Question 5 of 5
The pediatrician has diagnosed tinea capitis in an 8-year-old girl and has placed her on oral griseofulvin. The nurse should emphasize which of these instructions to the mother and/or child?
Correct Answer: D
Rationale: Giving the drug with or after meals may allay gastrointestinal discomfort. Giving the drug with a fatty meal (ice cream or milk) increases absorption rate. Griseofulvin may alter taste sensations and thereby decrease the appetite. Monitoring of food intake is important, and inadequate nutrient intake should be reported to the physician. The child may experience symptomatic relief after 48-96 hours of therapy. It is important to stress continuing the drug therapy to prevent relapse (usually about 6 weeks). The incidence of side effects is low; however, headaches are common. Nausea, vomiting, diarrhea, and anorexia may occur. Dizziness, although uncommon, should be reported to the physician.
