question
Urinary incontinence
answer
inability to voluntarily control urine flow as bladder pressure exceeds urethral resistance
question
Stress incontinence
answer
involuntary loss of urine that occurs when the bladder cannot handle increased amounts of abdominal pressure, due to weakness or urethra and surrounding muscles small amounts of urine typically leak during exercise, coughing, sneezing, laughing most common type seen
question
Urge Incontinence
answer
Loss of urine with an abrupt and a strong desire to urinate commonly due to a sudden involuntary, uncontrolled contraction of the detrusor muscle a symptom of overactive bladder instead of relaxing during urination, this muscle becomes very hypertonic
question
Mixed incontinence
answer
combination of stress and urge most often seen in elderly women
question
Overflow incontinence
answer
bladder becomes overfilled because sensation to void is not felt by client detrusor muscle is weak and underactive and/or the urethra is obstructed bladder cannot be completely emptied: spills over behaviors: constant dribbling, urgency, frequent urination often due to neurological deficits, medication side effects, bladder neck obstruction from an enlarged prostate or injury, fecal impaction

leakage of urine R/T physical, environmental, or psychologic cause client can't physically get to the bathroom R/T immobility or restraint client is depressed/ has dementia need help getting to the bathroom
question
Total incontinence
answer
result of neurologic disease with dysfunction of nerves controlling bladder may include urge or overflow
question
Reflex incontinence
answer
related to neurologic abnormalities, which cause the detrusor muscle to contract abnormally spinal injuries
question
Causes (etiology) or urinary incontinence:
answer
UI occurs when bladder pressure exceeds urethral closure pressure Bladder fails to contract at the appropriate time or contracts inappropriately (detrusor muscle instability) Urethra may open or close inappropriately (urethral sphincter weakness) Abnormalities outside the bladder and urethra Pelvic floor ligament weakness
question
DRIP:
answer
D: delirium, dehydration, depression R: restricted mobility, rectal impaction I: infection, inflammation, impaction P: polyuria, polypharmacy
question
medical and nursing interventions for the client with urinary incontinence. Can prescribe medications
answer
Stress: in incontinence, the bladder pressure is greater than urethral resistance give meds to increase resistance of urethra and increase urethral pressure: makes bladder pressure less than urethra Urge: in incontinence, the bladder contracts involuntarily Give meds to control hypertonic bladder and increase bladder capacity These meds reduce bladder contractions Reflex/overflow Give meds to enhance bladder contractions and/or decrease urethral resistance
question
medical and nursing interventions for the client with urinary incontinence. Change the patient's diet
answer
Weight reduction for obese clients to reduce abdominal pressure Avoid caffeine, alcohol, sugar substitutes These are bladder stimulants Avoid constipating foods
question
medical and nursing interventions for the client with urinary incontinence. Introduce exercise therapy
answer
These are the first line of treatment for Stress Incontinence; also used to treat urge and mixed incontinence Pelvic muscle exercises (PME) Kegel exercises Strengthen the pelvic floor

answer
Timed voiding Habit retraining Prompted voiding Bladder retraining
question
medical and nursing interventions for the client with urinary incontinence. Anti-incontinent devices
answer
For women: Intra-vaginal devices (pessary, balloons) Applies pressure on the urethra For men: urethral clamps or plugs
question
medical and nursing interventions for the client with urinary incontinence. Containment devices
answer
Incontinence pads and briefs Urinary catheterization
question
medical and nursing interventions for the client with urinary incontinence. Surgical management
answer
Suggested for certain types of stress incontinence Bulking agents: collagen or silicone bead injections are inserted around the urethra Implantation of an artificial urinary sphincter Bladder neck suspension procedures These procedures will pull the neck up and/or restore normal urethro-vesico angle Stabilizes the bladder neck
question
how to protect the skin of an incontinent patient
answer
Provide hygiene immediately after incontinence Use absorptive pads (CHUX) to wick away moisture and provide a quick drying surface to the skin Use gel diapers More absorptive than disposable cellulose or cloth diapers Allow pt to lie on top of pad and let uncovered areas of skin dry Reposition pt to allow other skin surfaces to dry Check these patients regularly since they are at an increased risk for skin breakdown and pressure ulcers
