A nurse is preparing to administer heparin 2,000 units by IV bolus. Available is heparin injection 5,000 units/mL. How many mL should the nurse administer?
Correct answer
A
Rationale
The correct answer is A: 0.4 mL. To calculate the mL needed, use the formula: mL = dose needed (units) / concentration (units/mL). In this case, 2,000 units / 5,000 units/mL = 0.4 mL. This ensures the correct dosage is administered accurately. Choice B, 0.5 mL, is incorrect because it doesn't match the calculated value. Choices C and D, 0.6 mL and 0.7 mL respectively, are also incorrect as they are not the precise calculation based on the given information.
