The patient has two concurrent IV infusions in the same line via Y-site. Infusion A is 80 mL/hr; Infusion B is 40 mL/hr. What is the total rate?

The patient has two concurrent IV infusions in the same line via Y-site. Infusion A is 80 mL/hr; Infusion B is 40 mL/hr. What is the total rate?

• A. 90 mL/hr
• B. 120 mL/hr
• C. 60 mL/hr
• D. 100 mL/hr

Answer: (B)

When two IV infusions share the same line through a Y-site, their flows combine. The patient receives the sum of both infusion rates because the fluids merge and enter the bloodstream together. So you simply add the rates: 80 mL/hr plus 40 mL/hr equals 120 mL/hr. In practice, confirm that the medications are compatible for administration through the same line and set the IV pump to the total rate to ensure accurate delivery.
