I cut my trip short , called her doctor , and found out that she 'd be having emergency surgery at noon to drain the fluid . I make arrangements not to be at work , so I could drive down for her surgery . My aunt calls me at 5 am and tells me the surgery got moved to 6 am , so I was unable to make it down in time . After talking with my mom 's nurses I found out she did n't need her chest cracked open again .

A. The doctor did n't know what he was doing .
B. None of the above choices .
C. The nurse got the results confused .
D. The body has it 's own plan .
