My 88-year-old Mom (one month post-partial hip replacement) saw her PCP last week and he did bloodwork to check a few things like low hemoglobin level. His office called and said all was within normal range. When I was finally able to check the results online through the patient portal, I was shocked! Most of the red blood cell numbers were out of whack including hemoglobin which was 10 and her potassium level was a sky-high 5.9! At the hospital her potassium was not even that high and they made her drink that stuff that binds to the potassium and is excreted in stool. I know from past experience with my Dad, a high potassium level is dangerous and could lead to a heart attack. I called the PCP's office but, of course, he left early since it was Friday. His nurse ASSURED me that someone would get back to me TODAY. Right. Didn't happen. Supposedly the doctor on call would review the numbers and let me know what should be done. I am mad enough right now to spit fire and certainly angry enough to change to a different primary care doctor. Did her PCP not even look at the test results? How could he say a 5.9 potassium level is normal??! Not sure what to do about this. Mom has been lethargic and has no appetite to speak of. I'm trying to encourage her to drink water but am at a loss as to what to do now. Any suggestions?
