Q

For infection to occur in the Lower urinary Tract

A

Bacteria must gain access to the bladder, attach to and oclonize the epithelium of the urinary tract to avoid being washed out with voiding, evade host defense mechanisms and initiate inflammation

Lower UTIs: Acute short term treatment regimen typically lasts
3-7 days
37
Upper UTI: Pyeloephritis cause involves either
the upward spread of bacteria from the bladder or spread from systemic sources reaching the kidney via the blood stream

Upper UTI: Nursing Management for Chronic Pyelonephritis: How much fluid is encouraged?
3-4 L. Dilutes the urine, decrease burning on urination, and prevent dehydration
50
What is Stress Incontinence?
Involuntary loss of urine through an intact urethra as result of sneezing, coughing, or changing position
51
Stress Incontinence predominately affects who
women who have had vaginal deliveries and is throught to be result of decreasing ligament and pelvic floor support
52
What is Urge Incontinence?
Involuntary loss of urine associated with a strong urge to void that cannot be suppressed
53
Precipitaitng Factor of URge Incontinence?
Uninhibited detrusor contraction
54
What is Functional Incontinence?
Instances in which lower urinary tract function is intact but other factors, such as severe cognitive impairement, make it difficult for the patient to identify the need to void or physical impairments make it difficult to reach toilet in time
55
What is Iatrogenic Incontinence?
Involuntary lsos of urine due to extrinsic medical factors, prodominately medications
56
What is Mixed Urinary Incontinence?
Encompases several types of urinary incontinence, is involuntary leaking associated with urgency and also with exertion, effort, sneezing, or coughing
57
What can proboke the onset of urinary incontinence?
Acute UTI, infection, constipation, decreased fluid intake, and change in chronic disease pattern
58
Medical management types for incontinence?
Behavioral Therapy Pharmacologic Therapy Surgical Management
59
Incontinence: What is the cornerstone of behavioral intervention for addressing symptoms of stress, urge and mixed incontinece?
Pelvic floor muscle exercises (Kegel exercises)
60
Chronic urine retnetion leads to
overflow incontinence (involuntary urine loss associated with overdistention of the bladder)
61
Urinary retention may result from
diabetes, prostatic enlargement, urethral pathology, trauma, pregnancy, or neurologic disorders
62
The retention of urine can lead to
chronic infection that predispose patient to renal calculi , pyelonephritis, sepsis or hydronephrosis
63
Additional measures to promote urinary elimination include
applying warmth to relax the sphincter, giving the patient hot caffeine free beverage, and offer encouragement
64
Urinary Retention: When the patient cannot void, what technique is performed?
Bladder scanning is used to assess for distension then straight catheterization is used to prevent overdistention of the bladder
65
Urinary Retention: In the case of prostatic obstruction, what will be done
insertion of suprapubic cather (catheter inserted through a small abdominal incision into the bladder)
66
Urinary REtention caused by
adults 60 years and older may have 50-100 mL of urine left in bladder Postoperative spasms Diabetes, prostatic enlargement, urethral pathology, truma, pregnancy Medications
67
Neurogenic Bladder: This is a
dysfunction frfom a disorder or dysfunction of the nervous system that leadss to urinary incontinence
68
Neurogenic Bladder: caused by
spinal cord injury, spinal tumor, herniated vertebral disc, multiple sclerosis, congential disorders, infections, or complications of disabetes
69
Neurogenic Bladder: Two types of neurogenic bladder?
Spastic (reflex) and flaccid bladder
70
Neurogenic Bladder: What is the more common type?
Splastic bladder, and caused by any spinal cord lesion above the voiding reflex arc
71
Neurogenic Bladder: Spastic bladder empties on
reflex,with minimal or no controlling influence to regulate its activity
72
Neurogenic Bladder: Flaccid bladder caused by
a lower motor neuron lesion, commonly resulting from trauma
73
Neurogenic Bladder: Flaccid bladder being recognized in patients with
diabetes
74
Neurogenic Bladder: Wha thappens in Flaccid Bladder?
Bladder continues to fill and become sgreatly distended and overflow incontinence occcurs. Muscle does not contract forcefully.
75
Neurogenic Bladder: Assessment fo rhtis?
Measurement of fluid intake, urine output, and residual volume Urinealysis Assessment of sensory awareness Comprehensive urodynamic studies performed
76
Neurogenic Bladder: Most common complication is
infection resulting from urinary stasis and catheterization. Others include renal calculi, impaired skin integrity, urinary incontinence or retention
77
Neurogenic Bladder: Specififc interventions include
continuous, intermittent, or self-catherization ; the use of an external condom catheter ; diet low in calcium ; encouragement of mobility and ambulation
78
Catherization: When urine cannot be eliminated naturally and must be draind artifially, what is done?
Catheters inserted into bladder, ureter, or renal pelvis
79
Catherization: What are the four types of catheters/
Indwelling Suprapubic Condom Indwelling
80
Catherization - Indwelling Catheters: What catheter commonly used fter transurethral prostate surgery?
Triple-Lumen Catheter
81
Catherization - Indwelling Catheters: What is the triple-lumen catheter
it is a triple lumen indwelling urethal catheter attached to a closed sterile drainage system .
82
Catherization - Indwelling Catheters: Triple Lumen Catheter purpose of three ports?
Urinary drainage through one channel Retention of balloon in inflated with water or air in second Bladder continuously irrigated with sterile irrigating osolution through third
83
Catherization - Indwelling Catheters: Why should the bag be lower than the patietns bladder?
Does not allow urine to flow back into the bladder
84
Catherization - Suprapubic Catheter: These catheters allow bladder drainage by
inserting a catheter or tube into the bladder through a subprapubic incision or puncture. Catheter or drainage tube then threaded into bladder
85
Catherization - Suprapubic Catheter: This may be a temporary measure to fivert flow of urine form the urethra when the
urethral route is impasable, after gynecologic or other abdominal surgery when dysfunction is to occur, or pelvis factures
86
Catherization - Suprapubic Catheter: This may be maintained continuously for
several weeks
87
Catherization - Suprapubic Catheter: When patietns abaility to pee is tested, catheter is
clamped for 4 hours . After voiding, catheter is unclamped and residual urine is measure
88
Catherization - Suprapubic Catheter: To avoid encrustation, patient requires
liberal amounts of fluid
89
Catherization - Suprapubic Catheter: Other potential problems include
formation of bladder stones, acute or chronic infections, and problems colelcting urine
90
Catheterization: Signs and symptoms of UTI?
Cloudly, malodorous urine, hematuria, fever, chills, anorexia, and malaise
91
Catheterization: When an indwelling urinary catheter is in place , what muscle does not be used?
Detrusor muscles do not actively contract the bladder wall to stimulate emptying. They then may not respond to bladder filling resulting in urine retention or urinary incontinence
