The nursing instructor asks the student to describe fetal circulation, specifically the ductus venosus. Which statement by the student indicates an understanding?
- A. It connects the pulmonary artery to the aorta.
- B. It is an opening between the right and left atria.
- C. It connects the umbilical vein to the inferior vena cava.
- D. It connects the umbilical artery to the inferior vena cava.
Correct Answer: C
Rationale: The correct answer is C because the ductus venosus is a fetal vessel that connects the umbilical vein to the inferior vena cava, allowing oxygenated blood from the placenta to bypass the liver and flow directly to the fetal heart. Choice A is incorrect because the ductus arteriosus connects the pulmonary artery to the aorta. Choice B is incorrect as it refers to the foramen ovale, which is an opening between the right and left atria. Choice D is incorrect as it describes the ductus deferens, a part of the male reproductive system.

How can a nurse support a mother who has chosen not to breastfeed?
- A. Provide resources on breastfeeding benefits
- B. Provide formula samples for feeding
- C. Discuss the risks of formula feeding
- D. Support the mother’s feeding choice without judgment
Correct Answer: D
Rationale: The correct answer is D because it promotes non-judgmental support for the mother's decision. As a nurse, it is crucial to respect the mother's autonomy and decision-making. Providing resources on breastfeeding benefits (choice A) may come off as pressuring or judgmental. Offering formula samples (choice B) may not align with the mother's choice. Discussing risks of formula feeding (choice C) may create guilt or shame. Supporting the mother's feeding choice without judgment (choice D) encourages a positive and supportive environment for the mother.
The nurse is assessing a client at 10 weeks' gestation with hyperemesis gravidarum. What is the priority nursing action?
- A. Encourage small, frequent meals.
- B. Monitor for signs of dehydration.
- C. Administer antiemetics as prescribed.
- D. Encourage fluid intake between meals.
Correct Answer: B
Rationale: The correct answer is B: Monitor for signs of dehydration. Dehydration is a serious complication of hyperemesis gravidarum and can lead to electrolyte imbalances and maternal-fetal complications. By monitoring for signs of dehydration, the nurse can intervene promptly to prevent further complications. Encouraging small, frequent meals (choice A) may help manage nausea but does not address the risk of dehydration. Administering antiemetics (choice C) may be necessary, but monitoring for dehydration takes precedence. Encouraging fluid intake between meals (choice D) is important, but assessing for dehydration is more critical in this situation.
The nurse is teaching a client about foods rich in folic acid during pregnancy. Which food should the nurse recommend?
- A. Citrus fruits.
- B. Lean meats.
- C. Dairy products.
- D. Whole grains.
Correct Answer: A
Rationale: The correct answer is A, citrus fruits. Folic acid is important for fetal development and helps prevent birth defects. Citrus fruits like oranges, grapefruits, and lemons are rich sources of folic acid. They provide the necessary nutrients for a healthy pregnancy. Lean meats (B) are good sources of protein but not specifically high in folic acid. Dairy products (C) are important for calcium but do not contain significant amounts of folic acid. Whole grains (D) are beneficial for fiber and nutrients, but they are not the best source of folic acid compared to citrus fruits.
A client in labor with ruptured membranes is diagnosed with chorioamnionitis. What is the priority nursing action?
- A. Administer prescribed antibiotics.
- B. Encourage the client to ambulate.
- C. Increase the oxytocin infusion rate.
- D. Perform a sterile vaginal examination.
Correct Answer: A
Rationale: The correct answer is A: Administer prescribed antibiotics. The priority nursing action in a client with chorioamnionitis is to administer antibiotics promptly to prevent infection spread to the fetus and mother. Antibiotics help treat the infection and reduce complications. Encouraging ambulation (B) may not be safe due to the risk of infection. Increasing oxytocin infusion rate (C) could worsen the infection. Performing a sterile vaginal examination (D) is contraindicated as it can introduce more bacteria. Administering antibiotics is the most urgent and effective intervention in this situation.

- B. Stools will change from green to yellowish brown
- C. Drink four to six glasses of water per day. to golden yellow over the next several days.
- D. Rest until the contractions subside.
Correct Answer: D
Rationale: The correct answer is D: Rest until the contractions subside. During Braxton Hicks contractions, rest can help alleviate the discomfort. It allows the body to relax and reduces the intensity of the contractions. Other options are incorrect because:
A: Reporting stools with milk curds to the infant's healthcare provider is unrelated to Braxton Hicks contractions.
B: Stool color changes are irrelevant to managing Braxton Hicks contractions.
C: Drinking water is important for overall health during pregnancy but does not directly address Braxton Hicks contractions.
