A nurse is preparing to administer methy prednisolone 7 mg/kg/day IM in two divided doses to a school-age child who weighs 64 lb. Available is methyiprednisolone 20 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.)

Answer and Explanation

The Correct Answer is ["5.1"]

First, convert the child's weight from pounds to kilograms: 64 lb / 2.205 lb/kg = 29.02 kg

Calculate the total daily dose of methylprednisolone needed: 7 mg/kg x 29.02 kg = 203.14 mg

Calculate the dose per administration: 203.14 mg / 2 = 101.57 mg

Calculate the volume of methylprednisolone to administer per dose: 101.57 mg / 20 mg/mL = 5.0785 mL

Round to the nearest tenth: 5.0785 mL rounded to the nearest tenth is 5.1 mL.

Correct Answer is ["1.9"]

Explanation

Determine the desired dosage:

The nurse needs to administer 187 mg of isoniazid.

Determine the volume per dose:

The isoniazid injection contains 100 mg per 1 mL.

The nurse needs to administer 187 mg per dose.

To find the volume per dose, we can set up a proportion:

100 mg / 1 mL = 187 mg / x mL

Cross-multiplying gives us:

100x = 187

Dividing both sides by 100, we get:

x = 1.87 mL

Round the answer to the nearest tenth:

Rounding 1.87 to the nearest tenth gives us 1.9 mL.

A. oz B. lb C. mcg D. mL

Correct Answer is C

Explanation

A) oz (ounce): Ounce is a unit of weight commonly used in the imperial system, particularly in the United States. It's often used to measure smaller weights in food and other household items, but it is not a metric unit.

B) lb (pound): Pound is another unit of weight in the imperial system. It is frequently used to measure body weight and heavier objects, but it is not a metric unit, making it unsuitable for standardized medical documentation in metric units.

C) mcg (microgram): Microgram is a metric unit of weight used to measure very small quantities, such as doses of medication or certain laboratory measurements. It's essential in medical and scientific contexts for its precision and standardization.

D) mL (milliliter): Milliliter is a metric unit, but it measures volume, not weight. It is often used in medical dosing and laboratory measurements to denote liquid quantities, ensuring accurate and consistent fluid measurements.
