HESI Maternal Newborn Questions

Question 1 of 5

According to a study in 2014 by Skakkebaek et al., who among the following is most likely to have gynecomastia?

Correct Answer: C

Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY) and typically have reduced testosterone levels, which can lead to gynecomastia (enlarged breasts). This condition is not usually associated with Down syndrome (choice A), XYY syndrome (choice B), or Turner syndrome (choice D), making them less likely to have gynecomastia.

Question 2 of 5

A nurse is developing an educational program about hemolytic diseases in newborns for a group of newly licensed nurses. Which of the following genetic information should the nurse include in the program as a cause of hemolytic disease?

Correct Answer: B

Rationale: The correct answer is B: 'The mother is Rh negative, and the father is Rh positive.' Hemolytic disease of the newborn occurs when an Rh-negative mother carries an Rh-positive fetus, leading to Rh incompatibility. In this scenario, the mother produces antibodies against the Rh antigen present in the fetus, which can result in hemolysis of the fetal red blood cells. Choices A, C, and D do not describe the Rh incompatibility that leads to hemolytic disease in newborns. Therefore, they are incorrect.

Question 3 of 5

In contrast to placenta previa, what is the most prevalent clinical manifestation of abruptio placentae?

Correct Answer: B

Rationale: The correct answer is B: Intense abdominal pain. Pain is absent with placenta previa but can be agonizing with abruptio placentae. While bleeding may be present in varying degrees for both placental conditions, intense abdominal pain is a distinguishing feature of abruptio placentae. Uterine activity and cramping may be present with both placental conditions, but they are not the most prevalent clinical manifestation of abruptio placentae.

Question 4 of 5

In the context of an average ejaculation, which of the following statements is true about sperm?

Correct Answer: C

Rationale: Out of millions of sperm released during ejaculation, only a small fraction, about 1 in 1,000, will approach the ovum. This statement is true as sperm face many obstacles and challenges on their journey to reach and fertilize an ovum. Choice A is incorrect because the average count of sperm in an ejaculate is typically in the millions, not billions. Choice B is incorrect as sperm do not find the ovum by following the current of fluid; they navigate using other mechanisms. Choice D is incorrect because while some sperm may move randomly in the vagina, the ones that approach the ovum do so through a more purposeful and directed movement.

Question 5 of 5

_________ is self-propulsion.

Correct Answer: C

Rationale: The correct answer is 'Motility.' Motility refers to the ability of cells or organisms to move by themselves, often through the use of specialized structures like flagella or cilia. Mitosis (Choice A) and Meiosis (Choice B) are processes related to cell division and genetic recombination, respectively, not self-propulsion. Mutation (Choice D) refers to changes in the DNA sequence and is not related to self-propulsion.
