Question | Answer |
---|---|
Proteinuria | presence of large proteins in urine which is a sing of glomerular injury. |
Erythropoietin | hormone that functions within bone marrow to stimulate red blood cell production and maturation and prolongs life of mature Red Blood Cells. |
Renin | an enzyme released from juxtaglomerular cells which convert angiotensin I. |
Micturation | voiding |
Renal Calculus | kidney stones |
Uremic syndrome | an increase in nitrogenous wastes in blood, marked fluid and electrolyte abnormalities, nausea, vomiting headache, coma and convulsions |
Renal replacement therapies | dialysis and organ replacement |
Nocturia | awakening to void one or more times a night. |
Polyuria | excessive output of urine |
Oliguria | urine output decreased despite normal intake of fluid |
Anuria | no urine |
Diuresis | increased urine formation |
Urinary diversion | surgical formation which temporarily or permanently bypasses urethra as exit routes for urine |
Urinary tract infection | are infections that can happen anywhere along the urinary tract |
Dysuria | pain or burning during urination |
Cystisis | irritated bladder |
Hematuria | irritation to bladder and urethral mucosa results in blood tinged urine |
Pylonephritis | infection of upper urinary tract where flank pain, tenderness, fever and chills are common symptoms. |
Urinary incontinence UI | is the involuntary leakage of urine that is sufficient to be a problem. It is either temporary or permanent |
Nephrostomy | urinary drainage directly from one or both kidneys in which tube is place directly into renal pelvis. |
Bacteriuria | bacteria in urine |
Bacteremia or urosepsis | bacteria in blood stream |
Urinary frequency | bladder loses muscle tone and capacity decreases which leads to voiding more often |
Nocturnal enuresis | nighttime voiding without awakening |
Residual urine | retained urine after voiding |
meatus | opening of urethra |
urinalysis | a lab test on a urine specimen |
specific gravity | is weight or degree of substance compared with equal volume of water |
catheterization | of bladder involves introducing latex or plastic tube through urethra into bladder. Catheter provides continuous flow of urine in clients unable to control micturation or has other obstructions. |
pelvic floor exercises | also know as Kegel's, improve strength of pelvic floor muscles and consist of repetitive contractions of muscle groups. |
Normal physiology of urinary elimination | Kidneys lie on either side of the vertebral column behind peritoneum and against deep muscles in back. |
Filter of metabolic wastes | Blood reaches each kidney by renal artery. The nephron, fuctional unit of kidneys, forms urine. A cluster of blood vessels form capillaries of glomerulus, which is initial site of urine formation. Glomerular capallaries filtrate into Bowman's capsule. |
Nephron | composed of glomerulus, Bowmand's capsule, proximal convoluted tubule, loop of Henle, distal tubule and collecting duct. |
Glomerular capallaries | permit filtration of water, glucose, urea, creatinine and major electrolytes into Bowman's capsule. |
Regulate fluid level | kidneys play a role in fluid and elecrolyte balance. 99% of filtrate is reabsored in plasma with 1% excreted as urine. Less than 30 ml/hr indicates renal alterations. |
regulate composition of electrolytes | maintains salt and potassium levels in body |
assist in acid/base balance | kidneys excretes excess acids or bases |
regulates blood pressure | regulates by renin which converts angiotenigin to angiotensin I which is converted to AII in lungs and this causes vasoconstriction and stimulates release of aldosterone from renal cortex and this causes retention of water which increases blood volume. |
Regulates RBCs through erythropoietin | whcih functions in marrow to produce RBCs and older RBCs get prolonged life. |
Aids in calcium metabolism | It activates Vitamin D. Kidneys produces a substance to turn Vitamin D into active form body can use. |
Urinary tract/Bladder | urinary bladder is hollow distensible, muscular organ that stores and excretes urine. Empty lies flat in pelvic cavity behind symphysis pubis. Bladder expands as it fills. When full can expand above symphysis pubis. |
