A nurse is preparing to administer filgrastim 10 mcg/kg subcutaneous to a child who weighs 71 lb. Available is filgrastim injection 300 mcg/mL. 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.)
The Correct Answer is ["1.1"]
To calculate the dosage of filgrastim, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 71 pounds, which is approximately 32.27 kilograms (71 lb / 2.2 kg/lb). Next, multiply the child's weight in kilograms by the dosage prescribed, which is 10 mcg/kg. This results in a total dosage of 322.7 mcg (32.27 kg * 10 mcg/kg). Finally, divide the total dosage needed by the concentration of the available medication to find out how many mL to administer. The filgrastim injection available is 300 mcg/mL, so you would administer approximately 1.08 mL (322.7 mcg / 300 mcg/mL), which rounds to 1.1 mL when rounded to the nearest tenth.

Explanation
To administer the correct dose of hydrocortisone, which is 7.5 mg, when only 5 mg tablets are available, the nurse would need to give one and a half tablets to achieve the desired dose. 7.5 mg divided by 5 mg per tablet equals 1.5 tablets.
Correct Answer is ["0.2"]
Explanation
To calculate the amount of enoxaparin to administer, you would use the formula: (desired dose ÷ available dose) × available volume. For this scenario, it would be (20 mg ÷ 30 mg) × 0.3 mL, which equals 0.2 mL.
