blood that moves from the right heart into the left hear without coming into contact with
the alveoli. occurs as a result of the emptying of the bronchial and several other veins
into the venous system of the lungs - CORRECT ANSWER: anatomic shunt
diagnose a person with: mucus hyper secretion, wheezes, rhonchi, dyspnea, diminished
breath and heart sounds, barrel chest, progressive hypercapnia, progressive
hypoxemia, cor pulmonlae, accessory muscle use - CORRECT ANSWER: obstructive
respiratory disease

decreased PaO2, SOB, cough, chest pain, fatigue, hx. of weight loss - CORRECT
ANSWER: restrictive pulmonary disease
