Nursing Elites

1. A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?

• A. The thyroxine level is low because the TSH level is high.
• B. High thyroxine levels do not normally occur in breastfeeding infants.
• C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
• D. The TSH is high because of the low production of T4 by the thyroid.

Correct answer: D

Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.

2. A multiparous client is involuntarily pushing while being wheeled into the labor triage area. The nurse observes the fetal head presenting at the perineum. Which action should the nurse take?

• A. Support the infant as it emerges.
• B. Review prenatal laboratory results.
• C. Obtain fetal heart tones.
• D. Apply suprapubic pressure.

Correct answer: A

Rationale: When the fetal head is visible at the perineum, the priority is to support the infant's birth to prevent injury. Providing support as the infant emerges helps ensure a safe delivery process and reduces the risk of complications associated with rapid or uncontrolled birth.

3. A pregnant woman in the first trimester of pregnancy has hemoglobin of 8.6 g/dl and a hematocrit of 25.1%. What food should the nurse encourage this client to include in her diet?

• A. Carrots
• B. Chicken
• C. Yogurt
• D. Cheese

Correct answer: B

Rationale: During pregnancy, it is common for women to experience a drop in hemoglobin levels, leading to anemia. Chicken is a good dietary source of iron, which is essential for increasing hemoglobin levels. Iron from animal sources, such as chicken, is more readily absorbed by the body compared to plant-based sources. Therefore, encouraging the client to include chicken in her diet can help improve her hemoglobin levels and combat anemia.

4. During a prenatal visit, the LPN/LVN discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: When mothers smoke during pregnancy, it is associated with intrauterine growth restriction, which leads to lower birth weights in infants. Maternal smoking can restrict the flow of oxygen and nutrients to the fetus, affecting its growth and development. This can result in babies being born with lower birth weights, which can have various health implications for the newborn. Choices A, C, and D are incorrect as smoking during pregnancy is primarily linked to intrauterine growth restriction and lower birth weights in infants, rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

5. A new mother asks the LPN/LVN, 'How do I know that my daughter is getting enough breast milk?' Which explanation should the nurse provide?

• A. Weigh the baby daily, and if she is gaining weight, she is eating enough.
• B. Your milk is sufficient if the baby is voiding pale straw-colored urine 6 to 10 times a day.
• C. Offer the baby extra bottle milk after her feeding, and see if she is still hungry.
• D. If you're concerned, you might consider bottle feeding so that you can monitor her intake.

Correct answer: B

Rationale: The correct answer is B. Adequate voiding is a sign that the baby is receiving enough milk. Pale straw-colored urine 6 to 10 times a day indicates proper hydration and nutrition. This is a reliable indicator of adequate breast milk intake for the infant. Choice A is incorrect because weight gain alone may not always indicate sufficient milk intake. Choice C is incorrect because supplementing with bottle milk can interfere with establishing breastfeeding. Choice D is incorrect as it suggests switching to bottle feeding, which is not necessary if the baby is latching and voiding well.
