Answer to Question 1
ANS: D
Maternal perception of fetal movement (quickening) usually begins between 17 and 20 weeks after conception. Because this is her first pregnancy, movement is felt toward the later part of the 17 to 20 weeks. The baby is moving, but you can't feel it yet may be alarming to the woman. Some babies are quiet and you don't feel them move is a true statement; the fetus' movements are not strong enough to be felt until 17 to 20 weeks. However, this statement does not answer the woman's concern. Fetal movement should be felt between 17 and 20 weeks; if movement is not felt by the end of that time, further assessment will be necessary.
Answer to Question 2
ANS: A
During the fetal period, the body systems grow in size and mature in function to allow independent existence after birth. Basic organ systems are developed during the embryonic period. The organs are always at risk for damage from external sources; however, the older the fetus, the more resistant will be the organs. The greatest risk is when the organs are developing. The placental system is complete by week 12, but that is not the best description of the fetal period.
