PCM II Midterm Flashcards
(126 cards)
visceral pain
cause: stimulation of visceral pain fiber
- secondary to organ involvement
- felt at midline of structure involved
- NOT LOCALIZED
parietal (somatic) pain
cause: stimulation of somatic pain fibers
- secondary to inflammation in parietal peritoneum
- constant and more severe that visceral pain
- LOCALIZED
- aggravted by movement or coughing
referred pain
problem originates within the abdomen but the pain is felt at distant sites which are innervated at the same spinal level as the disordered structure
general vs focused ROS
general: same every time; based on discriminators and life threats
focused: based on CC (with abdominal pain review GI, GU, GYN)
what are some additional social questions pertinent to CC of abdominal pain (besides drugs, tobacco, alcohol)
stress
travel
well water
ingestion of undercooked meats
Order of the PE for an abdominal exam
- drape the patient
1. inspect
2. auscultation
3. percussion
4. palpation
what are the landmarks of the abdomen
- sternal xiphoid process
- costal margins
- umbilicus
- ASIS
what abdominal organs are located in the epigastric area
pancreas
liver
gallbladder
stomach
what is normal bowel sounds numerical classification
5-34 clicks, gurgles/minute
numerical dx for absent bowel sounds and possible causes
no sounds for greater than 2 minutes
-chronic intestinal obstruction, intestinal perforation, mesenteric ischemia
numerical classification for decreased bowel sounds and possible causes
none for 1 minute
-post-surgical ileus, peritonitis
(post surgical ileus is malfunction of intestinal motility following an abdominal surgery)
numerical classification and possible causes of increased bowel sounds
greater than 34 per minute
-diarrhea, early bowel obstruction
(***remember late bowel obstruction caused absent sounds)
Abdominal auscultation: tinkling sound like raindrops on metal
high pitched bowel sounds
-sign of early intestinal obstruction
Abdominal auscultation: vascular sounds resembling a heart murmur over abdominal arteriole vasculature
bruits
-sign of vascular obstruction
Abdominal auscultation: grating sounds with respiratory variation
friction rub
- sign of visceral peritonitis
- *listen over liver and spleen
Abdominal auscultation: soft humming noise
venous hum
- sign of increased collateral circulation between portal and systemic venous systems (portal HTN)
- *listen over epigastric and umbilical regions
abdominal percussion: describe tympany vs dullness vs resonance vs hyper-resonance
which sound is the major sound of the abdominal viscera and GI tract
tympany: high pitched; air filled
dullness: non-resonating; solid organ/mass
resonance: hollow organs (lungs)
hyper-resonance: air filled hollow organ (pneumothorax of lungs)
- tympany predominates - bc of gas in GI tract
- *BUT scattered areas of dullness is normal from fluid and feces
abnormal abdominal percussion findings
Normal: tympany with scattered small areas of dullness
- large dull areas from a mass or enlarged organ
- protuberant (budging) abdomen with tympanitic sounds throughout may indicate an intestinal obstruction
how to palpate the abdomen
with the palmer aspect of the hand and fingers together, gently palpate all 4 quadrants, then deeply palpate all 4 quadrants
*always start farthest from the tender area
how to assess spleen with percussion? how would splenomegaly present?
- start from cardiac border at left anterior axillary line and percuss laterally
- tympany found here = unlikely splenomegaly
- dullness found here = splenomegaly
how to asses the liver with percussion? what are abnormal findings?
- start in RLQ, percuss midclavicular line and up until sound changes from tympany to dull (lower border)
- in RUQ, percuss midclavicular line and down until sound changes from lung resonance to dull (upper border)
- normal vertical span: 6-12cm
- increased: hepatomegaly from cirrhosis, lymphoma, hepatitis, right-sided heart failure, amyloidosis, hemochromatosis
- decreased: shrunken liver from cirrhosis
how to asses the liver via palpation? abnormal findings?
-left hand behind pt supporting 11th and 12th ribs pressing anteriorly, right hand on pt right abdomen pushing posterioly, ask pt to take deep breath and feel the liver edges as it comes down to meet your right hand
normal liver: slight tender, soft, smooth surface
abnormal: irregular edge/nodules (from hepatoceullar carcinoma) or firmness/hardness (from cirrhosis, hematochromatosis, amyloidosis, lymphoma
how to assess spleen with palpation? abnormal findings?
- noramlly not palpable unless enlarged
- when enlarged it protrudes anterior, inferior, and medially
-reach over pt and posteriorly grasp pt LUQ with left hand, place right hand below left costal margin and press posteriorly. ask pt to breath and feel for spleen as it comes down to meet your LEFT hand.
- in 5% of normal adults, tip will be palpated
- tip is palpated in those with low/flat diaphragm like COPD
causes of splenomegaly
portal HTN , blood malignancies, HIV, splenic infarct, hematoma, mononucleosis
