Week 6 Urinary and Bowel Flashcards
1
Q
What are the functions of the kidneys
A

3
Q
What is the process of urinary elimination
A

What are the normal stool characteristics and variations that occur with frequency, color, shape, consistency, and odor
1. frequency: Normal = 2-3 BMs/week
Variations:
- hypermotility = >6 stools/day
- hypomotility <1 stool/week
2. color: normal = brown
Variations:
- white or clay colored = absence of bile or use of antacids
- light brown = diet high in milk or low in meat

Variations:
- narrow, pencil shaped
- intestinal obstruction or constipation
- small marble shaped
- slow peristalsis
```
4. consistency: Normal = formed, soft, moist
Variations:
- hard stool = constipation, dehydration
- liquid stool = diarrhea, rapid peristalsis
5. odor: normal: pungent, affected by foods
Variations:
- strong foul odor
- blood in stool or infection

29
What are the risk factors, assessments, and complications for constipation
Risk factors;
- short term = lifestyle factors
- long term = physiological factors
Assessment:
- subjective = abdominal pain, tenderness, loss of appetite, rectal pressure, fatigue, indigestion
- objective = abdominal distention, blood with stool, decreased stool frequency and volume, hard stools, hypo or hyperactive bowel sounds
Complication:

- antidiarrheal medications: not recommended for acute diarrhea, Lomotil, Imodium, teach clients about over the counter aids, not used very often (never used for kids)
32
What are the managements for constipation
- increase intake of high fiber foods
- increase fluid intake
- increase activity/exercise
- provide privacy
- help client to a position that facilitates defecation (ideally seated position)
- allow uninterrupted time
- offer laxatives when lifestyle changes are ineffective to avoid body becoming accustomed to drugs
33
What are the managements for bowel incontinence
1. monitor bowel pattern and skin breakdown, redness or irritation
2. toileting (uninterrupted time, or attempt at regular intervals and time most likely to occur)
3. skin care: change ASAP, prompt hygiene care, keep skin scrupulously clean, use skin protection products
4. absorbent products: pads and shield; never refer to incontinence pads as diapers
5. fecal drainage device
6. bowel training
34
What are the advantages and limitations of external collection devices used for bowel incontinence
Advantages: prevent skin breakdown, minimize odor, track output accurately, and enhance patient comfort
Limitations: not for ambulatory, agitated, or active clients - dislodged, causing skin breakdown
35
What are the advantages and disadvantages/precautions of internal drainage devices used for bowel incontinence
Advantages: protect perianal skin, protect caregivers from potentially infectious stool, decrease urinary tract infections
Disadvantages and precautions: FDA approved, only 29 consecutive days, and not for pediatric patients. Other contraindications include severe hemorrhoids, recent bowel, rectal, or anal surgery or injury, rectal or anal tumors, stricture or stenosis; pressure directly on colon wall
36
What are the points to remember when establishing a bowel training program
- plan program with the client
- increase fiber in diet gradually
- increase fluid intake to eight glasses of water per day
- establish a designated time for defecation
- privacy should be provided for the client
- the treatment plan should be staged
- the treatment may include a stool softener
- the plan should be modified based on client results
37
What are the managements for a bowel diversion
1. stoma assessment and care
- pay strict attention to skin care/periostomal skin assessment
- monitor the amount and type of effluent (contents of what is coming out; dependent on what part of the bowel the stoma is placed in)
2. be attentive to client's psychosocial needs
- be professional; show acceptance
- attend to odor control
- address client participation in ostomy care
3. client teaching for home care
- dietary changes associated with an ostomy
- changed when 1/3 full to prevent leaking
- be aware of when the patient has gas because it can fill with warm air and cap can pop off and cause a mess
38
What are the general dietary guideline for ostomies
- may begin with bland, low residue or soft diet for 1-2 months (to allow body to adapt)
- eat three or more meals at regular times
- drink additional fluids
- avoid chewing gum
- avoid foods that cause gas, odor, blockage or loose stool
- chew food well
