A nurse is providing teaching for a 20-year-old adolescent who has syphilis. Which of the following statements should the nurse make?

Rationale:

A. Cutting and filing the child's fingernails frequently can help prevent further damage from scratching and reduce the risk of infection.

B. Using a mild detergent for the child's laundry can help minimize irritation to the skin.

C. Pimecrolimus cream is a topical immunomodulator that may be used for atopic dermatitis, but the thick layer application is not typically recommended for children due to safety concerns.

D. Informing the guardian that the child will experience occasional flare-ups of the condition helps manage expectations and prepares them for potential recurrence.

E. Atopic dermatitis is not typically contagious, so the statement that the child's condition is contagious when lesions are present is inaccurate.

F. Applying gloves to the child's hands can prevent scratching and further damage to the skin.

G. Applying emollients to the child's skin after bathing helps maintain skin hydration and barrier function, reducing the severity of atopic dermatitis symptoms.

Rationale:

First, we need to convert the child's weight from pounds to kilograms. We can do this by dividing 55 by 2.2, which gives us 25 kg.

Next, we need to multiply the dose of diphenhydramine by the child's weight to get the total amount of medication needed. We can do this by multiplying 1.25 mg/kg by 25 kg, which gives us 31.25 mg.

Finally, we need to divide the total amount of medication by the concentration of the solution to get the volume to be administered. We can do this by dividing 31.25 mg by 50 mg/mL, which gives us 0.625 mL.

To round the answer to the nearest tenth, we look at the hundredths place and see that it is 5 or more, so we round up the tenths place by one. Therefore, the nurse should administer 0.6 mL of diphenhydramine IV to the child.
