Study Notes
Bladder Elimination
- Normal bladder elimination: 250-400 mL of urine, voluntary control, intact nerve conduction
Factors Affecting Bladder Elimination
- Fluid and food intake
- Muscle tone
- Surgical and diagnostic procedures
- Medications
Risk Factors for Bladder Elimination Issues
- Age
- Arteriosclerosis, chronic conditions, surgery, genetics
Alterations in Bladder Elimination
- Polyuria: production of abnormally large amounts of urine
- Polydipsia: compulsive intake of excessive amounts of fluid
- Anuria: less than 100 mL a day (no urine)
- Oliguria: less than 400 mL a day (low urine output)
- Frequency: urinating often
- Urgency: strong urge to urinate
- Nocturia: urinating 2 or more times a night
- Dysuria: trouble urinating
- Hesitancy: hesitating to urinate
- Neurogenic bladder: unable to sense the feeling to urinate
Observation and Patient Interview
- Look for: anxiety, odor, absorbent items
- Voiding pattern: frequency, volume, color of urine, pain, issues with voiding
- Investigate other factors influencing urinary elimination
Physical Examination
- Palpation of abdomen
- Flank pain
- Skin turgor
- Inspection of any urine or fecal material
- Genitalia
Diagnostic Tests
- Urine studies: culture, sensitivity, urinalysis
- Bladder scan: evaluates bladder emptying
- Radiologic examinations: retrograde pyelography
- Cystoscopy: allows for direct visualization of bladder wall
- Imaging: KUB radiograph, CT, MRI, US, etc.
- Kidney biopsy
Independent Nursing Interventions
- Monitoring intake and output
- Catheter care
- Incontinence care
- Urine specimen collection
- Patient teaching
Collaborative Therapies
- Treatment team can consist of many members
- Referrals may need to be made
- Pharmacologic therapy can be initiated
- Dialysis can be used for severe injury or disease progression
Anticholinergics (Muscarinic Antagonists)
- Examples: oxybutynin
- MOA: blocks receptors in the detrusor muscle of the bladder preventing contractions, and the urge to void
- Adverse effects: blurred vision, constipation, dry mouth, anhidrosis, photophobia, dry eyes, tachycardia, hallucinations, confusion
- Nursing considerations: contraindicated in patients with urinary retention, GI obstruction
Cholinergics (Muscarinic Agonists)
- Examples: bethanechol
- MOA: Stimulates bladder contraction, and assists with voiding
- Adverse effects: cramping, other GI symptoms, diaphoresis, headache, nausea, bradycardia, hypotension, bronchoconstriction
- Nursing considerations: do not give patients with GI or urinary tract obstruction, asthma, bradycardia, hypotension, or Parkinson Disease.
Bowel Elimination
- Normal bowel elimination: soft, formed stool; frequency is individualized
- Diet should include fiber
- Irregular eating patterns can alter bowel elimination patterns
- Spicy foods and high sugars can lead to diarrhea
- Activity and pain can also impact bowel elimination
Factors Affecting Bowel Elimination
- Fluid and food intake
- Activity
- Pain
- Medications
Risk Factors for Bowel Elimination Issues
- Age
- Sex
- Chronic illness
- Immobility
Alterations in Bowel Elimination
- Diarrhea: passage of liquid feces with increased frequency, results in loss of fluid can lead to dehydration
- Flatulence: presence of excess gas leading to inflation and bloating
- Diverticulitis: results from inflamed diverticula can obstruct bowel
- Bowel obstruction: occurs when the contents of the intestine are unable to move through the intestine
Observation and Patient Interview
- Look for any anxiety, odor and any absorbent items
- Defecation pattern: frequency, consistency of stool, pain
- Investigate other factors influencing defecation: diet, exercise, medications, stress, ostomy
Physical examination
- Auscultate, palpate, percuss
- Inspect abdomen, gently palpate abdomen (be careful with pressure)
Diagnostic Tests
- Blood and fecal tests
- Endoscopy
- Biopsy
- Imaging (e.g. KUB radiograph, CT scan, MRI, etc.)
Newborns and Infants
- Meconium is the first stool passed, which is thick and tarry
- Immature intestines can lead to difficult stool passage
Toddlers
- Control of bowel elimination generally starts around 2-3 years old
School-Age Children/Adolescents
- Bowel elimination should be under control by this age
Pregnant Women
- Hormonal changes can impact bowel elimination
- Progesterone can lead to sluggish bowel elimination
- Enlarging uterus puts pressure on the bowels
- Increased gastric reflux
- Hemorrhoids can develop
- Postpartum risks also exist
Older Adults
- Nearly all experience constipation
- Poor intake, reduced activity, and medications contribute to constipation
- Declining renal function
- Inability to concentrate urine
Antidiarrheal Medications
- Examples: loperamide
- MOA: blocks action of acetylcholine, slowing motility of intestines
- Adverse effects: electrolyte imbalance with prolonged use
- Nursing considerations: avoid use with patients who have severe dehydration, liver or renal disorders, or glaucoma
Prokinetic Agents
- Examples: metoclopramide
- MOA: augments acetylcholine, increasing upper GI motility and peristalsis
- Adverse effects: tardive dyskinesia, extrapyramidal symptoms, restlessness, anxiety, sedation, diarrhea, increased seizure risk
- Nursing considerations: use cautiously with older adults and children, don’t use with bowel obstruction, perforation or hemorrhage
Stool Softeners/Surfactants (Laxatives)
- Examples: docusate sodium
- MOA: lowers surface tension of stool allowing water to penetrate, soften, and allow for easier passing of stool
- Adverse effects: electrolyte imbalance with prolonged use
- Nursing considerations: bowel movement should occur within 3 days, don’t use with bowel obstruction
Osmotic Laxatives
- Examples: magnesium hydroxide, lactulose
- MOA: draws water into the intestine, increasing the mass of stool and causing peristalsis
- Adverse effects: abdominal cramping, diarrhea, fluid and electrolyte imbalance, dehydration
- Nursing considerations: bowel movement should occur within 3 days, can interact with some antibiotics
Stimulant Laxatives (Cathartics)
- Examples: bisacodyl, senna
- MOA: stimulates intestinal peristalsis and increases the volume of water and electrolytes in the intestine
- Adverse effects: stomach discomfort, nausea, diarrhea, cramps, fluid and electrolyte loss
- Nursing considerations: bowel movement should occur within 12 hours, don't take with milk or antacid, avoid if bowel obstruction
Bulk-Forming Laxatives
- Examples: psyllium
- MOA: supplemental fiber to soften stool
- Adverse effects: potential for gas and abdominal bloating
- Nursing considerations: drink plenty of fluids with this type of laxative, do not use with bowl obstruction or narrowing of the bowel
