which of the following best describes acute glomerulonephritis?

Correct Answer: B

Rationale: Acute glomerulonephritis is an inflammatory kidney disease that typically follows a streptococcal infection, such as strep throat or skin infection caused by group A beta-hemolytic streptococcus. The infection triggers the body's immune response, leading to the deposition of immune complexes in the glomeruli of the kidneys. This results in inflammation, damage to the glomeruli, and impaired kidney function. Symptoms of acute glomerulonephritis may include hematuria (blood in the urine), proteinuria (protein in the urine), edema, hypertension, and decreased urine output. It is important to diagnose and manage acute glomerulonephritis promptly to prevent complications and promote recovery. Other answer choices do not accurately describe the typical etiology or presentation of acute glomerulonephritis.

Correct Answer: B

Rationale: EBV is not typically associated with nasopharyngeal T-cell lymphoma but is linked to B-cell lymphomas and carcinomas.

Correct Answer: D

Rationale: Around 48% of allergic rhinitis patients also have asthma, showing the strong link between the two conditions, as allergic inflammation can affect both the upper and lower airways.

Correct Answer: D

Rationale: Reye's syndrome is a rare but serious condition that primarily affects children and teenagers. It is characterized by swelling in the liver and the brain. The development of Reye's syndrome has been linked with the use of aspirin during viral infections, particularly influenza and varicella (chickenpox). Therefore, the correct answer is D. Varicella. It is crucial to avoid giving aspirin to children and teenagers during these viral infections to reduce the risk of developing Reye's syndrome.

Correct Answer: D

Rationale: Autistic spectrum disorder includes stereotyped movements, not their absence. Defective social communication, fixated interests, and restricted routines are hallmark features.
