Week 9 - Chapter 22 Flashcards
(54 cards)
What are the Surface landmarks of the abdomen ?
The abdomen is a large oval cavity extending from the diagphragm down to the top of the pelvis
It is bordered in the back by a vertebrael column and paravertebrael muscle
Bordered at the sides and front by the lower rib cage and abdominal muscles
There are four layers of large, flat muscles from the ventral abdominal wall that are joined at the midline by a tendinous seam called the Linea Alba
The Rectus Abdominis forms a strip extending the length of the midline and its edge is often palpable
The muscles protect and hold the organs in place and flex the vertebrael column

What is the Viscera ?
All the internal organs are called the Viscera

What is the Solid Viscera ? What does it contain ?
Solid Viscera are those that maintain a characteristic shape (liver, pancrease, spleen adrenal glands, kidneys, ovaries, uterus)
Liver fills most of the Right Upper Quadrant (RUQ) and extends over the midclavicular line - the lower edge of the liver and the right kidney may normally be palpable
Ovaries are normally palpable only on bimanul assesment during pelvic examination
What is the hollow viscera ? What does it contain ?
The Hollow Viscera shape is dependent on its contents (stomach, gallbladder, small intestine, colon, bladder)
They are not usually palpable - stomach is just below the diagohragm between the liver and spleen
Gallbladder rests under the posterior surface of the liver just lateral to the right midclavicular line
The small intestine is located in all four quadrants extending from the right stomachs pyloric valve to the ileocecal valve in the Right Left Quadrant (RLQ) where it joins the colon
What is the spleen ?
The spleen is a soft mass of lymphatic tissue on the posterolateral wall of the abdominal cavity, immediately under the diaphragm
It lies obliquely with its long axis behind and parallel to the tenth rib, lateral to the midaxilaary line
Width extends approximately 7cm from the 9th to the 11th rib - normally not palpable
** if it becomes enlarged, its lower edge moves downward and toward the midline**
What is the Aorta ?
The aorta is just left of midline in the upper part of the abdomen
It descends behind the peritoneum and bifurcates 2 cm below the umbilicus into the right and left common iliac arteries opposite the fourth lumbar vertebra
Aortic pulsations can be palpated easily in the upper anteriorabdominal wall
The right and left iliac arteries become the femoral arteries in the groin area.
Their pulsations are also easily palpated, at a point halfway between the anterior
superior iliac spine and the symphysis pubis
What is the Pancreas ?
The pancreas is a soft, lobulated gland located behind the stomach
It stretches obliquely across the posterior abdominal wall to the left upper quadrant (LUQ)
What are the Kidneys ?
The bean-shaped kidneys are retroperitoneal, or posterior to the abdominal contents
They are well protected by the posterior ribs and musculature
The twelfth rib forms an angle, the costovertebral angle, with the vertebral column
The left kidney lies at that point, at the eleventh and twelfth ribs
Because of the placement of the liver, the right kidney rests 1 to 2 cm lower than the left kidney and is sometimes palpable
How many Quadrants in teh abdomin divided into ?
Four Quadrants - by a horizontal and vertical line bisecting the umbilicus
Epigastric is the area between the costal margins
Umbilical is for the area around the umbilicus
Hypogastric or Suprapubic for the area above the pubic bone
What does each of the four quadrants posses ?
Right Upper Quadrant (RUQ): Liver, Gallbladder , Duodenum, Head of pancreas , Right kidney and adrenal gland, Hepatic flexure of colon, Parts of ascending and
transverse colon
Left Upper Quadrant (LUQ): Stomach, Spleen, Left lobe of liver, Body of pancreas , Left kidney and adrenal gland, Splenic flexure of colon, Parts of transverse and descending colon
Right Lower Quadrant (RLQ): Cecum, Appendix, Right ovary and fallopian tuve, right ureter, right spermatic cord
Left Lower Quadrant (LLQ): Part of descending colon, Sigmoid colon, Left ovary and fallopian tube, Left ureter, Left spermatic cord
Midline: Aorta, Uterus (If enlarged), Bladder (If enlarged)
What are some developemental considerations for infants and children ?
In newborns, the umbilical cord shows prominently on the abdomen - It contains two arteries and one vein
The liver takes up proportionately more space in the abdomen at birth than in later life - In healthy full-term newborns, the lower edge may be palpated 0.5 to 2.5 cm below the right costal margin
The urinary bladder is located higher in the abdomen in newborns than in adults - It
lies between the symphysis and the umbilicus
During early childhood, the abdominal wall is less muscular, which may
make the organs easier to palpate
Children with gastroenteritis, particularly those younger than 1 year of age, are at increased risk for dehydration because of their relatively small body weights and high turnover of water and electrolytes
Signs of clinical dehydration that indicate increased risk for progression to shock include altered responsiveness (irritability, lethargy), sunken eyes, tachycardia, tachypnea, and reduced skin turgor
What are developemental considerations for pregnant women ?
Nausea and vomiting, or “morning sickness,” is an early sign of pregnancy in many pregnant women, starting between the first and second missed periods
Another symptom is “acid indigestion,” or heartburn, caused by esophageal reflux
Elevated levels of progesterone relax all smooth muscle, which leads to a decrease in gastro-intestinal motility and prolongation of gastric emptying time
As a result of decreased motility, more water is reabsorbed from the colon, which leads to constipation
Constipation as well as increased venous pressure in the lower pelvis, may lead to formation of hemorrhoids.
The enlarging uterus displaces the intestines upward and posteriorly - Bowel sounds are diminished
Although the appendix may move during pregnancy, causing appendicitis-related pain in an atypical location - most pregnant women with appendicitis experience RLQ pain
Skin changes on the abdomen, such as striae and linea nigra
What are some developemental changes for older adults ?
Aging alters the appearance of the abdominal wall
