S.E of minocycline

A

a tetracycline (photosensitivity & dermatitis)

20
Q

Naproxen S.E

A

an NSAIDS (gastic ulcers and acute kidney injury)

21
Q

what is the virulent factor for Acute rheumatic fever

A

M protein & anti-n-acetyl-beta- D glucosamine cross react with CNS and Cardiac cells

22
Q

what type of hypersensitivity is acute rheumatic fever?

A

Type 2

23
Q

soap bubble lesion in the brain refers to what pathology

A

cryptococcus neorformins (latex agglutination test is more specific than india ink)

24
Q

headache , facial pain and black necrotic eschar on face what diseaze

A

rhizopus and mucor

25
Q

pressure equation

A

p= Q*R

26
Q

viscosity depends mostly on that?

A

Hematocrit

27
Q

3 things that increase viscosity

A

Polycythemia, Hereditary spherocystosis, hyperproteinemic state ( multiple myeloma)

28
Q

cause of dec viscosity

A

anemia

29
Q

resistance is directly proportional to

A

viscosity and vessel length and inversely proportional to radius to 4th power

30
Q

What vessel has the most TPR

A

Arterioles regulate capillary flow

31
Q

what group of people should you reduce the dose of digoxin or avoid it

A

Elderly due to decrease kidney functions (poor renal clearance)

32
Q

what s2 sound

A

aortic and pulmonary

33
Q

what sound is heard in early diastole

A

s3

34
Q

S3 is associated with what?

A

Dilated cardiomyopathy, CHF, normal in pregnant women nd children

35
Q

what heart sound is heard in late diastole

A

s4

36
Q

a wave

A

atrial contraction

37
Q

C wave

A

RV contraction

38
Q

x descent

A

atrial relaxation and downward displacement of closed tricuspid valve during ventricular contraction

39
Q

absent x decent is seen

A

tricuspid regurg

40
Q

v wave

A

inc RA pressure due to filling against a close tricuspid valve

41
Q

y descent

A

blood flow frm RA to RV

42
Q

what is the physiological reason for a split

A

anything that causes pulmonary valve to close later leads to a split

43
Q

in a normal split what valve closes first

A

aortic valve then pulmonary valve in S1

44
Q

where do you see wide splitting

A

seen in condition that delay RV emptying

Pulmonary stenosis and Right bundle branch block

45
Q

fixed spliting

A

ASD

46
Q

paradoxical splitting

A

anything that delay the left ventricle from emptying

aortic stenosis and left bundle branch block
