When discussing care of an infant with congenital hypothyroidism, you would stress that the infant will need:
vitamin K administration until school age.
administration of vitamin C until after growth is complete.
administration of levothyroxine for a lifetime.
an increased intake of calcium beginning in infancy.
The Correct Answer is C
A. Vitamin K is routinely given at birth to prevent hemorrhagic disease but is not required long-term for congenital hypothyroidism.
B. Vitamin C supplementation is not specifically indicated for congenital hypothyroidism.
C. Levothyroxine is the standard treatment for congenital hypothyroidism. Early and consistent administration is crucial for normal growth and neurodevelopment. Most infants will require lifelong therapy, with periodic monitoring and dosage adjustments based on growth and thyroid function tests.
D. While calcium is important for overall growth, congenital hypothyroidism does not specifically require increased calcium intake beyond standard nutritional recommendations.

Correct Answer is ["A","C","D"]
Explanation
A. Calcium gluconate is the antidote for magnesium sulfate toxicity and must be immediately available when administering magnesium sulfate for seizure prophylaxis in severe gestational hypertension.
B. Respiratory status should be assessed frequently (ideally every 15–30 minutes during magnesium infusion) because magnesium sulfate can cause respiratory depression; assessing only every 4 hours is inadequate.
C. A dark, quiet environment helps reduce stimulation, which can minimize seizure risk in clients with severe hypertension or preeclampsia.
D. Magnesium sulfate IV is commonly prescribed to prevent eclampsia in clients with severe gestational hypertension.
E. Neurologic status should be evaluated frequently (e.g., every 1–2 hours) rather than every 8 hours to monitor for early signs of worsening preeclampsia or magnesium toxicity.
Correct Answer is D
Explanation
A. A negative test refers to a contraction stress test (CST), not an NST, and indicates no late decelerations with contractions. This is not relevant here.
B. A positive test in a CST indicates repetitive late decelerations, which is not applicable to NST interpretation.
C. A reactive NST requires two or more accelerations of at least 15 bpm lasting 15 seconds within a 20-minute period for a fetus ≥32 weeks. Minimal variability with no accelerations does not meet criteria for reactivity.
D. A nonreactive NST occurs when the fetal heart rate fails to demonstrate the required accelerations over a 40-minute period or exhibits minimal variability, indicating possible fetal hypoxia or sleep state. The presence of brief decelerations does not compensate for the lack of accelerations. The nurse should notify the provider for further evaluation, which may include additional testing or interventions.
