Q

what is a collapsing pulse aka corrigan’s pulse or water hammer pulse

A

it is when you raise the patient’s arm above their head
and feel their radial pulse

a high volume pulse rapidly hitting and then collapsing against the fingers can be felt

it is a sign of aortic regurgitation

Q

what is the JVP jugular venous P (vs carotid pulse)

A

column of blood extending backward from right atrium
indication of central venous P — increased CVP = increased JVP

decreases w inspiration

rises w hepatojugular reflux

height changes w angle of patient

Q

What is Buerger’s Test

A

process:
ask the patient to lie onto their side
slowly perform a straight leg raise —- wait for the point where the leg goes pale (ie guttering of the veins)
that angle between the leg and the horizontal = buerger’s angle

shallower angle = more severe peripheral vascular disease

Q

what is the trendelenburg/tourniquet test

A

process:
ask the patient to lie flat
perform a straight leg raise — put leg on my shoulder
stroke the veins towards the groin – expedite vein emptying
once empty = apply tourniquet to upper thigh
ask patient to stand
look for varicosities filling for 10-15s then release tourniquet

before releasing tourniquet
no filling of varicose V = isolated sapheno-femoral junction incompetence
slow filling of varicose V = mixed sapheno-femoral junction & perforating V incompetence

Q

where do you located the lower limb pulses

A

femoral: halfway between ASIS & pubic symphysis – below the inguinal ligament

popliteal: within popliteal fossa — between heads of gastrocnemius

posterior tibial: 2cm posterior & inferior to medial malleolus

dorsalis pedis:
draw line between medial & lateral malleolus — identify mid point
draw imaginary line from this mid point to 1st interdigital cleft
palpate along this line – just lateral to tendon of extensor hallucis longus
max: 1/3 distance down the line

Q

how do you interprete ABPI ankle-brachial pressure index

A

> 1.3: calcified vessel (non-compressable) — usually DM
1-1.3: normal
0.5-1: intermittent claudication
0.3-0.5: rest pain or critical limb ischaemia
<3: gangrene or ulceration

24
Q

compare & contrast arterial & venous ulcers

A

venous ulcer; arterial ulcer

Hx
V = varicose V, DVT
A = intermittent claudication, rest pain

classic sites
V = medial gaiter region
A = feet, toes, lateral malleolus (ankle)

edges
V = sloped
A = punched out

exudate
V = alot
A = little

pain
V = not severe
A = painful

oedema
V = common
A = uncommon

assoc features
V = venous eczema, haemosiderosis, lipodermatosclerosis, atrophie blanche
A = trophic changes, gangrene

Tx
V = graduated compression dressing, Abx for infection
A = endovascular revascularisation, surgical revascularisation

25
haemoptysis vs haematemesis vs nasopharyngeal bleeding
haemoptysis = coughing up blood (ie from respiratory tract) haematemesis = vomiting blood (ie from GIT) nasopharyngeal bleeding = bleeding nose preceded by haemoptysis = coughing haematemesis = N&V, dry retching contents haemoptysis = blood + sputum --- frothy haematemesis = blood + vomitus
26

28
DDx trachea displacement
towards side of lesion upper lobe collapse upper lobe cirrhosis pneumonectomy consolidation away from side of lesion pleural effusion tension pneumothorax
29
what is trachea tug
when the trachea seemingly moves inferiorly with each inspiration due to airflow obstruction --- causing gross overexpansion of chest usually sec to COPD
30
what is fremitus + DDx of increased/decreased fremitus
vocal fremitus = vibrations created by the vocal cords tactile fremitus = when those vibrations transmit to the chest wall DDx increased fremitus --- air in lungs replaced by liquid or solids lung consolidation haemothorax empyema cells decreased fremitus increased air in lungs = pneumothorax wall between lungs & chest wall = pleural effusion increased thickness of chest wall = obesity
31
what is Hoover's sign
indrawing of the lower ribs rather then expansion during inspiration due to an overinflated chest that cant expand laterally -- ie COPD
32
DDx bibasal crepitations
fine: pulmonary oedema interstitial lung disease coarse: bronchiectasis cystic fibrosis bibasal pneumonia
33
DDx pleural effusion
transudate (protein <30 g/L) LV failure vol overload hypoalbuminaemia Meig's syndrome exudate (protein >30 g/L) infection: pneumonia, TB infarction: PE inflammation: RA, SLE malignancy: bronchogenic, mesothelioma
34

