4. A bronchodilator drug is administered to a patient experiencing acute, severe airway constriction and hypercapnia. The drug decreases the abnormally high arterial carbon dioxide levels because: A. Minute ventilation increases B. Alveolar ventilation increases C. Tidal volume increases D. Dead space volume decreases

Step 1
Hypercapnia means elevated carbon dioxide levels in the blood. Airway constriction reduces the amount of air that can reach the alveoli (air sacs in the lungs) where gas exchange occurs. Show more…

When ventilation is not sufficient, which of the following occurs? a. The capillary constricts. b. The capillary dilates. c. The partial pressure of oxygen in the affected alveolus increases. d. The bronchioles dilate.

76. If a person is hypoventilating, then: A) the partial pressure of carbon dioxide is decreasing B) the rate at which carbonic acid is dissociating into hydrogen ions and bicarbonate ions is increasing C) the rate at which carbonic acid is dissociating into hydrogen ions and bicarbonate ions is decreasing D) the pH of cerebrospinal fluid is increasing E) more oxygen will be able to bind to hemoglobin 77. The oxygen-diffusing capacity increases during exercise primarily due to: A) an increase in the solubility coefficient for oxygen B) a decrease in the thickness of the alveolar-capillary membrane as the lungs are stretched C) an increase in the partial pressure of oxygen in alveolar air D) opening of gated oxygen channels in the alveolar-capillary membrane E) an increase in surface area for diffusion as perfusion of pulmonary capillaries increases 79. The output in the inflation (Hering-Breuer) reflex is: A) prolonged inspiration B) increased respiratory depth C) expiration D) increased blood pressure E) bronchodilation 80. The normal adult value for residual volume is: A) 350 ml B) 500 ml C) 1200 ml D) 3600 ml E) 4800 ml
