RENAL: Brunner's Ch 55: Management of Patients with Urinary Disorders Flashcards
A female patient has been experiencing recurrent urinary tract infections. What health education should the nurse provide to this patient?
A) Bathe daily and keep the perineal region clean.
B) Avoid voiding immediately after sexual intercourse.
C) Drink liberal amounts of fluids.
D) Void at least every 6 to 8 hours.
C) Drink liberal amounts of fluids.
The patient is encouraged to drink liberal amounts of fluids (water is the best choice) to increase urine production and flow, which flushes the bacteria from the urinary tract. Frequent voiding (every 2 to 3 hours) is encouraged to empty the bladder completely because this can significantly lower urine bacterial counts, reduce urinary stasis, and prevent reinfection. The patient should be encouraged to shower rather than bathe.
A 42-year-old woman comes to the clinic complaining of occasional urinary incontinence when she sneezes. The clinic nurse should recognize what type of incontinence? A) Stress incontinence B) Reflex incontinence C) Overflow incontinence D) Functional incontinence
A) Stress incontinence
Stress incontinence is the involuntary loss of urine through an intact urethra as a result of sudden increase in intra-abdominal pressure. Reflex incontinence is loss of urine due to hyperreflexia or involuntary urethral relaxation in the absence of normal sensations usually associated with voiding. Overflow incontinence is an involuntary urine loss associated with overdistension of the bladder. Functional incontinence refers to those instances in which the function of the lower urinary tract is intact, but other factors (outside the urinary system) make it difficult or impossible for the patient to reach the toilet in time for voiding.
A nurse is caring for a female patient whose urinary retention has not responded to conservative treatment. When educating this patient about self-catheterization, the nurse should encourage what practice?
A) Assuming a supine position for self-catheterization
B) Using clean technique at home to catheterize
C) Inserting the catheter 1 to 2 inches into the urethra
D) Self-catheterizing every 2 hours at home
B) Using clean technique at home to catheterize
The patient may use a clean (nonsterile) technique at home, where the risk of cross-contamination is reduced. The average daytime clean intermittent catheterization schedule is every 4 to 6 hours and just before bedtime. The female patient assumes a Fowlers position and uses a mirror to help locate the urinary meatus. The nurse teaches her to catheterize herself by inserting a catheter 7.5 cm (3 inches) into the urethra, in a downward and backward direction.
A 52-year-old patient is scheduled to undergo ileal conduit surgery. When planning this patients discharge education, what is the most plausible nursing diagnosis that the nurse should address?
A) Impaired mobility related to limitations posed by the ileal conduit
B) Deficient knowledge related to care of the ileal conduit
C) Risk for deficient fluid volume related to urinary diversion
D) Risk for autonomic dysreflexia related to disruption of the sacral plexus
B) Deficient knowledge related to care of the ileal conduit
The patient will most likely require extensive teaching about the care and maintenance of a new urinary diversion. A diversion does not create a serious risk of fluid volume deficit. Mobility is unlikely to be impaired after the immediate postsurgical recovery. The sacral plexus is not threatened by the creation of a urinary diversion.
The nurse on a urology unit is working with a patient who has been diagnosed with oxalate renal calculi. When planning this patients health education, what nutritional guidelines should the nurse provide?
A) Restrict protein intake as ordered.
B) Increase intake of potassium-rich foods.
C) Follow a low-calcium diet.
D) Encourage intake of food containing oxalates.
A) Restrict protein intake as ordered.
Protein is restricted to 60 g/d, while sodium is restricted to 3 to 4 g/d. Low-calcium diets are generally not recommended except for true absorptive hypercalciuria. The patient should avoid intake of oxalate- containing foods and there is no need to increase potassium intake.
The nurse is caring for a patient who underwent percutaneous lithotripsy earlier in the day. What instruction should the nurse give the patient?
A) Limit oral fluid intake for 1 to 2 days.
B) Report the presence of fine, sand like particles through the nephrostomy tube.
C) Notify the physician about cloudy or foul-smelling urine.
D) Report any pink-tinged urine within 24 hours after the procedure.
C) Notify the physician about cloudy or foul-smelling urine.
The patient should report the presence of foul-smelling or cloudy urine since this is suggestive of a UTI. Unless contraindicated, the patient should be instructed to drink large quantities of fluid each day to flush the kidneys. Sand like debris is normal due to residual stone products. Hematuria is common after lithotripsy.
A female patients most recent urinalysis results are suggestive of bacteriuria. When assessing this patient, the nurses data analysis should be informed by what principle?
A) Most UTIs in female patients are caused by viruses and do not cause obvious symptoms.
B) A diagnosis of bacteriuria requires three consecutive positive results.
C) Urine contains varying levels of healthy bacterial flora.
D) Urine samples are frequently contaminated by bacteria normally present in the urethral area.
D) Urine samples are frequently contaminated by bacteria normally present in the urethral area.
Because urine samples (especially in women) are commonly contaminated by the bacteria normally present in the urethral area, a bacterial count exceeding 105 colonies/mL of clean-catch, midstream urine is the measure that distinguishes true bacteriuria from contamination. A diagnosis does not require three consecutive positive results and urine does not contain a normal flora in the absence of a UTI. Most UTIs have a bacterial etiology.
The clinic nurse is preparing a plan of care for a patient with a history of stress incontinence. What role will the nurse have in implementing a behavioral therapy approach?
A) Provide medication teaching related to pseudoephedrine sulfate.
B) Teach the patient to perform pelvic floor muscle exercises.
C) Prepare the patient for an anterior vaginal repair procedure.
