Which skin condition would cause a nurse to suspect chickenpox?

D
A vesicle is a circumscribed elevation of skin filled with serous fluid, smaller than 1 cm (e.g., herpes simplex, chickenpox). A wheal is an irregularly shaped, elevated area of superficial localized edema that varies in size (e.g., hive, mosquito bite); it is not characteristic of chickenpox. A nodule is an elevated solid mass, deeper and firmer than a papule, 1 to 2 cm (e.g., wart), and not characteristic of chickenpox. A pustule is a circumscribed elevation of skin similar to a vesicle but filled with pus; it varies in size (e.g., acne, staphylococcal infection) and is not characteristic of chickenpox.
