Q

what is the ABCD checklist for skin cancer screening?

A

Asymmetry
Border
Color
Diameter

18
Q

when do the ABCDs for skin cancer raise suspicion?

A

asymmetry: when bisected, one half of the lesion is not identical to the other half
border: the border is uneven or ragged as opposed to smooth and straight
color: the lesion is more than one shade of pigment
diameter: is greater than 6mm

presence of one or more of these elements raises suspicion that lesion is cancerous

19
Q

what else are we inspecting?

A

umbilicus in midline
shape (should be flat, distention)
movement (should move with respiration, pulsations are abnormal)

20
Q

what can be the problem if the abdomen is distended?

A

small bowel obstruction, enlarged spleen or liver, AAA

21
Q

when should auscultation be done?

A

prior to percussion and palpation because bowel sounds may chance with manipulation

22
Q

what are normal bowel sounds?

A

5-30/min

23
Q

what is a hypoactive bowel?

A

4/min or less communicate with the physician

24
Q

what is a hyperactive bowel?

A

30 or more/min rush of symptoms with abdominal cramping communicate with physician

25
Q

what is the procedure for auscultation of bowel sounds?

A

place diaphragm of stethoscope lightly on abdomen in RUQ
listen for bowel sounds (low pitched gurgling sounds)
repeat with other quadrants (most prevalent in RLQ)

26
Q

what is bruits?

A

unusual sound that blood makes when it rushes past obstruction
abnormal
indicative or arterial disorder (stenosis, aneurysm)

27
Q

what is the procedures for auscultation of bruits?

A

place bell of stethoscope over artery (abdominal artery, renal artery, iliac artery, can be assessed in carotid artery as well) if present document and call physician

28
Q

why is percussion used?

A

to identify potential abnormal anatomy (abdominal mass) or as a provocative test (kidneys)

29
Q

if the sound heard from percussion is tympanic what does this mean?

A

air filled structure
normally present over most of the abdomen in supine

30
Q

if the sound heard from percussion is dull what does this mean?

A

if in that area should be tympanic-> possible underlying abdominal mass

31
Q

what is the procedure for percussion?

A

hyperextend your middle finger of non-dominant hand and place the distal interphalangeal joint firmly against the patient’s abdomen (Avoid contact with other part of your hand)
with the end of the opposite middle finger, use a quick flick of the wrist to strike the middle finger

32
Q

what is the procedure for percussion of the liver?

A

start percussion in the right mid clavicular line just above the umbilicus (you should hear tympany of the bowel)
continue upward until you hear your first dull sound (this is the inferior border of the liver, you can note this location with a skin marker or have the patient mark with a finger)
continue along this same path until you hear a new sound. this should be the resonant sound of the lungs (this is the superior border of the liver, you can note this location with a skin marker or patient finger)
the distance between the two point should be between 6-12cm (if >12 cm possible enlarged liver or lung mass)

33
Q

what is the procedure for skin percussion?

A

start percussion at the lowest intercostal space along the left anterior axillary line (this area is normally tympanic)
ask the patient to take a deep breath and percuss this area again (dullness in this area is a sign of splenic enlargement)

34
Q

why do we do kidney (Murphy’s) percussion?

A

patients with kidney disease may complain of pain over the costovertebral angle with referral to the iliac crest
pain is often unchanging with assumption of a different position and movement

35
Q

what is the procedure for kidney percussion?

A

patient sitting on exam table
use heel of closed fist to strike patient over costovertebral angles
perform bilaterally and compare

36
Q

what is the procedure for palpation?

A

broad hand contact (reduces ticklishness)
circular fashion
start superficial (if no complaint of tenderness or palpable mass, use deeper pressure)
areas of tenderness should be noted, especially if: associated with other symptoms, local mass, muscle guarding, or referral of pain/reproduction of symptoms)

37
Q

what does local abdominal pain with tenderness on palpation and muscle guarding indicate?

A

peritoneal inflammation

38
Q

what is rebound tenderness useful for?

A

appendicitis

39
Q

what is the procedure for rebound tenderness?

A

locate McBurney’s point (2/3 distance from umbilicus to ASIS)
press deeply on abdomen with hand
after a moment, quickly release the pressure
if it hurts more when you release the patient had rebound tenderness

40
Q

what is an AAA (abdominal aorta aneurysm)?

A

abnormal widening of blood vessel (>3cm in diameter)
weakening of medial-middle “layer” of blood vessel
approximately 75% of aneurysms occur in abdominal aorta

41
Q

what is the procedure for palpating for an AAA?

A

patient supine with hips and knees flexed
locate abdominal aorta pulse (0=absent, 2+= normal, 4+ bounding)
press down deeply in the midline above the umbilicus
the aortic pulsation is easily felt on most individuals
a well defined pulsatile mass, greater than 3cm across, suggests an aortic aneurysm

42
Q

what is the procedure for measuring AAA?

A

locate the abdominal aorta pulse which is just left of midline superior to umbilicus
once a pulse has been detected with midabdominal palpation, place both index fingers with deep but gentle pressure, along the sides of the pulse noting the presence of a laterally expansive pulsation >3cm across
such a finding would warrant abdominal auscultation for the presence of a bruit
