TEST 2023 QUESTIONS
AND CORRECT
ANSWERS
IC = VT + IRV
Vd = VT ((paCO2 - PeCO2) / paCO2))
3548 = VT + 3040 = 508
Vd = 508 ((40-30)/40)
Vd = 127
Part 2: VA = (VT - Vd) x f
VA = (508 - 127)15
VA = 5715
Part 3: VE = VT x f
VE = 508 x 15
VE = 7620
Given a respiratio...

What is the alveolar ventilation? (room air delivered to the respiratory zone per breath) What is minute ventilation? (total volume of air moved in or out of the lungs per minute) True In children with Down Syndrome, the alveoli are increased in size d/t failure of alveolar multiplication. These enlarged alveoli lead to an overall diminished lu ng surface area for gas exchange compared to normal lungs. T or F True T or F Most of the structures in the bronchi and bronchioles are involved in air distribution rather than gas exchange False T or F Air and blood are in direct contact in the alveoli E. Both A and B Which of the following constitutes total lung capacity? A. Residual volume and vital capacity B. Tidal volume, inspiratory volume, expiratory reserve volume, and residual volume C. Residual volume and tidal volume D. Vital capacity and tida l volume E. Both A and B C. 4.5 L IC = VC - ERV = 6 - 1.5 IC = 4.5 The following lung volumes are obtained on spirometer from a 38 -y/o man with asthma: FRC = 3 L VC = 6 L ERV = 1.5 L What is his IC? A. 9 L B. 7.5 L C. 4.5 L D. 3 L E. Cannot be determined
