What skin lesion is described as an elevated, thin-walled lesion containing clear fluid?

Choice A reason: A vesicle is a small, elevated, thin-walled lesion filled with clear fluid, typically less than 1 cm, seen in conditions like herpes or contact dermatitis. This matches the description perfectly, making it the correct choice for the lesion.

Choice B reason: A pustule is an elevated lesion filled with pus, not clear fluid, indicating infection or inflammation. The description specifies clear fluid, not purulent content, making pustule incorrect for the described skin lesion.

Choice C reason: A macule is a flat, non-elevated skin lesion with color change, like a freckle, not containing fluid. The description of an elevated, fluid-filled lesion does not match, making macule incorrect for this scenario.

Choice D reason: A nodule is a solid, elevated lesion deeper in the skin, not thin-walled or fluid-filled. The description of a clear fluid-filled, elevated lesion does not fit a nodule’s characteristics, making this choice incorrect.

Choice A reason: Peripheral neuropathy impairs sensation, increasing burn risk from hot water. Checking water temperature prevents thermal injuries, as patients may not feel extreme temperatures, protecting insensate feet from damage, making this the correct preventive action.

Choice B reason: An electromyogram (EMG) diagnoses neuropathy by assessing nerve function but does not prevent injury. It is a diagnostic tool, not a protective measure against physical harm, making this choice incorrect for injury prevention.

Choice C reason: Pain and inflammation medications manage neuropathy symptoms but do not prevent physical injuries like cuts or burns. They address discomfort, not sensory loss, which is the primary injury risk, making this choice incorrect.

Choice D reason: Open-toed sandals expose feet to injury, increasing risk in neuropathy due to poor sensation. Closed-toe shoes protect against trauma, making this choice incorrect for preventing injuries in peripheral neuropathy.
