What is the purpose of checking dialysate temperature?

• A. To prevent infection
• B. To avoid overheating
• C. To prevent hemolysis or crenation
• D. To adjust color

Answer: (C)

Maintaining an appropriate dialysate temperature protects red blood cells from temperature-related stress during the dialysis session. If the dialysate is too hot or too cold, red blood cells can be damaged, leading to hemolysis (rupture) or crenation (shrinking). Keeping the dialysate close to body temperature reduces thermal and osmotic stress on the blood as it passes through the dialyzer, helping preserve cell integrity and stability for the patient.
