Final Flashcards
Know the preferred way to monitor the fluid volume status REF: 898-899
Daily weights are an important indicator of fluid status (Metheny, 2010). Each kilogram (2.2 lbs) of weight gained or lost overnight is equal to 1 L of fluid retained or lost. These fluid gains or losses indicate changes in the amount of total body fluid, usually ECF, but do not indicate shift between body compartments. Weigh the patient at the same time each day with the same scale after a patient voids.
Measuring and recording all liquid intake and output (I&O) during a 24-hour period is an important aspect of fluid balance assessment. Compare a patient’s 24-hour intake with his or her 24-hour output. The two measures should be approximately equal if the person has normal fluid balance.
Intake - liquids in food, drinks, IV fluids, blood components
Output - urine, diarrhea, vomitus, gastric suction, and drainage from postsurgical wounds or other tubes. Record a patient’s urinary output after each voiding. (Potter 898)
Know which fluid therapy is given initially REF: 905
Best guess - IV therapy for normal saline .9% - isotonic, won’t cause dangerous shifts in volumes between ECF, ICF, fastest route, only fluid compatible with blood
Know the symptoms of Fluid volume overload REF: 909-913
Extracellular Fluid Volume Excess—Body Fluids Have Increased Volume but Normal Tonicity
Sodium and water intake greater than output, causing isotonic gain:
Excessive administration of sodium-containing isotonic parenteral fluids
Excessive oral intake of salty foods and water
Decreased renal output caused by elevated aldosterone: Chronic heart failure, cirrhosis, aldosterone-secreting tumor
Decreased renal output from other causes: Oliguric acute kidney disease, end-stage chronic renal disease, glucocorticoid excess
Physical examination: Sudden weight gain (e.g., overnight), edema (especially in dependent areas), neck veins full when upright or semi-upright, crackles in dependent portion of lungs, pulmonary edema
Laboratory findings: Decreased hematocrit; BUN less than 10 mg/dL (3.6 mmol/L) caused by hemodilution (Potter 889)
Know the symptoms of Fluid volume overload REF: 909-913
Signs of ECV excess
Gain of 2.2 lbs (1 kg) or more in 24 hours for adults
Pulse rate and character: Bounding
Fullness of neck veins: Full or distended when upright or semi-upright
Lung auscultation, dependent portions: Crackles or rhonchi with progressive dyspnea
Presence of edema: Present in dependent areas (ankles or sacrum) and possibly fingers or around eyes (Potter 899)
Know the symptoms of Fluid volume overload REF: 909-913
Circulatory overload of IV solution
Depends on type of solution
ECV excess with Na+ containing isotonic fluid (crackles in dependent portions of lungs, shortness of breath, dependent edema)
Hyponatremia with hypotonic fluid (confusion, seizures)
Hypernatremia with Na+ containing hypertonic fluid (confusion, seizures)
Hyperkalemia from K+ containing fluid (cardiac dysrhythmias, muscle weakness, abdominal distention)
If symptoms appear, reduce IV flow rate and notify patient’s health care provider.
With ECV excess raise head of bed; administer oxygen and diuretics if ordered.
Monitor vital signs and laboratory reports of serum levels.
Health care provider may adjust additives in IV solution or type of IV fluid; watch for and implement order. (Potter 910)
Differentiate between oliguria anuria and polyuria REF: 1045
An excessive output of urine is polyuria. A urine output that is decreased despite normal intake is called oliguria. Oliguria often occurs when fluid loss through other means (e.g., perspiration, diarrhea, or vomiting) increases. It also occurs in early kidney disease. Often in severe kidney disease no urine is produced (anuria). (Potter 1045)
Identify factors that commonly influence urinary elimination REF: 1045
Most patients with urinary problems are unable to store urine or fully empty the bladder. These disturbances result from impaired bladder function, obstruction to urine outflow, or inability to voluntarily control micturition.
Some patients may have permanent or temporary changes in the normal pathway of urinary excretion. The surgical formation of a urinary diversion temporarily or permanently bypasses the bladder and urethra as the exit routes for urine. The patient with a urinary diversion has a stoma (artificial opening) on the abdomen to drain urine.
Retention occurs as a result of urethral obstruction, surgical or childbirth trauma, and alterations in motor and sensory innervation of the bladder such as occurs with neuropathy secondary to diabetes. It may occur after removal of an indwelling catheter. Medication side effects or anxiety may also result in urinary retention. If a patient cannot void or completely empty the bladder, he or she must be catheterized because a UTI, kidney stones, and hyperreflexia can occur.
Retained or residual urine, also referred to as postvoid residual (PVR), occurs if a patient has urinary retention or cannot empty the bladder completely. Spastic bladders and some medications and problems such as using a bedpan or not sitting upright to void cause inconsistent emptying. (Potter 1046)
Know common causes of urinary tract infections (UTI) REF: 1046-1047
80% of these infections result from the use of an indwelling urethral catheter
Women are more susceptible to infection because of a short urethra and the proximity of the anus to the urethral meatus. In men prostatic secretions containing an antibacterial substance and the length of the urethra reduce the susceptibility to UTIs.
However, men are at increased risk for infection-related renal disease. Older adults and patients with progressive underlying disease or decreased immunity are also at increased risk.
Any condition resulting in urinary retention such as a kinked, obstructed, or clamped catheter increases the risk of a UTI.
Poor perineal hygiene is another cause of UTIs in women. Inadequate handwashing, failure to wipe from front to back after voiding or defecating, and frequent sexual intercourse predispose women to infection.
Another common cause of infection is the introduction of instruments into the urinary tract. For example, the introduction of a catheter through the urethra provides a direct route for microorganisms (Potter 1046-1047)
Know nursing diagnoses appropriate for patients with alterations in urinary elimination REF: 1047 (What are the two types?)
