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 newborn's parents tell the nurse that their baby is already trying to walk. How should the nurse respond?

• A. Encourage the parents to report this to the healthcare provider.
• B. Acknowledge the parents' observation.
• C. Schedule the newborn for further neurological testing.
• D. Explain the newborn’s normal stepping reflex.

Correct answer: D

Rationale: When parents report that their newborn is trying to walk, the nurse should understand that newborns exhibit a stepping reflex, which is a normal developmental response. Explaining this reflex to the parents helps them understand that it is a typical behavior seen in newborns rather than true attempts to walk. Encouraging the parents to report this to the healthcare provider (Choice A) may cause unnecessary concern since the stepping reflex is a normal part of newborn development. Acknowledging the parents' observation (Choice B) is a good communication strategy but providing education on the normal reflex is essential. Scheduling the newborn for further neurological testing (Choice C) is not indicated in this scenario as the stepping reflex is a typical finding in newborns.

3. The healthcare provider prescribes terbutaline (Brethine) for a client in preterm labor. Before initiating this prescription, it is most important for the LPN/LVN to assess the client for which condition?

• A. Gestational diabetes.
• B. Elevated blood pressure.
• C. Urinary tract infection.
• D. Swelling in lower extremities.

Correct answer: A

Rationale: The correct answer is A: Gestational diabetes. Terbutaline (Brethine) is known to cause hyperglycemia, so it is crucial to assess for gestational diabetes before administering it. Assessing for elevated blood pressure (choice B), urinary tract infection (choice C), or swelling in lower extremities (choice D) is not directly related to the potential side effect of terbutaline in causing hyperglycemia.

4. In caring for a 4-year-old boy recently diagnosed with Duchenne muscular dystrophy (DMD), which characteristic of the disease is most important for the nurse to focus on during the initial teaching?

• A. Lower legs become progressively weaker, causing a waddling, unsteady gait.
• B. Growth and development have been abnormal since birth.
• C. Muscular strength can be regained with physical exercise and therapy.
• D. Respiratory dysfunction and aspiration are prime concerns at this stage of the disease.

Correct answer: A

Rationale: In Duchenne muscular dystrophy, a key characteristic is the progressive weakness in the lower legs, leading to a waddling, unsteady gait. The nurse should focus on teaching about this aspect as it helps in understanding the disease's progression and managing the symptoms effectively.

5. A male infant with a 2-day history of fever and diarrhea is brought to the clinic by his mother, who tells the nurse that the child refuses to drink anything. The nurse determines that the child has a weak cry with no tears. Which intervention is most important to implement?

• A. Provide a bottle of electrolyte solution.
• B. Infuse normal saline intravenously.
• C. Administer an antipyretic rectally.
• D. Apply an external cooling blanket.

Correct answer: B

Rationale: Infusing normal saline intravenously is crucial to treat dehydration caused by fever and diarrhea. In this scenario, the infant's weak cry with no tears indicates severe dehydration, necessitating rapid fluid replacement via intravenous normal saline to restore fluid balance and prevent complications.
