Fetal Development NCLEX Questions Questions
Question 1 of 5
How many mature ova result from a single cycle of oogenesis?
Correct Answer: A
Rationale: Oogenesis produces one mature ovum per cycle, along with polar bodies that degenerate.
Question 2 of 5
During a pregnant woman’s second trimester anatomy scan, the fetus was in breech position. The patient is now 34 weeks pregnant and asks how she can tell if the baby is in the right position. What test might be ordered to determine this?
Correct Answer: B
Rationale: An ultrasound can determine the fetus's position. Other tests are not typically used for this purpose.
Question 3 of 5
A female carries one positive genetic marker for Huntington’s disease. Her partner does not have any markers for the disease. For which reason is it so important for this family to identify persons with the genetic marker?
Correct Answer: C
Rationale: Symptoms of Huntington's disease manifest later in life, making genetic identification crucial. The other choices either incorrectly describe the genetics of the disease or do not address the significance of identifying carriers.
Question 4 of 5
A patient who is 16 weeks pregnant with her first baby asks how long it will be before she feels the baby move. Which is the nurse’s best answer?
Correct Answer: D
Rationale: 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 perceptible by the end of that time, further assessment will be necessary.
Question 5 of 5
