Chapter 16: Renal and Urinary Problems Flashcards
The nurse is reviewing the lab values for a patient with risk for urinary problems. Which finding is of most concern to the nurse?
- Blood urea nitrogen (BUN) of 10 mg/mL (3.6 mmol/L)
- Presence of glucose and protein in urine
- Serum creatinine of 0.6 mg/mL (53 mcmol/L)
- Urinary pH of 8
Ans: 2
When blood glucose levels are greater than 220 mg/dL (12.2 mmol/L), some glucose stays in the filtrate and is present in the urine. Normally, almost all glucose and most proteins are reabsorbed and are not present in the urine. Report the presence of glucose or proteins in the urine of a patient undergoing a screening examination to the health care provider because this is an abnormal finding and requires further assessment. Focus: Prioritization.
For which patient is the nurse most concerned about the risk for developing kidney disease?
- A 25-year-old patient who developed a urinary tract infection (UTI) during pregnancy
- A 55-year-old patient with a history of kidney stones
- A 63-year-old patient with type 2 diabetes
- A 79-year-old patient with stress urinary incontinence
Ans: 3
A history of chronic health problems, especially diabetes and hypertension, increases the risk for development of kidney disease. Focus: Prioritization.
The nurse is caring for a patient with risk for kidney disease for whom a urinalysis has been ordered. What time would the nurse instruct the unlicensed assistive personnel is best to collect this sample?
- With first morning void
- Before any meal
- At bedtime
- Immediately
Ans: 1
Urinalysis is a part of any complete physical examination and is especially useful for patients with suspected kidney or urologic disorders. Ideally, the urine specimen is collected at the morning’s first voiding. Specimens obtained at other times may be too dilute. Focus: Delegation, Supervision.
The nurse has delegated collection of a urinalysis specimen to an experienced unlicensed assistive personnel (UAP). For which action must the nurse intervene?
- The UAP provides the patient with a specimen cup.
- The UAP reminds the patient of the need for the specimen.
- The UAP assists the patient to the bathroom.
- The UAP allows the specimen to sit for more than 1 hour.
Ans: 4
Urine specimens become more alkaline when left standing unrefrigerated for more than 1 hour, when bacteria are present, or when a specimen is left uncovered. Alkaline urine increases cell breakdown; thus, the presence of red blood cells may be missed on analysis. Ensure that urine specimens are covered and delivered to the laboratory promptly or refrigerated. Actions 1, 2, and 3 are appropriate for urinalysis specimen collection. Focus: Delegation, Supervision.
The nurse is caring for a patient with risk for incomplete bladder emptying. Which noninvasive finding best supports this problem?
- Patient is able to void additional 100 mL after nurse massages over the bladder.
- Patient voids additional 350 mL with insertion of an intermittent catheter.
- Patient has postvoid residual of 275 mL documented by bedside bladder scanner.
- Patient has constant dribbling between voidings.
Ans: 3
The use of portable ultrasound scanners in the hospital and rehabilitation setting by nurses is a noninvasive method of estimating bladder volume. Bladder scanners are used to screen for postvoid residual volumes and to determine the need for intermittent catheterization based on the amount of urine in the bladder rather than the time between catheterizations. There is no discomfort with the scan, and no patient preparation beyond an explanation of what to expect is required. Use of bladder massage or presence of urinary dribbling is inexact, and intermittent catheterization is invasive. Focus: Prioritization.
The nurse is providing care for a patient after a kidney biopsy. Which actions should the nurse delegate to an experienced unlicensed assistive personnel (UAP)? Select all that apply.
- Check vital signs every 4 hours for 24 hours.
- Remind the patient about strict bed rest for 2 to 6 hours.
- Reposition the patient by log-rolling with supporting backroll.
- Measure and record urine output.
- Assess the dressing site for bleeding and check complete blood count results.
- Teach the patient to resume normal activities after 24 hours if there is no bleeding.
Ans: 1, 2, 3, 4
Checking vital signs, repositioning patients, and recording intake and output are within the scope of practice for a UAP. Assessing and teaching are more within the scope of practice for professional nurses. If no bleeding occurs, the patient can resume general activities after 24 hours. However, instruct him or her to avoid lifting heavy objects, exercising, and performing other strenuous activities for 1 to 2 weeks after the biopsy procedure. Driving may also be restricted. Focus: Delegation, Supervision.
The nurse is providing nursing care for a 24-year-old female patient admitted to the acute care unit with a diagnosis of cystitis. Which intervention should the nurse delegate to the unlicensed assistive personnel (UAP)?
- Teaching the patient how to secure a clean-catch urine sample
- Assessing the patient’s urine for color, odor, and sediment
- Reviewing the nursing care plan and add nursing interventions
- Providing the patient with a clean-catch urine sample container
Ans: 4
Providing the equipment that the patient needs to collect the urine sample is within the scope of practice of a UAP. Teaching, planning, and assessing all require additional education and skill, which is appropriate to the scope of practice of professional nurses. Focus: Delegation, Supervision.
Which laboratory result is of most concern to the nurse for an adult patient with cystitis?
- Serum white blood cell (WBC) count of 9000/mm3 (9 x 109/L)
- Urinalysis results showing 1 or 2 WBCs present
- Urine bacteria count of 100,000 colonies per milliliter
- Serum hematocrit of 36%
Ans: 3
The presence of 100,000 bacterial colonies per milliliter of urine or the presence of many white blood cells (WBCs) and red blood cells (RBCs) indicates a urinary tract infection. This WBC count is within normal limits, and the hematocrit is a little low, which may need follow-up. Neither of these results indicates infection. Focus: Prioritization; Test Taking Tip: It is essential that the nurse be alert to any signs or symptoms of infection for a patient. In this case, the presence of so many bacterial colonies indicate the presence of an infection in the bladder, which needs to be treated with antibiotics.
