Q
mechanism, sx, dx, and tx for the following:
1 anterior shoulder dislocation
2 posterior shoulder dislocation
3 clavicular fx
4 scaphoid fx
A

1 - strain on the glenohumoral joint, arm held to side externally rotated, xray then MRI (must rule out axillary artery and nerve injury), shoulder relocation and immobilization

2 - seizure or electrical burn, arm is medially rotated at side, xray then mri, traction and surgery is pulses or senses are diminished

3 - trauma, pain over location, xray is best test (must rule out subclavian artery/brachial plexus injury), simple arm sling

4 - FOOSH, pain at anatomical snuffbox, xray wont show for 3 weeks so clinical suspicion!, thumb spica cast

Q

aortic dissection

A

false lumen in the intima of the aorta

sudden onset tearing chest pain radiating to back + asymmetric arm blood pressures

dx is done with TEE if unstable (fastest) or MRA (best) if patient is stable

tx ascending with surgery and BP control
tx for descending is BP control (BB)

28
Q
post op fevers
POD 1-2
POD 3-5
POD 5-7
POD 7
POD 8-15
A
1-2 wind (atelectasis or pna)
3-5 water (uti)
5-7 walking (dvt/pe)
7 wound (wound ifx or cellulitis)
8-15 weird (drug fever or deep abscess)
29
Q

mc finding for PE on ekg

A

nonspecfic ST changes

s1-q3-t3 is NOT the most common change seen

30
Q

tx for PE

A

heparin to coumadin bridge

if PE while on coumadin therapy, place an IVC

31
Q

old woman s/p total hip replacement 3 days ago now has 30 min of SOB and chest pain…..what do you do?

A

order EKG and spiral ct scan

if patient had an allergy to contrast, get a VQ scan instead of spiral ct

32
Q

noncon ct for…

contrast ct for…

A

noncon for trauma and bleeding

contrast for infection and cancer/mass lesions

33
Q

can youuse metforman with contrast study?

A

no, stop med proior to scan

34
Q

Charcoal is good for

A

Any ingestion

Can’t hurt and Is better than lavage

35
Q

What is the treatment for acetaminophen overdose that was more than 24 hours ago

A

No therapy needed

36
Q

What is next step if clearly toxic amount of acetaminophen was ingested(more than 8-10 g)?

A

N -acetylcysteine

37
Q

What symptoms do you see with aspirin overdose and what is the treatment

A

Tinnitus and hyperventilation leading to respiratory alkalosis and metabolic acidosis from lactate

Treatment is alkalinizing the urine which increases the rate of aspirin excretion

38
Q

Treatment of TCA overdose

A

Sodium bicarbonate is cardioprotective but does not increase TCA excretion

39
Q

What Will blood gas show for carbon monoxide poisoning?

A

Normal pO2 because oxygen does not detach from hgb

Lactic aciddosis develops

40
Q

What is the best diagnostic test for carbon monoxide poisoning

A

Routine oximetry will be falsely normal so the best and accurate test is carboxyhemoglobin level

41
Q

How do you differentiate carbon monoxide and methemoglobinenia on exam

A

Blood is red with carbon monoxide and brown with methemoglobinemia

42
Q

Treatment for methemoglobinemia

A

Methylene blue

43
Q

Treatment for carbon monoxide poisoning

A

Hyperbaric oxygen for severe disease or just 100% oxygen

44
Q

Cyanosis plus normal PO2 =

A

Methemoglobinemia

45
Q

Treatment for organophosphate poisoning or or nerve gas

A

Atropine

46
Q

What EKG abnormality will digoxin overdose show

A

Downsloping st segments
And
Hyperkalemia

47
Q

Treatment for digoxin overdose

A

Digoxin specific antibodies

48
Q

Treatment for lead poisoning

A

Chelating agent’s to remove the blood from the body like succimer or EDTA or dimercaprol

49
Q

Everyone with Mobitz two 2nd° AV block which is dropped Beats without progressive lengthening of PR interval
Gets what…

A

They get a pacemaker even if they are asymptomatic

50
Q

Next step if a patient is bradycardic and asymptomatic

Then once rate is controlled give warfarin or ruvaroxaban to anticoagulate

54
Q

Hemodynamically unstable atrial arrhythmias are managed with…

A

Synchronized cardioversion

55
Q

Differences between methanol and Ethylene glycol poisoning

A

Both are treated with fomepizole and dialysis

Methanol presence with Eye toxicity and retinal inflammation and as the lingo I call presents with renal toxicity and envelope shaped crystals made of oxalate
