not to insert an indwelling urinary catheter

31
Q

Types of bowel function alterations

A
  • diarrhea
  • constipation
  • impaction
  • bowel incontinence
32
Q

diarrhea

A
  • passage of liquid stool
  • increase fluid intake
  • administer antidiarrheal medications
  • assess for cause
33
Q

constipation

A
  • infrequent passage of hard stool
  • increase fluid and fiber intake
  • increase activity level
  • administer enema
  • medications
  • evaluatie medication profile for GI side effects
34
Q

bowel incontinence

A
  • inability to control release of feces
  • administer bowel training
  • treat with surgery
  • remove fecal impaction
  • diet adjustment
  • administer medications
35
Q

impaction

A
  • mass or collection of hardened feces in the folds of the rectum
  • manual removal may be necessary
  • administer enema as necessary
  • evaluate medication profile for GI side effects
  • improve defecation habits and reduce constipation
36
Q

straining a BM

A
  • increases BP
  • inceases ICP
  • tachycardia
  • especially restricted from cardiac patients
37
Q

hemorrhoids

A

dilated, engorged veins in the lining of the rectum

38
Q

urostomy

A
  • surgical procedure that creates a stoma for the urinary system
  • made to avail for urinary diversion in cases where drainage of urine through the bladder and urethra is not possible (after extensive surgery or obstruction)
39
Q

urinary catherization

A
  1. intermittent (I&O)
  2. indwelling (foley)
40
Q

When is it appropriate to catheterize a patient

A
  • urinary retention
  • surgery
  • prolonged surgery
  • epidural prolonged immobilization
41
Q

When is it inappropriate to catheterize a patient?

A

incontinent

42
Q

Safety alert for catheters

A

Vasovagal response

43
Q

vasovagal response

A
  • when the bladder is extremely full and urine rapidly releases into the foley.
  • BP drops and the patient can pass out
  • Clamp and raise legs
44
Q

National Patient Safety Goal

A

use best practices to prevent UTIs

  • strict asepsis
  • closed system
  • lower than bladder
  • never on the floor
45
Q

Interventions after foley removal

A
  • education post removal
  • schedule toileting
  • manual compression of bladder (Rede’s Method, relaxes the bladder)
46
Q

colostomy

A

surgical procedure in which a stoma is formed by drawing the healthy end of the large intestine or colon through an incision in the anterior abdominal wall and suturing it into place

47
Q

Modifiable risk factors for bowel function

49
Q

Urinary Diagnostic Tests

A
  1. 24 hr urine
  2. bladder scan
  3. IVP
  4. Retrograde pyelography
  5. renal arteriograph
  6. Cytoscopy
  7. Kidney biopsy
50
Q

IVP

A

x-ray exam that uses an injection of contrast material to evaluate your kidneys, ureters and bladder and help diagnose blood in the urine or pain in your side or lower back

51
Q

Retrograde Pyelography

A

urologic procedure where the physician injects contrast into the ureter in order to visualize the ureter and kidney. The flow of contrast (up from the bladder to the kidney) is opposite the usual flow of urine.

52
Q

Cytoscopy

A

endoscopy of the urinary bladder via the urethra. It is carried out with a cystoscope. The cystoscope has lenses like a telescope or microscope

53
Q

Bowel Diagnostic Tests

A
  • blood and fecal tests
  • digital rectal exam
  • colonoscopy
  • enema x-ray
  • defecography
  • anorectal manometry
54
Q

Urinary Function: Children

A
  • Potty trained at 2-4 yrs old
  • day time control before night time control
55
Q

Urinary Function: Elderly

A
  • decreased kidney size
  • decreased tone and elasticity of bladder, ureters, and urethra
  • decreased bladder capacity
56
Q

Urinary Function: Pregnancy

A
  • increased pressure on bladder
  • increased frequency of urination
57
Q

Collaborative Urinary Management

A
  1. pharmacologic therapy
  2. dialysis
58
Q

dialysis

A
  1. peritoneal dialysis
  2. hemodialysis
59
Q

hemodialysis

A

Blood flows through catheters —> passes by dialysis solution in an external machine —> returns to patient

60
Q

peritoneal dialysis

A

dialysis solution is instilled into abdominal cavity through a catheter —> allowed to rest there while fluid and molecules exchange —> removed through the catheter

61
Q

Collaborative Bowel Management

A
  1. Meds (laxatives, antidiarrheal, stool softeners)
  2. Surgical resection with or without an ostomy
62
Q

EBP constipation management

A
  1. increased fluid and fiber
  2. dietary education
  3. bowel training (digital stimulation)
  4. Kegel exercises and biofeedback used to strengthen rectal muscles
  5. “no strain” education
