i had problems with bgm during my shift. i recalibrated a couple of times to verify accuracy & changed batteries (which resulted in loss of recorded bgls). one particular pt. who bottoms out & has extremes of hyper/hypoglycemia consistently had a fall after a change from a private room to a semiprivate room without injury & occuring several hours after my shift. however, during falls assessment of vs, his bgl was 55; an ir was done, md notified, etc. however, on call was on duty and questioned why i gave 20u novolog/rather than 10u to the resident @hs. my handwriting was misinterpreted by oncoming lpn as 400 but i wrote 408 on mar (but i was accused of lying as a result-and bgm #s did not match 400 or 408 either due to bgm calibration issues; and i was subsequently fired for a med documentation error because state was in house and my 408 could not be verified against bgm. i have been a sterling rn til now & would take a lie detector test to affect that i gave appropriate insulin per bgl result. i'm devastated!! threats of being reported to state to boot! how do i salvage my new career & stellar reputation? i gained monumentous experience in last 3 months, how can i claim now without looking incompetent. am i doomed before i ever get started?
