So the real QT is shorter, but the computer does not mention the U-wave, and the U-wave is as important as the T-wave in predicting cardiac dysrhythmias. mEq of K pushed fast and circulated theoretically would raise serum K immediately by 1.0 This is an extremely dangerous ECG. The K returned at 1.9 This is extremely low for DKA.

Could the dysrhythmias have been prevented? It would be difficult to get a nurse to give it faster! During the resuscitation, I ordered 10 mEq KCl push, but the patient received 40 mEq of KCl, push (far more than recommended) The resident had ordered 40 mEq and that is what the nurses heard. Is 40 mEq too much? mEq/L, from 1.9

She had home health nurse visits, and a BMP was sent the next day (the day prior to admission, presumably after 120 mEq of KCl replacement -- if she was taking as directed). It would be difficult to get a nurse to give it faster! mEq of K pushed fast and circulated theoretically would raise serum K immediately by 1.0
