Correct answer
C
Rationale
A hallmark sign of pemphigus vulgaris is Nikolsky's sign, which occurs when the epidermis can be rubbed off by slight friction or injury. Other characteristics include flaccid bullae that rupture easily and emit a foul-smelling drainage, leaving crusted, denuded skin. The lesions are common on the face, back, chest, and umbilicus. Even slight pressure on an intact blister may cause spread to adjacent skin. Turner's sign refers to a grayish discoloration of the flanks and is seen in clients with acute pancreatitis. Chvostek's sign, seen in tetany, is a spasm of the facial muscles elicited by tapping the facial nerve in the region of the parotid gland. Trousseau's sign is a sign for tetany, in which carpal spasm can be elicited by compressing the upper arm with a blood pressure cuff inflated above the systolic pressure and causing ischemia to the nerves distally.
