Which of the following is NOT a component of the nephrotic syndrome?
1) Massive proteinuria
2) Hypoalbuminemia
3) Lipiduria
4) Neutrophiluria
The nephrotic syndrome includes massive proteinuria, hypoalbuminemia, generalized edema, and hyperlipidemia with lipiduria.

A patient with chronic kidney disease is found to have a serum uric acid level of 8.0 mg/dL. This is most likely due to:
1) Excessive dietary purine intake
2) Decreased glomerular filtration rate
3) Excessive lactate production
4) Impaired tubular secretion of uric acid
Chronic kidney disease can lead to hyperuricemia due to decreased glomerular filtration rate, resulting in decreased excretion of uric acid by the kidneys.
