What statement should the nurse make to evaluate an older client's ability to measure blood glucose?

To evaluate an older client's ability to measure blood glucose, requesting the client to demonstrate how to use the glucometer and show the results provides a comprehensive assessment of their understanding and skills. This approach allows the nurse to observe the client's technique, confirm their familiarity with the device, and ensure they can interpret the results correctly. By having the client perform the task, the nurse can assess not only their cognitive understanding of the process but also their practical ability to use the device effectively.

This method emphasizes active participation, which can be more beneficial than simply asking what the device is used for or discussing prior issues. Demonstrations by the nurse can serve to clarify needs but do not evaluate the client's independent capability. Similarly, inquiring about past problems with the device does not directly assess the client's current skill level or understanding regarding the blood glucose measurement process.
