Which clients should be assigned to the CNA according to best practices?

The choice indicating that a client pending discharge requesting to ambulate should be assigned to the CNA aligns closely with best practices in delegation within a healthcare setting.

Certified Nursing Assistants (CNAs) are trained to assist patients with activities of daily living, which includes ambulation. In this scenario, the client is nearing discharge and likely requires assistance with walking to ensure safe mobility as part of their readiness to leave the healthcare facility. This task is appropriate for a CNA, as it does not require advanced clinical skills or critical assessments, allowing nurses to focus on more complex care responsibilities.

In contrast, the other options involve tasks that require higher levels of clinical training and decision-making. Medication administration necessitates a registered nurse's knowledge to ensure safety and dosage accuracy. Similarly, wound care management often requires assessment skills that are beyond the CNA's scope of practice. Lastly, a physical assessment involves gathering data that informs the plan of care and must be performed by a licensed nurse. Each of these tasks is critical for patient safety and requires a level of expertise that CNAs are not trained to provide.
