206- Bladder & Bowel Elimination

Variables Affecting Urinary Elimination

Factors that influence a patient’s ability to urinate normally, including fluid intake, disease, medications, and psychological state.
Ex: A patient drinking coffee frequently may have urgency and frequency due to bladder irritation.

Effect of Fluid & Diet on Urination

Increased fluid intake increases urine output; caffeine and alcohol irritate the bladder and increase frequency.
Ex: A patient with nocturia should avoid caffeine in the evening.

Pathological Causes of Urinary Changes

Diabetes, stroke, MS, and BPH(enlargement of prostate) affect bladder function (retention or overactivity).
Ex: A male patient with BPH may report weak stream and dribbling due to obstruction.

Neurological Impact on Bladder Function

Spinal cord injuries (above S1) impair bladder control and coordination.
Ex: A spinal cord injury patient may have reflex incontinence without awareness.

Psychological Effects on Urination

Anxiety causes urinary retention; depression decreases motivation for continence.
Ex: A hospitalized patient unable to void may need relaxation and privacy.

Medication Effects on Urinary Elimination

• Diuretics → increase urine output

• Anesthesia/opioids → urinary retention
  Ex: Post-op patient unable to void likely has anesthesia-related retention.

Stress Urinary Incontinence

Leakage with increased abdominal pressure (coughing, sneezing, laughing).
Ex: A patient leaks urine when laughing → stress incontinence.

Urge Urinary Incontinence

Sudden strong urge followed by involuntary leakage.
Ex: Patient cannot reach bathroom in time after feeling urge.

Overflow Urinary Incontinence

Constant dribbling due to bladder overdistention and incomplete emptying.
Ex: A patient with BPH has frequent dribbling and a distended bladder.

Functional Urinary Incontinence

Inability to reach the toilet due to physical or cognitive limitations.
Ex: A patient with arthritis cannot unbutton pants quickly enough.

Reflex Urinary Incontinence

Involuntary urination without awareness due to neurological damage.
Ex: Spinal cord injury patient voids without feeling urge.

Nursing Interventions for Incontinence

Timed voiding, Kegel exercises, fluid restriction before bed, environmental modifications.
Ex: Offering toileting every 2 hours reduces episodes of incontinence.

Promoting Normal Urination

Provide privacy, proper positioning, and time; stimulate with running water.
Ex: Sitting a female patient upright helps initiate voiding.

Measuring Urine Output (Ambulatory vs Bedbound)

• Ambulatory → urine hat

• Bedbound → bedpan/urinal

• Foley → drainage bag measurement
  Ex: Accurate I&O (intake&output) is critical in critically ill patients.

Normal vs Abnormal Urine Characteristics

• Normal: pale yellow, clear

• Dark: dehydration/liver issues

• Cloudy/foul: infection
  Ex: Cloudy, foul urine suggests a UTI

Indications for Catheterization

Urinary retention, sterile specimen, strict I&O, surgery, wound healing.
Ex: A critically ill patient requires Foley for hourly output monitoring.

Intermittent (Straight) Catheter

Single-use catheter for temporary bladder emptying.
Ex: Used to measure post-void residual.

Indwelling (Foley) Catheter

Remains in bladder with balloon for continuous drainage.
Ex: Used in post-surgical patients.

Triple-Lumen Catheter

Used for continuous bladder irrigation (CBI).
Ex: Prevents clot formation after prostate surgery.

Suprapubic Catheter

Inserted surgically through abdomen into bladder.
Ex: Used when urethral catheterization is not possible.

CAUTI Prevention

Maintain sterile technique, keep bag below bladder, no kinks, clean perineum, remove ASAP.
Ex: Keeping drainage bag on the floor increases infection risk.

Urinary Diversions

Alternate urine pathways (e.g., ileal conduit, nephrostomy).
Ex: Used after bladder removal due to cancer.

Stoma Assessment (Urinary Diversion)

Should be red/pink and moist.
Ex: A pale or dark stoma indicates poor perfusion.

Variables Affecting Bowel Elimination

Age, diet, fluids, activity, psychological factors, medications.
Ex: Elderly patients commonly experience constipation due to slowed motility.

Diet & Fluids in Bowel Function

• Fiber→ adds bulk

• Fluids→ soften stool
  Ex: Low fiber + dehydration = constipation.

Effects of Activity on Bowel Elimination

Activity promotes peristalsis; immobility slows it.
Ex: Bedrest patients are at risk for constipation.

Psychological Effects on Bowel Elimination

Stress → diarrhea; depression → constipation.
Ex: Exam anxiety can cause diarrhea.

Medication Effects on Bowel Function

• Opioids → constipation

• Antibiotics → diarrhea

• Anesthesia → paralytic ileus
  Ex: Post-op patient with no bowel sounds may have ileus.

Promoting Regular Bowel Habits

Routine timing, proper positioning, hydration, fiber, activity.
Ex: Encouraging toileting after meals uses gastrocolic reflex.

Proper Position for Defecation

Squatting or sitting upright; elevate HOB 30–45° if immobile.
Ex: Bedpan use requires head elevation to reduce strain.

Enema Positioning

Left Sims’ position with right knee flexed.
Ex: This follows the natural curve of the colon.

Enema Administration Key Points

Warm solution, insert 3–4 inches, hold bag 12–18 inches high.
Ex: Lower bag if patient reports cramping.

Types of Enemas

• Tap water → hypotonic (risk toxicity)

• NS → safest

• Soap suds → irritant

• Hypertonic → pulls fluid in

• Oil → softens stool
  Ex: Avoid hypertonic enemas in dehydrated patients.

Suppository Administration

Insert 1 inch past sphincter; patient remains lying 10–20 min.
Ex: Early movement may expel medication prematurely.

Rectal Catheter Use

Used for gas/liquid stool; limit to 20–30 minutes.
Ex: Prolonged use causes mucosal damage.

Fecal Impaction

Hardened stool in rectum; may cause liquid stool leakage.
Ex: Continuous diarrhea may actually indicate impaction.

Digital Removal Safety Risk

Stimulates vagus nerve → can cause bradycardia.
Ex: Stop procedure if patient becomes dizzy or heart rate drops.

Ileostomy

Output is liquid; high risk for dehydration and skin breakdown.
Ex: Patient needs increased fluids and electrolyte monitoring.

Colostomy

Output varies by location (formed stool in sigmoid).
Ex: Sigmoid colostomy produces near-normal stool.

Ostomy Care

Empty pouch 1/3–1/2 full; ensure snug fit of barrier.
Ex: Overfilled pouch can detach and leak.

Stoma Assessment (Bowel Diversion)

Pink/red and moist = healthy.
Ex: A dusky stoma indicates possible necrosis.
