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 to the nearest tenth.)
Correct answer
0.4
Rationale
To calculate the mL of heparin to administer, use the formula: desired dose (4,000 units) ├À concentration (10,000 units/mL) = X mL. 4,000 ├À 10,000 = 0.4 mL. The correct answer is 0.4 mL because it accurately represents the calculated dose needed for the client. Other choices are incorrect as they do not align with the correct calculation.
