Q

Parvo:

How does parvo act on the villi of the intestine?

A
  • Virus infects the intestinal crypts of the epithelial cells where new enterocytes are made.
  • This interferes with normal epithelial cell growth and development because the new enterocytes will not be efficiently or effectively made.
  • Villi will be shortened

Q

Parvo:
Nursing Intervention: GI Rest
-describe
-pathology it reverses

A
  • Designed to allow intestinal tract to rest and begin healing process by growing new epithelial cells
  • NPO until no V for 24hrs
  • Followed by reintroduction of water, then very small amounts of highly palatable food until daily requirement is being fed over 2-3 feedings
22
Q

Parvo:
Nursing Intervention: Antibiotic therapy
-description
-pathology to reverse

A
  • Leukopenia likely means P won’t be able to mount a response to transmigrating bacteria
  • Hemorrhagic diarrhea likely means intestinal mucosal integrity is breached, making bacterial transmigration more likely
  • Antibiotics given as preventive measure to prevent normal GI bacteria from entering into systemic circulation
23
Q

Pancreatitis:

What are the 2 exocrine functions of the pancreas?

A

To provide digestive enzymes to the intestinal tract for the digestion of oral nutrients; to provide bicarbonate to neutralize the acidic nature of the fluid that arrives in the duodenum from the stomach

24
Q

Pancreatitis:

What cells make up the exocrine pancreas?

A

Acinar cells

Ductal cells

25
Q

Pancreatitis:

What is autodigestion?

A

when digestive enzymes become activated within the pancreatic tissue and begin destroying the various pancreatic cells

26
Q

Pancreatitis:

What are the inflammatory consequences of autodigestion?

A
  • body sends more inflammatory mediators, increasing swelling and edema
  • this potentiates the release of additional active digestive enzymes destroying more pancreatic tissue
  • swelling may extend to surrounding organs and impinge on common bile duct
  • pancreatic necrosis if severe
27
Q

Pancreatitis:

What causes vomiting/nausea in acute pancreatitis

A

The inflammation in the pancreas activates certain receptors in the pancreas which stimulate the vomiting center within the brain; remains as long as inflammation and pancreatic swelling are present

28
Q

Pancreatitis:

What does acute pancreatitis look like in cats?

A
  • sudden onset of anorexia +/- nausea
  • weight loss due to anorexia
  • depression/lethargy
29
Q

Pancreatitis:

What is the cephalic component of the digestive process?

A

It reacts to the smell of food and tells the stomach, SI, and pancreas to begin prep for food by releasing some of their enzymes, thus stimulating the same enzymes that are causing all the inflammation in the first place

30
Q

Pancreatitis:

Name 2 potential complicating disorders that may occur with acute pancreatitis

A 
Pulmonary Thromboembolism (PTE)
Pancreatic "Sterile" Abscess
31
Q

Pancreatitis:

What is a pancreatic sterile abscess? How does it occur?

A

Occurs as a result of body attempting to contain inflammation, dead cells, and debris that have been occurring within the pancreatic tissues;
made up of dead neutrophils, dead cells of the affect tissue, and debris

32
Q

41
Q

Spinal Cord Disorders:
Withdrawal Reflex
-nerve
-spinal cord segments

A

Sciatic nerve

L6-S1; sometimes S2

42
Q

Respiratory Dz Overview:

Explain the purpose of the cough reflex and how it works

A

an irritant stimulates nervous impulses –> impulses are sent to brain –> triggers a sudden inspiration of air, closure of epiglottis, and forceful contraction of the abdominal and expiratory muscles –> when vocal cords and epiglottis suddenly open, air within lungs is forcefully expelled outward –> foreign particles are expelled with it

43
Q

Respiratory Dz Overview:

What is the underlying physiology of bronchoconstriction?

A

Parasympathetic nerves get activated via inflammatory Dz or via reflexes stimulated by the presence of irritants on the epithelial surfaces –> nerves release acetylcholine –> this causes small muscles around the bronchioles to constrict

44
Q

Respiratory Dz Overview:

How does pneumonia result in a productive cough?

A

Remember, inflammation leads to increased permeability of membranes, including membranes that line the alveoli. This allows fluid to leak into the alveoli, which inhibits the flow of air into the alveolar space;

Alveoli continue to fill with fluid and debris and regions of the lung tissue become consolidated and can’t fill with air. Accumulation of material = productive cough

45
Q

Infectious Tracheobronchitis:

List 2 types of vaccines available for Bordetella and what they stimulate

A

avirulent live- local IgA

whole cell bacterins- systemic

46
Q

Pulmonary Edema:

How is a “dry” alveolus maintained?

A

Interaction between pulmonary circulation and pulmonary lymphatic system maintains a slight negative pressure in the pulmonary interstitium (space between the cells and alveolar wall) –> this acts as a vacuum to suck any fluid that leaks into the alveolar space out of the alveoli –> extra fluid carried away via lymphatic vessels or absorbed by blood vessels

47
Q

Pulmonary Edema:

Common clinical signs of Pulmonary Edema (list them)

A

Dyspnea w/ Tachypnea & Increased Respiratory Effort
Exercise Intolerance
Crackling Sounds
+/- Cough

48
Q

Pulmonary Edema:

If a cough happens to be present with pulmonary edema, what does it sound like?

A

moist sounding cough, but mostly non-productive

49
Q

Pulmonary Edema:

What medication can be used with pulmonary edema? How does it work?

A

Furosemide
decreases the overall blood volume which decreases the pressure within the circulatory system –> allows for movement of fluid accumulating within the alveoli to travel back in to the circulatory system

50
Q

Feline Asthma:

What antibody is involved in feline allergic lung Dz? Where is it produced?

A

IgE

Produced – cells of skin, intestine, and lungs

51
Q

Feline Asthma:

What do the inflammatory cells do to the body in the case of feline asthma?

A
  • inflammatory cells stimulate contraction of smooth muscles around bronchioles to try and stop the inhaled allergen from moving deeper in the airway
  • mucous production is stimulated to try and trap the allergen
  • inflammatory cells may also congregate around airway and spill into bronchiole or alveolar lumen
  • Result = turbulent air flow and decreased air flow thru airways
52
Q

Feline Asthma:

What two types of drugs are used for feline asthma? What do they do to help Tx the clinical signs?

A
  • Bronchodilators increases airway diameter and improves air flow
  • Glucocorticoids reduce inflammation
