Renal Flashcards
AKI, CKD, acute glomerulonephritis, hemodialysis, peritoneal dialysis, UTI
Acute glomerulonephritis patho
Occurs after exposure to strep infx
SLE
S+S of acute glomerulonephritis
Oliguria
Dark, rust-colored urine
Hematuria, proteinuria
Edema
HTN
Weight gain
Anorexia, malaise, weakness
UA and lab studies of acute glomerulonephritis
UA: RBCs, protein
Elevated: BUN, creatinine, evidence of recent strep infx
Positive throat culture
Tx of acute glomerulonephritis
Supportive care
Antihypertensive agents, diuretics, temporary dialysis, abx
Sodium-restricted diet
Report HA to HCP
Seizure precautions
CKD causes
DM and HTN
S+S of CKD
Volume overload: edema, pleural effusions, HTN
Accumulation of urea and waste products: pruritis, lethargy, sleep changes, peripheral neuropathy
Low EPO -> anemia
Vitamin D and metabolism -> bone dz
Lab values of CKD
High potassium, phosphorous
Low calcium, GFR
Metabolic acidosis
Pharm of CKD
HTN: ACE inhibitors, ARBs
Anemia: EPO injections, iron
Edema: diuretics
Protect bones: calcium and vitamin D
Hyperkalemia: oral intestinal K binders (sodium zirconium, patiromer)
Hyperphosphatemia: oral phosphate binders (calcium acetate/carbonate)
Metabolic acidosis: sodium bicarbonate
Diet of CKD
Low potassium
Low phosphorous
Sodium and fluid restriction
Modest protein restriction
Hemodialysis dialysis solution
Electrolytes and dextrose can be added
Procedure of hemodialysis
Access pt’s circulation
Administer heparin to pt
Heparinized blood flows through semipermeable membrane in one direction
Dialysis solution flows in opposite direction
Wastes are removed and electrolytes are corrected via diffusion
Ultrafiltration removes excess water from blood
Blood returns to pt via the access line after it has been cleansed
Interventions of hemodialysis
Administer anticoagulants (heparin)
Withhold antihypertensives prior to hemodialysis
Obtain BP on arm opposite of fistula/graft
Provide appropriate nutrition
Weigh before and after
If air embolism occurs during hemodialysis, what tx
Clamp access tubing
Reposition to Trendelenburg on left side
Administer oxygen (high-flow)
Notify HCP
Disequilibrium syndrome def and S+S
Solutes are removed from blood faster than CSF and brain
N+V, restlessness, agitation, confusion -> seizures -> death
Disequilibrium syndrome during hemodialysis tx
Slow/stop dialysis
Notify HCP
Reduce environmental stimuli
Prepare to administer IV hypertonic saline and mannitol
Prepare to dialyze for shorter periods at reduced flow rates to prevent recurrence
When accessing dialysis cath (peritoneal dialysis), what precautions are there to follow?
Wear a mask
Use aseptic technique
Cleanse around insertion site
Troubleshooting peritoneal dialysis
Keep drainage bag below abdomen
Check for kinks in tubing
Change the position by turning the pt to a side-lying position or by asking the pt to walk
Assess for constipation and provide options for relief such as stool softener
Peritonitis S+S during peritoneal dialysis
Tachycardia
Fever
Abdominal pain
Cloudy effluent
Send cloudy fluid to lab for C+S and prepare to administer abx
Abnormal outflow characteristics of peritoneal dialysis
Cloudy: infx
Bloody: expected during first exchanges; later = problem
Fecal/brown: intestinal perforation
Lower urinary tract infx AKA
Cystitis
Upper urinary tract infx AKA
Pyelonephritis
S+S of cystitis
Dysuria
Urinary frequency and urgency
Hematuria
Lower abdominal pain
Pyelonephritis S+S
N+V
Fever
Flank pain (costovertebral angle tenderness)
Meds of UTI
Abx
Antipyretics/analgesics
Antispasmodics
Pt teaching of UTI
Avoid bladder-irritating foods: caffeine, spicy foods, alcohol
Perineal hygiene
Avoid synthetic fabrics that seal in moisture
Empty bladder before and after sex
Acute nephrolithiasis tx
Administer pain meds
Strain pt’s urine
Administer antiemetics if needed
Encourage pt to move around
For CKD, what meds to avoid?
NSAIDs
On bladder scan, when is urinary retention indicated?
Amt > 100 mL
Arteriovenous fistula education
Avoid sleeping on arm w/ AVF or use creams/lotions on site
Avoid lifting heavy objects on side of AVF
Check fx of vascular access several times per day by feeling for thrill to access AVF patency
Avoid restrictive clothing/jewelry
Report S+S of infx and bleeding after dialysis
How is creatinine tested?
24 hr urine collection
Kidney disease is at risk for what 2 electrolytes?
Hyperkalemia
Hyperphosphatemia
Nephrotic syndrome
Increased glomerular basement membrane permeability leading to protein loss
S+S of nephrotic syndrome
Weight gain
Periorbital edema when walking -> edema
Ascites
Pallor
Decreased urine output
Fatigue
Irritability
Anorexia
Extreme proteinuria and albuminuria
Labs of nephrotic syndrome
Extreme proteinuria and albuminuria
Hyperlipidemia
