Simulated
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.) mL.
Correct answer
A
Rationale
The correct answer is A: 0.4 mL. To calculate the amount of heparin to administer, use the formula: Desired dose (4,000 units) / Stock dose (10,000 units/mL) = Volume to administer in mL. Therefore, 4,000 units / 10,000 units/mL = 0.4 mL. This is the correct answer as it accurately calculates the volume of heparin needed for the patient. Other choices are incorrect because they do not provide the accurate calculation based on the given information.
