Exam 3 Flashcards
Normal urinary elimination maintains the concentration of ions needed for what 3 things?
- Neuro and muscle function
- Bone strength
- Cellular regeneration
- Maintains homeostatic regulation of bp for adequate circulation of oxygen and nutrients
What organs are part of the Upper urinary tract?
Kidneys and Ureters
What is part of the lower urinary tract
- Urinary bladder
- Urethra
- Pelvic floor
what is the step-by-step process of emptying the bladder?
Urine collects in the bladder –> Pressure stimulates stretch receptors –> Transmit impulses to the voiding reflex center of the spinal cord –> If time, the place is appropriate –> Conscious part of the brain relaxes external urethral sphincter muscle –> Urination occurs
Patterns of voiding (5 things)
- Vary by individual
- Everyone should void at least every 6 hours
- Most people void 6–7 times/day
- 4 to 10 times a day is considered normal
- Amount varies based on age, weight, daily fluid intake, types of fluid consumed, and meds (0.5 – 1.0 mL/kg/hr)
What are the factors that affect urinary elimination (6 things)
- Fluid and food intake
- Muscle tone
- Psychosocial factors
- Pathologic conditions
- Surgical and diagnostic procedures
- Medications
What causes alteration in urinary elimination?
- older or younger?
- system problem (hint)
- 2 others
- Age-related changes
- Acute/chronic diseases and their treatment
- pregnancy-stress incontinence
- Arthritis-functional issues
What can polyuria cause?
What is it caused by?
- Can cause excess fluid loss –> intense thirst, dehydration, and weight loss
- Caused by disease: diabetes mellitus, diabetes insipidus and kidney disease
What leads to polydipsia; what is it associated with?
compulsive intake of excessive amounts of fluid. This is associated with polyuria
What is Anuria
When you urinate 100 mL or less a day
What is Oliguria?
What is the amount range?
What can it signal?
Does it need to be reported?
Scant urine production
- <400 ml/day or 30ml/hr
- may signal impending renal failure
- needs to be reported
What are the 4 things that cause changes in urinary frequency?
- Inc. total fluid intake
- UTI
- stress
- pregnancy
What causes a sudden strong desire to void regardless of the volume of urine present
- unstable bladder contractions
- psychologic stress
- irritation of the urethra
- poor external sphincter control
What is Dysuria?
What are the causes?
Pain or difficulty voiding
Causes:
- stricture of the urethra, UTI, injury to the bladder/urethra
- Often individuals express the need to “push” to void or a “burning” during or after urination
What is urinary hesitancy and what is it associated with?
delayed or difficulty in initiating the void and is often associated with dysuria
What is a neurogenic bladder?
- What is it often due to?
- Does not perceive bladder fullness
- Unable to control urinary sphincters
- The bladder can be flaccid and distended, spastic with frequent involuntary urination
- Often due to a malfunction caused by damage to the spinal cord
Factors related to lower urinary tract symptoms
- Constipation
- IBS
- Sexual activity
- Delayed/premature voiding
What are nonmodifiable risk factors for alteration in urinary elimination
- Physical, cognitive, or developmental disability
- Family Hx of incontinence
What are genetic considerations for alteration in urinary elimination
- Spina bifida
- Myelomeningocele
What diseases related to aging, alter the urinary elimination process
- Parkinson disease
- Alzheimer’s disease (changes in cognitive function)
The increase in ______ and ________ increases with age
Urgency; frequency
What is part of the nursing assessment related to urinary elimination
- Check voiding pattern
- Description of urine and any changes (color, odor, sediment, clarity, pus blood)
- urine elimination problems (change in pattern or pain)
What is the physical examination for urinary elimination
- Abdomen
- Soft tissues of genitalia, perianal areas
- Urethral meatus
- Feces and urine
- Fluid volume status
What are anticholinergic medications
they reduce urinary frequency, treat incontinence
