  5. assess characteristics of liver edge
55
Q

what characteristics of the liver edge should be assessed?

A
  1. degree of extension below the costal margin (if greater than 2cm this suggests hepatomegaly)
  2. consistency of the liver edge (nodular consistency suggests cirrhosis)
  3. tenderness (may suggest hepatitis or cholecystitis)
  4. pulsatility (associated with tricuspid regurgitation)
56
Q

what is Courvoisier’s law?

A

states that in the presence of a palpable gallbladder, jaundice is not likely to be due to gallstones

57
Q

58
Q

how is the gallbladder palpated?

A
  1. usually not palpable
  2. if it is palpable, it suggests enlargement secondary to biliary flow obstruction/infection
  3. palpate at the right costal margin, in the midclavicular line (tip of 9th rib)
  4. if enlarged, a well-defined round mass that moves with respiration may be noted
59
Q

what is Murphy’s sign? how is it elicited?

A
  1. position your fingers at the right costal margin in the mid-clavicular line at the liver’s edge
  2. ask the patient to take a deep breath
  3. if the patient suddenly stops mid-breath due to pain, this suggests cholecystitis (positive pain)
60
Q

how is the spleen palpated?

A
  1. begin palpation in the RIF, starting at the edge of the SIS, using the flat edge of your hand
  2. ask patient to take a deep breath and as they begin, palpate the abdomen with your fingers aligned with left costal margin
  3. feel for a step as the splenic edge passes below your hand during inspiration
  4. repeat this process of palpation moving 1-2cm superiorly from the RIF each time towards the left costal margin
  5. as you advance toward the left costal margin using your right hand to palpate for splenomegaly, place your left hand posteriorly and roll the patient slightly toward you
61
Q

when does splenomegaly become palpable?

A

once the spleen has enlarged to 2-3 times its normal size

62
Q

what are causes of splenomegaly?

A
  • portal hypertension secondary to liver cirrhosis
  • haemolytic anaemia
  • congestive heart failure
  • splenic metastases
  • glandular fever
63
Q

how do you ballot the kidneys?

A
  1. anterior hand should press deeply, lateral to the margin of the rectus muscle in the upper quadrant
  2. posterior hand placed in costovertebral (renal) angle and should be used to lift the kidney up against the anterior hand
  3. place your left hand behind the patient’s back, below the ribs and underneath the right flank
  4. place your right hand on the anterior abdominal wall just below the right costal margin in the right flank
  5. push your fingers together, pressing upwards with your left hand and downwards with your right
  6. if kidney is ballotable, describe its size and consistency
  7. repeat process on other side
64
Q

how can you distinguish a palpable kidney from a spleen?

A

attempt to insert your hand between the upper pole of the kidney and the costal margin, which can be done if the mass is renal but not if it’s the spleen; the spleen has a notch which may be palpable; the spleen is not balloteable

65
Q

what are causes of bilaterally enlarged ballotable kidneys?

A

PKD or amyloidosis

66
Q

what are causes of a unilaterally enlarged ballotable kidneys?

A

renal tumour

67
Q

how can you palpate the aorta?

A
  1. using both hands, perform deep palpation just superior to the umbilicus in the midline
  2. in healthy people, your hands should begin to move superiorly with each pulsation
  3. if your hands move outwards, it suggests the presence of an expansile mass e.g. AAA
68
Q

how can you palpate the bladder?

A
  1. before doing this, allow patient to go to the toilet
  2. warn the patient that palpation may be uncomfortable and bring a sudden urge to urinate
  3. a distended bladder can be palpated in the suprapubic area arising from behind the pubic symphysis
  4. in healthy people, it’s not palpable
69
Q

where can a distended bladder be palpated?

A

in the suprapubic area arising from behind the pubic symphysis; it will be impossible to feel the lower border of the mass behind the pubis

70
Q

what structures should be percussed?

A
  1. liver
  2. spleen
  3. bladder
  4. assess shifting dullness
71
Q

how can you percuss the liver?

A
  1. percuss upwards of 1-2cm at a time from the RIF towards the right costal margin until it changes from resonant to dull (indicates the lower liver border)
  2. continue to percuss upwards 1-2cm at a time until the note changes from dull to resonant indicating the upper border
  3. determine its size
  4. consider normal surface markings of superior liver border (6th rib in midinspiration)
72
Q

how can you percuss the spleen?

A
  1. percuss upwards 1-2cm at a time from the RIF towards the left costal margin until the note changes from resonant to dull
  2. percuss the area of the lowest intercostal space in the left anterior axillary line
  3. if note changes from resonant to dull on full inspiration, the Castell sign is positive
73
Q

how can you percuss the bladder?

A
  1. percuss downwards in the midline from the umbilical region towards the pubic symphysis
  2. a distended bladder will be dull to percussion, allowing you to approximate its border
74
Q

how can you assess the presence of ascites?

A

percussion can identify it by assessing shifting dullness

75
Q

how can you assess shifting dullness?

A
  1. percuss from the umbilical region to the patient’s left flank; if dullness is noted, this may suggest presence of ascites
  2. whilst keeping your fingers over the area at which the percussion note became dull, ask patient to roll onto their right side (towards you for stability)
  3. keep the patient on their right side for 30 seconds and then repeat percussion over the same area
  4. if ascites is present, the area that was previously dull should now be resonant (dullness has shifted)
76
Q

what structures should be auscultated?

A
  1. assess bowel sounds

2. listen for bruits

77
Q

how can you assess bowel sounds?

A
  1. auscultate over at least 2 positions on the abdomen

2. to be able to say a patient has absent bowel sounds you need to auscultate for at least 3 minutes

78
Q

what types of bowel sounds?

A
  • normal: gurgling
  • tinkling: associated with bowel obstruction
  • absent: suggests ileus
79
Q

how can you auscultate for bruits? where do you listen for different types of bruits?
