A patient tells the nurse, "I was working out and lifting weights and now that I have stopped, I am flabby and my muscles have gone!" What is the best response by the nurse?
a. "While you are lifting weights, endorphins are released, creating increase in muscle mass, but if the muscles are not used they will atrophy."
b. "The muscle mass has decreased from the lack of calcium in the cells."
c. "Your muscles were in a state of hypertrophy from the weight lifting but it will persist only if the exercise is continued."
d. "Once you stop exercising, the contraction of the muscle does not regain its strength."
