Answer to Question 1

ANS: C
A third-degree, or full-thickness, burn is a serious injury that involves the entire epidermis and dermis and extends into the subcutaneous tissues. Erythema and pain are characteristic of a first-degree, or superficial, burn. Erythema with blister formation is characteristic of a second-degree, or partial-thickness, burn. A fourth-degree burn is a full-thickness burn that also involves underlying structures such as muscle, fascia, and bone.

Answer to Question 2

ANS: B
Evidence of an inhalation injury is burns of the face and lips, singed nasal hairs, and laryngeal edema. Clinical manifestation may be delayed for up to 24 hours. Chemical burns, electrical burns, and those associated with hot-water scalds would not cause singed nasal hair.
