What is the recommended time for a child with varicella to return to school?
After all the blisters have crusted over
After receiving the varicella vaccine
After completing one week of antiviral medication
As soon as the rash appears
The Correct Answer is A
A. A child with varicella (chickenpox) should return to school only after all the blisters have crusted over, indicating that the infectious stage has passed and they are no longer contagious.
B. Receiving the varicella vaccine does not apply to children who already have the infection; vaccination is preventive, not a treatment for those already infected.
C. Completing one week of antiviral medication is not a sufficient criterion for returning to school, as the child may still be contagious until all lesions are crusted.
D. Returning to school as soon as the rash appears is not safe, as the child is highly contagious during the initial rash stage and until all lesions have crusted.

Correct Answer is ["B","C","E"]
Explanation
A. Cyanosis of the lips and tongue is not a typical finding in coarctation of the aorta; rather, it is more associated with cyanotic congenital heart defects.
B. Weak or absent femoral pulses are expected due to reduced blood flow to the lower body, as the coarctation typically occurs distal to the left subclavian artery.
C. Bounding pulses in the upper extremities are common because the blood flow to the upper body is increased, leading to stronger pulses.
D. High blood pressure in the lower extremities is not typical; instead, there is often lower blood pressure in the lower body due to the obstruction.
E. Poor feeding and irritability are common symptoms in infants with heart conditions, as they may be in distress or not getting enough blood flow to meet their metabolic needs.
