Potential Nursing Diagnoses

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

Implementation

  • Consult health care professional for proper cleansing technique before applying medication.
  • Vaginal: Applicators are supplied for vaginal administration.

Patient/Family Teaching

  • Instruct patient to apply medication as directed for full course of therapy, even if feeling better. Therapy should be continued during menstrual period.
    • Advise patient to avoid using tampons or douches while using this product.
    • Instruct patient on proper use of vaginal applicator. Medication should be inserted high into the vagina at bedtime. Instruct patient to remain recumbent for at least 30 min after insertion. Advise use of sanitary napkins to prevent staining of clothing or bedding.
    • Advise patient to consult health care professional regarding intercourse during therapy. Vaginal medication may cause minor skin irritation in sexual partner. Advise patient to refrain from sexual contact during therapy. Advise patient that this medication may weaken latex or rubber contraceptive products. Another method of contraception should be used during treatment.
    • Advise patient to report to health care professional increased skin irritation or lack of response to therapy. A second course may be necessary if symptoms persist.
    • Advise patient to thoroughly clean the applicator after each use.
    • Advise patient to notify health care professional if signs and symptoms of anaphylaxis (hives, shortness of breath, facial swelling) or rash occurs.

Evaluation/Desired Outcomes

  • Decrease in skin irritation and vaginal discomfort. Therapeutic response is usually seen after 1 wk. Diagnosis should be reconfirmed with smears or cultures before a second course of therapy to rule out other pathogens associated with vulvovaginitis. Recurrent vaginal infections may be a sign of systemic illness.
