A nurse is preparing to administer morphine 0.1 mg/kg IV bolus every 3 to 4 hr PRN for pain to a school-age child who weighs 51 lb. Available is morphine injection 2 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
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.

Explanation
1 Tablespoon = 15mls
therefore, the nurse should administer 1 Tablespoon
Correct Answer is ["1.1"]
Explanation
First, we need to calculate the total daily dose of methimazole for the child.
The child weighs 55 kg and the prescribed dose is 0.3 mg/kg/day, so the total daily dose is 55 kg * 0.3 mg/kg/day = 16.5 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: 16.5 mg/day / 3 = 5.5 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: 5.5 mg per dose / 5 mg per tablet = 1.1 tablets per dose.
