Answer to Question 1

ANS: D
During the first 2 weeks, the embryo is not susceptible to teratogenesis. There is no need for an ultrasound.

Answer to Question 2

ANS: D
Low-molecular weight drugs are more likely to cross the placental barrier. This characteristic does not contribute to increased GI distress or toxicity because of reduced renal elimination. Drugs with low molecular weight are not more sensitive to metabolism by maternal hormones.
