Heparin 5,000 Units intravenous (IV) is prescribed as a loading dose, to be administered over 5 minutes for a client with thrombophlebitis. The vial is labeled, "10,000 units/mL." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

To calculate the volume of heparin solution, we need to use the formula: Volume (mL) = Dose (units) / Concentration (units/mL) Plugging in the given values, we get: Volume (mL) = 5,000 units / 10,000 units/mL Simplifying, we get: Volume (mL) = 0.5 mL Rounding to the nearest tenth, we get: Volume (mL) = 0.5 mL
