When assessing an infant suspected of having the most common form of congenital adrenal hyperplasia, the nurse practitioner should expect to observe:
genital ambiguity.
hyperglycemia.
hypokalemia.
Hyponatremia
The Correct Answer is A
Rationale:
A. The most common form of congenital adrenal hyperplasia (CAH) is 21-hydroxylase deficiency. In female infants, this often results in genital ambiguity due to excess androgen production in utero, leading to virilization.
B. Hyperglycemia is not typical in CAH; infants may instead present with hypoglycemia due to salt-wasting crises in severe forms.
C. Hypokalemia is uncommon; CAH typically presents with hyperkalemia in salt-wasting forms due to aldosterone deficiency.
D. Hyponatremia can occur in salt-wasting CAH, but the most immediately observable sign in a newborn is genital ambiguity in affected females.
