For which patient would an L/S ratio of 2:1 potentially be considered abnormal?
- A. A 38-year-old gravida 2, para 1, who is 38 weeks’ gestation
- B. A 24-year-old gravida 1, para 0, who has diabetes
- C. A 44-year-old gravida 6, para 5, who is at term
- D. An 18-year-old gravida 1, para 0, who is in early labor at term
Correct Answer: B
Rationale: In diabetic pregnancies, an L/S ratio of 2:1 may not reliably indicate lung maturity due to delayed surfactant production.

Why is pregnancy planning important for women of childbearing age?
- A. Much organogenesis occurs before the missed period
- B. Insurance preapproval is required
- C. No more than 3 pregnancies are recommended
- D. Pregnancies less than 2 years apart stress the cardiovascular system
Correct Answer: A
Rationale: Organogenesis occurs early in pregnancy, often before a missed period, making early intervention critical for fetal health.
A pregnant patient is at 25 weeks gestation and is concerned about her risk of preterm labor. Which of the following symptoms should the nurse educate the patient to report immediately?
- A. Mild back pain and cramping
- B. Increased vaginal discharge
- C. Painful, regular contractions
- D. Feeling of pelvic pressure after physical activity
Correct Answer: C
Rationale: The correct answer is C: Painful, regular contractions. At 25 weeks gestation, experiencing painful, regular contractions could indicate preterm labor, which requires immediate medical attention to prevent premature birth. Mild back pain and cramping (choice A) are common in pregnancy and may not necessarily indicate preterm labor. Increased vaginal discharge (choice B) is also common in pregnancy and not typically a sign of preterm labor. Feeling of pelvic pressure after physical activity (choice D) is common due to the growing uterus and ligament stretching, but it is not a definitive sign of preterm labor unless accompanied by other symptoms like contractions.
During an ultrasound, two amnions and two placentas are observed. What will be the most likely result of this pregnancy?
- A. Dizygotic twins
- B. Monozygotic twins
- C. Conjoined twins
- D. High birth-weight twins
Correct Answer: A
Rationale: Dizygotic twins always have two amnions and two chorions (placentas).
A patient in labor is experiencing back labor and complains of severe back pain. Which position is likely to provide the most comfort?
- A. Supine with knees bent
- B. Hands and knees position
- C. Lying flat on the left side
- D. Sitting upright in a chair
Correct Answer: B
Rationale: The correct answer is B: Hands and knees position. This position helps relieve pressure on the lower back by allowing the baby to shift away from the mother's spine, reducing back pain. It also promotes optimal fetal positioning for labor progress.
A: Supine with knees bent may worsen back labor by putting pressure on the spine.
C: Lying flat on the left side does not actively alleviate back pain or assist with fetal positioning.
D: Sitting upright in a chair may not provide the same relief as the hands and knees position since it doesn't encourage the baby to shift position away from the back.
A pregnant patient at 32 weeks gestation reports persistent nausea and vomiting. What is the nurse's priority action?
- A. Instruct the patient to take over-the-counter anti-nausea medication.
- B. Monitor the patient's hydration status and assess for signs of dehydration.
- C. Encourage the patient to eat large meals more frequently to prevent nausea.
- D. Recommend the patient avoid drinking fluids to prevent further vomiting.
Correct Answer: B
Rationale: The correct answer is B: Monitor the patient's hydration status and assess for signs of dehydration. This is the priority action because nausea and vomiting during pregnancy can lead to dehydration, which can have serious consequences for both the mother and the baby. By monitoring the patient's hydration status and assessing for signs of dehydration, the nurse can ensure early intervention if dehydration occurs.
Incorrect choices:
A: Instruct the patient to take over-the-counter anti-nausea medication - This is not the priority as dehydration needs to be addressed first.
C: Encourage the patient to eat large meals more frequently to prevent nausea - This may exacerbate the nausea and vomiting, leading to further dehydration.
D: Recommend the patient avoid drinking fluids to prevent further vomiting - Dehydration can worsen if the patient avoids fluids.
