Answer to Question 1

1. The cells of the muscle experience hyperplasia with the prolonged need for oxygen..

Rationale:
Hyperplasia is an increase in density or number of normal cells in response to stress, in this case, the increased demand for oxygen. Cells that lose fluid will shrink in size. The cells of a person's heart do not enlarge as a metabolic response. Metaplasia is a change in the normal pattern of differentiation of cells.

Answer to Question 2

3. Post-traumatic stress disorder

Rationale:
Substance abuse is found in many clients with post-traumatic stress disorder as they try to suppress traumatic memories. Obsessive-compulsive disorder, generalized anxiety disorders, and dissociative fugue disorders do not have a high level of traumatic memories.
