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 ["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
Correct Answer is ["3.2"]
Explanation
Convert the infant's weight to kg.
The infant weighs 12 lb.
1 lb is approximately equal to 0.45 kg.
Infant's weight in kg = 12 lb x 0.45 kg/lb = 5.4 kg
Calculate the dose per administration.
The prescribed dose is 15 mg/kg/dose.
Dose per administration = 15 mg/kg/dose x 5.4 kg = 81 mg/dose
Calculate the volume to be administered.
The available concentration is 125 mg/5 mL.
Volume = Dose per administration (mg) / Concentration (mg/mL) = 81 mg / (125 mg/5 mL) = 81 mg x (5 mL/125 mg) = 3.24 mL
Round the volume to the nearest tenth.
Volume = 3.2 mL
