Answer to Question 1

A
Feedback:
Several medications may reduce the effectiveness of oral contraceptives (i.e., increase the likelihood of pregnancy). These include several antibiotics and antiseizure medications. This combination does not increase blood pressure, risk of thromboembolism, or gastric acid secretion.

Answer to Question 2

D
Feedback:
In adults, total body water is approximately 60, whereas in newborns, it is 80. This difference means that water-soluble drugs are diluted easily and readily moved into intercellular tissue. As a result, serum drug concentrations are lower, and increased dosages of water-soluble drugs may be necessary to maintain therapeutic drug levels. Substitutes may not be available, and fluid restriction does not compensate for this physiological difference.
