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. A newborn who was born at 38 weeks of gestation, weighs 3,200 g, and is in the 60th percentile for weight should be classified as which of the following?

• A. Low birth weight
• B. Appropriate for gestational age
• C. Small for gestational age
• D. Large for gestational age

Correct answer: B

Rationale: The classification of a newborn as appropriate for gestational age is determined by considering the weight and gestational age. In this case, the newborn's weight falls within the normal range for the gestational age, indicating that the newborn is appropriately sized for the length of time spent in the womb. Choice A, 'Low birth weight,' is incorrect as the newborn's weight is within the normal range. Choice C, 'Small for gestational age,' is incorrect because the newborn's weight is not below the 10th percentile for gestational age. Choice D, 'Large for gestational age,' is incorrect as the newborn's weight is not above the 90th percentile, rather falling within the 60th percentile which is considered normal.

3. While caring for a newborn undergoing phototherapy to treat hyperbilirubinemia, which of the following actions should the nurse take?

• A. Cover the newborn's eyes with an opaque eye mask while under the phototherapy light.
• B. Keep the newborn in a shirt while under the phototherapy light.
• C. Apply a light moisturizing lotion to the newborn's skin.
• D. Turn and reposition the newborn every 4 hours while undergoing phototherapy.

Correct answer: A

Rationale: It is crucial to cover the newborn's eyes with an opaque eye mask to prevent damage to the retinas and corneas from the phototherapy light. The eyes are particularly sensitive to the light used in phototherapy, and shielding them helps protect the newborn's delicate eyes from potential harm. Choice B is incorrect because the newborn should be undressed to maximize skin exposure to the phototherapy light. Choice C is incorrect because lotions or oils can interfere with the effectiveness of phototherapy. Choice D is incorrect because the newborn should be kept as still as possible to maximize exposure to the light.

4. When educating a pregnant client about potential complications, which manifestation should the nurse emphasize reporting to the provider promptly?

• A. Vaginal bleeding
• B. Swelling of the ankles
• C. Heartburn after eating
• D. Lightheadedness when lying on back

Correct answer: A

Rationale: Vaginal bleeding during pregnancy is a concerning sign that could indicate serious complications like miscarriage or placental issues. Prompt reporting to the healthcare provider is crucial for timely evaluation and management to ensure the best outcomes for both the mother and the baby. Swelling of the ankles (choice B), heartburn after eating (choice C), and lightheadedness when lying on the back (choice D) are common discomforts during pregnancy but are not typically associated with serious complications that require immediate attention.

5. During active labor, a nurse notes tachycardia on the external fetal monitor tracing. Which of the following conditions should the nurse identify as a potential cause of the heart rate?

• A. Maternal fever
• B. Fetal heart failure
• C. Maternal hypoglycemia
• D. Fetal head compression

Correct answer: A

Rationale: Maternal fever can lead to fetal tachycardia due to the transmission of maternal fever to the fetus. This can result in an increased fetal heart rate, making it the correct potential cause in this scenario. Fetal heart failure (choice B) would typically present with bradycardia rather than tachycardia, making it an incorrect choice. Maternal hypoglycemia (choice C) is more likely to cause fetal distress rather than tachycardia. Fetal head compression (choice D) may lead to decelerations in the fetal heart rate pattern, but not necessarily tachycardia.
