A nurse is collecting data from a client who is taking metoprolol. Which of the following findings should the nurse expect?

A. Warm the insulin vial to dissolve any crystals that develop: Insulin should not be warmed as this can alter its efficacy. If crystals are present, the vial should be gently rolled, not heated.
B. Keep unopened insulin vials in the freezer: Insulin should not be kept in the freezer. Unopened vials should be stored in the refrigerator.
C. Store opened insulin vials at room temperature for up to 4 weeks: Opened insulin vials can be stored at room temperature for up to 4 weeks, which helps maintain its stability and usability.
D. Plan to eat a snack 6 hr after insulin administration: The timing of snacks should be aligned with insulin administration based on the type and dosage, not a fixed interval of 6 hours.

A. Elevate the head of the bed 45° before starting the CPM device: This is incorrect as elevating the head of the bed is not a necessary preparation for using the CPM device. The device should be used according to the specific postoperative guidelines.
B. Ensure the frame joint is in a flexed position before placing the leg onto the device: This is incorrect because the frame joint should generally be in an extended position to properly align the leg for movement through the device's range of motion.
C. Ensure the knee joint is positioned over the CPM device frame joint: This is correct because proper alignment of the knee joint with the CPM device's frame joint is crucial to ensure that the device functions correctly and promotes effective range-of-motion exercises.
D. Instruct the client to increase the degree of flexion as tolerated: This is incorrect because the degree of flexion should be adjusted according to the prescribed protocol by the healthcare provider and should not be self-adjusted by the client.
