A nurse is caring for four clients who have drainage tubes. Which of the following clients should the nurse recognize as being at risk for hypokalemia?

A. This is the correct method for identifying the client before administering medication.
Asking for the client's full name and date of birth is a standard and effective way to ensure that the right medication is given to the right person.
B. Depending solely on a family member to verify the client's identity is not considered a reliable method. While involving family members can be helpful in certain situations, the primary responsibility lies with the nurse to directly confirm the client's identity.
C. Verifying the client's room number is not a sufficient method of client identification.
Room numbers can change, and it's possible for clients to be moved, so relying on this alone is not considered safe practice.
D. Checking the client's name on the medication administration record (MAR) is an important step in medication administration, but it is not the initial method of identifying the client. It's used to confirm that the right medication is being administered to the right person after the client's identity has been established through direct interaction and confirmation.

Rationale A: Assisting a client to ambulate using a gait belt is a task within the scope of practice for assistive personnel. It involves physical support and monitoring, which do not require the advanced training of a registered nurse. This task ensures the client's safety while promoting mobility.

Rationale B: Reviewing a low-sodium diet is not within the scope of practice for assistive personnel as it requires nutritional knowledge and the ability to teach, which are responsibilities of a registered nurse or a dietitian.

Rationale C: Feeding a client who had a stroke 3 months ago can be delegated to assistive personnel. This task does not require the clinical judgment of a nurse and can be performed following a predefined plan of care.

Rationale D: Bathing a client who had an amputation 2 days ago can be delegated to assistive personnel. They are trained to assist with activities of daily living, including bathing, while ensuring the client's safety and comfort.

Rationale E: Explaining oral hygiene to a client receiving chemotherapy involves patient education and understanding of the specific needs related to the client's condition, which are beyond the role of assistive personnel. This task requires the expertise of a nurse or other healthcare professional.
