A patient is ordered medication 100units/kg SQ. The medication is supplied in 10000 units/mL The patient weighs 220 lbs. What should the nurse administer?
The Correct Answer is ["1"]
Let's calculate the dosage step-by-step:
1. Convert pounds to kilograms:
220 lbs/2.20462 kg = 99.8 kg
2. Calculate the total dosage:
100 units/kg x 99.8 kg = 9980units
3. Determine the concentration of the medication:
10000 units/mL
4. Calculate the volume needed:
9980 units / 10000 units/mL = 1 mL

Correct Answer is ["2.5"]
Explanation
To determine the correct volume to administer, follow these steps:
1. Convert the dose from milligrams to grams:
75 mg = 0.075 grams (since 1000 mg = 1 gram)
2. Use the concentration of the suspension to find the volume:
The concentration is 0.15 g/5 mL.
Set up a proportion: (0.15 g / 5 mL) = (0.075 g / X mL)
Solve for X: X = (0.075 g x 5 mL) / 0.15 g = 2.5 mL
3. Round to the nearest tenth:
2.5 mL is already rounded to the nearest tenth.
Correct Answer is ["2.0"]
Explanation
To determine the correct volume to administer per dose, follow these steps:
1. Calculate the total daily dosage:
The dosage is 5 mg/kg/day.
The patient weighs 120 kg.
Total daily dosage = 5 mg/kg x 120 kg = 600 mg/day.
2. Divide the total daily dosage by the number of doses per day:
The medication is to be given in three divided doses.
Dosage per dose = 600 mg/day / 3 = 200 mg per dose.
3. Determine the volume to administer per dose:
The medication is supplied as 100 mg/mL.
Volume per dose = 200 mg / 100 mg/mL = 2.0 mL.
4. Round to the nearest tenth:
2.0 mL is already rounded to the nearest tenth.
