PCM II Midterm Flashcards
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
what are the special test for ascites? abnormal findings that indicate a positive test for ascites?
- shifting dullness test
- percuss tympanic and dullness border with pt supine, then again with pt lateral recumbent
- normal (-) = borders are same
- abnormal (+) = dullness shifts to dependent side and tympany shifts to top - test for a fluid wave
- have pt place hands over chest, ask assistant to place ulnar aspect of hand midline, you tap on one flank sharply with finger tips
- normal (-) = no impulse transmission
- abnormal (+)- transmission of impulse to contralateral flank
special tests for appendicitis
- mcburneys point (2/3 way between umbilicus to ASIS; + = tenderness)
- rovings sign (palpate LLQ deeply; + = RLQ pain)
- psoas sign (have pt lift right thigh against resistance while supine then extend right hip while lateral recumbent; + = abdominal pain during either)
- obturator sign (flex pt right hip with knee bent then internally rotate the hip; + = right hypogastric pain
special test for biliary colic (pain in gall bladder)
murphys sign - palpate deeply under pt right costal margin and ask pt to breath deeply; + = sharp increases tenderness with sudden stop in inspiration
what are sign of peritoneal inflammation (acute abdomen)
- gaurding (voluntary contraction during palpation)
- rigidity (involuntary contraction of abdominal wall, can see it, can palpate it, and won’t see ab move while breathing)
- rebound tenderness (push down deep and then let go quickly, if more tender when letting go than pushing it is a positive sign)
retrosternal sensation of burning or discomfort usually occurring after eating when lying supine or bending over
heartburn symtpms typical of GERD
what are the typical symptoms of GERD
heartburn
regurgitation
dysphagia (sensation that food is stuck in retrosternal area occurs in 30% of GERD pts)
are coughing, wheezing, hoarseness, sore throat, otitis media, non cardiac chest pain, and enamel erosion typical or atypical signs of GERD
atypical
most common digestive complaint in US
constipation
what are the tools that can be used to categorize constipation
- Rome III criteria (for constipation)
* experienced 2 of the following in past 3 months: < 3 poops/week ; straining ; lumpy/hard stool ; sensation of incomplete defecation ; manual maneuvering required to defecate - Bristol Stool scale
- way for pt and dr. to agree on feces. 3-4 are normal (formed and easy to pass) 1-2 are likely in constipation (separate hard lumps like nuts, sausage shaped but lumpy, hard to pass)
what is rome criteria
-it is a questionnaire to help dx and tx of functional GI problems
made by the Rome foundation to help classify and categorize the GI symptoms associated with illness that are GI in nature with no evidence of organic disease to explain symptom
PE exams for constipation? findings?
- abdomen exam
- constipation: distention, masses, large abdominal hernias may interfere with generation of internal pressure needed to start defecation - pelvic exam for females
- palpate posterior vaginal wall at rest and while straining to check for internal rectal prolapse or rectocele - anorectal exam
- blood? hemorrhoids? pain? mass? sphincter tone? fecal impaction?
a nonspecific term, first seen with diarrhea but also nausea vomiting and abdominal pain , “stomach flu”. usually caused by infectious agent such as virus, bacteria, parasite, food toxin, or drug linked
gastroenteritis
**associated with diarrhea
two viral causes of gastroenteritis
norovirus
-sudden onset of uncontrolled vommiting 12-48 hrs after exposure, vommitting > diarrhea, resolves 36 hrs after start, usually the causes of outbreaks
rotavirus
- will have by age 5 if not vaccinated, can lead to severe dehydration
3 causes of bacterial gastroenteritis
salmonella
-eating something contaminated, onset 12-36 hr after
difficile
-from antibiotic exposure; most common hospital acquired GI illness
coli
- food, water, or person -person transmission. onset within 5 days and lasts 2 weeks,
- most common cause of travelers diarrhea
common cause of parasitic gastroenteritis
giardiasis
- causes diarrhea, FATTY STOOL THAT FLOATS, bloating, ab cramping, N/V
- trasmits by person-person, animals-humans through fecal oral route, most commonly from infected water
drugs associated with diarrhea
- quinidine
- colchicin
- PPI
- antibiotics
- laxatives
- sorbitol
postprandial urgency, alteration between diarrhea and constipation , stubbornness to laxatives, defaction improves ab pressure but does not relieve it are all common signs of
IBS (irritable bowel syndrome )
*abdominal pain/bloating and altered bowel habits
___ volume of stool associated with enteric infection and ____ volume of stool associated with colonic infection
large - enteric (SI)
small-colonic (LI)
copious rice water diarrhea is a hallmark of
cholera
would you do a murphys sign test if you have LLQ?
no
what must happen for vitamin D to increase absorption of calcium from diet
-1 alpha hydroxylase in the kidneys converts calcium into active 1,25 hydroxy state via the stimulation by PTH from the parathyroid gland
what is the most common cause of hypocalcemia
hypoparathyroidism
what is Chvostek sign? and what is it used for?
- for hypoparathyroidism, hypocalcemia
- tap facial nerve and look for a spasm of facial muscles
what is trousseaus sign? and what is it used for ?
- for hypoparathyroidism, hypocalcemia
- characteristic flick of wrist when used a blood pressure cuff on that arm
when doing a workup for hypo/hypercalcemia, you check for calcium, albumin, magnesium, and PTH levels [CAMP levels]. if albumin comes back low you must?
calcium will need to be adjusted bc albumin binds to both H+ and Ca2+
primary vs secondary hyperparathyroidism
**BOTH ARE INCREASED PTH LEVELS
primary: adenoma or hyperplasia of parathyroid gland causes increased PTH secretion and high calcium levels
secondary : low calcium levels cause increased PTH ; possible causes are V-D def, calcium def, malabsorption, renal failure
