A nurse is preparing to administer ondansetron 0.15 mg/kg IV to a child who is receiving chemotherapy and weighs 29.4 kg. Available is ondansetron 4 mg/2 mL solution. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2.2"]

To calculate the dose of ondansetron for a child who is receiving chemotherapy, the nurse needs to use the following formula:

Dose (mL) = (Dose ordered in mg / Dose available in mg) x Volume available in mL

In this case, the dose ordered in mg is 0.15 mg/kg x 29.4 kg, which equals 4.41 mg. The dose available in mg is 4 mg, and the volume available in mL is 2 mL. Therefore, the dose in mL is:

Dose (mL) = (4.41 mg / 4 mg) x 2 mL Dose (mL) = 2.205 mL

The nurse should round the answer to the nearest tenth, so the final answer is 2.2 mL. The nurse should administer 2.2 mL of ondansetron IV to the child who is receiving chemotherapy.

Correct Answer is A

Explanation

A. This is the correct instruction. Varicella (chickenpox) is highly contagious. The child should be kept away from others until all lesions are crusted over and no new lesions have formed for at least 24 hours. This typically indicates that the child is no longer contagious.

B. Applying calamine lotion can help alleviate itching and discomfort associated with the vesicles. This is a supportive measure but does not address the contagious nature of the disease.

C. Dressing the child in warm clothing is not specific to the management of varicella. It is important to keep the child comfortable, but this instruction does not address the
contagious period.

D. It is generally safe to give the child a bath during varicella. Warm baths with mild soap can help soothe itching. However, the child should be dried gently to avoid breaking open any vesicles.

A. Unexplained weight gain B. Night sweats C. Flushed skin D. Decreased body temperature
