Answer to Question 1
Intravenous catheters should be removed if any swelling, pain at catheter site, thrombosis, or
fever of unknown origin is noted.
Answer to Question 2
Horses are unable to vomit and are therefore susceptible to gastric rupture. Prior to
administering fluids the technician should be certain that gastric pressure is normal and that
excessive amounts of reflux (fluid) are not present. If fluids are unable to exit the stomach due
to an obstruction or other medical problem, the horse should not receive additional fluids via
the nasogastric route. The excessive fluid volume can increase gastric pressure and induce a
rupture.
