A primary healthcare provider prescribes 25 mg per kilogram per dose of carmustine to a child with Hodgkin disease. A nurse finds that the child weighs 99 lbs. What dosage of medication should the nurse administer to the child daily?

1125 mg/dose

1237.5 mg/dose

2475 mg/dose

6544.5 mg/dose

Answer and Explanation

The Correct Answer is A

First, we need to convert the weight of the child from pounds to kilograms:. 99 lb / 2.2046 = 44.91 kg (rounded to two decimal places).

Next, we can calculate the dose of carmustine:. 25 mg/kg x 44.91 kg = 1,122.75 mg.

We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 1,122.75 mg seems reasonable for a child with Hodgkin disease..

Since the medication is prescribed daily, the nurse should administer the calculated dose of 1,122.75 mg of carmustine to the child every day.

Correct Answer is B

Explanation

To calculate the dose of dobutamine in mg/hr, we need to convert the patient's weight from pounds (lb) to kilograms (kg) and then use the ordered dose of 10 mcg/kg/min.

1 lb = 0.453592 kg (rounded to 6 decimal places) Patient's weight in kg = 110 lb x 0.453592 kg/lb

Patient's weight in kg = 49.89512 kg (rounded to 5 decimal places)

Now we can calculate the dose of dobutamine in mg/hr using the following formula:

Dose (in mg/hr) = Weight (in kg) x Dose (in mcg/kg/min) x 60 (to convert minutes to hours) / 1000 (to convert mcg to mg)

Dose (in mg/hr) = 49.89512 kg x 10 mcg/kg/min x 60 / 1000

Dose (in mg/hr) = 29.937072 mg/hr (rounded to 3 decimal places)

Therefore, the patient should receive a dose of approximately 29.9 mg/hr of dobutamine.

A. 0.1 tablets B. 0.5 tablets C. 1 tablet D. 3 tablets

Correct Answer is C

Explanation

The Tylenol 3 medication contains codeine 30 mg and acetaminophen (APAP) 300 mg per tablet.

The physician has ordered Tylenol 3 30 mg every 4-6 hours as needed for pain. Therefore, the nurse should administer 1 tablet (containing 30 mg of codeine and 300 mg of APAP) every 4-6 hours as needed for pain..

It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.
