A client has experienced significant decreases in mobility and stamina during a 3-week hospital stay for the treatment of a femoral head fracture
Which of the following phenomena most likely accounts for the client's decrease in muscle function?
A) Impaired muscle cell metabolism resulting from metaplasia
B) Dysplasia as a consequence of inflammation during bone remodeling
C) Disuse atrophy of muscle cells during a prolonged period of immobility
D) Ischemic atrophy resulting from vascular changes while on bedrest
Ans: C
Feedback:
Disuse atrophy frequently occurs as a consequence of prolonged periods of muscle inactivity. Metaplasia and dysplasia are not common consequences of immobility and muscle disuse. Similarly, infrequent muscle use does not typically cause vascular changes that result in ischemic atrophy.
