Answer to Question 1

Correct Answer: 1,2,4,5
Rationale: Absorption describes how drugs move from the site of administration to circulating fluids. Distribution describes how drugs are transported throughout the body. Metabolism describes how drugs are converted to a form that is easily removed from the body. Excretion describes how drugs are removed from the body. Pharmacodynamics describes how drugs change body illnesses and pathogens.

Answer to Question 2

Correct Answer: 3
Rationale: Many drugs are excreted in breast milk and can affect the nursing infant. Taking St. John's wort is not likely to cause the baby to have more allergies. Taking St. John's wort is not likely to decrease the amount of milk the mother produces. Taking St. John's wort may affect the taste of the mother's milk, but this is not the most important response.
