HESI Focus on Maternity Exam Questions
Question 1 of 5
The healthcare provider is preparing to administer phytonadione (vitamin K) to a newborn. Which statement made by the parents indicates understanding why the healthcare provider is administering this medication?
Correct Answer: D
Rationale: The correct answer is D because phytonadione (vitamin K) is administered to newborns to prevent hemorrhagic disease due to their low levels of vitamin K, which is essential for blood clotting. Choice A is incorrect as vitamin K administration is not related to improving dietary intake. Choice B is incorrect as vitamin K doesn't stimulate the immune system. Choice C is incorrect as vitamin K is not given to help an immature liver, but rather to prevent hemorrhagic disorders.
Question 2 of 5
Do neural tube defects cause an elevation in the alpha-fetoprotein (AFP) level in the mother's blood?
Correct Answer: A
Rationale: Yes, neural tube defects can cause an elevation in AFP levels in the mother's blood. AFP levels are often used as a screening marker during pregnancy to detect neural tube defects. Choice B is incorrect because an elevation in AFP levels can indeed occur in the presence of neural tube defects. Choice C is not the best option as it leaves room for uncertainty when the relationship between neural tube defects and AFP elevation is well-established. Choice D is incorrect as neural tube defects are known to influence AFP levels in the maternal blood.
Question 3 of 5
What nursing action should the nurse implement for a 3-hour-old male infant who presents with cyanotic hands and feet, an axillary temperature of 96.5�F (35.8�C), a respiratory rate of 40 breaths per minute, and a heart rate of 165 beats per minute?
Correct Answer: B
Rationale: The correct nursing action is to gradually warm the infant under a radiant heat source. The infant is presenting with signs of cold stress, indicated by cyanotic extremities and a low body temperature. Gradual warming is crucial to stabilize the infant's temperature and prevent further complications. Administering oxygen, notifying the pediatrician, or performing a heel-stick are not the priority actions in this scenario and may not address the immediate need to raise the infant's body temperature.
Question 4 of 5
Which of the following conditions is considered a multifactorial problem?
Correct Answer: C
Rationale: The correct answer is 'Diabetes mellitus' because it is a multifactorial disease, influenced by both genetic predisposition and environmental factors. Cystic fibrosis (choice A) is primarily a genetic disorder caused by mutations in the CFTR gene. Down syndrome (choice B) is due to an extra copy of chromosome 21. XYY syndrome (choice D) is a genetic condition where males have an extra Y chromosome. These conditions are not considered multifactorial as their origins are primarily genetic.
Question 5 of 5
As women reach the end of their childbearing years, does ovulation become more regular?
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.
