Maternity HESI Practice Questions

1. What information should the nurse include when teaching a client at 41 weeks of gestation about a non-stress test?

Correct answer: B

Rationale: The correct answer is B: 'This test will determine the adequacy of placental perfusion.' The non-stress test is used to assess fetal well-being by monitoring the fetal heart rate in response to its own movements. It helps determine if the fetus is receiving enough oxygen and nutrients through placental perfusion. Choice A is incorrect because confirming fetal lung maturity is typically determined through tests like amniocentesis, not the non-stress test. Choice C is incorrect because detecting fetal infection is not the primary purpose of a non-stress test. Choice D is incorrect because predicting maternal readiness for labor is not the purpose of the non-stress test; it focuses on fetal well-being.

2. What causes Down's syndrome?

Correct answer: C

Rationale: Down's syndrome, also known as trisomy 21, is caused by the presence of an extra chromosome on the 21st pair. Choice A is incorrect as alcohol abuse is not the cause of Down's syndrome. Choice B is incorrect because Down's syndrome is not related to sex-linked chromosomal abnormalities. Choice D is also incorrect as drug abuse by the mother during pregnancy is not the cause of Down's syndrome.

3. A client who is at 24 weeks of gestation is receiving teaching about expected changes during pregnancy. Which of the following information should the nurse include?

Correct answer: C

Rationale: Nasal stuffiness is a common symptom during pregnancy due to increased blood flow and hormonal changes. This symptom is caused by the increased blood volume and hormonal changes that lead to swelling of the nasal passages. Choices A, B, and D are incorrect. Stomach emptying rate does not significantly change during pregnancy; the uterus does not double in size at 24 weeks but rather grows steadily, and nipples typically darken in color due to increased pigmentation.

4. What is the central layer of the embryo from which the bones and muscles develop?

Correct answer: B

Rationale: The correct answer is mesoderm. The mesoderm is the middle layer of the embryo that gives rise to the bones, muscles, and other connective tissues. The neural tube (choice A) develops into the nervous system, not bones and muscles. The ectoderm (choice C) forms the skin and nervous system, not bones and muscles. The umbilical cord (choice D) is a structure that connects the developing fetus to the placenta; it is not a layer of the embryo that gives rise to bones and muscles.

5. A client at 38 weeks of gestation has a prescription for intravaginal misoprostol. Which of the following statements should the nurse make?

Correct answer: A

Rationale: The correct answer is A. Instructing the client to stay in a side-lying position after receiving misoprostol intravaginally is essential. This position helps keep the medication in place, allowing for better absorption. Choice B is incorrect because oxytocin administration is not typically indicated after misoprostol use. Choice C is incorrect as magnesium supplementation is not part of the standard protocol for misoprostol administration. Choice D is incorrect as having a full bladder is not necessary before initiating misoprostol therapy.
