## 문제

A nurse is caring for a patient with a confirmed Candida albicans skin infection in the groin area. Which nursing intervention should be the priority?

## 보기

1. Apply a thick layer of petroleum jelly to the affected area twice daily
2. Keep the affected area clean and dry, and apply antifungal medication as prescribed **✔ 정답**
3. Cover the infected area with an occlusive dressing to prevent spread
4. Encourage the patient to take hot baths to reduce itching and discomfort

**정답: 2**

## 해설

Candida albicans thrives in warm, moist environments, so keeping the area clean and dry while applying antifungal medication is the priority to eliminate infection. Other options like petroleum jelly or occlusive dressings trap moisture and worsen fungal growth.

## 심화 해설

Correct Answer: 2

Understanding the Pathophysiology

The priority intervention for a Candida albicans skin infection centers on disrupting the environmental conditions that promote fungal overgrowth. Candida species are commensals that transition to a pathogenic state when host-microbe homeostasis is disrupted [1]. A critical factor in this transition is moisture. The fungus thrives in warm, moist, macerated skin folds, such as the groin. Keeping the area clean and dry directly counteracts this by removing organic debris that can act as a nutrient source and by reducing the moisture essential for fungal proliferation. The application of a prescribed antifungal medication then directly targets the pathogen, working synergistically with the hygiene measures to resolve the infection.

Why Other Options Are Incorrect

- Option 1: Applying petroleum jelly creates a thick, occlusive barrier. This traps moisture and heat against the skin, which will worsen the infection by maintaining the ideal environment for Candida growth.

- Option 3: An occlusive dressing functions similarly to petroleum jelly. It prevents air circulation and traps moisture, creating a greenhouse effect that promotes fungal overgrowth and can lead to skin maceration and secondary bacterial infection.

- Option 4: Hot baths can increase local vasodilation and moisture. The heat can exacerbate itching and inflammation, while prolonged soaking macerates the skin, compromising its barrier function and providing a more favorable environment for the fungus.

Clinical Reasoning and NCLEX Focus

This question tests the fundamental nursing principle of managing superficial fungal infections by altering the environment. The core of the intervention is to make the skin inhospitable to the pathogen. Candida’s ability to adhere to tissues and invade epithelium makes it crucial to not only apply an antifungal agent but also to mechanically and environmentally disrupt its foothold [1]. The priority is always the least invasive, most effective combination of hygiene and topical therapy before considering more aggressive measures. The nurse must recognize that any intervention that increases moisture, such as occlusive dressings or emollients, is contraindicated in this clinical scenario.References (research sources)

## 임상 시나리오

Candida Skin Infection ManagementPriority Nursing Interventions for Intertriginous Areas
The primary goal is to disrupt the moisture and warmth that drive fungal overgrowth. Keep the groin area meticulously clean and dry by gently cleansing and patting dry, not rubbing.

Apply a topical antifungal (e.g., clotrimazole, nystatin) exactly as prescribed, typically in a thin layer to the affected area. Continue use for the full prescribed duration, even if symptoms improve, to prevent recurrence.

CautionNever use occlusive barriers like petroleum jelly or airtight dressings, as they trap moisture and heat, worsening the infection. Avoid hot baths or prolonged soaking, which cause skin maceration.

## 핵심 개념

- **Candida albicans** — A commensal yeast that becomes pathogenic in warm, moist, macerated skin folds, causing cutaneous candidiasis.
- **Skin Maceration** — Softening and breakdown of skin from prolonged exposure to moisture, which compromises the skin barrier and promotes infection.
- **Occlusive Dressing** — A dressing that seals the wound from air and moisture, contraindicated in fungal infections as it traps moisture and heat.
- **Antifungal Medication** — Topical agents such as azoles or nystatin that target the fungal cell membrane to eradicate Candida infection.
