Question 17-hydroxylase deficiency--treatment for increased body hair?

Dear all,

Did a question on First Aid Q n A Step 2 CK, and had a really tough question which I did not understand :

13 y/o boy, brought to pediatrician because of increasing body hair. Severeal months ago, he was dx with 17-hydroxylase deficiency, and treated with hydrocortisone. PE : overweight boy, moderate amout of chest and genital hair, and some facial hair growth. Which is the best treatment plan :

a) add cosyntropin
b) add dexamethasone
c) add spironolactone
d) increase hydrocortisone
e) keep current dose of hydrocortisone

What would your answer be and why?

17-hydroxylase deficiency, there is increase in aldosterone (hypertention and hypoklemia ) so we
and decrease in cortisol and sex hormone
so the answer is d) increase hydrocortisone
