Calculation
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.
mL per dose
Explanation & Rationale
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. To the nearest hundredth = 0.88
