Rationale: Night terrors typically occur during non-REM sleep and are more common in young children. They may be associated with sleepwalking (somnambulism) and usually begin in early childhood.

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.
