Answer to Question 1

Ans: C
All children with severe burns should receive 100 oxygen via a nonrebreather mask or bag-valve-mask ventilation. A nasal cannula provides only low oxygen concentrations (22 to 44); a Venturi mask provides only 24 to 50 oxygen concentrations. An oxygen hood is used for infants only.

Answer to Question 2

Ans: B
Urticaria is a type I hypersensitivity reaction caused by an immunologically mediated antigenantibody response of histamine release from the mast cells. Vasodilation and increased vascular permeability result, leading to erythema and then wheals. The rash is pruritic and blanches with pressure.
