A nurse is providing care to a parent of a child who has varicella. Which of the following statements should the nurse include in the teaching?
“Your child can return to school after a negative titer result.”
“Your child can return to school once the fever has subsided.”
“Your child can return to school once the lesions have crusted over.”
“Your child can return to school 24 hours after beginning antibiotics.”
The Correct Answer is C
A. A negative titer is used to determine immunity, not the infectious period. It does not indicate when the child is no longer contagious.
B. Fever may subside before the lesions have fully crusted, so relying on fever alone is insufficient to prevent transmission.
C. Varicella (chickenpox) is highly contagious. Children are considered infectious from 1–2 days before the rash appears until all lesions have crusted over. Returning to school before crusting can spread the virus to others.
D. Antibiotics do not treat viral infections like varicella. The child may still be contagious even after starting antibiotics.

Correct Answer is C
Explanation
A. Decreased BUN is not expected in preeclampsia. Instead, renal impairment can cause BUN and creatinine to increase due to decreased kidney perfusion.
B. Serum uric acid typically increases in preeclampsia as a result of reduced renal clearance; a decreased value would not be expected.
C. Increased protein in urine (proteinuria) is a hallmark sign of preeclampsia, reflecting glomerular damage and impaired renal function. It is used diagnostically in conjunction with elevated blood pressure and edema.
D. Increased platelet count is incorrect because preeclampsia often causes thrombocytopenia due to platelet aggregation and consumption within damaged vessels.
