The nurse notes that a child has lost 3.6 kg (8 lb) after 4 days of hospitalization for acute glomerulonephritis. What is the most likely cause of this weight loss?
 
  a. Poor appetite
  b. Reduction of edema
  c. Restriction to bed rest
  d. Increased potassium intake

Question 2

What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?
 
  a. Infarction of renal vessels
  b. Immune complex formation and glomerular deposition
  c. Bacterial endotoxin deposition on and destruction of glomeruli
  d. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Answer to Question 1

ANS: B
This amount of weight loss in this period is a result of the improvement of renal function and mobilization of edema fluid. Poor appetite and bed rest would not result in a weight loss of 8 lb in 4 days. Foods with substantial amounts of potassium are avoided until renal function is normalized.

Answer to Question 2

ANS: B
After a streptococcal infection, antibodies are formed, and immune-complex reaction occurs. The immune complexes are trapped in the glomerular capillary loop. Infarction of renal vessels occurs in renal involvement in sickle cell disease. Bacterial endotoxin deposition on and destruction of glomeruli is not a mechanism for postinfectious glomerulonephritis. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation is the pathology of renal involvement with bacterial endocarditis.
