Nursing Elites

1. The nurse is assessing a newborn who was precipitously delivered at 38 weeks' gestation. The newborn is tremulous, tachycardic, and hypertensive. Which assessment action is most important for the nurse to take?

• A. Perform a gestational age assessment.
• B. Obtain a drug screen for cocaine.
• C. Determine reactivity of neonatal reflexes.
• D. Weigh and measure the newborn.

Correct answer: B

Rationale: The correct answer is to obtain a drug screen for cocaine. Tremulousness, tachycardia, and hypertension in a newborn can be signs of neonatal abstinence syndrome, often caused by maternal drug use, such as cocaine. Identifying maternal drug use is crucial for appropriate management and treatment of the newborn.

2. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

3. A pregnant woman in the first trimester of pregnancy has hemoglobin of 8.6 g/dl and a hematocrit of 25.1%. What food should the nurse encourage this client to include in her diet?

• A. Carrots
• B. Chicken
• C. Yogurt
• D. Cheese

Correct answer: B

Rationale: During pregnancy, it is common for women to experience a drop in hemoglobin levels, leading to anemia. Chicken is a good dietary source of iron, which is essential for increasing hemoglobin levels. Iron from animal sources, such as chicken, is more readily absorbed by the body compared to plant-based sources. Therefore, encouraging the client to include chicken in her diet can help improve her hemoglobin levels and combat anemia.

4. During a well-child visit for their child, one of the parents with an autosomal dominant disorder tells the nurse, 'We don’t plan on having any more children, since the next child is likely to inherit this disorder.' How should the nurse respond?

• A. Explain that the risk of inheriting the disorder decreases by 50% with each child the couple has.
• B. Acknowledge that the next child will inherit the disorder since the first child did not.
• C. Encourage the couple to reconsider their decision since the inheritance pattern may be sex-linked.
• D. Confirm that there is a 50% chance of their future children inheriting the disorder.

Correct answer: D

Rationale: Confirming that there is a 50% chance of their future children inheriting the disorder is the correct response in this situation. Autosomal dominant disorders have a 50% chance of being passed on to each child. Providing accurate genetic counseling is essential to help the parents make informed decisions about family planning. Choices A, B, and C are incorrect. Choice A is inaccurate because the risk of inheriting an autosomal dominant disorder remains at 50% for each child regardless of the number of children the couple has. Choice B is not appropriate as it does not provide helpful information or support to the parents. Choice C is misleading because autosomal dominant disorders follow a specific inheritance pattern and are not sex-linked.

5. In developing a teaching plan for expectant parents, the nurse plans to include information about when the parents can expect the infant's fontanels to close. The LPN/LVN bases the explanation on knowledge that for the normal newborn, the

• A. anterior fontanel closes at 2 to 4 months and the posterior by the end of the first week.
• B. anterior fontanel closes at 5 to 7 months and the posterior by the end of the second week.
• C. anterior fontanel closes at 8 to 11 months and the posterior by the end of the first month.
• D. anterior fontanel closes at 12 to 18 months and the posterior by the end of the second month.

Correct answer: D

Rationale: The anterior fontanel typically closes between 12 to 18 months, while the posterior fontanel usually closes by the end of the second month. It is important for parents to know these timeframes as it helps in monitoring the normal growth and development of their newborn. Delayed closure of fontanels may indicate potential health issues, and early closure may also warrant further evaluation by healthcare providers.
