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. A client is scheduled for a cesarean birth based on fetal lung maturity. Which finding indicates that the fetal lungs are mature?

• A. Absence of Phosphatidylglycerol (PG)
• B. Biophysical profile score of 8
• C. Lecithin/sphingomyelin (L/S) ratio of 2:1
• D. Reactive nonstress test

Correct answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.

3. A client who is at 12 weeks of gestation is reviewing a new prescription of ferrous sulfate. Which of the following statements by the client indicates understanding of the teaching?

• A. I will take this pill with my breakfast.
• B. I will take this medication with a glass of milk.
• C. I plan to drink more orange juice while taking this pill.
• D. I plan to add more calcium-rich foods to my diet while taking this medication.

Correct answer: C

Rationale: The correct answer is C. Taking iron supplements with orange juice, which contains vitamin C, enhances the absorption of iron, making the treatment more effective. Choices A, B, and D are incorrect because taking ferrous sulfate with milk, calcium-rich foods, or breakfast may hinder iron absorption due to interactions with calcium or other substances that compete with iron absorption.

4. A client who received carboprost for postpartum hemorrhage is being assessed by a nurse. Which of the following findings is an adverse effect of this medication?

• A. Hypertension
• B. Hypothermia
• C. Constipation
• D. Muscle weakness

Correct answer: A

Rationale: The correct answer is A: Hypertension. Carboprost is a vasoconstrictor medication used to control postpartum hemorrhage by contracting the uterus. One of the adverse effects of carboprost is hypertension due to its vasoconstrictive properties. Hypertension can occur as a result of increased peripheral vascular resistance. Choices B, C, and D are incorrect. Hypothermia, constipation, and muscle weakness are not typically associated with the administration of carboprost. It is crucial for the nurse to monitor the client's blood pressure closely while on carboprost to promptly detect and manage hypertension.

5. A woman in a women's health clinic is receiving teaching about nutritional intake during her 8th week of gestation. The healthcare provider should advise the woman to increase her daily intake of which of the following nutrients?

• A. Calcium
• B. Vitamin E
• C. Iron
• D. Vitamin D

Correct answer: C

Rationale: During pregnancy, the recommended daily iron intake is higher compared to non-pregnant women. Pregnant women should aim for 27 mg/day of iron, while non-pregnant women require 15 mg/day if under 19 years old and 18 mg/day if between 19 and 50 years old. Iron is essential during pregnancy to support the increased blood volume and ensure the proper oxygen supply to the fetus. Calcium is important for bone health but does not need a significant increase during early pregnancy. Vitamin E and Vitamin D are important but do not have specific increases recommended during the 8th week of gestation.
