Nursing Elites

1. 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.

2. In the prenatal record, the nurse should record for the pregnant client who has a 3-year-old child at home, a term birth, a miscarriage at 10 weeks’ gestation, and a set of twins who died within 24 hours:

• A. Gravida 2, para 1.
• B. Gravida 3, para 3.
• C. Gravida 4, para 2.
• D. Gravida 5, para 4.

Correct answer: C

Rationale: The correct answer is C: 'Gravida 4, para 2.' Gravida refers to the total number of pregnancies, including the current one. In this case, the client has been pregnant a total of 4 times, so gravida is 4. Para is the number of pregnancies that have reached viability, which is 2 in this case. The client has had a term birth and a set of twins who died within 24 hours, totaling 2 pregnancies that reached viability. Choices A, B, and D are incorrect because they do not accurately reflect the client's obstetric history based on the information provided.

3. What is the purpose of amniocentesis?

• A. To induce abortion
• B. To detect genetic abnormalities in the fetus
• C. To determine the baby's gender
• D. To monitor fetal growth

Correct answer: B

Rationale: Amniocentesis is a diagnostic procedure used to detect genetic abnormalities in the fetus, such as chromosomal disorders like Down syndrome. It is not performed to induce abortion. The primary purpose of amniocentesis is to assess the genetic health of the fetus, not to determine the baby's gender (Choice C). While amniocentesis can provide information about the baby's health and development, it is not primarily used for monitoring fetal growth (Choice D). Therefore, the correct answer is B.

4. A new parent is receiving discharge teaching about car seat safety from a nurse. Which statement by the parent indicates an understanding of the teaching?

• A. “I should position my baby’s car seat at a 45-degree angle in the car.”
• B. “I should place the car seat rear-facing until my baby is 12 months old.”
• C. “I should place the harness snugly in a slot above my baby’s shoulders.”
• D. “I should position the retainer clip at the top of my baby’s abdomen.”

Correct answer: A

Rationale: The correct answer is A. Positioning the car seat at a 45-degree angle is crucial to prevent the baby's head from falling forward, which can obstruct the airway. Choice B is incorrect because the recommendation is to keep the car seat rear-facing until the baby reaches the height or weight limit set by the car seat manufacturer, typically beyond 12 months. Choice C is incorrect as the harness should be snugly placed at or below the baby's shoulders, not above. Choice D is incorrect as the retainer clip should be positioned at armpit level to secure the harness straps properly.

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

• A. Rh incompatibility occurs most commonly during a woman’s first pregnancy.
• B. Rh incompatibility is an untreatable condition that leaves a woman infertile for the rest of her life.
• C. Rh incompatibility is an abnormality that is transmitted from generation to generation and carried by a sex chromosome.
• D. Rh incompatibility occurs due to antibodies transmitted to a fetus during subsequent deliveries causing brain damage or death.

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.
