QUESTION
Persistent vomiting causes?
OPTIONS
(A) Simple dehydration
(B) Severe dehydration
(C) Dehydration with acidosis
(D) Dehydration with alkalosis
ANSWER
(D) Dehydration with alkalosis
EXPLANATION
Persistent vomiting causes loss of hydrogen and chloride ions in gastric fluid, leading to dehydration accompanied by metabolic alkalosis. Acidosis is more typical of bicarbonate loss from severe diarrhea, while “simple” dehydration does not account for the predictable acid-base disturbance caused by repeated vomiting.
