Explain the difference between vomit and regurgitation.
The main difference between regurgitation and vomiting is that regurgitation is a passive process, while vomiting is an active process:
- Regurgitation: The passive expulsion of food, fluid, or other material from the esophagus or pharynx. Regurgitated material usually looks the same as when it was eaten, and it may be accompanied by liquid.
- Vomiting: The forceful expulsion of stomach contents from the body. Vomiting is usually accompanied by nausea, abdominal heaving, drooling, and an apprehensive appearance. Vomiting is an active process that involves a coordinated closure of the nasopharynx and glottis to protect the airway. Vomiting is usually more forceful and larger in amount than regurgitation.
A complete history and thorough examination can usually differentiate between regurgitation and vomiting.

Explain the disease process of IMHA.
Normally, a red blood cell is removed from circulation and recycled when it is no longer functional. When old RBCs circulate through the spleen, liver, and bone marrow, they are plucked from circulation and destroyed through extravascular hemolysis. This releases the iron, which is then sent to the liver for recycling in the form of a yellow pigment called bilirubin.
The spleen uses immunological cues on the surface of the RBCs to determine which cells should be plucked out of circulation.
When the immune system marks too many cells for removal, this is when IMHA begins.
300
Excessive ______ is a warning sign of poor kidney function.
"Thirst"
A pet with insufficient kidney function will not be able to make concentrated urine and will need to drink extra water to process the body's waste chemicals.
Specific gravity is a measure of how concentrated a urine sample is. Water SG is 1.000, a dilute urine sample is < 1.020 or 1.010, and a well concentrated urine sample is 1.030-1.040.
300
In patients with portosystemic shunting or liver failure, ammonia concentrations escalate predominantly because of...
Poor circulation to the liver, which decreases the liver's ability to detoxify the ammonia levels.
Metronidazole is often used to decrease population of ammonia-producing gut microbes, and lactulose acidifies the gut environment to restrict ammonia absorption.
300
Are the following clinical signs associated with small bowel or large bowel diarrhea?

Immune mediated thrombocytopenia
400
What blood analyte would be low in a case of glomerulonephritis?
Albumin
Albumin is a carrier molecule for water insoluble substances, and also is important in keeping water in the bloodstream. Without enough water, blood sludges and clots abnormally. The water will also leak into other body cavities, such as the chest and abdomen.
400
A portosystemic shunt can either be acquired or congenital. What is a portosystemic shunt?
The diseased liver resists blood flow into the organ, so new blood vessels develop to bypass the liver altogether, connecting the blood stream to the rest of the body (like finding a detour around a traffic jam). Acquired shunts are formed over time after a liver injury, and congenital shunts are a birth defect.
400

Intestinal tract.
Many primary conditions obstruct the CBD:
Inflammation in the surrounding area (eg. pancreatitis, duodenitis, duodenal foreign body), cholelithiasis, GB mucocele, cholecystitis, neoplasia, bile duct malformations, parasites, extrinsic compression, fibrosis, and bile duct structure.
Clinical signs (acute EHBDO): lethargy, cyclic fever, jaundice, elevated T.Bili (within 4 hours of obstruction taking place), inappetence or polyphagia (due to fat maldigestion from the lack of bile acids).
500
Please explain how miralax helps in cases of constipation?
Miralax (polyethylene glycol) acts by pulling water from the body into the intestinal tract during stool formation, leading to a softer stool.

Amyloidosis refers to a group of diseases characterized by abnormal deposition of an insoluble, fibrous, proteinaceous substance (amyloid) in tissue. Name one possible cause of this disease.
Chronic persistent inflammatory diseases
Cancers
Amyloidosis may be difficult to diagnose based on clinical signs because these will depend on the location and the organs affected.
There is no specific treatment that can prevent the development of amyloid, or promote resorption of amyloid. Elimination of the source of chronic inflammation may slow amyloid deposition.
This is commonly seen in shar peis and abbysinian cats.

Fill in the blanks:
The gallbladder functions to store _____ between meals. When the patient eats, the fatty acids and amino acids trigger the release of cholecystokinin, stimulating _________ contraction. When it contracts, stored bile empties into the duodenum where it aids in digestion and absorption of dietary _____.
The gallbladder functions to store bile between meals. When the patient eats, the fatty acids and amino acids trigger the release of cholecystokinin, stimulating gallbladder contraction. When it contracts, stored bile empties into the duodenum where it aids in digestion and absorption of dietary fat.
600
When does constipation become obstipation?
Obstipation occurs when constipation becomes a more permanent and continuous problem. Obstipation is a more severe form of constipation that occurs when a pet is unable to pass feces due to a buildup of hard, dry stool. Obstipation is often associated with a serious, permanent, or irreversible medical condition.

700
What is myasthenia gravis?
Myasthenia gravis is the condition where the neuromuscular junctions are diseased. The acetylcholine message from the nerve trying to stimulate the muscle is quickly blunted because of damage to the nerve/muscle interface. This can be congenital or acquired (immune mediated).
800
What disease causes the following symptoms:
- Weight loss
- Lethargy
- Hypertension
- PU/PD
- Anorexia
- Nausea/vomiting
- Pitting edema
Protein Losing Nephropathy (PLN)
The most severe complication of PLN is thromboembolic disease (antithrombin III, a protein that stops blood clots from forming when they shouldn't, is lost in the urine). This makes them prone to clots, and may be fatal if one reaches the lungs or brain.
800
What is cholecystitis? What is the most common treatment of choice?
Inflammation of the gallbladder (a common complication of cholelithiasis, extrahepatic bile duct obstruction, and other diseases). Usually treated by performing a cholecystectomy in most cases.

Addison's = Hypoadrenocorticism, a lack of glucocorticoids, mineralocorticoids, or both.
900
Explain autoagglutination. Why does this happen? How does this affect test results?
Autoagglutination is the spontaneous clumping of RBCs. The immune destruction of red cells causes them to clump together due to the antibody coatings sticking together. This can also form clots, causing a thrombosis.
May affect blood typing/crossmatch results
1000
This condition is caused by a 'defect' in the way a cat handles stress. Symptoms include hematuria, stranguria, inappropriate urination, urinary blockage, licking the urinary opening.
Feline Idiopathic Cystitis
The urinary bladder is lines with glycoproteins calls PSGAGs. This material insulated the bladder from the urine it contains. Urine can vary greatly in pH and can contain abrasive crystals in addition to assorted toxins and irritants that the kidneys have removed from the bloodstream and concentrated. All of these unpleasant materials are present in the urine, so it is a good thing to have a layer of insulation protecting the actual tissue of the bladder.
1000
Explain copper storage disease as you would to a client; what is copper storage disease? How is it diagnosed?
Excessive amounts of copper accumulate in the liver due to the inability to get rid of it, too much in the diet, or both.
It is diagnosed by a liver biopsy and copper quantification test.