Urinary tract/Ureters | are tubular structures that enter the bladder. Urine draining to bladder is sterile. Peristaltic waves cause urine to enter body in spurts not steadily |
Urinary tract/ Urethra | urine travels from bladder through urethra and passes outside body through urethral meatus. Women are 4 to 6.5 cm long and men are 20 cm or 8 inches |
Autonomic Nervous System | Functions of the urinary bladder depend entirely on the autonomic nervous system. |
Micturation | several brain structures influence bladder function, cerebral cortex, thalamus, hypothalamus, and brain stem. All these allow voiding or halt it. |
Voiding | Bladder normally holds 600 ml of urine. Individuals feel desire to void with smaller amount of 150 to 200 ml for an adult and 50 to 100 ml for child. as bladder walls stretch, sending sensory impulses to micturation center of spinal chord. |
Factors affecting urinary elimination/assessment/Disease conditions | decreases blood flow to and through the kidney (prerenal) disease condition of renal tissue or obstruction in lower urinary tracts that prevents urine flow from kidneys sometimes alter renal function. |
Assessment/Disease conditions Diabetes Melitis and Multiple sclerosis. | causes changes in nerve functions that can lead to possible loss of bladder tone, reduced sensation or inabilty to stop contractions. |
Uremic syndrome | people with end stage renal disease leads to build up of toxins, nitrogenous wastes in blood. Eventually needing renal replacement therapies. |
Assessment/ Growth and development | infants and young children cannot effectively control urinating. 2 to 3 yrs. know sensations for bladder filing and urination. Many 4 yr olds can have control of external sphincter, which starts potty training. |
Assessment/ Growth and development | Pregnancy- urinary frequency and UTIs are common, decreased muscle tone. Aging causes impaired micturation and decreased muscle tone. |
Assessment/ Growth and development | Men beginning at 40 get enlarged prostates which cut off urine flow. Women have changes in urethral mucosa increases risk of UTIs. |
Assessment/ Sociocultural Factors | It has to do with amount of privacy for each culture. Americans expect privacy and Europeans have communal toilet facilities. |
Assessment/ Psychological Factors | anxiety prevents being able to void completely, Emotional tension makes it difficult to relax perineal and abdominal muscles. |
Assessment/ Fluid Balance | kidneys maintain balance of retention and excretion of fluids. an increase in intake of fluids leads to increase of urine production. Coffee, tea and cola increase urine production. Alcohol causes a water loss in urine. |
Assessment/ Muscle Tone | can affect elimination through urinary retention, it makes bladder unable to respond to micturation reflex. |
Muscle Tone/ urinary incontinence | a involuntary leakage due to weak mucles. weak abdominal muscles and pelvic floor muscles impair ability of urinary sphincter to maintain tone during increased abdominal pressure. |
Surgical procedures/ narcotic analgesics and anesthetics | slow glomerular filtration, reducing urine output. |
Surgical procedures/Spinal anesthetics | causes urinary retention. |
Surgical procedures/ Surgery-lower abdomen | causes impaired urination from trauma to local tissue. |
Medications/ Diuretics | prevent water reabsortion and certain electrolytes by increasing urine output. |
Medications/ Anticholinergics and Antihistamines | cause urinary retention |
Medications/ Phenzopyriedine(Pyridium) | turns urine orange |
Medications/ amitryptyline | turns urine green or blue |
Medications/Levodopa | turns urine black or brown. |
Diagnostic Exam/ Intravenous pylogram (IVP) | requires limitations on liquids which lower urine output. |
Diagnostic Exam/ Direct visualization diagnostic exams | cause localized edema of urethral passageways and spasms of bladder sphincter. |
Alterations/urinary retention | is an accumulation of urine resulting from inability of bladder to empty properly. Bladder is unable to control micturation and empty bladder. Urine collects stretching walls causing discomfort, tenderness and diaphoresis. |
