Rationale: Calcipotriene (Dovonex), an analogue of vitamin D3, is indicated for mild to moderate psoriasis. Responses are equal to those achieved with medium-potency topical glucocorticoids. The most common adverse effect is local irritation. Unlike glucocorticoids, calcipotriene does not cause thinning of the skin. At high doses, calcipotriene has caused hypercalcemia. Hyperkalemia is not a side effect.
Answer to Question 2

Rationale: The classic symptoms of children with brain tumors are headache and morning vom-iting related to the child getting out of bed. Headaches worsen on arising but improve during the day. Fatigue may occur but is a vague symptom. Visual changes may occur, including nystagmus, diplopia, and strabismus, but these signs are not the hallmark symptoms with a brain tumor.
