Nursing Elites

1. 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.

2. 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.

3. A client who is at 36 weeks of gestation and has a prescription for a nonstress test is being taught by a nurse. Which of the following statements should the nurse include in the teaching?

• A. You will receive IV fluid before this test.
• B. The procedure will take approximately 10 to 15 minutes.
• C. You will be offered orange juice to drink during the test.
• D. You will need to sign an informed consent form before each test.

Correct answer: C

Rationale: The correct statement the nurse should include in the teaching is that the client will be offered orange juice to drink during the nonstress test. This is because offering the client orange juice, or another beverage high in glucose, will help stimulate the fetus during the procedure, aiding in obtaining accurate results. Choice A is incorrect because IV fluid is not typically administered before a nonstress test. Choice B is incorrect as the procedure usually takes around 20 to 40 minutes. Choice D is incorrect as informed consent is typically obtained once for the procedure, not before each individual test.

4. When caring for a client suspected of having hyperemesis gravidarum, which finding is a manifestation of this condition?

• A. Hgb 12.2 g/dL
• B. Urine ketones present
• C. Alanine aminotransferase 20 IU/L
• D. Blood glucose 114 mg/dL

Correct answer: B

Rationale: The correct answer is B: Urine ketones present. The presence of urine ketones indicates dehydration, which is a common manifestation of hyperemesis gravidarum. Hyperemesis gravidarum is characterized by severe nausea, vomiting, weight loss, and electrolyte imbalances due to dehydration. Monitoring for ketonuria helps assess the degree of dehydration in clients with this condition. Choices A, C, and D are incorrect because hemoglobin level, alanine aminotransferase level, and blood glucose level are not specific manifestations of hyperemesis gravidarum. While these laboratory values may be abnormal in some cases, they are not typically used to diagnose or assess the condition.

5. 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.
