The nurse caring for a child diagnosed with rubeola (measles) notes that the pediatrician has documented the presence of Koplik's spots. On the basis of this documentation, which observation is expected?

A. "Range-of-motion exercises must be performed every day."
Explanation: While range-of-motion exercises are important for maintaining joint flexibility in juvenile idiopathic arthritis, it is not advisable to perform these exercises during painful exacerbations. The frequency and intensity of exercises may need to be adjusted based on the child's current condition.
B. "Administer additional pain medication before performing range-of-motion exercises."
Explanation: While pain management is important in the care of a child with juvenile idiopathic arthritis, relying solely on pain medication before exercises may not be the most effective approach. Isometric exercises that are less likely to cause pain can be a better option during exacerbations.
C. "Have the child perform simple isometric exercises during this time."
Explanation:
During a painful exacerbation of juvenile idiopathic arthritis, it is important to maintain joint flexibility and prevent joint contractures. Simple isometric exercises that do not involve joint movement can help in maintaining muscle strength and joint flexibility without exacerbating pain. Range-of-motion exercises may be too painful during an exacerbation, but isometric exercises can be less painful and still beneficial.
D. "Avoid all exercise during painful periods."
Explanation: Complete avoidance of exercise during painful periods is not recommended. Maintaining joint flexibility and muscle strength is important for managing juvenile idiopathic arthritis. However, the type and intensity of exercises should be adjusted based on the child's pain level during exacerbations.

The Parkland formula is commonly used to calculate the fluid requirements for burn resuscitation. The formula is:

Fluid requirement (in mL)=TBSA×Weight (in kg)×Fluid volume (in mL/kg)

For burn patients, the recommended fluid volume is typically 4 mL/kg for each percent of TBSA burned.

Let's calculate the fluid requirement for the given case:

Fluid requirement=40%×22 lbs×4 mL/kg

First, convert the weight from pounds to kilograms:

Weight (in kg)= Weight (in lbs)/2.2

Weight (in kg)=22 lbs/2.2≈10 kg

Now, calculate the fluid requirement:

Fluid requirement=40% x 10 kg × 4 mL/kg

Fluid requirement=1600mL(totalfluidover24hours)

Fluid for the first 8 hours:

1600/2=800ml

Thus, the child will receive 800 mL of fluid in the first 8 hours after the burn injury.
