Exam 3 Flashcards
Assessment with renal dysfunction
Labs: creatinine, BUN, CBC, Urinalysis
ask about urinary habits
hypertension, DM, and HF ???
History of UTI, kidney stones, family history
Urinalysis
purpose: evaluate waste product from kidney
measures: color, clarity, –concentration, specific gravity, pH, wbc, nitrate, bacteria, rbc, ketones, glucose
-collected early in morning
24 hour urine collection
purpose: measure creatinine clearance, urea nitrogen, sodium, chloride, calcium, and proteins
-discard the first void, then collect for next 24 hours
-collection restarted if any sample is discarded
-samples are refrigerated or on ice
renal ultrasound
purpose: noninvasive view of internal structures, can assess size of kidney
post- remove gel
renal CT/MRI
purpose: 3 dimensional imaging of organ system, can assess kidney size, cyst, or mass
prep:assess for iodine or shellfish allergy
post: assess kidney function
Voiding Cystourethrogram
purpose: detects urethral or bladder injury after instillation of contrast to provide imaging of bladder and ureters.
pre: informed consent, may require anesthesia
procedure: insert catheter, instill contrast, obtain x ray, remove catheter
post: monitor for UTI first 72 hours, increase fluids, monitor output
XRAY KUB
purpose: visualization of structure and detection of stones, strictures, calcium deposits, or obstructions
Pre-procedure: verify client is not pregnant, remove clothes over the area, remove all jewelry and metal objects
Kidney biopsy
Purpose: removal of a sample of tissue by excision or needle aspiration for
histological examination.
* Pre-procedure: informed consent, coagulation studies, NPO for at least 4
hours, typically local anesthesia, pt must lay prone (procedure is
contraindicated if they cannot lay in this position for extended periods)
* Post-procedure: monitor for bleeding–> high risk b/c kidney is highly
vascularized–> hematuria, H&H, bruising at puncture site
Cystoscopy/cystourethroscopy
Purpose: used to discover bladder wall abnormalities or occlusions of ureter or urethra
* Pre-procedure: NPO, informed consent, laxative or enema for bowel prep night before. May require anesthesia (not always)
* Intra-procedure: Lithotomy position, vitals monitoring
* Post-procedure: monitor urine output and characteristics (may be pink
tinged), irrigation may be necessary if blood clots are present, encourage
increased fluid intake
Lithotripsy
Purpose: to break a stone into smaller fragments
* Pre-procedure: pt must be able to lie flat, assess for dysrhythmia (as this
procedure can cause or worsen existing)
* Intra-procedure: monitor ECG
* Post-procedure: strain urine for stone passage, bruising may occur at site
(expected finding), assist with pain management r/t stone passage
Ureterolithotomy & nephrolithotomy
Percutaneous:
* Purpose: removal of stone through the skin.
* Pre-procedure: NPO, Informed consent, pt must lie prone
(contraindicated if they cannot do so for extended periods)
* Post-Procedure: monitor nephrostomy for drainage and presence of
blood
Open:
* Purpose: for large or impacted stones
* Pre-procedure: NPO, Bowel prep, Informed consent
* Post-procedure: monitor for excess bleeding, maintain fluid intake,
strain urine for passage of additional fragments, teach prevention
measures
Care and nursing interventions for a nephrostomy tube
Monitory amount of drainage and type hourly within the 1st 24 hours
* A decrease in drainage amount and back pain can indicate tube obstruction
or dislodgement
Monitor for nephrostomy leaking
Sterile dressing changes
Tube flushing–> to check patency and dislodge clots
Urinary tract infections
S/S: pain, fatigue, fever, confusion, frequency, urgency, dysuria, nocturia,
hematuria, retention, feeling of incomplete bladder emptying
* Diagnosis: history, physical exam, urinalysis, CBC, cystoscopy if
recurrent
* Tx: antibiotic therapy, phenazopyridine (urinary analgesic), antipyretic,
increased fluid intake, warm sitz bath 2-3 times a week can relieve pain
* Education: full abx course, drink 2-3 L/day, wipe front to back, do not
hold urine, phenazopyridine (urinary analgesic) will turn urine orange
* Labs: urinalysis–>expect positive WBCs, Nitrite, bacteria, leukocyte esterase, casts; Urine culture and sensitivity; CBC-> elevated WBCs
Renal calculi
S/S: flank pain, fluctuating pain (depending on location of stone), oliguria,
anuria, dysuria, hematuria, bladder distention.
