Which analysis of maternal serum is the best predictor of chromosomal abnormalities in the fetus?
- A. Biophysical profile
- B. Multiple-marker screening
- C. Lecithin-to-sphingomyelin ratio
- D. Blood type and crossmatch of maternal and fetal serum
Correct Answer: B
Rationale: Multiple-marker screening analyzes maternal serum for abnormal levels of AFP, hCG, inhibin A, and estriol to detect chromosomal defects.

Which of the following is the most accurate description of fetal station during labor?
- A. The distance from the cervix to the fetal head
- B. The level of the presenting part in relation to the ischial spines
- C. The degree of fetal flexion during contractions
- D. The amount of cervical dilation during labor
Correct Answer: B
Rationale: The correct answer is B: The level of the presenting part in relation to the ischial spines. Fetal station refers to the position of the baby's head in the mother's pelvis during labor. It is measured in centimeters above or below the ischial spines. This measurement helps determine the progress of labor and the descent of the baby through the birth canal. Choices A, C, and D do not accurately describe fetal station and are therefore incorrect. Choice A refers to the cervical length, choice C refers to fetal position, and choice D refers to cervical dilation, which are not related to fetal station.
A nurse is caring for a postpartum person who is at risk for deep vein thrombosis (DVT). What is the most appropriate nursing intervention?
- A. Encourage ambulation
- B. Apply compression stockings
- C. Administer low-molecular-weight heparin
- D. Monitor for signs of edema
Correct Answer: B
Rationale: The correct answer is B: Apply compression stockings. This intervention is appropriate for a postpartum person at risk for DVT as it helps promote circulation and prevent blood clots by applying pressure to the legs. Compression stockings are a safe and non-invasive method to reduce the risk of DVT. Encouraging ambulation (choice A) is important but may not be feasible immediately postpartum. Administering low-molecular-weight heparin (choice C) would require a prescription and may not be the first-line intervention. Monitoring for signs of edema (choice D) is important but does not directly address the prevention of DVT like compression stockings do.
During the first stage of labor, what is the primary goal of nursing care in the early phase?
- A. Administer pain medication.
- B. Monitor fetal heart rate continuously.
- C. Promote relaxation and provide comfort measures.
- D. Prepare for imminent delivery.
Correct Answer: C
Rationale: The correct answer is C because during the early phase of labor, the primary goal of nursing care is to promote relaxation and provide comfort measures to help the mother cope with contractions and manage pain. This helps create a calm and supportive environment, enhancing the progress of labor. Administering pain medication (A) may be necessary later, not necessarily in the early phase. Monitoring fetal heart rate continuously (B) is important but not the primary goal in the early phase. Preparing for imminent delivery (D) is premature in the early phase, as labor can be lengthy.
A nurse is preparing to administer a tetanus toxoid vaccine to a postpartum person. What is the nurse's priority action before administering the vaccine?
- A. verify the person's immunization history
- B. obtain informed consent
- C. check for signs of an allergic reaction
- D. ensure proper positioning for the vaccine
Correct Answer: D
Rationale: The correct answer is D: ensure proper positioning for the vaccine. It is essential to ensure the person is in the correct position before administering the vaccine to ensure accurate and safe administration. Proper positioning helps prevent injury and ensures the vaccine is administered correctly. Verifying the person's immunization history (choice A) is important but not the priority before administering the vaccine. Informed consent (choice B) should be obtained but is not the priority action in this scenario. Checking for signs of an allergic reaction (choice C) is important but should be done after ensuring proper positioning for the vaccine.
A woman in labor is experiencing severe perineal pressure and the urge to push. What should the nurse assess next?
- A. Cervical dilation
- B. Fetal position
- C. Fetal heart rate
- D. Maternal blood pressure
Correct Answer: A
Rationale: The correct answer is A: Cervical dilation. Assessing cervical dilation is crucial as it indicates the progress of labor and readiness for pushing. The nurse needs to determine if the woman is fully dilated to guide the timing of pushing.
B: Fetal position is important but not the immediate priority when the woman is experiencing the urge to push.
C: Fetal heart rate should be continually monitored during labor but is not the next assessment when the woman has the urge to push.
D: Maternal blood pressure is important but not the immediate concern when the woman is ready to push.
