Answer to Question 1
B
Gross malformations typically are the result of teratogens consumed during the first trimester. Using teratogenic drugs before becoming pregnant is a risk because 50 of pregnancies are un-intended, and a patient could become pregnant while taking the drug. Exposure to teratogens during the second or third trimester usually alters function, not gross anatomy.
Answer to Question 2
C
An early reaction to antipsychotic drugs is acute dystonia. Initial treatment consists of an anti-cholinergic medication, such as diphenhydramine. Administering more antipsychotic medication would increase the symptoms and could be life threatening. Levodopa is not given for extrapy-ramidal symptoms, because it could counteract the beneficial effects of antipsychotic treatment.