D) Provide information on periurethral bulking.
B) Teach the patient to perform pelvic floor muscle exercises.
Pelvic floor muscle exercises (sometimes called Kegel exercises) represent the cornerstone of behavioral intervention for addressing symptoms of stress, urge, and mixed incontinence. None of the other listed interventions has a behavioral approach.
The nurse and urologist have both been unsuccessful in catheterizing a patient with a prostatic obstruction and a full bladder. What approach does the nurse anticipate the physician using to drain the patients bladder?
A) Insertion of a suprapubic catheter
B) Scheduling the patient immediately for a prostatectomy
C) Application of warm compresses to the perineum to assist with relaxation
D) Medication administration to relax the bladder muscles and reattempting catheterization in 6 hours
A) Insertion of a suprapubic catheter
When the patient cannot void, catheterization is used to prevent overdistention of the bladder. In the case of prostatic obstruction, attempts at catheterization by the urologist may not be successful, requiring insertion of a suprapubic catheter. A prostatectomy may be necessary, but would not be undertaken for the sole purpose of relieving a urethral obstruction. Delaying by applying compresses or administering medications could result in harm.
The nurse has implemented a bladder retraining program for an older adult patient. The nurse places the patient on a timed voiding schedule and performs an ultrasonic bladder scan after each void. The nurse notes that the patient typically has approximately 50 mL of urine remaining in her bladder after voiding. What would be the nurses best response to this finding?
A) Perform a straight catheterization on this patient.
B) Avoid further interventions at this time, as this is an acceptable finding.
C) Place an indwelling urinary catheter.
D) Press on the patients bladder in an attempt to encourage complete emptying.
B) Avoid further interventions at this time, as this is an acceptable finding.
In adults older than 60 years of age, 50 to 100 mL of residual urine may remain after each voiding because of the decreased contractility of the detrusor muscle. Consequently, further interventions are not likely warranted.
The nurse is caring for a patient recently diagnosed with renal calculi. The nurse should instruct the patient to increase fluid intake to a level where the patient produces at least how much urine each day? A) 1,250 mL B) 2,000 mL C) 2,750 mL D) 3,500 mL
B) 2,000 mL
Unless contraindicated by renal failure or hydronephrosis, patients with renal stones should drink at least eight 8-ounce glasses of water daily or have IV fluids prescribed to keep the urine dilute. A urine output exceeding 2 L a day is advisable.
A patient with cancer of the bladder has just returned to the unit from the PACU after surgery to create an ileal conduit. The nurse is monitoring the patients urine output hourly and notifies the physician when the hourly output is less than what? A) 30 mL B) 50 mL C) 100 mL D) 125 mL
A) 30 mL
A urine output below 30 mL/hr may indicate dehydration or an obstruction in the ileal conduit, with possible backflow or leakage from the ureteroileal anastomosis.
The nurse is caring for a patient with an indwelling urinary catheter. The nurse is aware that what nursing action helps prevent infection in a patient with an indwelling catheter?
A) Vigorously clean the meatus area daily.
B) Apply powder to the perineal area twice daily.
C) Empty the drainage bag at least every 8 hours.
D) Irrigate the catheter every 8 hours with normal saline.
C) Empty the drainage bag at least every 8 hours.
To reduce the risk of bacterial proliferation, the nurse should empty the collection bag at least every 8 hours through the drainage spout, and more frequently if there is a large volume of urine. Vigorous cleaning of the meatus while the catheter is in place is discouraged, because the cleaning action can move the catheter, increasing the risk of infection. The spout (or drainage port) of any urinary drainage bag can become contaminated when opened to drain the bag. Irrigation of the catheter opens the closed system, increasing the likelihood of infection.
The nurse is teaching a health class about UTIs to a group of older adults. What characteristic of UTIs should the nurse cite?
A) Men over age 65 are equally prone to UTIs as women, but are more often asymptomatic.
B) The prevalence of UTIs in men older than 50 years of age approaches that of women in the same age group.
C) Men of all ages are less prone to UTIs, but typically experience more severe symptoms.
D) The prevalence of UTIs in men cannot be reliably measured, as men generally do not report UTIs.
B) The prevalence of UTIs in men older than 50 years of age approaches that of women in the same age group.
The antibacterial activity of the prostatic secretions that protect men from bacterial colonization of the urethra and bladder decreases with aging. The prevalence of infection in men older than 50 years of age approaches that of women in the same age group. Men are not more likely to be asymptomatic and are not known to be reluctant to report UTIs.
A patient has been admitted to the postsurgical unit following the creation of an ileal conduit. What should the nurse measure to determine the size of the appliance needed? A) The circumference of the stoma B) The narrowest part of the stoma C) The widest part of the stoma D) Half the width of the stoma
C) The widest part of the stoma
The correct appliance size is determined by measuring the widest part of the stoma with a ruler. The permanent appliance should be no more than 1.6 mm (1/8 inch) larger than the diameter of the stoma and the same shape as the stoma to prevent contact of the skin with drainage.
A patient being treated in the hospital has been experiencing occasional urinary retention. What nursing action should the nurse take to encourage a patient who is having difficulty voiding?
A) Use a slipper bedpan.
B) Apply a cold compress to the perineum.
C) Have the patient lie in a supine position
D) Provide privacy for the patient.
D) Provide privacy for the patient.
Nursing measures to encourage normal voiding patterns include providing privacy, ensuring an environment and body position conducive to voiding, and assisting the patient with the use of the bathroom or bedside commode, rather than a bedpan, to provide a more natural setting for voiding. Most people find supine positioning not conducive to voiding.
