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.

A. Seal soft toys in a plastic bag for 14 days. B. Soak hairbrushes in boiling water for 10 min. C. Apply bactericidal ointment to lesions. D. Administer acyclovir PO two times per day.

Correct Answer is C

Explanation

A. There is no need to seal soft toys in a plastic bag for 14 days as impetigo is not typically spread through inanimate objects. However, it is important to discourage the child from scratching the lesions to prevent further spread.

B. Soaking hairbrushes in boiling water is not necessary for the management of impetigo.
Impetigo is caused by bacteria, not lice, so boiling hairbrushes is not a standard recommendation for this condition.

C. This is the correct instruction. Applying a bactericidal ointment (e.g., mupirocin) to the impetigo lesions is a common treatment approach. This helps to eliminate the bacteria causing the infection and promote healing.

D. Administering acyclovir is not indicated for impetigo. Acyclovir is an antiviral
medication used to treat viral infections, such as herpes simplex virus. Impetigo is caused by bacterial infection, not a virus.
