What characteristics describe an acute infection?
Symptoms occur in a confined specific location on the body.
Symptoms are severe, occur rapidly, but are short-lived.
Symptoms are not apparent and persist over a long period of time.
Symptoms are less severe and persist over a long period of time.
The Correct Answer is B
Choice A reason: Acute infections are not defined by location but by rapid onset and severity. While some infections may be localized, the hallmark is their abrupt, intense presentation, resolving quickly with treatment or spontaneously, making this choice incomplete and incorrect for fully describing acute infections.
Choice B reason: Acute infections are characterized by rapid onset, severe symptoms, and short duration, typically resolving within days to weeks. This reflects the body’s immediate immune response to pathogens, causing intense but transient symptoms, such as fever or pain, making this the correct choice.
Choice C reason: Non-apparent, prolonged symptoms describe subclinical or chronic infections, not acute ones. Acute infections present with noticeable, severe symptoms that resolve quickly, not persisting asymptomatically, making this choice incorrect for the characteristics of acute infections.
Choice D reason: Less severe, prolonged symptoms describe chronic infections, like tuberculosis, not acute infections. Acute infections feature rapid, intense symptoms that resolve quickly, not mild symptoms over time, making this choice incorrect for describing acute infections.

Correct Answer is A
Explanation
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: Hypoparathyroidism causes hypocalcemia due to low parathyroid hormone, reducing bone resorption and calcium absorption. Hypercalcemia requires increased calcium mobilization, which hypoparathyroidism prevents, making this choice incorrect for a person at risk of hypercalcemia.
Choice B reason: Chronic renal failure typically causes hypocalcemia due to impaired vitamin D activation and phosphate retention, binding calcium. Hypercalcemia is rare unless overtreated with calcium supplements, making this choice incorrect for typical renal failure scenarios.
Choice C reason: Low plasma albumin reduces bound calcium, lowering total serum calcium, not causing hypercalcemia. Free calcium may remain normal, but total calcium decreases, making this choice incorrect for a person at risk of hypercalcemia.
Choice D reason: Bedbound, immobile individuals are at risk for hypercalcemia due to increased bone resorption from lack of weight-bearing activity. Osteoclasts break down bone, releasing calcium into the blood, causing hypercalcemia, making this the correct choice.
