Q

Types of hernias?

A

Umbilical:
-located by the umbilicus

Inguinal:

  • direct: defects and weakness of the posterior inguinal wall, usually affect older adults
  • indirect: congenital

Femoral

17
Q

Bowel assessment shape and consistency

A

Shape:
Normal- approx. 1” in diameter about size of rectum
Narrow/pencil like- constriction, obstruction, rapid peristalsis
Small marble- slow peristalsis longer time in intestine
Consistency:
Normal- formed moist and soft
Hard- constipation, dehydration
Liquid- diarrhea, rapid peristalsis, infection

18
Q

Patient teaching for constipation

A

Increase fluid intake at least 2500 mL/day
Drink glass of warm water before breakfast
High natural fiber diet unless contraindicated
Encourage ambulation or chair exercises
Doctor may prescribe bulk laxatives long term
Laxatives for occasional use not long term
Provide privacy
Keep patient routines

19
Q

Hemorrhoid what are they and causes

A

Rectal lesion common in adults classified as internal or external

Straining to defecate
Pregnancy
Prolonged sitting
Obesity

20
Q

Hemorrhoid assessment, internal

A
Internal:
Rarely cause pain
Usually have bleeding that is bright red
Recurrent bleeding may cause anemia
Mucous discharge and feeling of incomplete emptying of stool
21
Q

Hemorrhoid assessment, external

A

External:
Bleeding is rare
Anal irritation
Feeling of pressure
Difficulty cleaning anal region
Enlargement may cause protrusion through anus
Prolapsed hemorrhoids can be extremely painful

22
Q

Hemorrhoidectomy nursing care

A

Pain: meds, ice, sitz bath, side laying
Stool softeners as prescribed, constipation common post op
Encourage fluid intake
Report bleeding, fever >100, purulent drainage

23
Q

Bowel obstruction, what is it?

A

Failure of intestinal contents to move through the bowel lumen. More commonly involving the small intestine

24
Q

Bowel obstruction risk factors

A

Previous abdominal surgery
Complains of abdominal pain, bloating, constipation
Previous history of bowel obstruction
Inflammatory bowel disease history

25
Q

Bowel obstruction, mechanical

A
Mechanical:
Scar tissue (adhesions)
Hernias (strangulated)
Inflammatory bowel disease
Tumors
26
Q

Bowel obstruction, funtional

A

Functional:
Peristalsis fails to propel intestinal contents
No mechanical causes
Paralytic ileus most common following abdominal surgery

27
Q

Assessment of small bowel obstruction, high obstructions

A

Vomiting (bile and mucus)
Abdominal distention minimal
Cramping

Bowel sounds high pitched and tinkling present in attempt to propel past obstruction
Paralytic ileus: bowel sounds diminished or absent
Fluid and electrolyte imbalances occur r/t vomiting
H2O and sodium drawn into bowel causing vascular fluid losses causing hypovolemia

28
Q

Assessment of small bowel obstruction, low obstruction

A

Vomiting (fecal matter)
Flatus and feces present are expelled then cease
Abdominal distention pronounced
Cramping

Bowel sounds high pitched and tinkling present in attempt to propel past obstruction
Paralytic ileus: bowel sounds diminished or absent
Fluid and electrolyte imbalances occur r/t vomiting
H2O and sodium drawn into bowel causing vascular fluid losses causing hypovolemia

29
Q

Medical treatment for obstructions

A

Most partial small bowel obstruction treated with NG tube

  • low suction to decompress abdomen
  • collects fluids and gas
  • Allows bowel to rest until peristalsis resumes or obstruction is relieved
30
Q

Surgical treatment for obstructions

A

Required for complete mechanical obstruction and strangulated obstruction

  • lysis of adhesions
  • resection of tumor
  • foreign body removal
  • colostomy may be performed to relieve obstruction

NG tube inserted prior and IV fluids to repair electrolyte imbalances particularly potassium prior to surgery

31
Q

Why an ostomy?

A
Traumas (gun shot wounds)
Inflammatory bowel disorders (colitis, Crohns)
Tumors/cancer resections
Bowel perforation
Necrotic bowel
32
Q

Types of ostomy

A

Precise name of the ostomy depends upon its location of the stoma

  • ileostomy
  • cecostomy
  • ascending colostomy
  • transverse colostomy
  • descending colostomy
  • sigmoid colostomy
33
Q

Permanence ostomy, temporary and permanent

A

Temporary:
Traumatic injury or inflammatory condition
Allow the distal portion of the bowel to rest and heal

Permanent:
Done when anus or rectum is nonfunctional (birth defect, cancer of bowel)

34
Q

Ileostomy information

A

Opening made in ileum of small intestine
Generally colon and rectum removed, anus closed
Stool is liquid in nature
Loop ileostomy is temporary

35
Q

Continent ileostomy info

A

Intra-abdominal reservoir constructed and valve formed to prevent leaking
Catheter is inserted into pouch to drain stool
Not frequently seen

36
Q

Ileostomy nursing care post-op assess

A

Bleeding- small amounts
Stoma viability- healthy is pink, red, moist
Function- initial drainage dark green odorless. Later it thickens and is yellow brown
Empty- when nor more 1/3 full
Include contents as output

37
Q

Ileostomy teaching

A

Self care
Meticulous skin care around peri-stomal area
Adequate fluid intake, high risk for dehydration
Report increase in stool frequency and amount
Low residual diet, no whole grains, seeds, spicy
Teach s/s food blockage- cramping, swelling of stoma, no output from stoma 4-6 hours

38
Q

Colostomy stool characteristics

A

Ascending colostomy: fluid to semi fluid stool
Transverse colostomy- mushy stool
Descending colostomy- semi solid stool
Sigmoid colostomy- more solid stool/common permanent

39
Q

Colostomy nursing care

A

Assess location of stoma and type of colostomy
Stoma appearance and surrounding skin
Cleanse around stoma with water, soap if sticky or stool present
Skin barriers
