Which of the following treatment measures should be implemented for a child with leukemia who has been exposed to the chickenpox?
A. No treatment is indicated.
B. Acyclovir (Zovirax) should be started on exposure
C. Varicella-zoster immunoglobulin (VZIG) should be given with the evidence of disease
D. VZIG should be given within 72 hours of exposure.
Answer: D
Explanation: Varicella is a lethal organism to a child with leukemia. VZIG, given within 72 hours, may favorably alter the course of the disease. Giving the vaccine at the onset of symptoms wouldn't likely decrease the severity of the illness. Acyclovir may be given if the child develops the disease but not if the child has been exposed.