* Diagnosis: x-ray KUB, CT KUB, Ultrasound KUB
* Tx: NSAIDs, Antiemetics, Antibiotics, increase fluid intake (to aid in
passing stone and prevent further stone formation), watchful waiting (for
stones to pass), straining of urine
* Education: once stone type has been determined, patient may need to alter
intake of certain foods.
* Calcium: avoid milk and other dairy products
* Oxalate: avoid spinach, black tea, and rhubarb
* Uric Acid: decrease purine intake–> poultry, fish, gravies, red
wines, sardines
* Struvite: typically results after a bacterial infection. Avoid high
phosphate foods (dairy, red or organ meats, whole grains)
* Labs: urinalysis–> rule out infections, may be positive for RBCs,
Hyperkalemia, Hyperphosphatemia
Polycystic Kidney Disease
S/S: weight gain (due to cyst formation and increased kidney size), flank pain, headache (stroke risk r/t hypertension), hematuria, hypertension (r/t decreased kidney perfusion and initiation of the RAAS system), dysuria, nocturia, constipation (enlarged kidney compresses bowels), enlarged abdominal girth (r/t enlargement of kidneys), kidney stones
* Diagnosis: ultrasound, family history/genetic testing
* Tx: blood pressure control (typically with ACEs or ARBs because they
work directly on the RAAS system), pain management (typically acetaminophen and nonpharmacologic interventions), interventions to slow progression of kidney damage (surgical cyst drainage, dialysis, smoking cessation), infection prevention, Pt will inevitably need a kidney transplant (if they live that long)
* Education: importance of diet (decrease sodium intake), importance of smoking cessation (hypertension risk),
* Labs: urinalysis: + proteinuria, + hematuria; decreased GFR; elevated BUN and creatinine levels, fluctuation in sodium level (can be wasted or retained)
Hydronephrosis/Hydroureter
S/S: flank pain, anuria, abdominal asymmetry (may indicate kidney mass),
abdominal tenderness
* Diagnosis: renal ultrasonography (1st choice), UA, CBC, CT or X-Ray
KUB
* Tx: removal or treatment of obstruction–>
nephrolithotomy/ureterolithotomy, cystoscopy, stent placement;
Nephrostomy placement
* Labs: depend on severity and related kidney damage–> if left untreated
kidney damage will result in low GFR, elevated BUN, elevated Creatinine
Pyelonephritis
S/S: UTI symptoms, N/V, recent cystitis or other UTI
* Diagnosis: urinalysis, culture and sensitivity, Imaging (X-ray KUB, CT)
* Tx: antibiotics, increase fluid intake, pain interventions, antipyretic,
* Education: do not hold urine, drink plenty of fluids, wipe front to back,
take full course of abx,
* Labs: BUN may be elevated (but creatinine will not), urinalysis- + WBC,
+ nitrite, + bacteria, cloudy, foul odor
Glomerulonephritis- acute and chronic
Acute: results from excess immune response within the kidney tissues –> onset about 10 days after time of infection
Chronic: do not know cause
S/S: Proteinuria, hematuria, hypertension, edema (especially in the face and hands), Pulmonary edema (dyspnea, shortness of breath, crackles), neck vein distension, weight gain
Diagnosis: can only be officially diagnosed by kidney biopsy
Tx: r/t fluid overload–> diuretics, sodium restriction, water restriction; Antihypertensives, Dialysis, antibiotic therapy
Education: educate on medication, if dialysis is required–> educate on vascular access care and dialysis schedule/routine
Labs: Elevated BUN and creatinine, electrolyte imbalances r/t ineffective filtration, urinalysis: + RBC and protein, decreased GFR (normal: greater than 125 mL/min)
Stages of bone healing
Hematoma formation within 24-72 hours of fracture
Granulation tissue invades hematoma to form fibrocartilage within 3 days-
2 weeks
Fracture site is surrounded by new vascular tissue known as a callus
within 3-6 weeks
Callus is gradually resorbed and transformed into bone within 3-8 weeks
Consolidation and remodeling of bone can continue for up to 1 year after
musculoskeltal assessment
Neurovascular assessment: Pain level/location/frequency, Sensation (presence of paresthesia), Skin temp/color, capillary refill, pulses (presence, strength, equality), movement (should have full ROM)
Musculoskeletal assessment: Range of motion, Gait, Spinal Alignment, Muscle size and symmetry, palpation for muscle tenderness, assessment of strength and equality, Performance of ADLs
PMH: previous traumatic injuries, previous or current illness (diabetes), family history (ex: osteoporosis)
Lifestyle: employment, social history
Open fracture
breaks through skin
closed fracture
break remains in skin
greenstick fracture
bends enough to snap but only cracks on one side
more common in children
sprial fracture
created from twisting motion; fracture line goes around
