is crucial as it provides essential information about the effectiveness of the medication. This response helps healthcare providers assess whether the medication is achieving its intended purpose and can guide future medication decisions. For instance, if a patient took a pain reliever PRN and reported significant pain relief, this information is valuable for determining if the dose was adequate or if adjustments to the medication regimen are required.

Furthermore, documenting the response can also inform discussions with the patient about their ongoing treatment and any necessary changes to their care plan. In the context of PRN medications, this response data ensures that the healthcare team is accurately informed about the patient's condition and medication effectiveness over time.

The other options, while relevant to overall patient care, do not specifically address the critical aspect of medication response which is essential for evaluating PRN medication management.
