Which instruction should a nurse give to a client who is prescribed clotrimazole vaginal tablets for treatment of candidiasis?

A. Vaginal clotrimazole tablets are inserted deep into the vagina, and bedtime administration is recommended. Lying down helps retain the medication, reduces leakage, and allows for maximum contact with the vaginal mucosa during sleep, increasing the effectiveness of treatment. B. Clotrimazole vaginal tablets are intended for internal vaginal use, not just external lesions. External application is used with creams for vulvar irritation, but vaginal tablets must be inserted into the vagina. C. Using tampons during therapy can interfere with absorption of the medication and reduce its effectiveness. Clients should avoid tampons and instead use panty liners if needed for discharge. D. The full course of therapy should be completed as prescribed, even if symptoms improve before the end of treatment. Stopping early may result in incomplete eradication of the infection and increase the risk of recurrence.
