normal

27
Q

- decreased active and passive movements

28
Q

intention tremor is a symptom of…

A

cerebellar degeneration

29

A

anti-muscarinic poisoning

34
Q

A

ADPKD

36
Q

A

2-6 cm above the carina

37
Q

A

mild viral illness

38
Q

What is the second most common cause of primary adrenal insufficiency (after autoimmune - addisons disease)

A

infectious adrenalitis

39
Q

Someone with a severe asthma attack has a normal pCO2, is this good or bad?

A

It’s bad, the body should respond by hyperventiliation leading to decreased CO2 and alkalosis. Normal PH or CO2 indicates muscle fatigue and impending respiratoyr collapse
