176-Hematology examination Examination steps (in general) 1-General appearance -pallor (anemia) -jaundice (hemolysis) -Rash on other parts -Bruising 2-Vital signs (pulse, blood pressure) 3-Hands -nails: spoon shaped, brittle nail, koilonychias (IDA) pale nail beds (anemia) -palmar crease (anemia) -joints (PIP, DIP, MCP, Wrist): swelling (RA, CTD) -purpura, petechial, ecchymosis 4-Arms -Epitrochlear LN -Axillary LN. 5-Face -eyes: pallor, jaundice, subconjunctival hemorrhage. -Mouth: glossitis, angular stomatitis, gum hypertrophy use tongue depressor for tonsils 6-Neck -Cervical LN+ supraclavicular LN -Bone tenderness: tap spine-àpress ribsàgently press sternum and clavicle 7-Chest and heart 8-Abdomen -palpate liver, spleen, kidney -DRE, genitalia -Inguinal LN -Para aortic LN 9-Legs -bruising, scratch marks. -Ulcers -neuro (B12 deficiency). 10-Others -fundoscopy -urine dipstick -temperature chart
CVS exam
WIPE
*position: patient lying in bed with enough pillow at 45 degree
2-General appearance
-dyspnea
-cyanosis
-oedema
-cachexia
3-Hands
I would like to have a look at your hands if you could bring them up in front of you please?
-clubbing.
-signs of infective endocarditis: (you do not have to mention them just say no signs of IE)
splinter hemorrhage
Osler’s node (red tender nodules on pulp of fingers)
janeway lesion (non tender erythema on palm)
-Exanthomata (optional)
-cyanosis
-pallor
4-Arms
pulse:
-rate
-rhythm
-radio radial delay (examiner will say no)
-radio femoral delay (examiner will say no)
*in the exam just check for 15 seconds and multiply by 4 . I think that either the examiner will give you the result straight away or there will be a stop watch inside to count 15 seconds.
Blood pressure: (examiner will give you the results in this case so you will not have to measure)
Estimate radial pulse
-feel: put the cuff on the right arm and feel the radial pulse. inflate it till the radial pulse disappear and increase 20 mm hg above then start deflating and when the radial pulse returns this is the SBP.
-Measure: with the stethoscope on the brachial artery of the right arm start inflating the cuff 20 mm hg above the previous SBP then start deflating every 3-4 mmhg and when the pulse appear this is the SBP, then continue deflating and when pulse disappear this is the DBP.
-Measure the BP of the left arm only with stethoscope
-Measure BP now with patient standing (only for postural hypotension):
>15 mm hg decrease in SBP
>10 mmhg decrease in DBP
5-Face
-eyes (pallor, jaundice, exanthelasma) I am gonna pull down your lower eyelids
-malar flush
-mouth (central cyanosis). Can you open your mouth for me? And For central cyanosis ask Can you lift your tongue to the roof of the mouth?
6-Neck
-feel the carotid pulse (one artery per time; not two carotid together)
-measure JVP: >3 cm increase JVP. Ask patient to turn his head to left.
-hepatojugular reflux: press on tummy for 10 sec. ask if any tummy pain before you press.
7-Heart examination
inspection
-scars (median sternotomy, lateral thoracotomy) ask patient to lift arm to look for lat. Scars.
-deformity
-visible pulsation
-pacemakers
Palpation
-apex beat (5th intercostal space mid clavicular line 1 cm medial and below the nipple) heel off
-heave: left sternal edge fingers off
-thrills (palpable murmurs): 3 positions: apex beat, left sternal edge, upper chest
Auscultation
-bell on apex
-diaphragm on apex
-diaphragm on tricuspid area (5h intercostal space left sternal edge)
-diaphragm on pulmonary area (2nd intercostal space left sternal edge)
-diaphragm on aortic area (2nd intercostal space right sternal edge)
-axilla (radiation of systolic murmur of MR)
-right neck (radiation of systolic murmur of AS) + carotid bruit.
-left neck (carotid bruit) as patient to hold breath during listening of carotid bruit.
-lean forward for AR
-Left side turn for MS
Notes
bell=low pitch sounds= S3 or diastolic murmur
diaphragm=high pitch sounds=S1, S2, S4, systolic murmur
S1 à loud=MS/ soft=MR
S2à loud=AS/ soft = AR
P2à loud= pulmonary hypertension

percussion: ascites
auscultation (aortic and renal bruit only in HPT)
10-legs (no need in this case)
inspection: color and swelling
palpation,: tenderness, oedema, hot, pulses
11-office tests (if you have time)
-urine dipstick
-fundoscopy
-ECG
Explanation.
-I have examined you very carefully but I could not find any murmur. I reassure you that it was completely normal cvs exam. Maybe at that time, you might have some fever or illness; sometime we can find some temporary murmurs during illnesses because of increased blood flow and work of the heart. We call it physiological murmur, which I think it was the most likely in your case.
-For more reassurance, I can do ECG to read your heart.
-Are u with me so far? Any questions?
Hypertension exam
1-WIPE 2-General appearance -cyanosis , dyspnea, Oedema -weight 3-Hands -cyanosis, clubbing, pallor -nail changes 4-Arm Pulse -rate and rhythm -radio radial delay -radio femoral delay with permission (coarctation of aorta) Blood pressure -make sure cuff size is correct -position patient correctly (elbow at heart level, lying) -take the SBP on one arm by palpation method -take the BP same arm by auscultation method both SBP & DBP -then take by auscultation the BP on the other arm (difference between the arms of >10 mmhg suggest vascular disease). -take the BP in standing (ask permission first) to look for any postural changes). Note/ the examiner will not let you do all the steps usually after measuring one arm the will give you the other arm and the postural one) 5-Face -eye (pallor and jaundice) -malar flush -mouth (central cyanosis) -cushinoid facies (moonface, plethora, acne) -eye puffiness, sallow skin (kidney px) -verilisation (pcos). 6-Neck -JVP -carotid artery palpation be careful one at a time not both together -Thyroids 7-Heart inspection -scar, deformity, visible pulsation) palpation -apex beat -heave and thrill auscultation -heart sounds and murmurs Mitralà tricuspidàpulmonaryà aorta -radiation axillaà neck -carotid bruit (breath in and out then hold) 8-Back inspection (oedema) palpation (sacral oedema) percussion (upper and lower lobe) auscultation (basal crackles). 9-Abdomen Inspection (distension, visible bruit) palpation -liver -kidney -abdominal aorta auscultation (diaphragm) -aorta and renal bruit -AORTIC BRUIT - 2.5cm above the umbilicus -RIGHT AND LEFT RENAL BRUIT 2.5 cm beside Aorta 10-leg -pulses -oedema tenderness 11-others -fundoscopy (showed AV nipping and silver wiring – said its grade 2 Hypertensive eye changes) (other case with papilledema and grade 4 hypertension) -UDT -ECG Explain even though your BP normal now , u have hypertensive eye changes which means ur having poorly controlled long standing high blood pressure Differential diagnosis EAR M -Endocrine (Cushing, conn, acromegaly, thyroid, pheochromcytoma) -arteries (Coarctation of aorta, Aortic Stenosis) -Renal (renal artery stenosis, polycystic kidney, DM) -Medications (NSAIDS, OCP)
