Nursing Elites

1. A newborn is being assessed by a nurse who was born post-term. Which of the following findings should the nurse expect?

• A. Nails extending over tips of fingers
• B. Large deposits of subcutaneous fat
• C. Pale, translucent skin
• D. Thin covering of fine hair on shoulders and back

Correct answer: A

Rationale: Post-term newborns often have longer nails that extend over the tips of their fingers due to the extended gestation period. This occurs because the baby continues to grow in utero past the typical 40 weeks of gestation. Choices B, C, and D are incorrect as large deposits of subcutaneous fat, pale translucent skin, and a thin covering of fine hair on shoulders and back are not typically associated with post-term newborns. Longer nails are a common finding in post-term newborns due to the prolonged time spent in the womb, allowing for more nail growth compared to infants born at term.

2. Which of the following statements is true of a sperm cell?

• A. A sperm cell is significantly larger than an egg cell.
• B. A sperm cell contains two Y chromosomes.
• C. A sperm cell travels randomly inside a woman’s reproductive tract.
• D. A sperm cell is one of the smallest types of cells in the body.

Correct answer: D

Rationale: The correct answer is D. A sperm cell is indeed one of the smallest cells in the human body, much smaller than an egg cell. Choice A is incorrect as sperm cells are much smaller than egg cells. Choice B is incorrect because a sperm cell carries either an X or a Y chromosome, not two Y chromosomes. Choice C is incorrect since sperm cells move in a purposeful manner guided by various factors within a woman's reproductive tract, not randomly.

3. Rubella, also called German measles, is a viral infection passed from the mother to the fetus that can cause birth defects such as deafness, intellectual disabilities, blindness, and heart disease in the embryo.

• A. Rubella
• B. Syphilis
• C. Cystic fibrosis
• D. Phenylketonuria

Correct answer: A

Rationale: Rubella, also known as German measles, is a viral infection that can lead to severe birth defects when contracted by a mother during pregnancy. Rubella is the correct answer because it is specifically associated with causing birth defects such as deafness, intellectual disabilities, blindness, and heart disease in the embryo. Syphilis (Choice B) can be passed from mother to fetus but does not cause the mentioned birth defects associated with Rubella. Cystic fibrosis (Choice C) and Phenylketonuria (Choice D) are genetic conditions and not infections transmitted from mother to fetus, making them incorrect choices in this context.

4. Following an amniocentesis, a nurse is caring for a client. The nurse should observe the client for which of the following complications?

• A. Hyperemesis
• B. Proteinuria
• C. Hypoxia
• D. Hemorrhage

Correct answer: D

Rationale: After an amniocentesis, the nurse should monitor the client for potential complications, with hemorrhage being a significant concern due to the invasive nature of the procedure. Hyperemesis (severe vomiting), proteinuria (excessive protein in the urine), and hypoxia (low oxygen levels) are not typically associated with amniocentesis and are less likely to occur compared to hemorrhage, which is a more common complication that requires prompt recognition and intervention.

5. Which of the following most accurately describes the function of genes?

• A. They regulate the development of traits.
• B. They prevent foreign particles from entering the body.
• C. They work together with lutein to influence development.
• D. They transfer oxygen from the bloodstream to other parts of the body.

Correct answer: A

Rationale: The correct answer is A: 'They regulate the development of traits.' Genes play a crucial role in regulating the development of traits by encoding proteins that control various bodily functions and characteristics. This process involves gene expression and the production of proteins that ultimately determine an individual's traits. Choice B is incorrect because genes do not have a direct role in preventing foreign particles from entering the body; this function is primarily carried out by the immune system. Choice C is incorrect as genes do not specifically work with lutein to influence development; genes operate independently to regulate trait expression. Choice D is incorrect as genes are not responsible for transferring oxygen in the bloodstream; this function is carried out by red blood cells and hemoglobin.
