Maternity HESI Practice Questions

1. The _____ is the inner layer of the embryo from which the lungs and digestive system develop.

Correct answer: C

Rationale: The endoderm is the correct answer. It is the innermost layer of the embryo that gives rise to organs such as the lungs, digestive system, liver, and pancreas. The neural tube (Choice A) forms the brain and spinal cord, not the lungs or digestive system. Mesoderm (Choice B) develops into structures like muscles, bones, and circulatory system, not the lungs or digestive system. The umbilical cord (Choice D) serves as a connection between the embryo and the placenta, providing nutrients and oxygen, but it is not the layer from which lungs and digestive system develop.

2. The nurse is receiving a report for a laboring client who arrived in the emergency center with ruptured membranes that the client did not recognize. Which is the priority nursing action to implement when the client is admitted to the labor and delivery suite?

Correct answer: C

Rationale: The priority nursing action when a client with ruptured membranes is admitted to the labor and delivery suite is to take the client's temperature. This is crucial to assess for infection, especially when the duration of membrane rupture is unknown. Beginning a pad count, preparing to start an IV, and monitoring amniotic fluid for meconium are important actions but are not as immediate or critical as assessing for infection through temperature measurement.

3. According to a study in 2013 by van Gameren-Oosterom, individuals with Down syndrome:

Correct answer: C

Rationale: The correct answer is C. According to a study in 2013 by van Gameren-Oosterom, individuals with Down syndrome often exhibit deficits in cognitive development. This is a common characteristic of Down syndrome, along with other health challenges. Choice A is incorrect because individuals with Down syndrome are at a higher risk of cardiovascular problems, contrary to being unlikely to die from them. Choice B is incorrect as Down syndrome is associated with specific characteristic features such as distinctive facial characteristics, making the statement that they have no specific features incorrect. Choice D is incorrect as individuals with Down syndrome have an extra copy of chromosome 21, resulting in a total of 47 chromosomes, not 46.

4. Monozygotic (MZ) twins share _________ percent of their genes.

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.

5. When should a nurse on a labor and delivery unit instruct a newly licensed nurse to don gloves for a procedure?

Correct answer: B

Rationale: The correct answer is B: Performing a newborn's initial bath. Gloves should be worn during this procedure to protect against exposure to body fluids, such as amniotic fluid or blood. Assisting a mother with breastfeeding (Choice A) does not typically require gloves unless there are specific reasons for infection control. Administering vaccines (Choice C) and performing umbilical cord care (Choice D) are procedures that may require hand hygiene but not necessarily gloves, unless there is active bleeding or potential exposure to body fluids. The initial bath involves direct contact with body fluids, making it crucial to wear gloves for protection.
