Which medication is started at 0.2 mg PO QHS for nocturnal enuresis in children?

Dexamethasone
Miralax
Desmopressin
Racemic epinephrine

The correct answer is: Desmopressin

Desmopressin is the correct answer for this question. Desmopressin is a synthetic analog of vasopressin, which is an antidiuretic hormone that helps reduce urine production. It is commonly used to treat nocturnal enuresis (bedwetting) in children. The recommended starting dose for treating nocturnal enuresis in children is 0.2 mg orally at bedtime (PO QHS). Desmopressin works by reducing the amount of urine produced by the kidneys overnight, thus helping to prevent bedwetting episodes. On the other hand: - A. Dexamethasone is a corticosteroid used for its anti-inflammatory and immunosuppressant effects. - B. Miralax is a laxative used to treat constipation by increasing the water content and bulk of the stool. - D. Racemic epinephrine is a bronchodilator used to treat respiratory conditions like croup or asthma.
