Answer to Question 1

D
A pulmonary embolism would reduce or block blood flow to a portion of the lungs. The alveoli would be ventilated but not perfused in the affected area, resulting in an increased / ratio. The ventilation in nonperfused alveoli is wasted, so the VD/VT ratio would also increase.

Answer to Question 2

B
Shallow breathing from a sedative overdose would cause a respiratory acidosis. All of the other options would cause a metabolic acidosis.
