What are examples of potential bladder irritants that should be avoided?
-Caffeine -Alcohol -Citrus juices -Chocolate -Highly spiced foods
What are risk factors for a UTI?
-Diminished host defenses -Women at more risk (shorter urethra than men, vagina close to rectum), BC (diaphragm and spermicidal agents), sexual intercourse, hormone,etc.) (sexual intercourse promotes "milking" of the bacteria) -Urinary tract abnormalities (Babies born with urinary tract abnormalities that don't allow urine to leave the body normally or cause urine to back up in the urethra); Fistulas and obesity can also contribute to UTIs. -Blockages in urinary tract (Kidney stones or a large prostate) -Urinary retention (BPH (prostate secretes an antimicrobial but when enlarged it does not secrete right and closes off the urethra, tumor, neurogenic bladder are some of the conditions that promote stasis of urine) -Suppressed immune system (DM, HIV, etc.) (Immunosuppressive drugs or cortocosteroids) -Catheterization and other procedures (Urinary catheters, instrumentation, cystoscopic examinations) -Toiletries- excessive bubble bath -Constipation- extra pressure on bladder *Diabetes mellitus, calculi (STONE), hormonal changes, aging, sexual intercourse, Pregnancy, BPH (Benign prostatic hyperplasia - enlarged prostate), catheterized patients, urinary retention, women and elderly, synthetic underwear, wet bathing suits are all risk factors for UTI.

Dicyclomine
What is E. Coli and how does it cause a UTI?
E. coli is an aerobic, gram negative bacterium and is resident flora in the GI tract. When it enters the sterile urinary tract E. coli causes inflammatory reaction and signs and symptoms of infection are manifested. *Others UTI causing microorganisms are Klebsiella, Proteus, Staphylococcus and pseudomonas species.
What is the most common cause of a UTI?
Escherichia coli.
What diagnostic studies could be performed for a UTI?
History and physical examination CBC - Elevated WBC, neutrophils Urinalysis Microscopic UA Urine for culture and sensitivity Imaging studies: CT Urography Intravenous Pyelogram- CONSENT Cystoscopy Ultrasonography *Imaging studies including CT urography or ultrasonography may be done when obstruction suspected.
What is HAI and how does it cause a UTI?
Hospital Acquired Infection Cause is usually due to use of antibiotics (become resistant, do not take full dose), instrumentation and catheterization. *. Most often, hospital-acquired UTIs are under recognized and undertreated, leading to complications such as renal abscesses, arthritis, epididymitis, peri-urethral gland infections, and bacteremia.
What is indicated when a person has Flank pain (UPPER ABD OR BACK AND SIDES), chills, and fever?
Infection of upper tract - Pyelonephritis
Education for a male on a urine sample for a UA (A voided midstream technique; clean catch):
Instruct them to wipe the glans penis around the urethra. The specimen is collected 1 to 2 seconds after voiding begins. *Refrigerate urine immediately on collection. *The urine should be cultured within 24 hours of refrigeration.
Patient education for a person taking the analgesic, Phenazopyridine (Pyridium), for a UTI:
It can stain the urine reddish orange and can be mistaken for blood and may stain underclothing nurse should advise patients to avoid long-term use of Phenazopyridine because it can produce hemolytic anemia.
Patient education for a person taking the analgesic, Methenamine/phenyl salicylate (Urised), for a UTI:
Methenamine/phenyl salicylate (Urised) can also be used in combination with antibiotics and is used to relieve UTI symptoms. Preparations with methylene blue color urine blue or green.
What are examples of the cause diminished host defenses for a UTI?
Normal voiding with complete emptying of the bladder, ureterovesical junction competence, and ureteral peristaltic activity which propels urine forward into the bladder, antibacterial characteristics of urine maintained by an acidic pH (less than 6.0), normal flora in the periurethral area in women and prostatic fluid in men and immune response contribute to the host defenses. An alteration in any of these defense mechanisms increases the risk of contracting a UTI.
An ultrasound or CT scan (CT urogram) may be obtained when?
Obstruction of the urinary system is suspected or UTIs recur (more than 2 or 3 episodes per year).
Pathogens causing a UTI can enter how?
Pathogens enter urinary tract from perineal area or from blood stream (UNCOMMON).
What are nursing management goals for a patient with a UTI?
Patient will have: -Relief from lower urinary tract symptoms -Prevention of upper urinary tract involvement -Prevention of recurrence
What analgesics are given for a UTI?
Phenazopyridine (Pyridium) Methenamine/phenyl salicylate (Urised)
What is a UTI?

