Q

osmolar gap

A

gap=measured- calculated

normal=0-10

cal=2(Na)+ BUN/2.8 + glucose/18 + etOH/5

27
Q

causes of osmolar gap

A 
isopropyl 
methanol
ethylene glycol
glycerol
mannitol
28
Q

metabolic acodoisis with anion gap shown by which alcohols

A

all MA

only meth and isopropyl show anoin gap

29
Q

which vitamin given in methanol toxicity

A

folate

30
Q

which vitamin given in ethylene glycol toxicity

A

thiamine

pyridoxine

31
Q

route of methanol toxicity

A

ingestion
inhalation
skin

32
Q

CO poisoning cam be confused with

A

hypoglycemia

flu during winter time

33
Q

pO2 in CO poisoning

A

normal because it is the pressure as gas form

not bound to Hb

34
Q

what does routine pulse oximetry show in CO poisoning?

A

normal

so CO pulse oximetry should be used(initial diagnostic test)

35
Q

can naloxone be given in opiate toxicity

A

yes

withdrawal is uncomfortable but not fatal

36
Q

why the use of flumenezil is controversial in BDZ toxicitu

A
  1. in chronic users may ppt withdrawal and seizures.

2. if used for medical condition may exaberate condition

37
Q

hallucinogen intoxication tt

A

BZD

38
Q

hallucinogens

A 
marijuana
mescaline
LSD
peyote
psilocyben
phencyclidine(PCP/angel dust)
39
Q

diagnosis of lead poisoning

A

blood lead levels

<10 ug /dL acceptable

40
Q

microcytic anemia and abdominal pain

which heavy metal poisoning?

A

Pb

41
Q

Tt of lead poisoning

A

EDTA
dimercaprol(BAL)
pencillamine

succimer(ORAL)

42
Q

potential precipitants of lithium toxicity

A

diuretics
ACEi
NSAIDS

43
Q

cause of hyperventilation in aspirin

A
  1. central stimulation

2. compensatory mech to Metabolic acidosis

44
Q

what is the ph in aspirin toxicity

A

variable

45
Q

special feature of aspirin tox

A

tinnitus

46
Q

toxicity of TCAs is due to

A

anticholinergic

Na channel blocking affect

47
Q

ECG changes in TCA toxicity

A

widening of QRS complex

48
Q

any sign of cardiac toxicity in TCAs should lead to imediate use of

A

bicarbonate
cardioprotective

not for excretion purposes

49
Q

features of WE and KP in alcoholism

A

WE
confusion
ataxia
nystagamus

KP
amnesia
confabulations

50
Q

mainstay of diagnosis of head injury

A

CT scan(plain …not contrast , no skull Xray )

cervical spine xray

51
Q

diagnosis of concussion

A

history of loss of conciousness

and negative CT findings

52
Q

why is slight htn maintained during head injury?

A

SBP=110-160

so than CPP is normal since ICP has risen which can decrease CPP leading to ischemia

it should not be much high so as to cause bleeding

53
Q

if initial CT is normal..still SAH is suspected then?

A

lumber puncture

diagnostic for SAH

54
Q

xanthochromia needs how much time to form

A

4 to 6 hrs

its presense is indicative of SAH

RBCs in CSF can be due to traumatic needle entry also

55
Q

xanthochromia needs how much time to form

A

4 to 6 hrs

its presense is indicative of SAH

RBCs in CSF can be due to traumatic needle entry also

56
Q

parkland formula

A

4 × kg × burnt percentage

give half in first 8 hrs
next half in next 16 hrs

57
Q

osborne wave /J wave

A

characteristic of hypothermia

elevation of J point

58
Q

sensitivity of blood cells to radiations

A

lympho>neutro………>RBC (least)

59
Q

hypothermia is one of the few times in which a patuent can be resuscitated from pulselessness beyond the usual 10 minutes of efforts

A

yes

60
Q

org in cat bite
