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?

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. Just after delivery, a new mother tells the nurse, 'I was unsuccessful breastfeeding my first child, but I would like to try with this baby.' Which intervention is best for the LPN/LVN to implement first?

Correct answer: D

Rationale: The correct intervention is to provide immediate assistance to the mother to begin breastfeeding as soon as possible after delivery. This approach helps initiate bonding and successful breastfeeding. Taking action promptly can address the mother's desire to breastfeed and promote positive outcomes for both the mother and the newborn.

3. 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

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.

4. A 28-year-old client in active labor complains of cramps in her leg. What intervention should be implemented?

Correct answer: B

Rationale: During active labor, if a client complains of leg cramps, extending the leg and dorsiflexing the foot can help relieve the muscle cramps by stretching the affected muscles. This intervention promotes circulation and can alleviate discomfort associated with leg cramps.

5. The healthcare provider is providing preconception counseling. Which supplement should the provider recommend to help prevent the occurrence of anencephaly?

Correct answer: A

Rationale: Folic acid supplementation before and during early pregnancy is crucial for reducing the risk of neural tube defects, including anencephaly. Anencephaly is a severe birth defect in which a baby is born without parts of the brain and skull. Folic acid plays a key role in neural tube development and can significantly lower the chances of such defects when taken prior to conception and in early pregnancy.
