A patient who had a large portion of the stomach surgically removed will need to receive vitamin B12 for life due to which condition?
Acquired hemolytic anemia
Pernicious anemia
Iron-deficiency anemia
Sickle cell anemia
The Correct Answer is B
Choice A rationale
Acquired hemolytic anemia is a condition where the body destroys red blood cells faster than it can produce them, but it is not typically associated with the need for lifelong vitamin B12 supplementation following stomach surgery.
Choice B rationale
Pernicious anemia is a condition that can develop in patients who have had a large portion of their stomach surgically removed. This is because the stomach plays a crucial role in the absorption of vitamin B12. Without sufficient stomach tissue, the body may not be able to
absorb enough vitamin B12 from food, leading to a deficiency. Therefore, these patients often require lifelong vitamin B12 supplementation.
Choice C rationale
Iron-deficiency anemia is typically caused by a lack of iron in the diet, not a lack of vitamin B12. Therefore, patients with this condition would not typically require lifelong vitamin B12 supplementation following stomach surgery.
Choice D rationale
Sickle cell anemia is a genetic disorder that affects the shape and function of red blood cells. It is not typically associated with the need for lifelong vitamin B12 supplementation following stomach surgery.

Correct Answer is C
Explanation
Choice A rationale
Aspartate aminotransferase (AST) is an enzyme that is found in various tissues, including the liver. Elevated levels of AST can indicate liver damage or disease.
Choice B rationale
Albumin is a protein that is made by the liver. It helps keep fluid in the bloodstream so it doesn’t leak into other tissues. Low levels of albumin can indicate liver disease.
Choice C rationale
Lipase is an enzyme that is produced by the pancreas and used in the digestion of fats. It is not a marker of liver function.
Choice D rationale
Alanine transaminase (ALT) is an enzyme found mostly in the cells of the liver and kidney. Much like AST, high levels of ALT can indicate liver damage or disease.
