HESI Maternity 55 Questions Questions
Question 1 of 5
What is the primary role of meiosis in the production of sperm and ova?
Correct Answer: A
Rationale: The correct answer is A. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of sperm and ova. Choice B is incorrect because meiosis does not increase the chromosome number. Choice C is incorrect because meiosis creates genetically diverse gametes, not identical copies of chromosomes. Choice D is incorrect because meiosis does not primarily function to repair damaged chromosomes.
Question 2 of 5
Genotypes are solely based on genetic information.
Correct Answer: B
Rationale: The correct answer is B - FALSE. Genotypes are solely based on genetic information and do not reflect environmental influences. Phenotypes, on the other hand, result from the interaction of genetic and environmental factors. Choices A, C, and D are incorrect because genotypes are not influenced by environmental factors, and they are determined by an individual's genetic makeup.
Question 3 of 5
When do mothers usually feel the first fetal movements during pregnancy?
Correct Answer: A
Rationale: Mothers usually feel the first fetal movements, known as 'quickening,' around the 18th to 20th week of pregnancy. Feeling fetal movements during the first month is unlikely and uncommon. Therefore, option B is incorrect. Options C and D are also incorrect as mothers typically do feel fetal movements during pregnancy, just not during the first month.

Question 5 of 5
A client is receiving oxytocin by continuous IV infusion for labor induction. Which of the following interventions should the nurse include in the plan?
Correct Answer: A
Rationale: The correct answer is to increase the infusion rate every 30 to 60 minutes. This approach allows for the careful monitoring and adjustment of oxytocin administration during labor induction. Choice B is incorrect because maintaining the client in a supine position can decrease blood flow to the placenta and compromise fetal oxygenation. Choice C is incorrect as titrating the infusion rate by 4 milliunits/min is not a standard practice for oxytocin administration. Choice D is incorrect as limiting IV intake to 4 L per 24 hours is not specifically related to the administration of oxytocin for labor induction.
