a. Lung collapse
b. Hypervolemia
c. Chronic bronchitis
d. Cardiogenic pulmonary edema
ANS: B
Chronic obstructive pulmonary disease (COPD) does not, in and of itself, cause an increase in systemic vascular resistance. Cardiogenic pulmonary edema and lung collapse will decrease sys-temic vascular resistance. Hypovolemia will cause an increase in systemic vascular resistance due to stimulation of the baroreceptor reflex.