What is considered an UPPER UTI and what symptoms are involved?
Pyelonephritis- KIDNEY INFECTION fever, chills, flank pain *upper UTI involves the renal parenchyma, pelvis, and the ureters and causes fever, chills, and flank pain.
What are nursing management/health promotion for a person with a UTI:
Recognize individuals at risk (women, elderly. pregnant women, immunosuppressed) Emptying bladder regularly and completely (Q 3-4 hours) Evacuating bowel regularly (constipation can cause UTI) Wiping perineal area front to back (E. Coli!) Drinking adequate fluids and cranberry juice (no apple juice) (person's weight in pounds/2) Avoid unnecessary catheterization and early removal of indwelling catheters (goal is remove in 24 hours) Aseptic technique - handwashing, gloving Perineal care for all hospitalized patients Heat therapy to supra pubic or lower back (low setting) *Patient may think drinking more fluids will necessitate needing help to go to the restroom. Fluids dilute urine, making bladder less irritable and also flushes out bacteria before they can colonize. Avoid incontinent episodes.
A urine culture should accompany what and what is it used for?
Sensitivity testing to dtermine the bacteria's susceptibility to a variety of antibiotic drugs. The results allow the HCP to select an antibiotic.
What are clinical manifestations of a UTI?
Signs of infection - fever, chills, malaise, cloudy and foul smelling urine, increased WBC, nausea and vomiting Urinary frequency (> Q 2 hours) and voiding small amounts, intermittency, weak stream, hesitancy, urgency, dysuria, inability to void, incomplete emptying of the bladder, post void dribbling, incontinence, nocturia, nocturnal enuresis, hematuria, pyuria Pain at the lower abdominal or back, burning micturition (CONTRACTION OF BLADDER), bladder spasms.

Symptoms often absent Nonlocalized abdominal discomfort rather than dysuria Cognitive impairment possible Fever less likely
Education on antibiotic therapy:
Take the entire course even if symptoms subside Take them at the same time every day to keep blood levels constant Can be harsh on stomach
Education for a female on a urine sample for a UA (A voided midstream technique; clean catch):
Teach them to spread the labia and wipe the periurethral area from front to back, using a moistened, clean gauze sponge (no antiseptic is used because it could contaminate the specimen and cause false-positive results). Then tell them to keep the labia spread and collect the specimen 1 to 2 seconds after voiding starts. *Refrigerate urine immediately on collection. *The urine should be cultured within 24 hours of refrigeration.
Nursing management evaluation of a UTI include:
The patient with a UTI will: Experience normal urinary elimination patterns Report relief of bothersome urinary tract symptoms Verbalize knowledge of treatment regimen
What antibiotics can be used long-term, prophylactic to prevent recurring UTIs?
Trimethoprim/sulfamethoxazole (Bactrim) Nitrofurantoin (Macrodantin) *A low dose of TMP/SMX, nitrofurantoin, or another antibiotic may be administered on a daily basis in an attempt to prevent recurring UTIs, or a single dose may be taken before an event likely to provoke a UTI, such as sexual intercourse. Although suppressive therapy is often effective on a short-term basis, this strategy is limited because of the risk of antibiotic resistance.
First-choice antibiotics used to treat uncomplicated UTIs include?
Trimethoprim/sulfamethoxazole (Bactrim) Nitrofurantoin (Macrodantin) Ampicillin, amoxicillin, cephalosporins
