My second chemo session was successful, but also somewhat confusing. The nurse administering the prescribed and allergic reaction-causing med was prepared to simply do the same procedure a second time. When I and my wife stressed the seriousness of my initial adverse reactions she hesitated with apparent uncertainty, causing me to state flatly that if the situation was not addressed I was prepared to refuse that chemo drug. She took the time to closely review the record of the first chemo session, my apparently limiting existing medical conditions and my bloodwork results from a few hours earlier. With respect to the latter, she observed a high potassium reading--5.6 v. specced high of 5.0--and started increasing my potassium (kind of sounds irrational?) through my port. She also noted that I had been heavily dosed with Benadryl at the initial session and proposed doing the same, except at the outset rather than as a response to the allergic reaction. I elected (somewhat grudgingly) to discontinue my reluctance and rely on her recommendation. The result was a sleeping patient and an uneventful administration of the chemo. After all was over, I apologized if I had sounded a bit hostile and thanked her for her patience and attention to my concern. I woke this morning feeling as well as usual and encouraged that apparently future sessions will be similarly uneventful.
