Which diuretic is FIRST-LINE for managing volume overload in AKI patients who are not yet requiring RRT?
Answer: Furosemide (loop diuretic)
Furosemide is the first-line diuretic for volume overload in AKI; high doses may be needed in patients with reduced tubular function.
A dialysis patient presents to the ICU with peaked T waves and widened QRS on ECG. Potassium is 7.2 mEq/L. What is the IMMEDIATE first step?
Answer: Give IV calcium gluconate
IV calcium gluconate immediately stabilizes the cardiac membrane without lowering potassium, buying time for definitive treatment.
Which finding indicates successful AKI recovery and readiness to discontinue RRT?
Answer: Urine output >500 mL/day spontaneously
Spontaneous urine output >500 mL/day indicates recovering tubular function and is a key criterion for considering RRT discontinuation.
Which medication dose adjustment is required in a critically ill patient with AKI (eGFR 15 mL/min)?
Answer: Vancomycin — reduce dose and extend dosing interval
Vancomycin is renally cleared; dose reduction and extended dosing intervals with TDM are required in AKI to avoid toxicity.
Rhabdomyolysis-induced AKI is BEST prevented by which intervention?
Answer: Aggressive IV fluid resuscitation with normal saline
Aggressive IV hydration with isotonic saline is the cornerstone of rhabdomyolysis management, diluting myoglobin and maintaining urine flow.
An ACNP is initiating CRRT for a patient in septic shock with AKI. Which CRRT dose is recommended per KDIGO guidelines?
Answer: 20–25 mL/kg/hr effluent
KDIGO guidelines recommend a delivered CRRT dose of 20–25 mL/kg/hr; higher doses do not improve outcomes.
