Nursing Elites

1. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

2. When calculating the Apgar score of a newborn at 1 minute after delivery, which of the following findings would result in a score of 6?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: C

Rationale: The Apgar score is calculated based on five parameters: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the newborn's findings at 1 minute after delivery indicate a heart rate >100/min (2 points), slow, weak cry (1 point), some flexion of extremities (1 point), grimace in response to suctioning (1 point), and body pink with blue extremities (1 point). Adding these points together results in a total Apgar score of 6, reflecting the newborn's initial assessment for their overall well-being. Choice A (4) is too low based on the given findings, while Choice B (5) is also lower than the correct score of 6. Choice D (7) is too high as it would require additional findings to reach that score.

3. A client who is at 24 weeks of gestation is scheduled for a 1-hour glucose tolerance test. Which of the following statements should the nurse include in her teaching?

• A. You will need to drink the glucose solution 1 hour prior to the test.
• B. Limit your carbohydrate intake for 24 hours prior to the test.
• C. A blood glucose of 130 to 140 mg/dL is considered a positive screening result.
• D. You will need to fast for 8 hours prior to the test.

Correct answer: C

Rationale: The correct statement to include in the teaching for a client scheduled for a 1-hour glucose tolerance test at 24 weeks of gestation is that a blood glucose level of 130 to 140 mg/dL is considered a positive screening result. This range indicates a potential issue with glucose metabolism and would prompt the need for a follow-up 3-hour glucose tolerance test to confirm the diagnosis of gestational diabetes mellitus. Choices A, B, and D are incorrect. In a 1-hour glucose tolerance test, the glucose solution is typically consumed within a specific timeframe before the test, not necessarily 1 hour prior. There is usually no specific requirement to limit carbohydrate intake for 24 hours prior to the test. Fasting for 8 hours prior to the test is more common for a fasting glucose test, not a 1-hour glucose tolerance test.

4. During an assessment, a client at 26 weeks of gestation presents with which of the following clinical manifestations that should be reported to the provider?

• A. Leukorrhea
• B. Supine hypotension
• C. Periodic numbness of the fingers
• D. Decreased urine output

Correct answer: D

Rationale: During pregnancy, decreased urine output can be indicative of decreased renal perfusion and impaired fetal well-being. It can also be a sign of preeclampsia when associated with symptoms like increased blood pressure, proteinuria, and decreased fetal activity. Therefore, the nurse should promptly report this finding to the healthcare provider for further evaluation and management. Leukorrhea is a common finding in pregnancy and not typically concerning. Supine hypotension and periodic numbness of the fingers can be managed by changing positions or adjusting posture and are not as urgent as decreased urine output in this context.

5. When advising a woman considering pregnancy on nutritional needs to reduce the risk of giving birth to a newborn with a neural tube defect, what information should the nurse include?

• A. Limit alcohol consumption.
• B. Increase intake of iron-rich foods.
• C. Consume foods fortified with folic acid.
• D. Avoid foods containing aspartame.

Correct answer: C

Rationale: The correct answer is C: Consume foods fortified with folic acid. Folic acid plays a crucial role in preventing neural tube defects. It is advised to consume foods fortified with folic acid or take a supplement containing at least 400 micrograms of folic acid daily. This nutrient is essential for the developing fetus and can significantly reduce the risk of neural tube defects when taken before and during early pregnancy. Choices A, B, and D are incorrect. While limiting alcohol consumption is important during pregnancy, it is not directly related to reducing the risk of neural tube defects. Increasing intake of iron-rich foods is essential for preventing anemia but is not specifically linked to neural tube defects. Avoiding foods containing aspartame is generally recommended, but it is not directly related to reducing the risk of neural tube defects.