question
complications of altered bladder elimination
answer
Can cause UTIs , skin breakdown, social isolation R/T embarrassment, body image disturbance
question
bladder training
answer
Bladder retraining: attempt to increase volume that the bladder can hold each time To start, encourage the pt to void every 30 minutes to 1 hour, then gradually increase bladder capacity by extra 30 min-1 hour The goal is 2-3 hours
question
pathophysiology of cystitis
answer
and inflammation of urinary bladder. It's patho-phys is on a CELLULAR level with an organism. It's a disturbance in the integrity of the urothelial cells of the bladder and/or urethra, which allows the organism to invade. These cells produce mucin which protects the bladder cells from the effects of urine sitting there all the time. The bacteria attaches to bladder cells and cells commit suicide and slough off. SOME bacteria worse and send out small projections called "TYPE 1 PILI" that are tipped with a protein that allows them to lock into receptors on bladder lining -- they borough in and stay there. This is why many think REPEATED infections.
question
pathophysiology of pyelonephritis
answer
The inflammation & bacterial infection of renal pelvis. When the bladder does not empty fully due to REFLUX of URINE and/or UNTREATED CYSTITIS, so organisms invade renal pelvis.
question
Signs and symptoms of cystitis (bladder infection) and urethritis (urethra infection)
answer
May be asymptomatic. Urgency to void * Burning with urination, dysuria * Slight to gross hematuria. Frequency= often, small amt's. * Pain (Cystitis) - tender suprapubic area or low back pain. Urethritis - reddened urethra, burning, pruritus. Bladder distention. Hazy ---> cloudy urine (maybe). Foul-smelling urine (maybe). Elderly clients with UTI are at a greater risk for UROSEPSIS, a generalized infection caused by GRAM NEGATIVE BACTEREMIA.
question
Signs and symptoms of pyelonephritis:
answer
Inflammation - Scar tissue formation with healing and decreased renal tubule reabsorption & secretion and impaired renal function Fever, chills - often spike high fever-- 102 - 103o Malaise & fatigue Nausea/vomiting, maybe Flank &/or abd. pain - assess CVA (costal-vertebral angle ) Pain on urination (dysuria); hematuria. Usually have cystitis (symptomatic or asymptomatic) May have underlying G/U obstruction.
question
Acute pyelo.
answer
----> renal impairment
question
Chronic pyelo.
answer
----> renal failure.
question
Nursing diagnoses for patients with UTI
answer
a.) Impaired urinary elimination b.) Deficient Knowledge R/T methods of prevention and treatment protocols
question
What is the purpose and function of urothelial cells?
answer
produce mucin mucin is a mucopolysaccharide which normally protects the bladder cells from the affects of urine sitting there all the time
question
Why are the elderly at higher risk for UTI?
answer
increased relaxation of pelvic structures: don't empty bladder fully decreased thirst: drink less water decreased immune system chronic diseases: stroke, diabetes
question
Interventions Medications
answer
antiseptics: bacteriostatic: raise urine acidity so bacteria can't grow antibiotics: bacteriocidal anti-infectives: may cause crystalluria and kidney stones
question
Interventions Fluids and diet
answer
increase fluids to 2-3L per day cranberry juice
question
Interventions pain relief
answer
urinary analgesics: pyridium: anesthetizes urinary mucosa antispasmodics: anticholinergics: decrease bladder spasms and promotes complete bladder emptying
question
Prostate gland
answer
a gland surrounding the neck of the bladder in males, releasing prostatic fluid
question
Seminal vesicle
answer
a pair of glands that open into the vas deferens near its junctions with the urethra and secretes many of the Components of semen
question
Erectile tissue
answer
numerous vascular spaces that may become engorged with blood
question
Epididymis
answer
a highly convulated duct behind the testis along which the sperm passes through the vas deferens
question
Testis
answer
an organ that produces spermatozoa
question
pathophysiology of BPH
answer
Prostate gland enlarges by abnormally increasing the number of cells (hyperplasia) & glandular tissue. As the gland enlarges, it presses on the urethra & bladder & obstructs the flow of urine. Can lead to urinary retention, reflux, bladder trabeculation, hypertrophy, & hyperirritability, reflux to ureter & renal pelvis, with hydronephrosis. In time, bladder wall can become non-compliant & hypotonic...---> resulting in post-residual voids & increasing chance of infection.
question
signs & symptoms indicative of BPH
answer
Urinary urgency & frequency - from hyper-irritable bladder. Nocturia Hesitancy in starting urination Decrease in size & force of urine stream Terminal dribbling Sensation of incomplete bladder emptying S/S of UTI secondary to stasis of urine.
question
pre-operative teaching related to the patient with a transurethral resection of the prostate (TURP)
answer
Urinary drainage must be restored prior to surgery → coude (curved tip) catheter may be inserted with lidocaine gel (acts as lubricant and local anesthesia); maintain sterile field Antibiotics are administered before invasive surgery Encouraging a high fluid intake (2-3L/day) helpful in managing infection Educate patient that surgery may affect sexual function → retrograde ejaculation (ejaculate goes up into bladder) which decrease orgasmic sensation but is not harmful because it is eliminated during next urination
question
post-operative teaching related to the patient with a transurethral resection of the prostate (TURP)
answer
Bladder irrigation Blood clots are expected after surgery, but if there are large amounts of bright red blood in urine, it can indicate hemorrhage which can occur from displacement of the catheter, dislodgement or a large clot or increases in abdominal pressure Bladder spasms occur as a result of irritation of the bladder mucosa from the insertion of the resectoscope, presence of a catheter, or clots leading to obstruction of the catheter Catheter removal is often 2-4 days after surgery and patient should urinate within 6 hours after removal. If he cannot, reinsert a catheter for a day or two Sphincter tone may be poor immediately after catheter removal, resulting in urinary incontinence or dribbling Strengthen via Kegel exercises 10-20 x/hour Encourage patient to practice starting and stopping the stream several times during urination If continence is not improved after 12 months, refer patient to continence clinic You can instruct patient to use penile clamp, condom catheter or incontinence pads to avoid embarrassment from dribbling Observe patient for signs of post-operative infection A diet high in fiber facilitates passage of stool (prevent patient from straining while having BM → straining increases intraabdominal pressure which can lead to bleeding at post-op site)
question
Explain the rationale for bladder irrigation following a TURP
answer
Bladder irrigation is typically done to remove clotted blood from the bladder and ensure drainage of urine
question
continuous & intermittent bladder irrigation
answer
Intermittent or continuous urinary catheter irrigations maintain catheter patency by keeping the bladder clear and free of blood clots or sediment
question
assessments & nursing interventions specific to continuous bladder irrigation (CBI)
answer
Rate of infusion is based on color of drainage Ideally should be light pink without clots Continuously monitor the inflow and outflow of irrigant If outflow is less than inflow, assess the catheter patency for kinks or clots If outflow is blocked and patency cannot be reestablished by manual irrigation, stop the CBI and notify the physician
question
To calculate proper I & O with bladder irrigation:
answer
for the output, subtract the amount of irrigant
question
Discharge instructions to provide after TURP:
answer
no lifting, driving, strenuous activities for 2-3 weeks no straining with BM encourage fluids to 12-14 glasses a day avoid bladder irritants
question
complications of TURPS:
answer
dribbling and incontinence are normal initially bleeding decreased urinary stream UTI
