Answer to Question 1

A, C
Immobility decreases the strength of muscles involved in chest wall expansion, which also affects ventilation. The depth of respirations decreases (hypoventilation), and secretions pool in the airways. The ability to effectively cough and expectorate secretions diminishes as muscle tone of the abdomen and chest decrease. As a result, pooled secretions block air passages and alveoli, decrease oxygen and carbon dioxide exchange (hypoxema and hypercarbia), and often lead to atelectasis (collapse of air sacs), or pneumonia. The smooth muscle in the mainstem airway is not reactive as it would be for the patient with asthma, for example.

Answer to Question 2

A, C, D
Proper body mechanics involves good body alignment, erect posture, and a wide base of support. To prevent back injury resulting from reaching and straining muscles, carry objects close to the trunk. Bending at the waist to lift objects uses the back muscles and increases the risk of injury. Instead, squat to lower your center of gravity, and use your leg muscles for lifting.
