Which term would describe a small blister containing clear fluid?

• A. Vesicle
• B. Papule
• C. Nodule
• D. Pustule

Answer: (A)

A vesicle is a small blister that contains clear fluid. It’s a raised skin lesion typically under 1 centimeter in diameter, distinguishing it from other lesions: a papule is a solid, raised bump with no fluid; a nodule is a larger, deeper solid mass; and a pustule contains pus and often looks creamy or yellow. Recognizing the fluid-filled nature and size helps identify vesicles, which commonly appear in conditions like herpes simplex or chickenpox.
