Q

What causes a ping on the right. What do they sound like?

A
  1. spiral colon causes a small dull ping
  2. RDA causes a more metallic ping and extends more cranially past the last rib
  3. cecal distention: may cause a bit of a metallic ping

  5. masses
  6. gas distension
  7. fluid
  8. volvulus
    (9. maybe RDA)
17

What are 7 clinical pathology tests that can be done?

A
  1. CBC (inflam)
  2. biochemistry (electrolyte imbalances)
  3. blood gas
  4. urinalysis
  5. rumen fluid analysis
  6. paracentesis
18
Q

What are two 2 reasons to do fecal examination?

A
  1. diagnosis

2. disease control (salmonella)

19
Q

What are 5 characteristics of feces that can be determined?

A
  1. consistency
  2. colour
  3. particle size
  4. foreign material
  5. parasites
20
Q

What are 4 tests that can be done on feces to get a diagnosis of diarrhea?

A
  1. culture
  2. PCR
  3. toxin assay
  4. fecal egg count
21
Q

What are 4 reasons to tube a ruminant?

A
  1. relieve bloat
  2. administer fluid
    3.
22
Q

What are 4 reasons to tube a ruminant?

A
  1. relieve bloat
  2. administer fluid
  3. transfaunation
  4. collect fluid
23
Q

What is the colour, consistency, odor, pH, protozoal activiy, gram stain, chloride concentration of rumen

A
  1. olive, brownish green
  2. slightly viscous
  3. aromatic, strong odor
  4. multiple forms, active motion
  5. predominantly gram negative
    6.
24
Q

Paracentesis can be used to diagnose what? Is it always useful?

A
  1. diagnose peritonitis

2. may or may not be useful because the peritonitis can be walled off

25
Q

What are two ways the alimentary tract can be imaged?

A
  1. radiography

2. ultrasonography

26
Q

What are two ways the alimentary tract can be imaged?

A
  1. radiography

2. ultrasonography

27
Q

how can hardware disease be detected with ultrasonography? with radiography?

A
  1. ultasonography: can put probe just caudal to xiphoid or a little left and look to see if the reticulum moves–fluid or lack of movement is indicative of reticuloperitonitis
  2. radiography: with radiographs of the caudal lungs may be able to see the wire
28
Q

How can use diagnose small intestinal distention with ultrasound?

A

look from right body wall

29
Q

When is exploratory laparotomy be donw? how is it done?

A

can be used as a diagnostic tool in non-specific GI lesions, particularly dairy cattle

standing procedure

30
Q

What are 5 special considerations for camelids?

A
  1. their body condition cannot be determined by distance exam, must touch
  2. very good at hiding clinical signs
  3. very social and so can be easily stressed
  4. assess management and feeding practices because often hobby farms may have parasites or improper feed
  5. the stomach has 3 compartments
31
Q

What is C3 of camelids prone to?

A

ulcers

32
Q

What is the function of C1, C2 in camelids?

A

fermentation, nutrient/water absorption, feed transit
