A nurse and an assistive personnel (AP) are caring for a client who requests a PRN pain medication. After the nurse administers the medication, which of the following tasks should the nurse assign to the AP?

A. Document the client's respiratory rate in 1 hr: Measuring and recording vital signs, including respiratory rate, is within the scope of practice for an assistive personnel (AP). After the nurse administers a PRN pain medication, the AP can safely monitor and document routine parameters, providing the nurse with data to evaluate the client’s response. B. Monitor the client for an allergic reaction for 30 min: Observing for adverse or allergic reactions requires nursing assessment skills, clinical judgment, and the ability to intervene immediately if a severe reaction occurs. This task is outside the AP’s scope of practice. C. Check the client's response to the medication in 1 hr: Evaluating a client’s pain relief or therapeutic response involves subjective assessment and interpretation, which require nursing judgment. This responsibility cannot be delegated to an AP. D. Evaluate the client for therapeutic effects in 30 min: Assessing the effectiveness of medication, such as pain relief or sedation, requires clinical judgment and decision-making to determine if further interventions are needed. This is a nursing responsibility and should not be assigned to an AP.
