 Correct Answers
If only 500ml blood was lost during the operation (as measured by the anaethetist), then for Hg to drop to 4.4 and 3.2 must can only be due to massive blood loss, post-operatively.
i.e after the operation. Yes, either the doctor cut something, a clip fell off or blood was oozing.
Hence he suffered massive post operative blood loss. Answer = B
Since massive blood loss (even 1/3 blood) can result in left ventricular failure, and there was NO history of heart problems,
the left ventricular failure can be attributed to the substantial post operative blood loss. Answer = 2
