Nursing Elites

1. What causes sickle-cell anemia?

• A. A chromosomal abnormality.
• B. A single segment found only on the Y chromosome.
• C. A recessive gene.
• D. A decrease in estrogen levels.

Correct answer: C

Rationale: Sickle-cell anemia is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. The correct answer is C. Choice A is incorrect because sickle-cell anemia is not primarily caused by a chromosomal abnormality. Choice B is incorrect as the condition is not linked to a single segment found only on the Y chromosome. Choice D is unrelated as it mentions a decrease in estrogen levels, which is not a cause of sickle-cell anemia.

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. A client has experienced a fetal demise following a vaginal delivery at term. What should the nurse advise the client?

• A. “You can bathe and dress your baby if you’d like to.”
• B. “If you don’t hold the baby, it will make letting go much harder.”
• C. “You should name the baby so he/she can have an identity.”
• D. “I’m sure you will be able to have another baby when you’re ready.”

Correct answer: A

Rationale: After a fetal demise, allowing the parents to bathe and dress their baby can offer them a sense of closure and help them in their grieving process. This act can provide a tangible way for the parents to bond with their baby and create lasting memories. Option B is incorrect because each individual may have different emotional needs and holding the baby may not be appropriate or helpful for everyone. Option C, while well-intentioned, may not be suitable for all parents as naming the baby could be emotionally challenging. Option D is insensitive as it overlooks the grieving process of losing a baby by suggesting a replacement.

4. When assessing a woman in the first stage of labor, which clinical finding will alert the nurse that uterine contractions are effective?

• A. Dilation of the cervix.
• B. Descent of the fetus to –2 station.
• C. Rupture of the amniotic membranes.
• D. Increase in bloody show.

Correct answer: A

Rationale: During the first stage of labor, effective uterine contractions lead to cervical dilation. Dilation of the cervix is a key indicator that uterine contractions are progressing labor. Descent of the fetus to -2 station (Choice B) is related to the fetal position in the pelvis and not a direct indicator of uterine contraction effectiveness. Rupture of the amniotic membranes (Choice C) signifies the rupture of the fluid-filled sac surrounding the fetus and does not directly reflect uterine contraction effectiveness. An increase in bloody show (Choice D) can be a sign of impending labor, but it is not a direct indicator of uterine contraction effectiveness.

5. An individual’s phenotype reflects both genetic and environmental influences.

• A. phenotype
• B. chromosome
• C. allele
• D. genotype

Correct answer: A

Rationale: The correct answer is A: phenotype. A phenotype is the observable characteristics of an individual, which result from the interaction of their genotype with the environment. This interaction between genetics and the environment determines how genes are expressed and how traits are manifested in an individual. Choices B, C, and D are incorrect because chromosomes, alleles, and genotypes are components of an individual's genetic makeup, but they do not directly reflect the observable traits influenced by both genetics and the environment.
