What are the right practices for self-care to be followed by a client with onychomycosis of the foot?

Correct Answer: C

Rationale: The correct answer is C: Avoid walking barefoot. This practice helps prevent spreading the fungal infection to other areas and reduces the risk of reinfection. Walking barefoot in public places can expose the affected foot to more fungi. Explanation: 1. Walking barefoot increases the risk of spreading the infection. 2. Shoes act as a barrier to protect the affected foot. 3. Avoiding barefoot walking reduces the chances of reinfection. 4. It is a key preventive measure in managing onychomycosis. Summary: A: Incorrect. Antifungal medications for onychomycosis need to be taken for several weeks to months, not just 5 to 10 days. B: Incorrect. Changing footwear alone does not target the root cause of the infection. D: Incorrect. Keeping the feet moist can exacerbate the fungal growth.

Correct Answer: D

Rationale: The correct answer is D because topical hydrocortisone does not block photosensitivity caused by drugs. Topical hydrocortisone is a corticosteroid used to reduce inflammation in the skin, not to block photosensitivity. A is incorrect because obesity can actually lead to decreased sweating, not increased sweating. B is incorrect because benzophenones primarily protect against UVB rays, not both UVA and UVB. C is incorrect because while UVA rays do contribute to skin cancer, UVB rays are considered the primary cause.

Correct Answer: D

Rationale: The correct answer is D: Plantar wart. Papillomavirus infection on the skin is commonly known as a wart. Plantar warts specifically appear on the soles of the feet. Warts are caused by the human papillomavirus (HPV). Furuncle (A) and carbuncle (B) are skin abscesses caused by bacterial infections. Erysipelas (C) is a bacterial skin infection causing redness and swelling. Plantar wart is the most appropriate choice due to its association with papillomavirus and its specific location on the skin.

Correct Answer: A

Rationale: The correct answer is A: Cool tap water dressings. Cool tap water helps to soothe inflamed and pruritic skin by reducing itching and inflammation. It also provides a cooling effect, which can help alleviate discomfort. B: Cool acetic acid dressings may be too harsh and irritating for inflamed skin. C: Warm sterile saline dressings may further irritate the skin and exacerbate inflammation. D: Warm potassium permanganate dressings can be too strong and may cause further irritation and drying of the skin.

Correct Answer: B

Rationale: The correct answer is B: Increased sweating. This is because high-dose corticosteroids commonly cause skin thinning, making it difficult for the skin to retain moisture and leading to decreased sweating. Alopecia (A), dry, coarse, brittle hair (C), and impaired wound healing (D) are all potential dermatologic manifestations of long-term corticosteroid use due to their effects on skin health and healing processes.
