Nursing implications

Nursing assessment

  • Inspect involved areas of skin and mucous membranes before and frequently during therapy. Increased skin irritation may indicate need to discontinue medication.

Potential Nursing Diagnoses

Risk for impaired skin integrity (Indications)
Risk for infection (Indications)

Implementation

  • Consult health care professional for proper cleansing technique before applying medication.
  • Topical: Apply small amount to cover affected area completely. Avoid the use of occlusive wrappings or dressings unless directed by health care professional.

Patient/Family Teaching

  • Instruct patient to apply medication as directed for full course of therapy, even if feeling better. Emphasize the importance of avoiding the eyes.
  • Caution patient that some products may stain fabric, skin, or hair. Check label information. Fabrics stained from cream can usually be cleaned by handwashing with soap and warm water.
  • Patients with athlete’s foot should be taught to wear well-fitting, ventilated shoes, to wash affected areas thoroughly, and to change shoes and socks at least once a day.
  • Advise patient to report increased skin irritation or lack of response to therapy to health care professional.

Evaluation/Desired Outcomes

  • Decrease in skin irritation and resolution of infection. Early relief of symptoms may be seen in 2–3 days. For tinea cruris and tinea corporis, 2 wk are needed, and for tinea pedis, therapeutic response may take 4 wk. Recurrent fungal infections may be a sign of systemic illness.
