A nurse is preparing to administer 150 mg of an antibiotic IM. Available is 2 g/10 mL. Haw many mi 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 ["0.8"]
Determine the desired dose.
The nurse needs to administer 150 mg of the antibiotic.
Calculate the available dose per mL.
The available antibiotic is 2 g/10 mL. This means that each mL of the solution contains 2 g / 10 mL = 0.2 g = 200 mg of the antibiotic.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/mL) = 150 mg / 200 mg/mL = 0.75 mL
Round the volume to the nearest tenth.
Volume = 0.8 mL

Correct Answer is ["48"]
Explanation
The patient has a new prescription for:
16 units of regular insulin daily
32 units of NPH insulin subcutaneously at breakfast
To calculate the total number of units the nurse should prepare in the insulin syringe, we need to add the units of each type of insulin:
Total units = Regular insulin units + NPH insulin units Total units = 16 units + 32 units Total units = 48 units
Correct Answer is ["0.8"]
Explanation
Determine the desired dose.
The nurse needs to administer 3,800 units of heparin.
Calculate the available dose per mL.
The available heparin is 5,000 units/mL.
Calculate the volume to be administered.
Volume = Desired dose (units) / Concentration (units/mL) = 3,800 units / 5,000 units/mL = 0.76 mL
Round the volume to the nearest tenth.
Volume = 0.8 mL
