Q

Auscultation Bowel sounds

A
  • note character and frequency
  • bowel sounds: movement of air and fluid through the small intestine
  • depending on the time elapsed since eating, a wide range of normal sounds can occur
  • bowel sounds are high pitched, gurgling, cascading sounds, occurring irregularly anywhere from 5 to 30 times per minute
  • do not bother to count them. Judge if they are normal, hypoactive or hyperactive

Auscultation bowel sounds

what is hyperactive sounds?

A
  • loud, high-pitched, rushing, tinkling sounds signal increased motility
  • one type is fairly common; the hyperperistalsis (increased motility) when you feel your “stomach growling,” termed borborygmus (BOR-boh-RIG-mus); loud, easily audible.

Q

Palpation

A
  • identifies areas of tenderness, distension and masses
  • empty bladder
  • light palpation gives a generalized idea before going deeper
  • only proceed deeper when warranted and never do deep/firm palpation on a mass
  • use a systemactic approach for each quadrant
  • observe for guarding, grimacing, or other signs of discomfort.
  • rebound tenderness, press onto the involved area and let go. Pain upon rebound indicates peritoneal tenderness common with appendicitis or peritoneal injury.
  • do not palpate a pulsating abdominal mass. This might indicate an abdominal aortic aneurysm. this is why we observe/inspect FIRST

Q

referred pain

A
  • referred pain happens when nerve fibers from regions of high sensory input (such as the skin) and nerve fibers from regions of normally low sensory input (such has the internal organs) happen to converge on the same levels of the spinal cord.
  • the best known ex. is pain experienced during a heart attack. Nerves from damaged heart tissue convery pain signals to signals to spinal cord levels T1-T4 on the left side, which happen to be the same levels that receive sensation from the left side of the chest and part of the left arm.

A
39
Q

Altered elimination

Diarrhea

A
  • diarrhea reflects increased water content of the stool, whether due to impaired water absorption and or active water secretion by the bowel
  • severe infectious diarrhea: number of stools may reach 20 or more per day with defecation occurring every 20 to 30 mintues , the total daily volume of stool may exceed two liters with resultant electrolyte imbalances especially volume depletion and hypokalemia.
40

42
Q

types of laxatives

Bulk forming

A

action: increased the fluid, gaseous or solid bulk in the intestines

teaching info: may take 12 or more hours to act, sufficient fluid must be taken. Safe for long-term use, slow -acting may take several days

43
Q

Types of Laxatives

Emollient/ stool softener

A

actions: softens and delays the drying of the feces; permits fat and water to penetrate feces

44
Q

Types of laxatives

Stimulant/irritant (Dulcolax, senna)

A

actions: irritates the intestinal mucosa or stimulates nerve endings in the wall of the intestine, causing rapid propulsion of the contents

patient teaching: acts more quicly than bulk, forming agents

45
Q

Types of laxatives

Stimulant/irritant (Dulcolax, senna)

A

actions: irritates the intestinal mucosa or stimulates nerve endings in the wall of the intestine, causing rapid propulsion of the contents

patient teaching: acts more quicly than bulk, forming agents

46
Q

Types of laxatives

Lubricant (mineral oil

A

Lubricates the feces in the colon

Patient teaching: prolonged use inhibits the absorption of some fat-soluble vitamins.

47
Q

Types of laxatives

Saline/ Osmotic

(epsom salts, magnesium citrate)

A

action: draws water into the intestine by osmosis, distends bowl and stimulates peristalsis

teaching : can cause fluid and electrolyte imbalance, particularly in older people and children with cardiac and renal disease. should not be used by older clients
prolonged use inhibits the absorption of some fat-soulble vitamins.

48
Q

Types of Laxatives

New eletrolyte- free (miralax)

A

patient teaching: a new laxative that is helpful in the treatment of constipation in children. it is a powder that is tasteless when mixed in a flavored liquid such as juice. It is a prescription drug and cost more than OTC laxatives.

