To assess for muscle atrophy in the legs, which action should the nurse take?

A. Pressing over the shins to measure indentation is a technique used to assess for edema, not muscle atrophy. Edema refers to fluid accumulation in the tissues, which can cause an indentation when pressed, whereas muscle atrophy involves a reduction in muscle mass and would not be detected by this method. B. A goniometer is a tool used to measure the range of motion of joints, not muscle size. While it can be useful in assessing joint mobility and flexibility, it does not provide information about muscle mass or atrophy. C. Comparing the appearance of the legs bilaterally is an appropriate method to assess for muscle atrophy. By visually inspecting and palpating both legs, the nurse can identify differences in muscle bulk and size. Muscle atrophy often presents as noticeable asymmetry between the two legs, with one leg appearing smaller or thinner compared to the other. D. Observing the client during heel-toe ambulation can help assess gait and functional mobility, but it is not the most direct method for evaluating muscle atrophy. While gait abnormalities can suggest underlying muscle weakness or atrophy, direct visual and palpation comparison of muscle mass provides a clearer assessment of muscle atrophy.
