• caused by an excess of on ear more adrenal steroids (most commonly cortisol)

Question 2

The physical exam findings suggest a sceptic process is under way due to the pyrexia (fever) note. Septic fever is commonly due to bacteria infections (True or false)

Answer 2

• True

Question 3

Physical exam findings also suggest involvement of the respiratory system. What is an increase respiratory rate indicative of?

Answer 3

• decreased ventilation and decreased diffusion
• cause lower PPO2 in blood therefore triggering chemoreceptors therefore increasing respiratory rate

Question 4

What are the main determinate of gas exchange in the lungs

Answer 4

• Driving partial pressure gradient, surface area available for diffusion, thickness of air-blood barrier, and physical properties of gas

Question 5

What could be cause decreased ventilation in this case?

Answer 5

• Poor air quality (dust particulate) in the barn mucus in the airways and inflammatory causing a loss of lung compliance

Question 6

TRUE/ FALSE: The chemoreceptors are located only in the brain & carotid artery

Answer 6

• False

Question 7

(TRUE/FALSE): The reason to give an antibiotic to help combat virus that is causing pneumonia

Answer 7

• False

Question 8

TRUE/FALSE: flunixin meglumine (banamine) is a non-steroidal anti-inflammatory drug that will help decrease the fever, make the heifer feel generally better and reduce the inflammatory in the airways

Answer 8

• True
