NAVLE (North American Veterinary Licensing Examination) Practice Exam 12
Practice exam for NAVLE (North American Veterinary Licensing Examination).
Question 1
MEDIUMA 6-year-old neutered male Labrador Retriever is presented for acute onset abdominal distension and nonproductive retching after getting into the trash. On exam: hypersalivation, tachycardia (160/min), pale mucous membranes, prolonged CRT, and a tympanic cranial abdomen. Which immediate action is most appropriate while preparing for definitive treatment?
The presentation is classic for gastric dilatation-volvulus (GDV) with shock. Immediate priorities are cardiovascular stabilization (IV fluids) and rapid gastric decompression to improve venous return and ventilation. If an orogastric tube cannot be passed due to volvulus, percutaneous trocarization/needle decompression is indicated while preparing for surgery. Observation or oral meds are inappropriate; abdominocentesis is not the priority; proceeding to surgery without stabilization increases anesthetic risk.
