Question 1 of 5
A nurse caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous infusion at 1,200 U/hr. Available is heparin 25,000 units in 500 mL DSW. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 24
Rationale:
Rationale:
To determine the mL/hr rate, calculate the total units of heparin in 1 hr (1,200 U) and then set up a proportion using the volume of heparin solution. Given 25,000 U in 500 mL, 1,200 U will be in x mL. Cross multiply to find x = 24 mL/hr. This is the correct answer as it ensures the prescribed dose of heparin is administered accurately. Other choices are incorrect as they do not align with the calculations based on the prescribed infusion rate and concentration of heparin solution.
