Abdomen (Exam 3) Flashcards
Linea alba
midline, tendinous seam joining the 4 layers of abdominal muscles
Muscles serve as protection of _______ and they flex the __________
internal organs; vertebral column
Peritoneum
envelope of serous membrane; parietal and visceral
Parietal peritoneum
lines the abdominal wall
Visceral peritoneum
covers the surface of most abdominal organs
Mesenteries
supporting networks to suspend and stabilize the abdominal organs (viscera); pathways for blood vessels, nerves and lymphatics
Greater omentum
specialized fatty mesentery overlies the ventral abdomen
Solid viscera
maintains characteristic shape; LIVER, PANCREAS, SPLEEN, ADRENAL GLANDS, KIDNEYS, OVARIES, UTERUS
Hollow viscera
shape depends on contents; STOMACH, GALLBLADDER, SMALL INTESTINE, COLON, BLADDER
USUALLY NOT PALPABLE
Spleen
mass of lymphatic tissue
ONLY PALPABLE IF ENLARGED
Aorta
able to palpate pulsations in the upper anterior abdominal wall
Costovertebral angle (kidneys)
angle formed with the 12th rib and the vertebral column, where the left kidney lies
Right Upper Quadrant (RUQ) organs
liver
gallbladder
duodenum
head of pancreas
right kidney and adrenal
part of ascending and transverse colon
Left Upper Quadrant (LUQ) organs
stomach
spleen
left lobe of liver
body of pancreas
left kidney and adrenal
splenic fixture of colon
part of transverse and descending colon
Right Lower Quadrant (RLQ) organs
cecum
appendix
right ovary and tube
right ureter
right spermatic cord
Left Lower Quadrant (LLQ) organs
part of descending colon
sigmoid colon
left ovary and tube
left ureter
left spermatic cord
Midline organs
aorta
uterus (if enlarged)
bladder (if enlarged)
What are the 9 regions of the abdomen?
- Epigastric
- Umbilical
- Hypogastric/Suprapubic
- Right epigastric (hypochondriac)
- Left epigastric (hypochondriac)
- Right umbilical/lumbar
- Left umbilical/lumbar
- Right hypogastric (inguinal)
- Left hypogastric (inguinal)
Developmental Considerations: Infants and Children
umbilical cord shows prominently on abdomen in newborns (contains 2 arteries and 1 vein)
abdominal wall less muscular, organs may be easier to palpate
urinary bladder is higher up in abdomen
Developmental Considerations: Pregnancy
morning sickness (nausea/vomiting, related to hormonal changes)
GI motility decreases (constipation which could lead to hemorrhoids)
heartburn, esophageal reflux
intestines are displaced upwards
bowel sounds diminished
Developmental Considerations: Aging Adult
motility and peristalsis slows (constipation increases)
fat becomes more pronounced in abdomen (weakening muscles makes a potbelly)
symptoms of acute disease may be diminished (less pain, fever less pronounced)
salivation decreases (dry mouth, decreased taste)
esophageal emptying slowed (feed in upright position)
liver size decreases with age (blood flow to liver decreased by 55%, metabolism of drugs is decreased with age)
Is constipation a physiological cause of aging?
NO!
What are 8 common causes of constipation?
- Decreased physical activity
- Inadequate intake of water
- Low-fiber diet
- Side effects of medications
- IBS
- Bowel obstruction
- Hypothyroidism
- Inadequate toilet facilities (difficulty ambulating to toilet can cause someone to hold it in until it becomes hard and difficult to pass)
Pica
eating non-nutritious food substances like grass, clay, stones, etc.
common in early childhood, pregnancy and psychologically impaired
DUE TO IRON DEFICIENCY? CAN RESULT IN EMERGENT SITUATIONS LIKE INTOXICATION AND INTESTINAL OBSTRUCTION
Diarrhea
ask about bowel routine (ask what is normal and how has it changed?)
use of OTC meds to promote or control bowels? regular or occasional usage?
Melena
blood in the stool; may appear bright red, maroon or black and tarry
Constipation
fecal impaction; less than 2 times a week
Dysphagia occurs with disorders of the throat or esophagus, such as…
thrush (candida infection)
neurologic changes (stroke)
obstruction (solid mass or tumor)
Dysphasia
partial or complete impairment in the ability to speak
Pyrosis
burning as in heartburn
Hematemesis
vomiting of blood
Hemorrhoids
varicose veins in the rectal area due to straining, pregnancy, or obesity
