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. A client experiencing preterm labor is being taught about terbutaline by a nurse. Which statement by the client indicates an understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. Terbutaline is a beta-adrenergic agonist used to stop preterm labor. One of its common side effects is heart palpitations due to its action on beta receptors in the heart. Choices B and C are incorrect because blurred vision and ringing in the ears are not common side effects of terbutaline. Choice D is irrelevant to the side effects of terbutaline.

3. What is the most critical action in caring for the newborn immediately after birth?

Correct answer: A

Rationale: The most critical action in caring for the newborn immediately after birth is keeping the airway clear. This is essential to ensure that the newborn can breathe effectively and prevent any respiratory distress. Fostering parent-newborn attachment, although important, is not the most critical action immediately after birth. Drying the newborn and wrapping the infant in a blanket is important for temperature regulation but is not as critical as maintaining a clear airway. Administering eye drops and vitamin K is typically done later and is not the most critical action immediately after birth.

4. Which of the following pairs share 100% of their genes?

Correct answer: D

Rationale: The correct answer is Monozygotic (MZ) twins. Monozygotic twins, also known as identical twins, share 100% of their genes because they originate from the same fertilized egg that splits into two. Fraternal twins (choice B), also known as dizygotic (DZ) twins (choice C), result from two separate fertilized eggs and share approximately 50% of their genes. Biovular twins (choice A) is not a term used in genetics and does not describe a type of twinning.

5. The _________ is the hollow organ within females in which the embryo and fetus develop.

Correct answer: C

Rationale: The correct answer is C: uterus. The uterus is the organ where the embryo implants and the fetus develops during pregnancy. The placenta (choice A) is an organ that develops during pregnancy and provides nutrients and oxygen to the fetus, but it is not the organ where the embryo and fetus physically develop. The ovum (choice B) is the female reproductive cell or egg that is fertilized by the sperm to form an embryo, but it is not the organ where the embryo and fetus develop. The amniotic sac (choice D) is a membrane filled with amniotic fluid that surrounds and protects the fetus, but it is not the organ where the embryo and fetus physically develop.
