A nurse manager witnesses an assistive personnel (AP) using incorrect procedure when transferring a client using a mechanical lift. After reinforcing proper procedure, which of the following methods should the nurse manager use to evaluate the AP's understanding of the teaching?

Rationale: A. This option is incorrect because requiring attendance at an in-service provides additional instruction but does not evaluate whether the assistive personnel understands and can correctly perform the mechanical lift transfer after the teaching has been reinforced. B. This option is incorrect because assigning the assistive personnel to work with a senior staff member offers supervision and support, but it does not assess the AP’s independent understanding or ability to safely use the lift on their own. C. This option is correct because observing the assistive personnel’s technique with the mechanical lift at random times allows the nurse manager to directly evaluate understanding, skill retention, and consistent correct performance in actual practice. Direct observation is the most effective way to assess psychomotor competency. D. This option is incorrect because completing skills modules reinforces knowledge but does not demonstrate the AP’s ability to apply the teaching correctly during real client transfers.