49
Q

Valsalva Maneuver

A

-straining to have a bowel movement can be dangerous for patients with coronary artery disease, HTN, cerebral edema, heart failure

patient inspires deeply and holds breathe while contracting abdominal muscles and bearing down, intra-abdominal and intra thoracic pressure, venous return to heart, transient bradycardia, BP, CO

paitent relaces, intra abdominal and intra thoracic pressure sudden flow of blood to heart tachycardia, BP

can be fatal for patient unable to compensate for sudden hemodynamic changes

may also cause dysrhythmias

50
Q

Flatulence

A
  • gas (flatus) in lumen intestines
  • product of bacterial activity (methane, hydrogen sulfide, etc)
  • average: individual produces 1/2 liter of gas/day; more depending on diet bacterial interaction
  • if isnt passed, may cuase distension and severe pain (like shrek says, better out than in)
  • post op patients; passing gas is a goof thing
51
Q

Hemorrhoids

A
  • prolapsed varricose veins of the rectum
  • increased venous pressure r/t constipation; straining, pregnacy weight lifiting
  • result in bleeding (bright red), pain, itching

treatment approaches

  • avoid constipation
  • warm sitz bath
  • cortisone cream/ suppository
  • sclerotherapy
  • Hemorrhoidectomy
52
Q

Ostomies/diversions

A

reasons for ostomies/ bowel diversion

  • cancer
  • tramua
  • bowl disease (crohns)
  • Blockage
  • Diverticulitis

Ostomies
Location determines stool consistency due to the varying time for GI contents to digest and absorb H20

can be permanent or temporary, depending on underlying reason for ostomy

Stoma: intestinal opening

53
Q

Bowel Diversions

A

Location of ostomies

Duodenum: small intestine nearest stomach

Jejunum- middle section of small intestine between duodenum and ileum

lleum- end of the small intestine

colon

54
Q

bowel diversions

A

changes fecal consistency based on processes that normally occur before/after location

large intestine reabsorbs water

the more of large intestine removed the less water reabsorbed the softer the feces.

Loop colostomy: a loop of colon is pulled out through a cut in your tummy. The loop is opened up and stitched to your skin to form an opening called a stoma. The stoma has 2 openings that are close together. One is connected to the functioning part of your bowel, where waste leaves your body after the operation.

55
Q

GUAIAC FECAL OCCULT BLOOD TEST

A

-Detects GI bleeding (most commonly from colorectal
CA); routine screening for age > 50 yrs.

Relatively insensitive (< 30% carcinomas bleed
sufficiently to be detected by this test), but if done in
concert with colonoscopy/sigmoidoscopy  mortality
  • normal= negative
  • Collection: diet free of exogenous peroxidases (fish, horseradish, turnips), no vitamin C, no medicines that irritate GI tract (e.g NSAIDS)
  • patient collects 2-3 consecutive stool specimens; uses a wooden stick to place sample on assay card (rectal exam sample may also be used)
56
Q

GUAIAC FECAL OCCULT BLOOD TEST

A

-Abnormal= positive
-Colon or rectal polyps or cancer, hemorrhoids, anal
fissures, esophageal or gastric cancer, peptic ulcers,
ulcerative colitis, Crohn’s disease, GERD, esophageal
varices

False positive
-Recent dental procedure with bleeding gums, eating
red meat within 3 days of test, fish, turnips,
horseradish, high doses of Vitamin C, NSAIDs

57
Q

Geriatric GI changes

A

decrease in salivary secretion

tooth enamel and dentin erode contributing to tooth loss and gum erosin

greater incidence of hiatal hernia and gastroesophageal reflux

increased gastric emptying time

liver decreases in weight and size and liver blood flow decreases

increased incidence of gallstones

decrease production of intrinsic factor contributing to development of pernicious anmeia

constipation becomes more common but probably more a result of lifestyle factor than physiological change

absorption of proteins, fats, minerals and some vitamins occurs more slowly

some delay in gastric mobility and emptying

weakening of intestinal walls with greater incidence of diverticulitis

decreased acid production contributing to achlorhydria

decreased esophageal mobility

taste buds decrease in number.
