Question

the healthcare provider prescribes oral antifungal therapy for a client with onychomycosis. which information should the nurse tell the client? a single dose of the oral antifungal agent is usually sufficient to treat the infection. the infection is difficult to eradicate and requires prolonged therapy for 3 to 6 months. complete eradication is important because of the risk of a systemic infection. prolonged therapy provides no benefit and increases the risk of adverse effects.

Explanation:

1. Analyze Option A: Onychomycosis (fungal nail infection) typically requires more than a single dose of oral antifungal; single - dose is insufficient for this type of infection.
2. Analyze Option B: Onychomycosis is a chronic fungal infection of the nails. The slow - growing nature of nails and the difficulty of the fungus to be eradicated from the nail bed and matrix mean that treatment with oral antifungals usually takes 3 - 6 months.
3. Analyze Option C: Onychomycosis is a localized infection of the nails and does not typically pose a risk of systemic (whole - body) infection.
4. Analyze Option D: Prolonged therapy is necessary for onychomycosis to ensure eradication of the fungus. Stopping early can lead to recurrence, and the benefits of eradicating the infection outweigh the risks of adverse effects when monitored properly.

Answer:

B. The infection is difficult to eradicate and requires prolonged therapy for 3 to 6 months.
