Question 1 of 5
A nurse is preparing to administer a continuous heparin infusion at 1600 units/hr. Available is heparin 25,000 units in dextrose 5% in water (D,W) 500 ml. The nurse should set the IV pump to deliver how many mL/hr?
Correct Answer: A
Rationale:
To determine the mL/hr rate for heparin infusion, we can use the formula: (Desired dose in units/hr) x Volume of IV solution (mL) /
Total units in IV solution. In this case, (1600 units/hr) x 500 mL / 25,000 units = 32 mL/hr. This calculation ensures the correct concentration and rate of heparin infusion. Other choices are incorrect as they do not align with the calculation based on the given information.