During and after middle age, some fat accumulates in the suprapubic area in women as a result of decreased estrogen levels
Men also show some fat deposits in the abdominal area, resulting in the “big belly.”
This development is accentuated in adults with a sedentary lifestyle -With further aging, adipose tissue is redistributed away from the face and extremities to the abdomen and hips, and the abdominal musculature relaxes
Changes of aging occur in the gastro-intestinal system but do not significantly affect function as long as no disease is present
• Salivation decreases, causing dryness of the mouth and a decrease in the sense of taste
• Esophageal emptying is delayed. Feeding an older adult in the supine position increases the risk for aspiration
• Gastric acid secretion decreases with aging. As a result, the absorption of orally administered medications may be impaired or delayed. This may cause pernicious
anemia (as a result of impaired vitamin B12 absorption), iron deficiency anemia, and malabsorption of calcium.
- Older adults are more susceptible to dehydration because the ability to conserve water is reduced, as are the ability to respond to changes in temperature and the acuteness of thirst
- Liver size decreases with age, particularly after 80 years, although most liver function remains normal - Age-related reductions in liver blood flow and medication-metabolizing enzyme content influences medication metabolism and the variability in response to beneficial and adverse medication effects seen in older adults
- Renal function decreases with age, contributing to the increased risk for adverse or toxic medication effects, as most medications are eventually cleared through the kidneys after metabolism in the liver. Older adults who drink alcohol and take medications are at even greater risk, including exacerbation of therapeutic and adverse effects and interference with medication effectiveness
- The incidence of gallstones increases with age, occurring in up to 20% of Canadian women and 10% of Canadian men by age 60.5
- Age-related changes alone do not account for the frequent reports of constipation by older adults. Common risk factors in older adults include functional impairments such as decreased mobility, pathological conditions such as hypothyroidism, adverse medication effects, and poor dietary habits, including inadequate intake of fluids and fibre
- Additional lifestyle factors that contribute to constipation include prolonged use and overuse of laxatives; ignoring the defecation urge; sedentary lifestyle; and polypharmacy
- Medications associated with constipation include opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), antacids containing aluminum or calcium,anticholinergics (e.g., anticonvulsants, antidepressants,antiparkinson agents) diuretics, calcium channel blockers, and calcium or iron supplements
- The risk for colorectal cancer increases with age
Who is affected by obesity the most ? what is GERD ?
Prevalence of obesity in women in low income households is higher compatred to women in higher income households
Obesity increases the risk of diabetes, cncer (esophageal cancer), digestive problems such as gallstones, fatty liver, cirrhosis, and Gastroesophageal reflux disease (GERD)
Risk factors for GERD incluce age, obesity, hiatus herbia, smoking, pregnancy, food choices, and family history with GERD
What is Lactose Intolerance ?
Lactose Intolerance - these individuals have lower levels of lactase that is the intestinal enzyme that digests lactose - avoidance of milk products can compromise calcium and vitamin D intakes - research has found that lactose-intolerant individuals can consume moderate amounts of lactose without perceptible symptoms
What is Celiac Disease ?
Celiac disease is an inherited autoimmune condition in which intestinal tissue is damaged in response to eating gluten, which prevents nutrients from being properly absorbed
Untreated celiac disease can lead to medical problems such as lactose intolerance, malnutrition, osteoporosis, colon cancer, and lymphoma
What are gastro-intestinal Ulcers ?
Canada has the highest incidence of gastro-intestinal ulcers in the world
Peptic ulcer disease increases with age and occurs with frequent use of NSAIDS, alcohol, smoking, and infection with Helicobacter pylori
Eight to 10 million Canadians have H. pylori infection, which is also associated
with development of stomach cancer; approximately 75% of First Nations people are infected with H. pylori
What is Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)?
Canada also has among the highest prevalence and incidence rates of inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) in the world
IBD can be diagnosed at any age, but usual onset is in the 20s for Crohn’s disease and throughout adulthood for ulcerative colitis; incidence for both diseases peaks by age 30 and does not decline until age 80
A diagnosis of IBD is associate with a higher risk for colorectal cancer
Infectious diseases such as hepatitis A and gastro-intestinal illnesses are often related to socioeconomic factors such as inadequate housing, sewage, and water-treatment facilities
These conditions are often present in Indigenous communities
The most common gastro-intestinal and parasitic infections in refugee populations are Giardia, worm infections (e.g., roundworm [Ascaris], whipworm [Trichuris], and hookworm), and parasites of the Strongyloides and Schistosoma species
What are self-management measures to maintain the liver ?

How does one inspect the abdomen ?
Inspect Contour: Stand on the patient’s right side and look down on the abdomen. Then stoop or sit to gaze across the abdomen - Your head should be slightly higher than the abdomen - Determine the profile from the rib margin to the pubic bone -
The contour describes the nutritional state and normally ranges from flat to rounded
Inspect Symmetry: Shine a light across the abdomen toward you or lengthwise across the patient - The abdomen should be symmetrical bilaterally -Note any localized bulging,visible mass, or asymmetrical shape - Even small bulges are highlighted by shadow - Step to the foot of the examination table to recheck symmetry - Ask the patient to take a deep breath to further highlight any change - The abdomen should stay smooth and symmetrical - You can also ask the patient to perform a sit-up without the hands to push up
