A nurse is reinforcing teaching about foot care to a client who has diabetes mellitus. Which of the following information should the nurse include in the teaching?

A: Image A shows the ankle area, which is an example of a hinge joint, not a ball and socket joint. Hinge joints allow movement in one plane, such as flexion and extension, similar to the motion of a door hinge. The ankle allows primarily up-and-down movement but does not rotate in multiple directions like a ball and socket joint would.

B: Image B shows the hip area, which represents a ball and socket joint. In a ball and socket joint, the round head of one bone fits into the cup-like socket of another bone, allowing movement in multiple directions. The hip and the shoulder are classic examples of ball and socket joints, permitting rotation, flexion, extension, abduction, and adduction.

A. "I should limit my intake of leafy green vegetables.": Limiting leafy green vegetables is associated with warfarin therapy because of their vitamin K content. It is not relevant to metoprolol, which primarily affects the cardiovascular system and does not interact significantly with dietary vitamin K.

B. "I may experience loss of taste.": Loss of taste is not a common side effect of metoprolol. Metoprolol is more associated with cardiovascular side effects such as bradycardia, hypotension, and dizziness rather than alterations in taste perception.

C. "I need to be careful when standing up from bed.": This is correct because metoprolol can cause orthostatic hypotension, leading to dizziness or lightheadedness upon standing. Clients are advised to rise slowly from a lying or seated position to reduce the risk of falls and fainting.

D. "I should expect some weight loss.": Metoprolol is more commonly associated with weight gain or no significant weight change rather than weight loss. Clients taking beta-blockers sometimes experience fluid retention or a slowed metabolism, leading to modest weight gain.
