Case study: dale fremore was back home after spending the day at a picnic where he ate some "spoiled" potato salad. he developed severe abdominal pain and cramps, vomiting, and diarrhea. after about ten to twelve episodes of water diarrhea, mr. fremore became so pale and weak he could hardly walk. his wife took him to the hospital where he was diagnosed with severe dehydration (decreased plasma volume). mr. fremore was suffering from shock. the body has several mechanisms that can come into play to try to maintain blood pressure and blood flow when a person goes into shock. urine output usually decreases when a person is in shock. this is the result of select one: a. decreased adh secretion. b. increased renin secretion. c. increased secretion of atrial natriuretic factor. d. decreased vasoconstriction due to the stress relaxation response. e. decreased aldosterone secretion