Invasive and non invasive
Name the types of Urinary diagnosis that are non-invasive
Abdominal roentgenogram Computerized axial tomography (CT) scan Intravenous pyelogram (IVP) Ultrasound Urodynamic testing (uroflowmetry)
Name the types of Urinary diagnosis that are invasive
Endoscopy-cystoscopy
Surgery on the male prostate is also performed using a special endoscope.
Arteriogram (angiography)
Visualize the renal arteries and/or their branches to detect narrowing or occlusion. A catheter is placed in one of the femoral arteries and introduced up to the level of the renal arteries. Radiopaque contrast is injected through the catheter while x-ray film images are taken in rapid succession.
(Question: What type of diagnosis is this, invasive or non invasive and how is this diagnosis done?).
Arteriogram (angiography)
Provide direct visualization, specimen collection, and/or treatment of the interior of the bladder and urethra.
Although this procedure is usually performed using local anesthesia, general anesthesia or conscious sedation is more common to avoid unnecessary anxiety and trauma for the patient
(Question: What type of diagnosis is this, invasive or non invasive and how is this diagnosis done?).
Endoscopy-cystoscopy
What diagnosis tool is used to perform surgery on the prostate?
Endoscopy
What is the checklist after a prostate surgery?
After patient’s return assess the vital signs and the characteristics of urine; monitor intake and output (I&O); encourage fluids; and observe for fever, dysuria, and pain in suprapubic region for bladder distension (expansion)
What is the checklist after an Arteriogram (angiography)?
After the procedure monitor vital signs frequently until stable. Patient maintains bed rest for prescribed time interval. Encourage fluids to flush the contrast from the system. Also monitor the affected extremity for neurocirculatory function (pulse, skin temperature, sensation, and movement) and observe catheter site for bleeding, swelling, increased tenderness, or hematoma formation.
Notify health care provider immediately of any postprocedure abnormality
What are the nursing interventions for urinary retention?
Patient education Promoting Normal Micturition Maintaining Elimination Habits Medications Catheterization
How do you educate patient on urinary retention?
First focus the teaching on their specific elimination problems. For example, patients who practice poor hygiene benefit most from learning about normal sterility of the urinary tract and how frequent handwashing and proper perineal hygiene reduce the risks for infection. Patients also learn the significance of symptoms of urinary alterations so they can initiate early preventive health care. (Potter 1059)
How do you promote normal micturition?
1) Stimulate Micturition Reflex
2) Maintain elimination habits
3) Maintain adequate fluid levels
4) Promote complete bladder emptying
5) Preventing infection
What do the following exercises help to do?
Help patients learn to relax and stimulate the reflex to void by helping them assume the normal position for voiding. A woman voids better - squatting / sitting. A man voids better - standing. Sensory stimuli. The sound of running water. Stroking the inner aspect of the thigh promotes the micturition reflex. You can also pour warm water over the patient’s perineum and create the sensation to urinate. If you need to measure urine output, first measure the volume of water that you pour over the perineal area.
Stimulating Micturition Reflex -
What are the three things the patient depends on in or to have the ability to void (micturition)
1) A patient’s ability to void depends on feeling the urge to urinate,
2) being able to control the urethral sphincter,
3) being able to relax during voiding.
How do you maintain elimination habits?
patients follow routines to promote normal voiding. Integrating patients’ habits into the care plan fosters normal voiding
In regards to the urinary system, why is maintaining adequate fluid intake important? How much should you intake?
helps flush out solutes or particles that collect in the urinary system
normal renal function no heart or kidney disease - drink 2200 to 2700 mL of fluid daily
a minimal daily intake of 1200 to 1500 mL of fluids ok unless the patient has a history of UTI
encourage fluids that the patient prefers, veggies/fruits. At home it helps to set a schedule for drinking fluids (e.g., with meals or medications). To minimize nocturia, avoid fluids 2 hours before bedtime.
How do you Promote Complete Bladder Emptying?
Encouraging patients to wait until urine stops flowing or to attempt to void again (double voiding) can improve bladder emptying (Table 45-5). Urinary retention care includes scheduled toileting (Lewis et al., 2011). In addition, Credé’s method or manual compression of the bladder walls with each attempted void may be used (Madineh, 2008). Instruct the patient to place both hands flat on the abdomen below the umbilicus and above the symphysis pubis with the fingers pointed down toward the bladder dome. Have him or her compress the hands downward against the walls of the bladder while tightening the perineum, contracting the abdominal wall, and holding the breath. The maneuver promotes bladder emptying by relaxing the urethral sphincter. (Potter 1060)
How do you prevent infection of the bladder?
Good perineal hygiene that includes cleaning the urethral meatus after each voiding or bowel movement is essential. A minimal daily fluid intake of 1200 to 1500 mL flushes the urethra of microorganisms. Voiding after intercourse; not using excessive soap or taking bubble baths; wearing cotton underwear; and drinking enough fluids, especially fluids high in acid ash such as apple or cranberry juice help prevent UTI.
What are the things to take into consideration when maintaining elimination habits?
Patients usually require time to void. 30 minutes to provide a specimen. Patients normally void on awakening or before meals. Also important is the need to respond to and anticipate patients’ urges to urinate. Older-adult falls are related to the urge to urinate. Anticipate the need and provide for scheduled bathroom visits to help reduce the fall risk in these patients. Need privacy for voiding. Young children are often unable to void in the presence of persons other than their parents. Special measures - some patients are able to relax and void more easily while reading or listening to music. Having a cup or glass of fluids also promotes urination.
