Rationale: The correct answer is A: Sitting independently. By 11 months, most infants can sit independently. This milestone usually precedes walking, which typically occurs closer to 12 months. Turning a doorknob and building a tower of four cubes involve more complex motor skills that are typically achieved later in development. Therefore, at 11 months, sitting independently is the milestone that the nurse would expect an infant to have achieved.

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus.
