Q

Discuss urinary and bowel elimination changes related to older adults

A
  • Diminished ability of the kidney to concentrate urine (tubular reabsorption and tubular secretion)
  • Decreased bladder muscle muscle tone may reduce bladder capacity
  • Decreased bladder contractility may lead to urine retention and stasis
  • Neuromuscular problems, degenerative joint disease, alteration in thought process and weakness may interfere with voluntary control.
  • Medications prescribed for other health problems (diuretics, sedatives, tranquilizers)
  • Some view themselves as old, powerless and neglected.

Q

Nursing process of assessment for urination

A
  • Conduct a detailed health history & physical assessment
  • Assessment of the bladder for distention = using a bladder scanner to assess the amount of urine in the bladder not excreted completely (urinary retention/ post-void residual)
  • Check for inflammation in the urethral orifice
  • Check for skin integrity from incontinence
  • Assess hydration status
  • Measure urine output
  • Assess the patients urine through urinalysis (at least 10ml)

A

Cystitis

30
Q

TREATMENT AND PATIENT EDUCATION TO PREVENT UTIs

A

-Drink six to eight 8-oz glasses of liquid daily.
- Do not postpone going to the bathroom; urinate when you feel the urge.
- Take enough time to fully empty the bladder when urinating.
- If you have female genitalia, dry the perineal area after urination or defecation from the front to the back (from the urethra toward the rectum.
- Void before and after sexual intercourse
- If you have repeat bladder infections and use a diaphragm, unlubricated condoms, or spermicide, talk with your health care professional about switching birth control methods; these methods can increase the chances of developing a bladder infection.
- Wear underwear with a cotton crotch and avoid clothing that is tight and restrictive on the lower half of the body.

31
Q

When do we use urinary catheterization?

A
  • Relieving acute urinary retention. Retention is often temporary and is common after surgery involving the lower abdomen, pelvis, bladder, or urethra, especially if ambulation is delayed, fluid intake is minimal, or epidural analgesia is used for pain control. Bladder outlet obstruction, including mechanical obstruction such as swelling at the meatus (which can occur after childbirth), or an enlarged prostate in males may cause retention.

-Some patients who are unable to use any other bladder management method, such as those with neurogenic bladder dysfunction related to a disability (e.g., spinal cord injury) or intractable urinary retention, require long-term use of an indwelling catheter.

-Obtaining a sterile urine specimen when the patient is unable to voluntarily void.

-Accurate measurement of urinary output in critically ill patients.

-Assist in healing open sacral or perineal wounds in incontinent patients.

-Emptying the bladder before, during, or after select surgical procedures and before certain diagnostic examinations.

-Provide improved comfort for end-of-life care.

-Prolonged patient immobilization (potentially unstable thoracic or lumbar spine, multiple traumatic injuries).

32
Q

Types of catheters:
Intermittent urethral catheters (straight catheters)

A
  • used to drain the bladder for short periods.
    Intermittent catheterization should be considered as an alternative to short-term or long-term indwelling urethral catheterization to reduce CAUTIs (catheter-associated UTI)

Certain advantages to intermittent catheterization, including the lower risks of CAUTI and complications, may make it a more desirable and safer option than indwelling catheterization

33
Q

What is the preferred catheterization method for patients with urinary retention and bladder-emptying dysfunctions and following surgical interventions ?

A

Intermittent catheterization is the preferred due to a lower risk of CAUTI.

34
Q

When do we use an indwelling catheter (Foley catheter)?

A

If a catheter is to remain in place for continuous drainage; The indwelling urethral catheter is designed so that it does not slip out of the bladder. A balloon is inflated to ensure that the catheter remains in the bladder once it is inserted.

  • Indwelling catheters are used for the gradual decompression of an overdistended bladder, for bladder drainage, and for continuous bladder drainage and irrigation.
35
Q

CARING FOR PATIENTS WITH AN INDWELLING CATHETER

A
  • Wash hands before and after caring for the patient.
  • Use mild soap and water or a perineal cleanser to clean the perineal area thoroughly, especially around the meatus, daily and after each bowel movement. Rinse the area well.
  • Do not use powders and lotions after cleaning.
  • Do not use antibiotic or other antimicrobial cleaners or betadine at the urethral meatus.
  • Cleanse the catheter by cleaning gently from the meatus outward.
  • Make sure that the patient maintains a generous fluid intake, unless contraindicated by other health concerns. This helps prevent infection and irrigates the catheter naturally by increasing urine output.
  • Encourage the patient to be up and about, as ordered.
  • Note the volume and character of urine, and record observations carefully. Observe the urine through the drainage tubing and in the collection container.
  • Note and record the amount of urine on the patient’s intake-and-output record every 8 hours.
  • Empty the urine into a graduated container that is calibrated accurately for correct determination of output.
  • When emptying the drainage bag, make sure the drainage spout does not touch a contaminated surface.
  • Teach the patient the importance of personal hygiene—especially the importance of careful cleaning after having a bowel movement—and thorough, frequent hand hygiene.
  • Promptly communicate any signs or symptoms of infection. These include a burning sensation and irritation at the meatus, cloudy urine, a strong odor to the urine, an elevated temperature, and chills.
  • Remember to keep the collecting bag lower than the bladder to promote drainage.
  • Patients who require long-term use of an indwelling catheter may experience self-care practice and catheter challenges. Patients need educational interventions to address fluid intake, bowel management, hygiene, and self-monitoring/management, including potential adverse events.
36
Q

How often should you change an indwelling catheter?

A

-Change indwelling catheters only as necessary. The interval between catheter changes varies and should be individualized for the patient, based on clinical symptoms: catheter encrustations, obstruction, leakage, bleeding, and CAUTIs.

37
Q

What are some characteristics of urine that alert for an infection?

A

Turbidity = cloudiness

38
Q

Cystoscopy =

A

Inserting a scope in our urethra and trying to view the bladder visually

39
Q

Intravenous pyelogram =

A

Insert IV and inject a dye. Dye goes through the bloodstream and will end up in your urinary system for elimination.

40
Q

Retrograde pyelogram =

A

Insert a catheter and they inject a dye. Then the dye goes to the bladder and then to the ureter and then to the kidney.

41
Q

Interventions focused on urine elimination:

A
  • Maintaining normal voiding habits (go pee when you have to pee)
  • Assist to void when there is an urge to void.
  • Provide privacy and assure normal voiding position.
  • Promoting fluid intake of at least 6-8 glasses daily.
  • Avoid caffeine containing, high sodium, and high sugar beverages (all can cause dehydration)
  • Encourage pelvic floor exercises such as kegels.
42
Q

Q

Women are more susceptible to UTIs
True/False

A

TRUE!

  • people with female genitalia are more vulnerable due to shorter urethras and the close proximity of the vagina to the rectum

Q

Treatment for UTIs include:

A

Antibiotics, fluids, assess characteristics of urine, dry from front to back, void immediately after intercourse, avoid baths, wear cotton underwear, not lotions or antibacterials to be used down there

45
Q

What labs/ testing needs to be done if a UTI is suspected and when does it need to be done?
