Answer to Question 1

B
Feedback:
All aspects of pediatric drug therapy must be guided by the child's age, weight, and level of growth and development. Drugs are generally studied using healthy young men and are never studied in infants because they are not old enough to give consent for themselves. Drug dosages are very specific and a big child may weigh more than an adult and require a larger dose. Even when medications are given accurately, adverse effects can occur.

Answer to Question 2

D
Feedback:
Factors that are known to increase blood pressure in some people include high levels of psychological stress, exposure to high-frequency noise, a high-salt diet, lack of rest, and genetic predisposition. Working outdoors in the sun may increase risk for skin cancer but does not contribute to hypertension. Weight lifting is good exercise, especially if he uses low weight and frequent repetition. Being married with two children is not a contributing factor for hypertension.
