A nurse is providing teaching 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 once the lesions have crusted over."
"Your child can return to school once the fever has subsided."
"Your child can return to school 24 hours after beginning antibiotics."
"Your child can return to school after a negative titer result."
The Correct Answer is A
A: Varicella (chickenpox) is contagious until all lesions have crusted over. The crusting of the lesions indicates that the virus is no longer active and transmissible.
B: Although a decrease in fever suggests improvement, it does not signify that the child is no longer contagious. Children with varicella are still contagious until all blisters have crusted over.
C: Antibiotics are not effective against viral infections like varicella. Therefore, this statement is inaccurate as it implies antibiotics are part of the treatment for varicella.
D: Varicella is diagnosed clinically and through symptoms rather than titer results. Titer testing is not a standard criterion for determining when a child can return to school.

Correct Answer is A
Explanation
To calculate the IV infusion rate for dopamine hydrochloride, we first need to convert the dose from micrograms per kilogram per minute (mcg/kg/min) to milligrams per hour (mg/hr). The patient weighs 80 kg and the prescribed dose is 4 mcg/kg/min.
First, calculate the dose in mcg/hr: 4 mcg/kg/min x 80 kg x 60 min/hr = 19200 mcg/hr.
Next, convert mcg to mg: 19200 mcg/hr / 1000 mcg/mg = 19.2 mg/hr.
We have an 800 mg dopamine hydrochloride solution in a 250 mL bag. To find out how many mL/hr to administer, we use the following proportion:
(800 mg / 250 mL) = (19.2 mg / X mL).
Solving for X gives us X = (19.2 mg * 250 mL) / 800 mg, which equals 6 mL/hr.
Therefore, the nurse should set the IV infusion pump to deliver 6 mL/hr.
Correct Answer is B
Explanation
A. This advice may lead to inadequate emptying of the breasts and imbalance in milk production, potentially affecting milk supply and infant feeding.
B. Encouraging feeding on demand promotes effective breastfeeding by allowing the infant to feed when hungry, which helps establish and maintain milk supply. This approach supports infant cues and promotes successful breastfeeding.
C. Strict time limits on feeding can interfere with effective breastfeeding and hinder milk transfer, potentially leading to inadequate nutrition for the infant.
D. Water supplementation is unnecessary for breastfed infants and can interfere with breastfeeding by reducing infant appetite for breast milk.
