A newborn is admitted to the pediatric unit to rule out congenital hypothyroidism. Which of the following findings would the nurse expect if this diagnosis is confirmed?

A.

Bradycardia, constipation, and hypotonia

B.

Elevated serum T3 and T4

C.

Tachycardia, diarrhea, and tremors

D.

Decreased thyroid stimulating hormone (TSH)

Answer and Explanation

The Correct Answer is A

Rationale:


A. Bradycardia, constipation, and hypotonia are common symptoms associated with congenital hypothyroidism due to the reduced metabolism that results from decreased thyroid hormone levels.

 

B. Elevated serum T3 and T4 would not be expected in congenital hypothyroidism; these levels are typically low.

 

C. Tachycardia, diarrhea, and tremors are more indicative of hyperthyroidism, not hypothyroidism.

 

D. In congenital hypothyroidism, the thyroid-stimulating hormone (TSH) is typically elevated as the body attempts to stimulate the thyroid gland to produce more hormones.

Correct Answer is B

Explanation

Rationale:

A. Symptoms of Epstein-Barr virus, also known as mononucleosis, can last for several weeks to months, not just 7-10 days.

B. Epstein-Barr virus is spread through saliva, so avoiding sharing drinks or utensils helps prevent transmission.

C. Bed rest is recommended, but it is not the only measure needed; monitoring and managing symptoms is also important.

D. Epstein-Barr virus is a viral infection, and antibiotics are not effective in treating viral illnesses.

Correct Answer is C

Explanation

Rationale:

A. Neurologic function is not typically affected by nephrotic syndrome, so improvement in this area is not an indicator of recovery.

B. Weight gain might indicate fluid retention rather than recovery in nephrotic syndrome.

C. The absence of protein in the urine indicates that the kidneys are functioning properly and that the syndrome is resolving. Proteinuria is a hallmark of nephrotic syndrome, so its resolution is a key sign of recovery.

D. A negative gram stain is more relevant to infections, not nephrotic syndrome.
