1. When both of the alleles for a trait, such as hair color, are the same, the person is said to be _____ for that trait.

Correct answer: C

Rationale: A person is homozygous for a trait when they have two identical alleles for that trait. In this case, both alleles are the same, indicating a homozygous genotype. Choice A, 'monozygous,' is incorrect as it refers to identical twins originating from a single fertilized egg. Choice B, 'dizygous,' is also incorrect as it refers to fraternal twins or individuals that develop from two separate fertilized eggs. Choice D, 'hemizygous,' is incorrect because it describes a genetic condition where only one allele is present in a diploid organism, typically related to genes on the sex chromosomes.

2. What information should the nurse include when teaching a client at 41 weeks of gestation about a non-stress test?

Correct answer: B

Rationale: The correct answer is B: 'This test will determine the adequacy of placental perfusion.' The non-stress test is used to assess fetal well-being by monitoring the fetal heart rate in response to its own movements. It helps determine if the fetus is receiving enough oxygen and nutrients through placental perfusion. Choice A is incorrect because confirming fetal lung maturity is typically determined through tests like amniocentesis, not the non-stress test. Choice C is incorrect because detecting fetal infection is not the primary purpose of a non-stress test. Choice D is incorrect because predicting maternal readiness for labor is not the purpose of the non-stress test; it focuses on fetal well-being.

3. Which of the following statements about Rh incompatibility is true?

Correct answer: D

Rationale: Rh incompatibility occurs when the mother's antibodies attack the fetus's red blood cells, leading to serious complications, usually in subsequent pregnancies. Choice A is incorrect because Rh incompatibility often occurs in subsequent pregnancies, not necessarily the first one. Choice B is incorrect as Rh incompatibility does not render a woman infertile but can lead to complications during pregnancies. Choice C is incorrect as Rh incompatibility is not carried by a sex chromosome but involves the Rh factor on red blood cells.

4. The nurse is planning discharge teaching for four mothers. Which postpartum client is at highest risk for psychological difficulties during the postpartum period?

Correct answer: A

Rationale: A primiparous woman who has recently migrated to the US with her spouse is at the highest risk for psychological difficulties during the postpartum period. Recent migration and adjustment to a new environment can increase the risk of postpartum depression, especially when combined with the challenges of being a new mother. Choice B, a multiparous client living with her husband and his family, may have social support from family members, which can be protective against psychological difficulties. Choice C, a multiparous female with a large family living in a community, also indicates potential social support. Choice D, a primiparous adolescent living at home with her parents and significant other, may have a support system in place with her family and significant other.

5. A client at 38 weeks gestation is admitted to labor and delivery with a complaint of contractions 5 minutes apart. While the client is in the bathroom changing into a hospital gown, the nurse hears the noise of a baby. What should the nurse do first?

Correct answer: B

Rationale: Inspecting the client's perineum immediately is necessary to assess if the baby is being delivered, which would require urgent action. Pushing the call light for help (Choice A) may delay the assessment and immediate action needed. Notifying a healthcare provider (Choice C) might cause further delays, as the situation requires urgent attention. Turning on the infant warmer (Choice D) is not the priority; ensuring safe delivery and assessment of the baby's condition come first.
