The nurse is explaining to a patient the difference between hemodialysis and continuous renal replacement therapy (CRRT). What statement by the patient leads the nurse to determine that additional education is needed?

A. "CRRT causes less electrolyte changes.": Continuous renal replacement therapy is slower and continuous, which results in gradual removal of fluids and solutes, minimizing rapid shifts in electrolytes and hemodynamic instability. This statement accurately reflects the advantage of CRRT over intermittent hemodialysis. B. "CRRT is faster than hemodialysis.": CRRT is intentionally slow and continuous, typically running 24 hours a day, whereas conventional hemodialysis is intermittent and completed over 3–5 hours. The slower rate of CRRT reduces rapid fluid and solute shifts, which is particularly important for unstable patients. C. "CRRT is used for hemodynamically unstable patients.": CRRT is preferred for patients who cannot tolerate rapid fluid removal or abrupt blood pressure changes associated with traditional hemodialysis. This statement is accurate and reflects appropriate patient selection. D. "CRRT is used to treat acute kidney injury.": CRRT is commonly employed in the management of acute kidney injury, especially in critically ill patients in the ICU. This statement correctly identifies one of the primary indications for CRRT.
