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 should a provider order a maternal serum alpha-fetoprotein (MSAFP) screening for pregnant clients?

• A. A client who has mitral valve prolapse
• B. A client who has been exposed to AIDS
• C. All pregnant clients
• D. A client who has a history of preterm labor

Correct answer: C

Rationale: Maternal serum alpha-fetoprotein (MSAFP) screening is recommended for all pregnant clients to assess the risk of neural tube defects. It is a routine screening test used to detect increased levels of alpha-fetoprotein in maternal blood, which may indicate a higher risk for conditions such as neural tube defects in the developing fetus. Therefore, all pregnant clients, regardless of their medical history or risk factors, should undergo MSAFP screening as part of routine prenatal care. Choices A, B, and D are incorrect because the MSAFP screening is not specific to certain medical conditions or histories; it is a standard screening procedure for all pregnant individuals to evaluate neural tube defect risk in the fetus.

3. 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.

4. A newborn is noted to have secretions bubbling out of the nose and mouth after delivery. What is the nurse's priority action?

• A. Suction the nose with a bulb syringe.
• B. Suction the mouth with a bulb syringe.
• C. Use a suction catheter with low negative pressure.
• D. Turn the newborn on their side.

Correct answer: B

Rationale: The priority action for the nurse is to suction the mouth with a bulb syringe. Suctioning the mouth first is crucial to prevent aspiration and ensure the airway is clear, which takes precedence over suctioning the nose. This intervention helps maintain a patent airway and promotes adequate breathing in the newborn. Using a suction catheter with low negative pressure may not be appropriate as the newborn needs a gentle suction method like a bulb syringe. Turning the newborn on their side is important if there is a risk of aspiration, but clearing the mouth of secretions should be the priority to establish a clear airway.

5. A client who is pregnant states that her last menstrual period was April 1st. What is the client's estimated date of delivery?

• A. January 8
• B. January 15
• C. February 8
• D. February 15

Correct answer: A

Rationale: To calculate the estimated date of delivery, add 7 days to the first day of the last menstrual period (April 1st), which gives April 8th. Then, count forward 9 months from April 8th, leading to January 8th as the estimated date of delivery. Choice A is correct. Choice B is incorrect because it is exactly 9 months from the last menstrual period without accounting for the additional 7 days. Choices C and D are incorrect as they fall in February, which is beyond the 9-month period from the last menstrual period.
