DL: Thyroid and hypoadrenocorticoid disorders

Question 1

T/F: without tachycardia, an animal with a murmur is unlikely to be in heart failure

Answer 1

True - unlikely to have SNS if not tachycardic so unlikely to be in HF

Question 2

Question 3

Is a blood glucose of 23.5 (ref 3.3-7) likely d/t stress?

hepatic necrosis and cell death
