A 1 wk old infant is brought to the ER due to the vomiting and poor feeding. The prenatal and birth histories are unremarkable. The infants pulse is 140/min, temp 37 C (98.7 F) and capillary refill is 2 seconds. He has sunken eyes and depressed anterior fontanel and dry mucus membranes, skin elasticity is reduced. Heart and lungs are clear. There is no abdominal mass. Genital examination shows enlarged clitoris and fusion of the labioscrotal folds. The initial lab work up reveals the following :
Na---------- 128 mEq/L
K ----------- 5.8 mEq/L
BUN -------- 25 mg/dL
If this pt's karyotype is 46 XX, which of the following is most likely to be increased in this pt's serum ?
A- 17-alpha hydroxyprogesterone
B- 18-hydroxycorticosterone
C- 11-deoxycorticosterone
D- 11-deoxycortisole
