Maternity HESI Practice Questions
1. The nurse places one hand above the symphysis while massaging the fundus of a multiparous client whose uterine tone is boggy 15 minutes after delivering a 7-pound, 10-ounce (3220-gram) infant. Which information should the nurse provide to the client about these findings?
- A. The uterus should be firm to prevent an intrauterine infection.
- B. Both the lower uterine segment and the fundus must be massaged.
- C. A firm uterus prevents the endometrial lining from being sloughed.
- D. Clots may form inside a boggy uterus and need to be expelled.
Correct answer: D
Rationale: After childbirth, a boggy uterus indicates poor uterine tone, which can lead to the formation of clots. Massaging the fundus helps the uterus contract and expel clots, reducing the risk of postpartum hemorrhage. Choices A, B, and C are incorrect because the main concern with a boggy uterus is the risk of clot formation and postpartum hemorrhage, not solely preventing intrauterine infection, massaging the lower uterine segment, or preventing the endometrial lining from sloughing.
2. A prenatal educator is teaching a class about false labor. Which of the following information should the educator include?
- A. Contractions will become more intense with walking
- B. There will be dilation and effacement of the cervix
- C. There will be bloody show
- D. Contractions will become temporarily regular
Correct answer: D
Rationale: The correct answer is D. False labor contractions, also known as Braxton Hicks contractions, are typically irregular and do not lead to cervical dilation or effacement. They are often described as sporadic and temporary, becoming temporarily regular. Choices A, B, and C are incorrect because false labor contractions do not intensify with activity, do not cause cervical changes like dilation and effacement, and are not associated with the presence of a bloody show.
3. Polygenic traits are those that are:
- A. developed during adolescence.
- B. transmitted by the mother.
- C. uncommon in humans.
- D. determined by several pairs of genes.
Correct answer: D
Rationale: Polygenic traits, such as height and skin color, are determined by several pairs of genes working together. These traits are influenced by the combined effects of multiple genes across the genome, rather than being controlled by a single gene pair. Choices A, B, and C are incorrect because polygenic traits are not specifically developed during adolescence, transmitted by the mother, or uncommon in humans. Understanding polygenic traits is essential in genetics as they demonstrate the complexity of genetic inheritance and the influence of multiple genes on a single trait.
4. The actual sets of traits that people exhibit are called their genotypes.
- A. TRUE
- B. FALSE
- C. Possibly
- D. Always
Correct answer: B
Rationale: The actual sets of traits that people exhibit are called phenotypes, not genotypes. Genotypes refer to the genetic makeup of an individual.
5. Monozygotic (MZ) twins share _________ percent of their genes.
- A. 100
- B. 75
- C. 50
- D. 25
Correct answer: A
Rationale: Monozygotic (MZ) twins share 100% of their genes because they originate from the same fertilized egg that splits into two, resulting in identical genetic material for both twins. Choice B (75%) is incorrect as it implies a partial genetic similarity, which is not the case for MZ twins. Choice C (50%) is incorrect as it suggests half of the genes are shared, which is applicable to dizygotic (DZ) twins, not MZ. Choice D (25%) is incorrect as it indicates minimal genetic sharing, which is not true for MZ twins.
