Which hormone is responsible for triggering milk ejection during breastfeeding?
- A. Progesterone
- B. Estrogen
- C. Prolactin
- D. Oxytocin
Correct Answer: D
Rationale: The correct answer is D: Oxytocin. Oxytocin is responsible for triggering milk ejection during breastfeeding by causing the contraction of muscles around the milk-producing cells, facilitating the release of milk. Progesterone and estrogen are involved in preparing the body for pregnancy and maintaining the uterine lining, not milk ejection. Prolactin stimulates milk production but not milk ejection directly. Therefore, the correct choice is oxytocin as it specifically triggers the release of milk during breastfeeding.

A nurse is assessing a late preterm newborn. Which of the following manifestations is an indication of hypoglycemia?
- A. Hypertonia
- B. Increased feeding
- C. Hyperthermia
- D. Respiratory distress
Correct Answer: D
Rationale: The correct answer is D: Respiratory distress. Hypoglycemia in a late preterm newborn can lead to respiratory distress due to inadequate energy supply to respiratory muscles. Hypertonia (choice A) is not a typical manifestation of hypoglycemia. Increased feeding (choice B) is a compensatory mechanism to raise blood glucose levels. Hyperthermia (choice C) is not directly related to hypoglycemia. Therefore, the most appropriate choice indicating hypoglycemia in this scenario is respiratory distress.
A nurse is caring for a client who is receiving oxytocin via continuous IV infusion and is experiencing persistent late decelerations in the FHR. After discontinuing the infusion, which of the following actions should the nurse take?
- A. Instruct the client to bear down and push with contractions.
- B. Administer oxygen at 10 L/min via nonrebreather facemask.
- C. Place the client in a supine position.
- D. Initiate an amnioinfusion.
Correct Answer: B
Rationale: The correct answer is B: Administer oxygen at 10 L/min via nonrebreather facemask. Late decelerations in FHR during oxytocin infusion indicate uteroplacental insufficiency. Administering oxygen helps improve oxygenation to the fetus, potentially alleviating the late decelerations. This action addresses the underlying cause and supports fetal oxygenation. In contrast, option A may increase intrauterine pressure, worsening fetal distress. Option C (supine position) can further compromise placental perfusion. Option D (amnioinfusion) is used for variable decelerations, not late decelerations.
A nurse is caring for a client who is at 20 weeks of gestation and has trichomoniasis. Which of the following findings should the nurse expect?
- A. Thick, white vaginal discharge
- B. Urinary frequency
- C. Vulva lesions
- D. Malodorous discharge
Correct Answer: D
Rationale: The correct answer is D: Malodorous discharge. Trichomoniasis is a sexually transmitted infection caused by a parasite, resulting in a foul-smelling, greenish-yellow vaginal discharge. This characteristic discharge is due to the infection and inflammation of the vaginal mucosa. Option A (Thick, white vaginal discharge) is more indicative of a yeast infection, while option B (Urinary frequency) is not specific to trichomoniasis. Option C (Vulva lesions) is not a common symptom of trichomoniasis. Overall, the malodorous discharge is the key finding in diagnosing trichomoniasis at 20 weeks of gestation.
What is the recommended method of screening for hepatitis B during pregnancy?
- A. Hepatitis B surface antigen (HBsAg) test
- B. Hepatitis B core antibody (HBcAb) test
- C. Hepatitis B e antigen (HBeAg) test
- D. All of the above
Correct Answer: A
Rationale: The HBsAg test is the recommended method for screening for hepatitis B during pregnancy.
What is the recommended method of pain relief for a woman who has a vaginal tear or episiotomy after delivery?
- A. Nonsteroidal anti-inflammatory drugs (NSAIDs)
- B. Acetaminophen
- C. Ice packs
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D: All of the above. Nonsteroidal anti-inflammatory drugs (NSAIDs) help reduce inflammation and pain. Acetaminophen is a pain reliever that can be used in conjunction with NSAIDs for added relief. Ice packs can help reduce swelling and numb the area. Using all three methods together can provide a comprehensive approach to pain relief, targeting different aspects of discomfort such as inflammation, pain, and swelling. This combination can effectively manage pain and promote healing in cases of vaginal tear or episiotomy. Other choices are incorrect because using only one method may not address all aspects of pain and discomfort associated with the condition.
