Concepts Exam #3 Ch 68 Flashcards
Causes of decreased renal perfusion
Age (65) Obstruction (crystals, casts, tumors) Diuretics (hard on kidneys) Pressors Cyclosporine (toxic to kidneys Dye (CT dye is toxic to kidneys) Glucophage (increase risk of lactic acidosis)
Normal BUN
7 to 20 mg/dL
Normal Creatinine
0.5 to 1.2 mg/dL
Prerenal (Patient is dry)
20:1 ratio
Renal (Patient has kidney disease)
10:1 ratio
Calculation is BUN/Creatinine
If answer is 10 patient is renal, if answer is 20 patient is prerenal
Acute Kidney Injury (AKI)
Rapid reduction in kidney function resulting in a failure to maintain fluid and electrolytes
azotemia
The retention and buildup of nitrogenous wastes in the blood
Hyperkalemia
Peaked t waves, prolonged PR, loss of p-wave, the widened QRS
Cardiac Complicatoin
Pericarditis
Pulmonary Edema
Heart failure
Hyperlipidemia
Hematologic changes
bleeding
bruising
Dietary Restrictions
Low sodium, low potassium, low protein
Education needs
Diet, Exercise
Nursing interventions
Monitor fluids for overload or decrease Vital signs Breath sounds Monitor electrolytes Assess for abdominal pain Monitor hygiene and bleeding
Complications of Renal Failure
Neurologic (confusion, peripheral neuropathy)
Cardiovascular (hyperkalemia, dysrrhythmias)
Pulmonary (pleural fusions)
GI (ulcers, malabsorbsion, nausea)
Hematologic (hematuria)
Endocrine (acidosis)
General (muscle weakness)
Psych (denial, dependency, non-compliance)
