A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
To answer this question, we need to use the formula for calculating the dosage of medication:
Dose ordered / Dose on hand = Amount to administer
The calculation is: 4,000 units / 10,000 units/mL = 0.4 mL.
