Answer to Question 1

A
Feedback:
Radiation during intrauterine life is a documented cause of leukemia. Radiation of the thyroid in infancy is known to cause thyroid cancer later in life. Asking a female patient about pregnancy status is not something that a nurse is expected to perform. Asking a female patient about being pregnant is not done to determine how much radiation the body can stand or determine how long the patient can be in the radiation room.

Answer to Question 2

A
Feedback:
Although a drug's mechanism of action is the same in any individual, the physiologic immaturity of some body systems in a child can affect a drug's pharmacodynamics (behavior of the medication at the cellular level). The child's age, weight, body surface area, and body composition also can affect the drug's pharmacokinetics (movement of drugs throughout the body via absorption, distribution, metabolism, and excretion).
