A nurse is preparing to administer haloperidol 19,000 mcg PO to a school-age child who has Tourete's syndrome. The nurse should recognize that this is equivalent to how many g? (Round the answer to the nearest thousandth. Use a leading zero if applicable. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.019"]

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.

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 ["1.2"]

Explanation

Step 1 is to convert the child’s weight from pounds to kilograms since the dosage of morphine is prescribed in mg/kg. We know that 1 kg is approximately equal to 2.2 lb. So, the child’s weight in kg is:

51 lb ÷ 2.2 = 23.18 kg

Step 2 is to calculate the total amount of morphine the child should receive per dose. The doctor ordered 0.1 mg of morphine per kg of body weight. So, the total amount of morphine per dose is:

0.1 mg/kg × 23.18 kg = 2.318 mg

Step 3 is to calculate the volume of morphine injection to be administered. We know that the available morphine injection has a concentration of 2 mg/mL. So, the volume in mL is:

2.318 mg ÷ (2 mg/mL) = 1.159 mL

Rounding this to the nearest tenth gives 1.2 mL. So, the nurse should administer 1.2 mL of morphine injection per dose.

So, the correct answer is 1.2 mL.
