I am a nurse. I have a patient on several meds. Primary dx is dementia. Patient also has GERD and IBS. Recently suffered from fx hip, c-diff, and pneumonia. Patient was on several PPI's and opiods. Patient has been vomiting for about 2 months now despite use of antinausea meds. A few days ago we discontinues several meds in hopes that her vomiting would cease. Patient now has only 1 PPI and 1 opiod as well as prn antinausea meds. Despite these efforts, this patient continues to vomit. Sometimes its after meals and sometimes just out of the blue. Any suggestions?
