How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Determine the total daily dosage:
The client is prescribed 400,000 units of nystatin every 6 hours.
There are 24 hours in a day, so the medication is given 24/6 = 4 times a day.
Total daily dosage is 400,000 units/dose x 4 doses = 1,600,000 units per day.
Calculate the dosage per dose:
The medication is to be administered in divided doses every 6 hours.
There are 24 hours in a day, so the medication is given 24/6 = 4 times a day.
Dosage per dose is 1,600,000 units / 4 doses = 400,000 units per dose.
Determine the number of mL per dose:
The nystatin oral suspension contains 100,000 units per mL.
The nurse needs to administer 400,000 units per dose.
Divide 400,000 units / 100,000 units per mL = 4 mL per dose.

Divide 2.5 mg / 5 mg per tablet = 0.5 tablets per dose.
A nurse is preparing to administer enoxaparin 40 mg subcutaneous for prevention of deep-vein thrombosis. Available is enoxaparin 100 mg/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 trailing zero.)
Explanation

The client is prescribed 40 mg of enoxaparin.
Calculate the dosage per dose:
The medication is to be administered in a single dose.
Dosage per dose is 40 mg.
Determine the volume per dose:
The enoxaparin solution contains 100 mg per mL.
The nurse needs to administer 40 mg per dose.
Divide 40 mg / 100 mg per mL = 0.4 mL per dose.
A nurse is preparing to administer calcitonin 8 units/kg IM to a client who weighs 165 lb. Available is 200 units/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)
Explanation
Convert the client's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
165 lb = 165 lb / 2.205 lb/kg = 75 kg.
Determine the total dosage:
The client is prescribed 8 units/kg of calcitonin.
The client weighs 75 kg.
Dosage is 8 units/kg x 75 kg = 600 units.
Determine the volume per dose:
The calcitonin solution contains 200 units/mL.
The nurse needs to administer 600 units.
Divide 600 units / 200 units/mL = 3 mL.
A nurse is preparing to administer ketorolac 30 mg IM for loading dose. Available is ketorolac injection 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Determine the total daily dosage:
The client is prescribed 30 mg of ketorolac.
Calculate the dosage per dose:
The medication is to be administered in a single dose.
Dosage per dose is 30 mg.
Determine the volume per dose:
The ketorolac injection contains 15 mg per mL.
The nurse needs to administer 30 mg per dose.
Divide 30 mg / 15 mg per mL = 2 mL per dose.
A nurse is preparing to administer megestrol 200 mg PO to a client. Available is megestrol oral suspension 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use: trailing zero.)
Explanation
Determine the total daily dosage:
The client is prescribed 200 mg of megestrol.
Calculate the dosage per dose:
The medication is to be administered in a single dose.
Dosge per dose is 200 mg.
Determine the volume per dose:
The megestrol oral suspension contains 40 mg per mL.
The nurse needs to administer 200 mg per dose.
Divide 200 mg / 40 mg per mL = 5 mL per dose.
A nurse is preparing to administer furosemide 30 mg IM to client. Available is furosemide 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)
Explanation
Determine the total daily dosage:
The client is prescribed 30 mg of furosemide.
Calculate the dosage per dose:
The medication is to be administered in a single dose.
Dosage per dose is 30 mg.
Determine the volume per dose:
The furosemide injection contains 10 mg per mL.
The nurse needs to administer 30 mg per dose.
Divide 30 mg / 10 mg per mL = 3 mL per dose.
A nurse is preparing to administer heparin 17,500 units subcutaneous every 12 hr to a client. Available is heparin injection 20,000 units/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.
Explanation
Determine the total daily dosage:
The client is prescribed 17,500 units of heparin every 12 hours.
There are 24 hours in a day, so the medication is given 24/12 = 2 times a day.
Total daily dosage is 17,500 units/dose * 2 doses = 35,000 units per day.
Calculate the dosage per dose:
The medication is to be administered in divided doses every 12 hours.
There are 24 hours in a day, so the medication is given 24/12 = 2 times a day.
Dosage per dose is 35,000 units / 2 doses = 17,500 units per dose.
Determine the volume per dose:
The heparin injection contains 20,000 units per mL.
The nurse needs to administer 17,500 units per dose.
Divide 17,500 units / 20,000 units per mL = 0.875 mL per dose.
A nurse is preparing to administer chlorpromazine 0.55 mg/kg IM to a child who weighs 66 lb. Available is chlorpromazine 25 mg/mL for injection. 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.)

Convert the child's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
Divide: 66 lb / 2.205 lb/kg = 30 kg.
Determine the total dosage:
The child is prescribed 0.55 mg/kg of chlorpromazine.
The child weighs 30 kg.
Total dosage is 0.55 mg/kg x 30 kg = 16.5 mg.
Determine the volume per dose:
