Lecture 12 Flashcards
Urinary and Bowel Elimination
What is micturition?
The entire process of urinary elimination including the urinary and nervous systems
when the brain gives the bladder permission to empty, what happens?
Bladder contracts and urinary sphincter relaxes allowing the urine to empty
which kidney is higher than the other and why?
The left is higher than the right because of the anatomical position of the liver
Nephrons remove waste products from the blood and play a major role in the regulation of…
Fluid and electrolyte balance
what part of the kidney is the ureter attached to?
the renal pelvis
what is the normal range of urine production everyday?
1 to 2 L/day
How do the kidneys help regulate BP?
Via the renin-angiotensin system and the release of aldosterone and prostacyclin
The kidneys affect calcium and phosphate regulation by…
producing a substance that converts vitamin D into its active form
what are the two parts of the urinary bladder?
A fixed base called the trigone and a distensible body called the detrusor
is the release of urine voluntary or involuntary?
voluntary
how long is the male urethra?
about 18 to 20 cm (7 to 8 in.) long
how long is the female urethra?
about 3 to 4 cm (1 to 1.5in.) long
Why are females at increased risk for UTI?
close access to bacteria in the perineal area
what areas of the brain control urination(4)?
1) Cerebral cortex
2) Thalamus
3) Hypothalamus
4) Brainstem
There are two micturition centers in the spinal cord. What do they coordinate?
1) Inhibition of bladder contraction
2) Bladder contractility
What the bladder fills to approx. (BLANK) most people experience a strong urge to urinate.
400 - 600mL
when the time and place is appropriate, the brain sends a message to…
relax urinary sphincter and contract the bladder resulting in voiding
When the time and place is inappropriate, the brain sends a message to the micturition centers to…
contract the urinary sphincter and relax the urinary bladder (holding it)
children cannot voluntarily control voiding until…
18-24 months
readiness for toilet training includes the ability to:
1) Recognize the feeling of fullness
2) To hold urine for 1 - 2 hours
3) Communicate the sense of urgency
URINARY
Older adults may experience(4):
1) Decreased bladder capacity
2) Increased bladder irritability

Increased rate of urinary incontinence in older adults is due to(2):
1) Chronic illness
2) Factors that interfere with mobility, cognition, and manual dexterity
When it comes to privacy during voiding, what is acceptable among cultures?
Americans and many others expect bathrooms to be private while many other cultures accept communal toilet facilities
Apart from personal preference, what else can dictate who is acceptable to assist in elimination practices?
religious and cultural norms
social expectations (e.g. school recesses, work breaks) can interfere with timely (BLANK)
voiding
Anxiety can impact the bladder emptying due to:
inadequate relaxation of the pelvic floor muscles and urinary sphincter
Depression can decrease the desire for…
urinary continence

Diabetes mellitus, multiple sclerosis, and stroke can alter bladder contractility and the ability to sense bladder filling. What will these patients experience(2)?

Some conditions can affect a patient’s ability to make it to the toilet on time. list 4.
1) Arthritis
2) Parkinson’s disease
3) Dementia
4) Chronic pain syndromes
Spinal cord injury or intervertebral disk disease above S-1 can cause(2):
1) Loss of bladder control
2) Impaired coordination between bladder contracting and urinary sphincter
Prostatic enlargement can cause
urinary retention
Trauma during abdominal or pelvic surgery sometimes obstructs urine flow. What does this require?
Indwelling urinary catheter
What can anesthetic agents do to the urinary system?
It can decrease bladder contractility and/or sensation of bladder fullness causing urinary retention
TRUE OF FALSE: Urine color can not change due to drugs
F. some drugs change the color of urine
What color does phernazopyridine or Pyridium change urine to?
What is it for?
Changes urine orange and it is used for bladder discomfort
What color does riboflavin and vitamin b2 change urine to?
Intense yellow
Diuretics can increase urine output by preventing…
reabsorption of water and certain electrolytes
what can Anticholinergics do to the urinary system?
Increase the risk of urinary retention by inhibiting bladder contractility
what side-effect can hypnotics and sedatives have on the urinary system?
they can reduce the ability for a patient to recognize and act upon the urge to void
a cystoscopy may lead to localized trauma of the urethra resulting in…
transient (1 to 2 days) dysuria and hematuria
What is dysuria?
pain while urinating
what is hematuria?
blood in urine
What are factors that influence urination(9)?
GSPPFPSMD
1) Growth and development
2) Sociocultural factors
3) Psychological factors
4) Personal habits
5) Fluid intake
6) Pathological conditions
7) Surgical procedures

what are urinary tract infections characterized by?
characterized by location
what is the upper urinary tract?
kidneys and ureters
What is the lower urinary tract?
bladder and urethra
What is bacteriuria?
presence of bacteria in the urine
bladder infections should be treated with what?
antibiotics
infection of the bladder can lead to what(2)?
1) Pyelonephritis (upper urinary tract infection)
2) Bacteremia or Urosepsis (life-threatening bloodstream infection

A health care provider may suspect that a patient is experiencing urinary retention when the patient has:
A. large amounts of voided cloudy urine.
B. pain in the suprapubic region.
C. spasms and difficulty during urination.
D. small amounts of urine voided two to three times per hour.
D

A. abnormal defecation.
B. constipation.
C. fecal impaction.
D. fecal incontinence.
B
To maintain normal elimination patterns in the hospitalized patient, you should instruct the patient to defecate 1 hour after meals because:
