Portal hypertension from liver cirrhosis may cause which manifestation?
Ascites
Hypoalbuminemia
Hypoglycemia
Hyperkalemia
The Correct Answer is A
Choice A reason: Portal hypertension from liver cirrhosis increases pressure in the portal vein, causing fluid leakage into the peritoneal cavity, leading to ascites. This occurs due to impaired liver function, reduced albumin, and increased hydrostatic pressure, making ascites a common manifestation and the correct choice.
Choice B reason: Hypoalbuminemia results from liver cirrhosis due to decreased hepatic protein synthesis but is not a direct manifestation of portal hypertension. It contributes to ascites by reducing oncotic pressure but is a separate consequence of liver dysfunction, making this choice incorrect.
Choice C reason: Hypoglycemia is not typically caused by portal hypertension. Cirrhosis may impair glucose regulation due to reduced glycogen storage, but portal hypertension primarily affects vascular dynamics, leading to ascites or varices, not low blood sugar, making this choice incorrect.
Choice D reason: Hyperkalemia is not a direct result of portal hypertension. Cirrhosis may cause electrolyte imbalances indirectly, but portal hypertension primarily leads to fluid shifts and vascular complications like ascites, not potassium elevation, making this choice incorrect for the described condition.

Correct Answer is D
Explanation
Choice A reason: Passive natural immunity occurs via natural antibody transfer, like breast milk. Infusion of antibodies is an artificial process, not natural, providing temporary protection, making this choice incorrect for the described immunity type.
Choice B reason: Active artificial immunity involves vaccination, stimulating the body to produce its own antibodies. Antibody infusion provides pre-formed antibodies, not active production, making this choice incorrect for the described immunity mechanism.
Choice C reason: Active natural immunity results from natural infection, leading to the body’s antibody production. Infusion of antibodies is artificial and passive, not requiring immune activation, making this choice incorrect for the scenario.
Choice D reason: Passive artificial immunity occurs when pre-formed antibodies are infused, providing immediate but temporary protection without immune system activation. This matches the described antibody infusion, making this the correct choice.
Correct Answer is A
Explanation
Choice A reason: Pernicious anemia, caused by vitamin B12 deficiency from lack of intrinsic factor, leads to neurological damage, causing paresthesia (tingling/numbness). This is specific due to demyelination of peripheral nerves, making this the correct manifestation.
Choice B reason: Jaundice occurs in hemolytic anemias due to red cell breakdown, not pernicious anemia. B12 deficiency causes megaloblastic anemia without significant hemolysis, making jaundice non-specific and incorrect for this condition.
Choice C reason: Thrombocytopenia, low platelet count, is not specific to pernicious anemia. It may occur in other conditions but not typically in B12 deficiency, which primarily affects red cells, making this choice incorrect.
Choice D reason: Severe pain is not a specific feature of pernicious anemia. It may occur in sickle cell anemia or other conditions, but B12 deficiency causes neurological symptoms like paresthesia, making this choice incorrect.
