A client is prescribed a heparin infusion to run at 750 units/hr. The heparin is supplied as 25.000 units/250 mL. At what rate should the nurse set the infusion pump? (Do not use a trailing zero. Round to the tenth place. Do not use a trailing zero)

Rationale: Ordered dose = 750 units/hr Available concentration = 25,000 units in 250 mL Set up a proportion: 25,000 units : 250 mL = 750 units : X mL Cross multiply: 25,000 × X = 750 × 250 25,000X = 187,500 X = 187,500 ÷ 25,000 = 7.5 mL/hr
