QUESTION
A cow with an abomasal disorder has?
OPTIONS
(A) Metabolic alkalosis, hence physiological saline or Ringer’s solution is administered IV
(B) Metabolic acidosis, hence lactated Ringer’s solution is administered IV
(C) Mixed acid base disorder, hence Dextrose- saline IV is administered
(D) Both (b) and (c) are correct
ANSWER
(A) Metabolic alkalosis, hence physiological saline or Ringer’s solution is administered IV
EXPLANATION
Abomasal outflow disorders commonly sequester hydrochloric acid, producing hypochloremic metabolic alkalosis; isotonic saline or a chloride-rich balanced solution is therefore appropriate to restore volume and chloride. Metabolic acidosis is not the typical primary disturbance, so the alternatives based on acidosis are incorrect.
