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. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

3. What is the priority nursing assessment immediately following the birth of an infant with esophageal atresia and a tracheoesophageal (TE) fistula?

• A. Body temperature.
• B. Level of pain.
• C. Time of first void.
• D. Number of vessels in the cord.

Correct answer: D

Rationale: The priority nursing assessment immediately following the birth of an infant with esophageal atresia and a tracheoesophageal (TE) fistula is to check the number of vessels in the cord. This assessment is crucial to identify any potential anomalies related to the TE fistula, as abnormalities in the cord vessels may indicate associated congenital anomalies that need immediate attention.

4. A woman at 36-weeks' gestation who is Rh negative is admitted to labor and delivery reporting abdominal cramping. She is placed on strict bedrest, and the fetal heart rate and contraction pattern are monitored with an external fetal monitor. The nurse notes a large amount of bright red vaginal bleeding. Which nursing intervention has the highest priority?

• A. Perform a sterile vaginal examination to determine dilatation.
• B. Determine fetal position by performing Leopold maneuvers.
• C. Assess the fetal heart rate and client's contraction pattern.
• D. Confirm Rh and Coombs status for Rho(D) immunoglobulin administration.

Correct answer: C

Rationale: The highest priority nursing intervention in this scenario is to assess the fetal heart rate and the client's contraction pattern. The presence of a large amount of bright red vaginal bleeding in a woman at 36-weeks' gestation who is Rh negative raises concerns about the well-being of the fetus. Monitoring the fetal heart rate and contraction pattern will provide crucial information about fetal status and help determine the appropriate course of action to ensure the safety and health of both the mother and the baby.

5. 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?

• A. Assess the husband's feelings about his wife's decision to breastfeed their baby.
• B. Ask the client to describe why she was unsuccessful with breastfeeding her last child.
• C. Encourage the client to develop a positive attitude about breastfeeding to help ensure success.
• D. Provide assistance to the mother to begin breastfeeding as soon as possible after delivery.

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.
