Answer to Question 1

Ans:
A

Feedback:

The period between days 15 and 60 is the most susceptible time during development. Vitamin A, not D, poses a particular risk, and only 2 to 3 of anomalies are attributable to drug and environmental factors. It is not necessary to categorically avoid medication but rather to use caution and heed FDA guidelines.

Answer to Question 2

Ans:
A, B, C, D

Feedback:

Several medications have been considered teratogenic. They include thalidomide, antimetabolites, warfarin, anticonvulsants, ethyl alcohol, cocaine, propyulthiouracil, tetracycline, and Accutane.
