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?
- A. The Huntington gene is recessive
- B. All of the couple’s offspring will have the disease
- C. Symptoms do not manifest until 30 to 50 years of age
- D. The expression of the disease is varied by individual
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.

What keeps the endometrium from shedding if conception occurs?
- A. The anterior pituitary temporarily stops producing luteinizing hormone (LH) and follicle stimulating hormone (FSH).

Rationale: hCG maintains the corpus luteum which prevents endometrial shedding.
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?
- A. a biophysical profile
- B. an ultrasound
- C. a fetoscopy
- D. a nonstress test
Correct Answer: B
Rationale: An ultrasound can determine the fetus's position. Other tests are not typically used for this purpose.
A woman who is 8 months pregnant asks the nurse, 'Does my baby have any antibodies to fight infection?' The most appropriate response by the nurse is:
- A. Your baby has all the immune globulins necessary: IgG, IgM, and IgA.
- B. Your baby won't receive any antibodies until he/she is born and you breastfeed him.
- C. Your baby does not have any antibodies to fight infection.
- D. Your baby has IgG and IgM.
Correct Answer: D
Rationale: During the third trimester, the fetus has IgG and IgM. Breastfeeding supplies the baby with IgA.
A 35-year-old woman is 34 weeks pregnant and is diagnosed with oligohydramnios. She asks the nurse to explain how this could affect the pregnancy. Which should the nurse explain to the client? Select all that apply.
- A. The baby’s lungs may be underdeveloped.
- B. The umbilical cord may become compressed.
- C. The mother has developed diabetes mellitus.
- D. It is associated with fetal gastrointestinal abnormalities.
Correct Answer: C
Rationale: Oligohydramnios can cause underdeveloped lungs, compressed umbilical cords, fetal limb abnormalities, and is associated with renal issues. Gastrointestinal abnormalities are less likely.
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?
- A. “You should have felt the baby move by now.”
- B. “The baby is moving, but you can’t feel it yet.”
- C. “Some babies are quiet and you don’t feel them mov
- D. “Within the next month you should start to feel fluttering sensations.”
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.
