The umbilical cord is being clamped by the obstetrician. Which of the following physiological changes is taking place at this time?
- A. The baby’s blood bypasses its pulmonary system.
- B. The baby’s oxygen level begins to drop.
- C. Bacteria begin to invade the baby’s bowel.
- D. Bilirubin rises in the baby’s bloodstream.
Correct Answer: A
Rationale: Clamping the umbilical cord initiates the transition from fetal to neonatal circulation, allowing blood to bypass the pulmonary system as the lungs take over oxygen exchange.

The nurse is discussing the methods of confirming the pregnancy with a patient at the first prenatal visit. What method is used to confirm cardiac activity of the fetus?
- A. bimanual exam
- B. pelvic ultrasound
- C. serum pregnancy test
- D. urine pregnancy test
Correct Answer: B
Rationale: The correct answer is B: pelvic ultrasound. Pelvic ultrasound is used to confirm the presence of cardiac activity in the fetus by visualizing the fetal heartbeat. This method is the most accurate and reliable way to confirm the viability of the pregnancy. A bimanual exam (choice A) is a physical examination technique that assesses the size and shape of the uterus but does not confirm fetal cardiac activity. Serum pregnancy test (choice C) and urine pregnancy test (choice D) detect the presence of human chorionic gonadotropin (hCG) hormone in the blood or urine, indicating pregnancy, but do not confirm fetal cardiac activity.
A fetus, descending through the birth canal, is going through the cardinal moves of labor. Please place the following moves in chronological order.
- A. External rotation.
- B. Flexion.
- C. Extension.
- D. Internal rotation.
Correct Answer: D
Rationale: The cardinal movements of labor occur in the following order: flexion, internal rotation, extension, external rotation, and expulsion.
A doula is working with a laboring woman who is 6 cm dilated and is contracting every 3 min × 60 sec on an oxytocin drip. Which of the following interventions should the nurse suggest the doula perform?
- A. Regulate the oxytocin drip rate.
- B. Check the vaginal dilation of the client.
- C. Encourage the woman to use breathing techniques.
- D. Monitor the client for uterine hyperstimulation.
Correct Answer: C
Rationale: The doula's role is to provide emotional and physical support, such as encouraging breathing techniques. Regulating medications and monitoring for complications are the nurse's responsibilities.
The nurse receives a phone call from a patient concerned about the results of the laboratory tests obtained at the first prenatal visit 10 days ago. What is the nurse's next action?
- A. ask the patient if they have checked their electronic chart
- B. inform the patient they will need to wait until the next office visit for the results
- C. provide the patient with the results of the tests
- D. verify the identification of the patient
Correct Answer: D
Rationale: The correct answer is D: verify the identification of the patient. This is crucial to ensure patient safety and confidentiality. By verifying the patient's identity, the nurse can confirm they are providing the correct information to the right person, preventing potential errors or breaches of confidentiality. Asking about the electronic chart (A) is unnecessary if the identity is not confirmed. Informing the patient to wait (B) does not address the immediate concern. Providing results (C) without proper identification can lead to miscommunication. Hence, verifying the patient's identification is the first step to address the patient's concerns effectively.
The nurse is teaching a patient at 28 weeks of gestation how to perform fetal movement counts. What statement by the patient indicates the patient understands teaching?
- A. I need to count the baby's movements for 1 hour every day.
- B. I should wait to count the baby's movements after work.
- C. If the baby moves less than 10 times in 2 hours, I need to call the midwife.
- D. Once the baby moves 5 times, I can stop counting the movements.
Correct Answer: C
Rationale: The correct answer is C because it accurately reflects the recommended protocol for fetal movement counts. By counting fetal movements over a 2-hour period and contacting the midwife if fewer than 10 movements are felt, the patient demonstrates understanding of the importance of monitoring fetal well-being. This approach aligns with the standard practice of assessing fetal activity as a crucial indicator of fetal health.
Choice A is incorrect because counting for 1 hour may not provide a comprehensive assessment. Choice B is incorrect as it suggests delaying monitoring, which could be dangerous if there are concerns about fetal movement. Choice D is incorrect as it implies stopping the count prematurely, potentially missing crucial information about the baby's activity level.
