Question

Quizplus · Accepted Answer

Cyanocobalamin (B12) is essential for the absorption of iron and the formation of red blood cells, and it is absorbed in the small intestine. Since a partial gastrectomy removes a large portion of the stomach, which is responsible for producing intrinsic factor necessary for B12 absorption, the client will need lifelong parenteral B12 supplementation. Thiamine (B1) is not affected by gastrectomy and can be adequately absorbed in the upper small intestine. Niacin (B3) and pyridoxine (B6) are also absorbed in the upper small intestine, and deficiencies due to gastrectomy are rare.
