How much anticoagulant would have to be removed from the collection bag given a donor who weighs 90 lb?

• A. 12 mL
• B. 15 mL
• C. 20 mL
• D. 23 mL

Answer: (A)

To determine how much anticoagulant should be removed from the collection bag for a donor who weighs 90 lb, it's important to understand the standard ratio of blood to anticoagulant in blood collection. Generally, the volume of anticoagulant used in blood collection is calibrated based on the weight of the donor. For a donor weighing 90 lb, the expected volume of blood collected would generally be around 500 mL. The typical anticoagulant-to-blood ratio is approximately 1:7, which means for every 7 parts of blood, there is about 1 part of anticoagulant. Using this ratio, we can calculate the appropriate volume of anticoagulant required for a smaller-sized donor. For a donor weighing 90 lb, the amount of anticoagulant needed is proportionately less compared to a standard collection. The anticoagulant volume in a collection bag for a standard adult donor is usually around 63 mL, but for a 90 lb donor, this volume would need to be adjusted down. Removing 12 mL of anticoagulant allows for a more compatible ratio for the smaller total volume collected, ensuring that the blood remains adequately anticoagulated while also preventing the complications associated with having too much anticoagul
