A nurse is preparing to administer furosemide 1 mg/kg IV bolus to a preschooler who weighs 36 lb. Available is furosemide injection 10 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.6"]

To calculate this, first convert the preschooler's weight from pounds to kilograms: 36 lb * (1 kg / 2.2 lb) = 16.36 kg.

Then, calculate the dose of furosemide in mg: 1 mg/kg * 16.36 kg = 16.36 mg.

Finally, divide the dose in mg by the concentration of the furosemide injection to find the volume to administer: 16.36 mg / (10 mg/mL) = 1.636 mL/dose, which rounds to 1.6 mL when rounded to the nearest tenth.

Correct Answer is ["0.5"]

Explanation

Here's the detailed explanation: First, we need to convert the child's weight from pounds (lb) to kilograms (kg) since

the prescribed dose is in mg/kg/day.

There are approximately 2.2 lb in 1 kg, so the child's weight in kg is 55 lb / 2.2 = 25 kg. Next, we need to calculate the total daily dose of methimazole for the child.

The prescribed dose is 0.3 mg/kg/day, so the total daily dose is 25 kg * 0.3 mg/kg/day = 7.5 mg/day.

Since the medication is to be divided into equal doses every 8 hours, we need to divide the total daily dose by 3 to get the dose per administration: 7.5 mg/day / 3 = 2.5 mg per dose.

Finally, since each tablet contains 5 mg of methimazole, we need to divide the dose per administration by the amount of medication per tablet: 2.5 mg per dose / 5 mg per tablet = 0.5 tablets per dose.

Correct Answer is ["0.019"]

Explanation

19,000 mcg of haloperidol is equivalent to 0.019 g.

To calculate this, use the conversion factor that 1 g is equivalent to 1,000,000 mcg. So, 19,000 mcg * (1 g / 1,000,000 mcg) = 0.019 g.
