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.
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.
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.
The nurse is discussing genetically linked diseases with a couple planning a pregnancy. The female states, 'I am concerned because there is a history of sickle-cell disease in my family.' Which information from the nurse is correct?
- A. Any offspring will have the disease.
- B. Only male children will have the disease.
- C. The male partner needs genetic testing.
- D. The couple should not become pregnant.
Correct Answer: C
Rationale: The male partner should undergo genetic testing to determine if he is a carrier of the sickle-cell gene. This information guides the couple's reproductive decisions.
What patient statement indicates the need for further education about amniocentesis?
- A. “It can be used to test for neural tube defects.”
- B. “It is performed between 15 and 20 weeks’ gestation.”
- C. “It is performed using a sterile needle to withdraw a sample of amniotic fluid.”
- D. “The sample can be obtained using a transcervical approach.”
Correct Answer: D
Rationale: Amniocentesis is performed transabdominally, not transcervically, to obtain amniotic fluid.
