A woman delivers a fetal demise that has lanugo covering the entire body, nails that are present on the fingers and toes, but eyes that are still fused. Prior to the death, the mother stated that she had felt quickening. Based on this information, the nurse knows that the baby is about how many weeks’ gestation?
- A. 15 weeks.
- B. 22 weeks.
- C. 29 weeks.
- D. 36 weeks.
Correct Answer: B
Rationale: Lanugo typically appears around 16-20 weeks and covers the entire body by 22-24 weeks. Nails begin forming at around 18-20 weeks and are fully developed by 22 weeks. Fused eyelids occur up until about 24-26 weeks, after which they open. Quickening (feeling of fetal movement) usually occurs between 18-22 weeks in first-time pregnancies. Therefore, the most likely gestational age is 22 weeks.
The nurse discusses sexual intimacy with a pregnant couple. Which of the following should be included in the teaching plan?
- A. Vaginal intercourse should cease by the beginning of the third trimester.
- B. Breast fondling should be discouraged because of the potential for preterm labor.
- C. The couple may find it necessary to experiment with alternate positions.
- D. Vaginal lubricant should be used sparingly throughout the pregnancy.
Correct Answer: C
Rationale: Experimenting with alternate positions is often necessary due to changing body dynamics during pregnancy. Vaginal intercourse does not need to stop unless medically advised, breast fondling is unlikely to induce labor, and vaginal lubricants can be used as needed.
A biophysical profile is performed on a pregnant patient. The results show a nonreactive stress test (NST), three episodes of fetal breathing movements (FBMs), limited gross movements, opening and closing of the hand indicating the presence of fetal tone, and adequate amniotic fluid index (AFI). What is the correct interpretation of this test result?
- A. A score of 10 would indicate that the results are equivocal.
- B. A score of 8 would indicate normal results.
- C. A score of 6 would indicate that birth should be considered as a possible treatment option.
- D. A score of 9 would indicate reassurance.
Correct Answer: B
Rationale: A biophysical profile score of 8-10 is considered normal, indicating fetal well-being.
A 30-year-old pregnant patient is at 36 weeks gestation and expresses concerns about swelling in her legs. Which of the following assessments is most important for the nurse to make?
- A. Assess the patient's weight gain during the pregnancy.
- B. Examine the legs for any signs of deep vein thrombosis (DVT).
- C. Instruct the patient to elevate her legs and rest.
- D. Evaluate the patient's dietary intake of sodium.
Correct Answer: B
Rationale: The correct answer is B: Examine the legs for any signs of deep vein thrombosis (DVT). At 36 weeks gestation, pregnant women are at higher risk for DVT due to increased blood volume and pressure on the veins from the growing uterus. DVT can be life-threatening if not detected early. Assessing for any signs of DVT such as redness, warmth, swelling, or pain in the legs is crucial for prompt intervention.
Incorrect choices:
A: Assessing weight gain is important but not the priority in this situation where DVT is a concern.
C: Instructing the patient to elevate her legs and rest can help with swelling but does not address the potential serious complication of DVT.
D: Evaluating dietary intake of sodium is not the priority in this situation where DVT is a concern.
The nurse is reviewing the procedure for alpha-fetoprotein (AFP) screening with a patient at 16 weeks’ gestation. What sample will be collected for the initial screening process?
- A. Urine
- B. Blood
- C. Saliva
- D. Amniotic fluid
Correct Answer: B
Rationale: AFP screening is done using a blood sample, which is less invasive than an amniocentesis.