flucloxacillin co-amoxiclav nitrofurantoin steroids sulphonylureas
35
what is GCS
it stands for glasgow coma scale it is a scale to describe the extend of impaired consciousness criteria ---- 1 point each eye opening --- max 4 spontaneous = 4 to sound = 3 to pain = 2 none = 1 verbal response --- max 5 orientated = 5 confused = 4 words only = 3 sounds only = 2 none = 1 motor response --- max 6 obeys commands = 6 localising = 5 normal flexion = 4 abnormal flexion = 3 extension = 2 none = 1 interpretation severe: 3-8 moderate: 9-12 mild/normal: 13-15

it is the left supraclavicular group
38
normal liver span + normal upper border of liver
normal liver span on physical exam: 12-15cm normal liver span on MRI female = 7-10cm male = 8-12cm
39
is suspect splenomegaly --- what additional actions can be done to rule it out
normal splenomegaly check: palpate from RIF to LUQ 2nd step: put left hand around the LUQ to push the spleen --- then do the same 3rd step: ask patient to tilt to their right --- then do the same
40
what are the complications of stomas
parastomal hernia: incisional hernia stoma stenosis: narrowing or constriction of the stoma or its lumen stoma necrosis stoma retraction: stoma recedes at least 0.5cm below the skin surface high output stoma: stoma output >1.5-2L over the last 24 hrs
41
what are the possible reasons for a loop/end ileostomy/colostomy/urostomy
loop ileostomy --- for defunctioning of the distal bowel obstruction -- eg. malignancy anus --- eg.

how do you differentiate inguinal & femoral hernia
inguinal = medial to pubic tubercle femoral = lateral to pubic tubercle + below inguinal ligament

general inspection: jaundice hands leuconychia -- sec to hypoalbuminaemia finger clubbing --- sec to cirrhosis palmar erythema asterixis --- if hepatic encephalopathy skin ecchymosis spider naevi chest gynaecomastia abdomen hepatosplenomegaly ascites
45
DDx guarding vs rigidity vs rebound tenderness
guarding: resistance to palpation due to contraction of abdominal muscles (ie can overcome w reassurance + gentleness) rigidity: constant involuntary reflex contraction of abdominal walls indication: peritoneal irritation or inflammation rebound tenderness: palpate the abdomen --- pain on rapid release of hand indication: peritonitis
46
DDx hepatomegaly
infective: viral hepatitis, EBV, CMV, HIV, malaria, abscess genetic: haemochromatosis, wilson's disease, alpha-1 antitrypsin deficiency infiltrative: sarcoidosis, amyloidosis hepatic: alcoholic liver disease w fatty infiltration, fatty liver biliary: PBC, PSC cancer congestion: RV failure, tricuspid regurg, budd chiari syndrome haematological: myeloproliferative disease, chronic leukaemia, lymphoma, haemolytic anaemia
47
DDx large left kidney vs splenomegaly
(left kidney; splenomegaly) palpable upper border (ie can get above) K: yes S: no palpable anterior notch K: no S: yes movement on inspiration K: inferiorly S: infero-medially on percussion K: resonant -- due to dilated loops of bowel anterior to it S: dull ballotable K: yes -- since retroperitoneal S: no --- unless gross ascites present
48
what is Courvoisier's law
enlarged gallbladder + jaundice = cancer of pancreas or obstruction to biliary tree >> gallstones
49
what is Murphy's sign
place hand on RUQ ask patient to take deep breath in when the inflamed GB presses on your hand -- patient would catch his breath indicates cholecystitis
50
DDx ascites
transudative (protein <30 g/L) CLD (75%) right HF vol overload hypoalbuminaemia constrictive pericarditis exudative (protein >30 g/L) infection: SBP, TB inflammation: pancreatiits malignancy
