NR507- Advanced Pathophysiology Final Exam Questions with Latest Update

Acute renal failure - Answer-Reversible Determining prognosis- kidneys respond to diuretic with good output; this indicates that kidneys are functioning well Acute Pyelonephritis - Answer-Diagnosing by clinical symptoms alone can be difficult; can be similar to cystitis Diagnosis established by: -Urine culture -Urinalysis (WBC casts indicates pyelonephritis, but may not always be present) -Signs/Symptoms -Complicated pyelonephritis requires blood cultures and urinary tract imaging Renal Calculi (Renal Stones) - Answer-Goals of Treatment: Manage acute pain Promote passage of stone Reduce size of stone Prevent new stone formation Chronic Renal Failure - Answer-Chronic Kidney Disease (CKD) is a progressive loss of renal function associated with systemic disease such as hypertension, diabetes mellitus (most significant risk factor), systemic lupus erythematosus or intrinsic kidney disease CKD stage is determined by estimates of GFR and albuminuria Who is a candidate for dialysis? - Answer-End-stage renal disease (ESRD) is the final stage of CKD with the number one cause being diabetes mellitus combined with hypertension. At this point, the patient is completely dependent on dialysis to survive. CKD is classified into five stages and is based on the patient's GFR rather than symptoms. Patients will need dialysis when the following symptoms are present: --Metabolic acidosis. --Hyperkalemia: Hyperkalemia in the presence of EKG changes (peaked T-waves) is an indication for dialysis. --Hyperkalemia by itself is not an indication for dialysis. --Drug toxicity: Drug toxicity due to the following drugs is an indication for dialysis and include salicylates, Lithium, Isopropanol, Methanol and Ethylene glycol). --Fluid volume overload that is not responsive to diuretics. --Uremic symptoms due to nitrogenous wastes in the blood stream. Stage I CKD - Answer-There is kidney damage with normal or elevated GFR 90-120