Alterations/ Lower urinary tract infections | have pain, burning during urination as flows over inflamed tissues. Causes are because in women have shorter urethra and proximity to anus. Older adults, disease or decreased immunity. Poor perineal hygiene. Inadequate hand washing and catheters. |
Alterations/Urinary Incontinence | is involuntary leakage of urine. 2 kinds stress or urge. older adults have special problems because of physical limitation and environmental barriers. |
Alterations/ Urinary diversions | urinary stoma to divert the flow of urine directly to abdominal wall because of cancer, trauma, etc. |
Nursing History/pattern of urination | ask client about daily voiding patterns, including frequency,times of day, normal volume and any recent changes. |
Nursing History/ symptoms of urinary alterations | assess for urgency, dysuria, hesitancy, frequency, polyuria, oliguria, nocturia, incontinence, hematuria, retention or residual urine. |
Factors | age, environmental, medication history, fluid balance, current surgical or diagnostic disease conditions. Bowel patterns, fluid balance or urinary diversions. |
assessment/ input and output | fluid balance with intake and output measurements |
assessment/ characteristics/ color | normal pale yellow to clear red- bleeding bright orange-pyridium dark amber-bilirubin-liver dysfunction document unusual color or sediment |
assessment/ clarity | stagnant-ammonia-incontinent sweat odor-acetone-diabetic/starvation |
Urine testing/Urinalysis/UA | try to make it the first void of morning to ensure uniform concentration of contituents. Normal values:ph-4.6 to 8.0, protein, glucose, ketones, blood-negative is normal, and specific gravity 1.0053-1.030 |
Urine testing/ CMP/ comprehensive Metabolic Panel | blood test that tells current status of kidneys, liver and electrolytes and acid/base balance as well as blood sugar and proteins. |
Diagnostic Studies/ KUB? Abdominal roentergenogram | X-ray to determin the size shape, symmetry and location of urinary system |
Diagnostic Studies/ IVP Intravenous pyelogram | veiw collecting ducts and renal pelvis and outline ureters, bladder and urethra. a special intravenous injection converts to dye in urine. Assess for allergies to shellfish and plenty of liquids after to flush dye. |
Diagnostic Studies/Renal Scan/CT scan | obtains detailed images of structures in body/ Cross sectional which shows tumors and obstructions. Bowel cleansing and shellfish allergies before and liquids afterward. |
Diagnostic Studies/Endoscopy | goes right into urinary system for an inside view of kidneys, bladder etc. |
Diagnostic Studies/Arteriogram | an x-ray of arterioles to evaluate their condition. |
Diagnostic Studies/ Urodynamics | determine bladder function and evaluate causes of urinary incontinence |
promoting urinary elimination/stimulating reflex | a client's ability to void depends on felling the urge to urinate, being able to control the urethral sphincter and relax during voiding. To relax and stimulate reflex a client needs to be put in normal position. women/sitting;man/standing. |
promoting urinary eliminations/maintaining habits | clients need to follow normal schedule |
promoting urinary elimination/adequate fluid intake | average daily intake is 1200 to 1500 mls. Increase fluids clears you out. |
promoting urinary elimination/ promote complete bladder emptying | always residual urine left in bladder encourage clients to wait until urine stops and attempt to void again |
promoting urinary elimination/prevent infection | good perineal hygiene Fluids(2000 to 2500 ml) |
Catheterization | involves a latex or plastic tube through the urethra and into bladder. The catheter provide a continuous flow of urine when client's cannot control voiding or those with obstructions. |
What is the function of the kidneys? | Kidneys filter waste products of metabolism that collect in the blood. The blood reaches each kidney by a renal (kidney) artery that branches from the abdominal aorta. |
Kidneys filter waste products of metabolism that collect in the blood. The blood reaches each kidney by a renal (kidney) artery that branches from the abdominal aorta. | The kidneys produce several substances vital to production of red blood cells (RBCs), blood pressure, and bone mineralization. The kidneys are responsible for maintaining a normal RBC volume by producing erythropoietin. |