The charge nurse would assign the nursing care of which patient to an LPN/LVN, working under the supervision of an RN?
- A 48-year-old patient with cystitis who is taking oral antibiotics
- A 64-year-old patient with kidney stones who has a new order for lithotripsy
- A 72-year-old patient with urinary incontinence who needs bladder training
- A 52-year-old patient with pyelonephritis who has severe acute flank pain
Ans: 1
The patient with cystitis who is taking oral antibiotics is in stable condition with predictable outcomes, and caring for this patient is therefore appropriate to the scope of practice of an LPN/LVN under the supervision of an RN. The patient with a new order for lithotripsy will need teaching about the procedure, which should be accomplished by the RN. The patient in need of bladder training will need the RN to plan this intervention. The patient with flank pain needs careful and skilled assessment by the RN. Focus: Assignment.
The nurse is admitting a 66-year-old male patient suspected of having a urinary tract infection (UTI). Which part of the patient’s medical history supports this diagnosis?
- Patient’s wife had a UTI 1 month ago
- Followed for prostate disease for 2 years
- Intermittent catheterization 6 months ago
- Kidney stone removal 1 year ago
Ans: 2
Prostate disease increases the risk of UTIs in men because of urinary retention. The wife’s UTI should not affect the patient. The times of the catheter usage and kidney stone removal are too distant to cause this UTI. Focus: Prioritization.
A patient is being admitted to rule out interstitial cystitis. What should the nurse’s plan of care for this patient include specific to this diagnosis?
- Take daily urine samples for urinalysis.
- Maintain accurate intake and output records.
- Obtain an admission urine sample to determine electrolyte levels.
- Teach the patient about the cystoscopy procedure.
Ans: 4
A cystoscopy is needed to accurately diagnose interstitial cystitis. Urinalysis may show white blood cells and red blood cells but no bacteria. The patient will probably need a urinalysis upon admission, but daily samples do not need to be obtained. Intake and output may be assessed, but results will not contribute to the diagnosis. Cystitis does not usually affect urine electrolyte levels. Focus: Prioritization.
The RN is supervising a new graduate nurse who is orientating to the unit. The new nurse asks why the patient with uncomplicated cystitis is being discharged with a prescription for ciprofloxacin 250 mg twice a day for only 3 days. What is the RN’s best response?
- “We should check with the health care provider because the patient should take this drug for 10 to 14 days.”
- “A 3-day course of ciprofloxacin is not the appropriate treatment for a patient with uncomplicated cystitis.”
- “Research has shown that a 3-day course of ciprofloxacin is effective for uncomplicated cystitis and there is increased patient adherence to the plan of care.”
- “Longer courses of antibiotic therapy are required for hospitalized patients to prevent nosocomial infections.”
Ans: 3
For uncomplicated cystitis, a 3-day course of antibiotics is an effective treatment, and research has shown that patients are more likely to adhere to shorter antibiotic courses. Seven-day courses of antibiotics are appropriate for complicated cystitis, and 10- to 14-day courses are prescribed for uncomplicated pyelonephritis. This patient is being discharged and should not be at risk for a nosocomial infection. Focus: Prioritization, Supervision.
A 28-year-old married female patient with cystitis requires instruction about how to prevent future urinary tract infections (UTIs). The supervising RN has assigned this teaching to a newly graduated nurse. Which statement by the new graduate requires that the supervising RN intervene?
- “You should always drink 2 to 3 L of fluid every day.”
- “Empty your bladder regularly even if you do not feel the urge to urinate.”
- “Drinking cranberry juice daily will decrease the number of bacteria in your bladder.”
- “It’s okay to soak in the tub with bubble bath because it will keep you clean.”
Ans: 4
Women should avoid irritating substances such as bubble baths, nylon underwear, and scented toilet tissue to prevent UTIs. Adequate fluid intake, consumption of cranberry juice, and regular voiding are all good strategies for preventing UTIs. Focus: Assignment, Supervision, Prioritization.
The nurse is creating a care plan for older adult patients with incontinence. For which patient will a bladder-training program be an appropriate intervention?
- Patient with functional incontinence caused by mental status changes
- Patient with stress incontinence due to weakened bladder neck support
- Patient with urge incontinence and abnormal detrusor muscle contractions
- Patient with transient incontinence related to loss of cognitive function
Ans: 3
A patient with urge incontinence can be taught to control the bladder as long as the patient is alert, aware, and able to resist the urge to urinate by starting a schedule for voiding, then increasing the intervals between voids. Patients with functional incontinence related to mental status changes or loss of cognitive function are not able to follow a bladder-training program. A better treatment for a patient with stress incontinence is exercises such as pelvic floor (Kegel) exercises to strengthen the pelvic floor muscles. Focus: Prioritization.
A patient with incontinence will be taking oxybutynin chloride 5 mg by mouth three times a day after discharge. Which information would a nurse be sure to teach this patient before discharge?
- “Drink fluids or use hard candy when you experience a dry mouth.”
- “Be sure to notify your health care provider (HCP) if you experience a dry mouth.”
- “If necessary, your HCP can increase your dose up to 40 mg/day.”
- “You should take this medication with meals to avoid stomach ulcers.”
Ans: 1
Oxybutynin is an anticholinergic agent, and these drugs often cause an extremely dry mouth. The maximum dosage is 20 mg/day. Oxybutynin should be taken between meals because food interferes with absorption of the drug. Focus: Prioritization.
