Three Nurses Before The Gates

Three nurses, unfortunately, pass away. They rise up into heaven, and  there they set out to talk to the gate keeper to plead their case for entering  paradise.  At last, the keeper points to the first nurse, which says: "I worked in an  emergency room. I treated many people, and always did my best to help,  and although sometimes we would lose patients, I still think I deserve to enter." The gate keeper glances at her file and admits her to heaven. The second nurse then says, "For myself, I used to work in the operating room,  assisting surgeons. It was a lot of stress, and we lost many people, but I always  did my best."  The keeper glances at her file and motions her to enter. "And you?" He asks the third nurse. "I was a case manager for an HMO. I worked with thousands of patients."  She answers confidently.  The gate keeper takes a long and careful at her file. He pulls out a calculator  and starts entering digits quickly, looking back from time to time at the woman's  file. After a few minutes of this, the keeper looks up, smiles at her and says:  "Congratulations! You've been admitted to heaven... for five days!"
