The nurse is providing education to the patient about isometric exercises. Which statement by the patient indicates a good understanding?
a. "An example of this type of exercise is walking."
b. "An example of this type of exercise is running."
c. "An example of this type of exercise is Kegels."
d. "An example of this type of exercise is weight lifting."
ANS: C
Isometric exercise requires tension and relaxation of muscles without joint movement. An example is tension and relaxation of pelvic floor muscles (i.e., Kegel exercise). Isotonic exercise involves active movement with constant muscle contraction, such as walking, turning in bed, and self-feeding. Aerobic exercise requires oxygen metabolism to produce energy. Patients may engage in rigorous walking or repeated stair climbing to achieve the positive effects of aerobic exercise. Anaerobic exercise builds power and body mass. Without oxygen to produce energy for activity, anaerobic exercise takes place, such as heavy weight lifting.
