Appeared in: NORCET -4

Explanation

The image displays a classic annular (ring-shaped) lesion with an active, erythematous, and scaly border, along with central clearing.
This presentation is characteristic of Tinea corporis, a fungal infection affecting the glabrous (smooth, non-hairy) skin of the body, such as the trunk and limbs.
The term 'ringworm' is a misnomer, as the infection is caused by a fungus (dermatophyte), not a worm.
The infection spreads centrifugally (outward from the center) while the central area begins to heal, creating the typical ring-like appearance.

Option A: This is incorrect because Tinea pedis, also known as athlete's foot, is a fungal infection that specifically affects the feet, causing scaling and maceration, typically between the toes. The lesion in the image is on the skin of the body, not the foot.
Option C: This is incorrect because Tinea capitis is a fungal infection of the scalp. It typically presents with patches of hair loss (alopecia), scaling, and sometimes inflammatory swellings called kerions. The lesion in the image is on the skin, not the scalp.
Option D: This is incorrect as Tinea unguium, also known as onychomycosis, is a fungal infection of the nails. It causes nails to become thickened, brittle, discolored (yellowish or opaque), and crumbly. The image clearly shows a skin lesion, not an affected nail.

Clinical Relevance

Nursing practice connection: Use the key finding related to Identification of dermatophyte infections based on clinical presentation to guide bedside assessment, documentation, and the next nursing action.
Nurses must be able to differentiate various skin lesions to provide appropriate patient education on hygiene, treatment adherence (e.g., completing the full course of antifungal medication), and preventing transmission to others.
A key nursing intervention is to advise patients to keep the affected area clean and dry, avoid sharing personal items like towels and clothing, and wear loose-fitting clothes to reduce moisture and friction.
What if? If the lesion were on the scalp with associated hair loss, the diagnosis would shift to Tinea capitis, which often requires systemic (oral) antifungal therapy in addition to topical treatments, as topical therapy alone is usually ineffective.

How to Approach the Question

First, carefully examine the image provided. Note the key features of the lesion: its shape, color, border, texture, and location on the body.
In this image, observe the circular (annular) shape, the red and scaly raised border, and the clearer area in the center.
Next, evaluate the given options, which are all types of 'Tinea' (fungal) infections named after the body part they affect.
Correlate the location and appearance of the lesion in the image with the definitions of each type of Tinea infection.
Tinea corporis affects the body ('corpus'), and its classic presentation matches the image. Tinea pedis (feet), capitis (scalp), and unguium (nails) affect different body parts and have different appearances.
Select the option that best matches the visual evidence.
