A patient in the intensive care unit is being prepared to receive continuous arteriovenous hemofiltration. Which of the following sites will be used for this type of dialysis?
1. femoral vein
2. femoral artery and vein
3. brachial artery and vein
4. brachial vein
2
Rationale: The femoral artery and vein are utilized with continuous arteriovenous hemofiltration because of the ease of access and the size of the vessel. Continuous venovenous hemofiltration and continuous venovenous hemofiltration-dialysis use a vein only. The brachial artery and vein would be considered too small to support the filtration needed for the body and would not be used.
