Answer to Question 1

A
Children should not be given bismuth subsalicylate (Pepto-Bismol) because it contains aspirin and can cause Reye's syndrome, a life-threatening condition that affects the liver and central nervous system.

Answer to Question 2

A
All of these values are abnormal; however, only the RBC count is seriously out of the normal range. One of the most serious adverse effects of rifampin (a major part of first-line drug therapy for TB) is suppression of RBC production, leading to anemia. This patient's RBC level is only about half of normal.
