Answer to Question 1

ANS: B
Antiemetics can mask the underlying cause of vomiting and should not be used until the cause is determined unless vomiting is so severe that dehydration and electrolyte imbalance occurs. Nonpharmacologic measures, such as fluid and electrolyte replacement, should be used. Antibiotics are only used if an infectious cause is determined.

Answer to Question 2

ANS: A
Flushing of the skin and dizziness are common side effects of nicotinic acid, but with careful drug titration and concomitant use of aspirin, these effects can be minimized. Increasing fluid intake or taking with food does not alter these adverse effects. Nicotinic acid can affect liver enzymes not renal function.
