A school aged child is being evaluated for possible glomerulonephritis. During the physical exam the nurse recognizes that which of the following, is a possible cause?

The correct answer is D: Treatment for strep throat within the last two weeks. Glomerulonephritis can be caused by a complication of untreated strep throat known as poststreptococcal glomerulonephritis. This occurs when the immune system mistakenly attacks the kidneys while fighting off the strep infection. The other choices are incorrect because: A) a runny nose and itchy eyes suggest allergies or a mild respiratory infection, not glomerulonephritis; B) treatment for a viral illness does not typically lead to glomerulonephritis; C) treatment for a urinary tract infection is unlikely to cause glomerulonephritis unless there are complications; and E-G) additional options were not provided.
