Maternity HESI Practice Questions
1. A client is preparing to administer methylergonovine 0.2 mg orally to a client who is 2 hr postpartum and has a boggy uterus. For which of the following assessment findings should the nurse withhold the medication?
- A. Blood pressure 142/92 mm Hg
- B. Urine output 100 mL in 1 hr
- C. Pulse 58/min
- D. Respiratory rate 14/min
Correct answer: A
Rationale: The correct answer is A. Methylergonovine can increase blood pressure, so it should be withheld if the client has hypertension. A blood pressure reading of 142/92 mm Hg indicates hypertension and is a contraindication for administering methylergonovine. Choices B, C, and D are within normal limits and not contraindications for administering this medication. Urine output, pulse rate, and respiratory rate are not factors that determine the appropriateness of administering methylergonovine in this situation.
2. Tim, a 27-year-old man, has unusually narrow shoulders, low muscle mass, and has no facial and body hair. His doctor recently prescribed testosterone replacement therapy to him. Tim is most likely suffering from:
- A. Phenylketonuria (PKU).
- B. Cystic fibrosis.
- C. Klinefelter syndrome.
- D. Huntington’s disease (HD).
Correct answer: C
Rationale: Tim's physical characteristics, such as narrow shoulders, low muscle mass, and lack of facial and body hair, are typical signs of Klinefelter syndrome, a genetic condition where males have an extra X chromosome (XXY). This leads to underdeveloped testes and reduced testosterone production, resulting in features like gynecomastia, sparse facial and body hair, and reduced muscle mass. Testosterone replacement therapy is commonly used to address the hormonal imbalance in individuals with Klinefelter syndrome. Phenylketonuria (PKU) is a metabolic disorder unrelated to the symptoms described in Tim's case. Cystic fibrosis is a genetic respiratory condition that does not present with the physical characteristics mentioned. Huntington’s disease (HD) is a neurodegenerative disorder primarily affecting motor function and cognition, not physical appearance and muscle mass.
3. A newborn who was born post-term is being assessed by a nurse. Which of the following findings should the nurse expect?
- A. A Rh-negative mother who has an Rh-positive infant
- B. A Rh-positive mother who has an Rh-negative infant
- C. A Rh-positive mother who has an Rh-positive infant
- D. A Rh-negative mother who has an Rh-negative infant
Correct answer: A
Rationale: The correct answer is A: 'A Rh-negative mother who has an Rh-positive infant.' In cases where the newborn is born post-term, the mismatched Rh factor between the mother (Rh-negative) and the infant (Rh-positive) can lead to hemolytic disease of the newborn. This condition occurs when maternal antibodies attack fetal red blood cells, causing hemolysis. This can result in jaundice, anemia, and other serious complications for the infant. Choices B, C, and D are incorrect because they do not reflect the mismatched Rh factor scenario that poses a risk for hemolytic disease of the newborn.
4. A nurse is planning to teach a group of clients who are breastfeeding after returning to work. Which of the following instructions should the nurse include in the teaching?
- A. “Thawed breast milk can be refrigerated for up to 24 hours.”
- B. “Breast milk can be stored in a deep freezer for 12 months.”
- C. “Breast milk can be stored at room temperature for up to 4 hours.”
- D. “Thawed breast milk that is unused cannot be refrozen.”
Correct answer: B
Rationale: The correct answer is B: “Breast milk can be stored in a deep freezer for 12 months.” This instruction is important for mothers returning to work to ensure a long-term storage option for breast milk. Choice A is incorrect because thawed breast milk should be used within 24 hours if stored in the refrigerator. Choice C is incorrect as breast milk can be kept at room temperature for only up to 4 hours. Choice D is incorrect as thawed breast milk that is unused should not be refrozen due to safety concerns.
5. What causes sickle-cell anemia?
- A. A chromosomal abnormality.
- B. A single segment found only on the Y chromosome.
- C. A recessive gene.
- D. A decrease in estrogen levels.
Correct answer: C
Rationale: Sickle-cell anemia is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. The correct answer is C. Choice A is incorrect because sickle-cell anemia is not primarily caused by a chromosomal abnormality. Choice B is incorrect as the condition is not linked to a single segment found only on the Y chromosome. Choice D is unrelated as it mentions a decrease in estrogen levels, which is not a cause of sickle-cell anemia.
