Answer to Question 1

ANS: C
Patients taking warfarin (Coumadin) for anticoagulation prolong the prothrombin time (PT)/international normalized ratio (INR) results if they are taking gingko biloba, garlic, or ginseng with the anticoagulant. The drug interaction can precipitate a life-threatening bleed. Increased cholesterol levels are associated with saturated fat dietary intake. A distended jugular vein and peripheral edema are associated with damage to the right side of the heart. Angina is temporary ischemia of the heart muscle.

Answer to Question 2

ANS: C
Increased body temperature (fever) increases the metabolic rate, thereby increasing carbon dioxide production. The increased carbon dioxide level stimulates an increase in the patient's rate and depth of respiration, causing hyperventilation. Anxiety can cause hyperventilation, but this is not the direct cause from a fever. Sleep causes a decreased respiratory drive; hyperventilation speeds up breathing. The cause of the fever in this question is unknown.
