In planning a physical activity program for a patient, the nurse must understand that
a. Isotonic exercises cause contraction without changing muscle length.

c. Isometric contraction involves the movement of body parts.
d. Resistive isometric exercises can lead to bone wasting.
B
The best program of physical activity includes a combination of exercises that produce different physiological and psychological benefits. Isotonic exercises cause muscle contractions and changes in muscle length. Isometric exercises involve tightening or tensing of muscles without moving body parts. Resistive isometric exercises help promote muscle strength and provide sufficient stress against bone to promote osteoblastic activity.
