Adult Renal/Electrolytes Flashcards
Urolithiasis
presence of calculi (stones) in the urinary tract
Nephrolithiasis
- kidney stones
- CVA tenderness and flank pain
Ureterolithiasis
stones in the ureter
Symptoms of renal calculi
- hematuria
- renal colic (unilateral pain spasms in flank)
- severe radiating pain
- nausea/vomiting/sweating
- hypertension
Renal failure causes _____volemia
- hypervolemia
- If the kidneys are failing, they are not effectively making urine
Respiratory acidosis
- inability to expel carbon dioxide
- airway obstruction
- decreased ventilation
SIADH
- can lead to hyponatremia
- hemodilution
- increased urine gravity
- too much ADH
- ADH causes water retention, too much water is retained
- no peripheral edema
- bc fluid retained across all areas
- blood pressure is mostly normal
SIADH care
- monitor for changes in mental status and level of consciousness
Rhabdomyolysis
- breakdown of muscle
- releases contents into bloodstream
- diagnose through serum creatine kinase levels
- give IV fluids to prevent kidney damage
- give statins
Pyelonephritis
- similar to cystitis and fever
- tachycardia
- flank pain
- Treatment is antibiotics and hydration
Acute kidney injury (AKI) causes
- prerenal (not kidney related) causes
- hypovolemia/dehydration! (most common)
- sepsis
- shock
- burns
Intrarenal/intrinsic (inside kidney) causes - allergy
- embolism/thrombosis
- nephrotoxic agents
- postrenal causes
- urine flow obstruction
- stones, strictures (abnormal narrowing)
- tumor
- hypotension = decreased blood flow to kidneys
Acute kidney injury (AKI) findings
- risk for hyperkalemia
- metabolic acidosis
- reduce sodium and potassium
- oliguria
- treatment is IV fluid challenges
- daily weights
- treatment is IV fluid challenges
- MONITOR CREATINE TO SEE EVIDENCE OF KIDNEY INJURY
Chronic kidney disease
- causes hyperphosphatemia
- give Sevelamer
- decreases testosterone (hypogonadism)

- hypertension
- early
- lose lots of salt so may need to increase salt intake
- advanced
- low sodium diet
- constipation = increase fiber for relief
- hematuria
- berry aneurysm
- can cause hemorrhagic stroke
- only cure is kidney transplant
- dry heat for pain relief
- avoid NSAIDS
Dialysis disequilibrium syndrome (DDS)
- caused by rapid removal of urea
- headache and nausea is a concern!
End-stage renal disease (ESRD)
- Low hemoglobin levels

- prolonged QT intervals
Prostatic hyperplasia
- weak urinary stream
- nocturia
- dribbling in underwear
- difficulty starting stream
- progressively worse over 4 years
- leads to kidney damage
- give Finasteride
- avoid caffeine
TURP
- procedure for prostatic hypertrophy or prostate cancer
- may cause sexual dysfunction
- retrograde ejaculation
- large lumen urinary catheter is placed
- significant complication is HEMORRHAGE
- MONITOR FOR SHOCK
- tachycardia
- restlessness
Causes of hypomagnesemia
- alcoholism
- diarrhea
- diuretics
- annorexia
Causes of hypermagnesemia
- renal failure
- antacids
- lithium therapy
- adrenal insufficiency
- hypothyroidism
Hyperemesis gravidarum
- pregnancy complication
- nausea, vomiting, weight loss
- vomiting puts risk for hypokalemia
- hypokalemia associated with metabolic alkalosis due to vomiting
renal failure will be at risk for _____kalemia
hyperkalemia
renal failure hemodialysis dietary modifications
- low sodium, phosphorus, calcium, and potassium
- blueberries, cream of wheat, coffee is good
uremia
- buildup of waste products as a result of untreated kidney failure
- waste products from protein breakdown
- protein restriction helps
Ulcerative colitis flare-ups
- ten or more episodes of diarrhea per day
- loses a large volume of fluid, resulting in deficient fluid volume
Cranberry juice
used for UTI prevention, not UTI treatment
Acute glomerulonephritis s/s
- proteinuria
- hematuria
- periorbital edema
- oliguria –> hypervolemia –> weight gain
- cola/tea-colored urine
- adverse effect
- severe hypertension
- cause’s encephalopathy
- severe headache = monitor BP
- severe hypertension
- decreased glomerular filtration rate (GFR)
Acute glomerulonephritis (AGN) diagnosis
- Renal insufficiency is the hallmark of AGN
- ↑ BUN and ↑ creatinine.
Hepatic encephalopathy
- monitor mental status/fall risk
- increased serum ammonia level
- give lactulose (depletes ammonia)
- give Rifaximin (decrease production of ammonia)
- DO NOT give benzodiazepines
- avoid hypokalemia as is contributes to ammonia production
Dumping syndrome
- complication after gastric bypass surgery
- rapid emptying of food into the small bowel
- resulting in hypotension
- abdominal pain, diarrhea, nausea
- tachycardia
- risk of hypoglycemia.
Dumping Syndrome care
- avoid simple carbohydrates (refined sugars)
- foods include candy, cookies, pastries, cola
- increase protein and complex carbohydrates
- rice cereal, chicken breast, scrambled eggs, potatoes, whole grain, pasta
- gives body time to absorb before dumping
