A nurse is teaching an older adult client who has type 2 diabetes mellitus about how to care for corns and calluses on her toes. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason:
Evaluating the healing of an incision is not necessary because it involves clinical judgment and assessment skills, which are generally beyond the scope of practice for assistive personnel.
Choice B reason:
Changing IV tubing is a task that can often be safely delegated to an assistive personnel (AP) who has been trained and deemed competent to perform this task. It is within the AP's scope of practice and doesn't require clinical judgment or assessment.
Choice C reason:
Performing a simple dressing change involves direct contact with a wound and requires knowledge of aseptic technique and wound care principles. This task is typically performed by licensed nursing personnel.
Choice D reason:
Inserting an NG tube is a complex procedure that requires specialized training and skill. It should be performed by a licensed nurse or another healthcare professional with the appropriate training and competence.

Choice A reason:
Placing the wasted portion of the controlled substance in the sharp container is not correct. Wasted controlled substances should be disposed of according to specific regulations and facility protocols.
Choice B reason:
Asking a second nurse to record her signature when wasting an unused portion of the controlled substance is not a standard practice. The process for wasting controlled substances usually involves following specific documentation procedures, but this does not necessarily require a second nurse's signature.
Choice C reason:
Verifying the count total of the controlled substance after removing the amount needed is the appropriate action. When administering a controlled substance, it is crucial to maintain accurate accountability of the medication. This includes verifying the count total of the controlled substance before and after removing the amount needed for administration. This step helps ensure proper documentation, prevent errors, and maintain appropriate control over controlled substances.
Choice D reason:
Reporting any discrepancy in the count total of the controlled substance after administration is important, but it should be done as a separate step from verifying the count total before administration. Discrepancies should be reported according to facility policy to ensure proper investigation and resolution.
