Connie, my thoughts are exactly the same as yours! Your husband needs to ask about these sorts of things!!! Im sure he is not feeling the best but he must pay attention to this sort of thing. He may not have his BP that high, some patients run high while others run low and for them its just how they are, its normal. Your husband needs to be his own advocate at times and ask about a nurse refusing his fluids. Whats the doc say about that? If it was me who was supposed to get fluids then when I got there the nurse refused them Id want to know why and have it explained to me so I had a better understanding of how this sort of thing can get changed by nurses. I suggest talking to the doc right away and getting to the bottom of why fluids were not given. Yes, you are correct... dehydration can wreck havoc on blood pressure readings.
