Question Answer
what are the core horse vx?WEE, EEE, WNV, Tetanus, rabies
what is the scale for the BCS for a horse?1-9
loosely describe how to do a BCS on a horseat level of neck you're looking for deposition of fat-- need to really palpate, give a good squeeze. Then withers-- most horses wont have fat on withers. Ribs- should be able to feel them. if can see, score below five. if can't see them, 5 or above (ribs are most reliable part of getting BCS.) Then point of shoulder....where is it? (just behind triceps and just before you can really palpate the ribs) so just behind triceps, bit higher....if fat horse, check pics of fat ponies, will see fat bulging there. If back is level, how reliable is this? depends on amount of mm bc exercise--- if no exercise, wont have a level back bc dec in mm....doesn't really mean they have a low BCS. And then tail head (make sure horse is a nice horse if you do this)
what is viborgs triangle? what should it look like on a normal horse?It is the boundaries of the gutteral pouch. Look for swellings in this area to indicate problems (should be flat) Rostral: ramus of mandible. Ventral: linguofacial vein. Caudodorsal: tendon of sternocephalicus mm
where do we usually check the pulse on the head?transverse facial artery, or under the mandibular rim (but difficult)
what are the structures you should be checking in the horse's throat latch? Guttural pouch, Retropharyngeal lnn, Skin tenting, Palpation Larynx, Palpate neck muscles.... and never forget the trachea (sounds diff from lung sounds, worth checking)
where can you skin tent to assess hydration?throat latch
CQ: If it's a yearling horse, what is the major GI parasite?parascaris equorum
what are the venipuncture sites in horses?JUGULAR, cephalic , lateral thoracic
what are the landmarks for thoracic auscultation? If you need to hear the lung sounds better, what can you do?(horse has 18 ribs!) basically from caudal edge of triceps, lateral edge of epaxial mm, and 5th costochondral junction to dorsal end of 17th rib as a gently curved line. DON'T FORGET THE TRACHEA!!!! If you want to hear their lung sounds better, use a rebreathing bag
horse resp rate?8 – 15 bpm
what is the physiological (normal) murmur in a horse?2nd degree AV block (dropped beat)
**GI tract-- you should listen to the abdomen in all 4 quadrants. What are the 4 quadrants and what is in them for you to listen to??UPPER LEFT: left dorsal colon. UPPER RIGHT: ileocecal valve. LOWER LEFT: small intestine and left ventral colon. LOWER RIGHT: cecum, right ventral colon, small intestine (listening in the blue circle)
do you palpate limbs prox to distal or distal to prox?Palpation proximal to distal
last thing you do in a PE?temperature-- it will mess up HR and make them generally pissed at you
