Which of the following is a potential complication of maternal hypertension during pregnancy?
- A. Preterm labor
- B. Fetal growth restriction
- C. Placental abruption
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D: All of the above. Maternal hypertension during pregnancy can lead to preterm labor due to uteroplacental insufficiency, fetal growth restriction as the placenta may not provide adequate nutrients and oxygen to the fetus, and placental abruption due to increased risk of vascular damage. These complications can have serious consequences for both the mother and the fetus. Choices A, B, and C are all potential complications associated with maternal hypertension, making option D the correct choice.

A nurse is assessing a newborn whose mother had gestational diabetes mellitus. The nurse should monitor for which of the following findings as a manifestation of hypoglycemia?
- A. Abdominal distention
- B. Petechiae
- C. Increased muscle tone
- D. Jitteriness
Correct Answer: D
Rationale: The correct answer is D: Jitteriness. In newborns of mothers with gestational diabetes mellitus, hypoglycemia can occur due to the abrupt cessation of the maternal glucose supply. Jitteriness is a common manifestation of hypoglycemia in newborns. This is because the brain is highly dependent on glucose for energy, and low blood sugar levels can affect neurological function, leading to symptoms like jitteriness. Abdominal distention, petechiae, and increased muscle tone are not typical manifestations of hypoglycemia in newborns with a history of maternal gestational diabetes mellitus.
What is the function of the umbilical cord during pregnancy?
- A. To transport oxygen and nutrients from the mother to the fetus
- B. To remove waste products from the fetus
- C. To regulate fetal temperature
- D. All of the above
Correct Answer: A
Rationale: The correct answer is A. The umbilical cord functions to transport oxygen and nutrients from the mother to the fetus. This is crucial for the fetus's growth and development. B is incorrect because waste products are removed through the placenta, not the umbilical cord. C is incorrect as the umbilical cord does not regulate fetal temperature. Choice D is incorrect as it includes all options, but only A is accurate.
What is the recommended amount of weight gain during pregnancy for a woman with a normal BMI?
- A. 10-15 pounds
- B. 20-30 pounds
- C. 30-40 pounds
- D. 40-50 pounds
Correct Answer: B
Rationale: The correct answer is B (20-30 pounds). This range is recommended for pregnant women with a normal BMI to support the health of both the mother and the baby. Gaining too little weight can lead to complications like low birth weight, while gaining too much weight increases the risk of gestational diabetes and high blood pressure. The other choices are incorrect because they either fall below or exceed the recommended weight gain range, which can pose risks to the pregnancy. It is crucial for the mother to maintain a healthy weight gain to ensure a safe and successful pregnancy.
A nurse is caring for a client who is at 36 weeks of gestation and has methicillin-resistant Staphylococcus aureus. Which of the following types of isolation precautions should the nurse initiate?
- A. Droplet
- B. Contact
- C. Protective environment
- D. Airborne
Correct Answer: B
Rationale: The correct answer is B: Contact precautions. Methicillin-resistant Staphylococcus aureus (MRSA) is primarily spread through direct contact with infected individuals or contaminated surfaces. Therefore, the nurse should initiate contact precautions to prevent the spread of MRSA to others. Droplet precautions (choice A) are used for diseases transmitted via respiratory droplets, such as influenza. Protective environment (choice C) is used for immunocompromised clients to protect them from environmental pathogens. Airborne precautions (choice D) are for diseases transmitted via small droplet nuclei, like tuberculosis. No other choices are applicable for MRSA.
