문제
Pleural fluid protein is 3.6 g/dL and serum protein is 6.0 g/dL. Based on the protein component of Light's criteria, how should the fluid be classified?
1Transudate because the ratio is below 0.2
2Exudate because the pleural-fluid to serum protein ratio is 0.60✓ 정답
3Transudate because serum protein exceeds pleural protein
4Classification requires urine protein electrophoresis
해설
The protein ratio is 3.6/6.0 = 0.60. A ratio greater than 0.5 meets one of Light's criteria for an exudate.
