HESI Focus on Maternity Exam
1. As women reach the end of their childbearing years, does ovulation become more regular?
- A. TRUE
- B. FALSE
- C. Rarely
- D. Always
Correct answer: B
Rationale: The correct answer is B: FALSE. As women age and reach the end of their childbearing years, ovulation becomes less regular due to hormonal changes associated with menopause. This can result in irregular ovulation patterns or even the cessation of ovulation entirely. Choice A is incorrect because ovulation does not become more regular with age. Choices C and D are also incorrect as they do not accurately reflect the changes in ovulation patterns that occur as women approach the end of their childbearing years.
2. 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.
3. Which of the following statements is true of sickle-cell anemia?
- A. It is typically managed with treatments such as pain relief medications.
- B. It is caused by a mutation in the beta-globin gene.
- C. It leads to the obstruction of small blood vessels and decreased oxygen delivery.
- D. It is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent.
Correct answer: C
Rationale: The correct answer is C. Sickle-cell anemia results from a mutation in the beta-globin gene, causing red blood cells to become sickle-shaped. These misshapen cells can obstruct small blood vessels, leading to reduced oxygen delivery to tissues. Choices A, B, and D are incorrect because sickle-cell anemia is typically managed with treatments such as pain relief medications, hydration, and in severe cases, blood transfusions. It is caused by a specific mutation in the beta-globin gene, not by the inability to metabolize phenylalanine. Additionally, sickle-cell anemia is more prevalent in individuals of African, Mediterranean, Middle Eastern, and Indian descent, not exclusive to any specific gender.
4. 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.
5. Does the probability of having a child with Down’s syndrome increase with the age of the parents?
- A. TRUE
- B. FALSE
- C. Sometimes
- D. Never
Correct answer: A
Rationale: The correct answer is A: TRUE. Advanced parental age, particularly maternal age, is associated with an increased risk of Down's syndrome in offspring. As parents get older, the likelihood of having a child with Down's syndrome increases. Choices B, C, and D are incorrect because the risk of Down's syndrome is known to rise with parental age, especially maternal age, due to the increased likelihood of chromosomal abnormalities during egg formation.
