Dialysis Technician Practice Exam

What is the normal pH range for a patient undergoing dialysis?

1. 6.8-7.2

2. 7.0-7.4

3. 7.35-7.45

4. 7.4-7.6

The correct answer is: 7.35-7.45

The normal pH range for a patient undergoing dialysis is 7.35 to 7.45. This range is critical for maintaining acid-base balance in the body, especially for individuals who are on dialysis, as their kidney function is impaired. A blood pH within this range indicates proper hydrogen ion concentration, essential for normal physiological functions. Dialysis patients are often at risk for acidosis or alkalosis due to the inability of their kidneys to excrete excess acids or bases. Therefore, monitoring and maintaining a pH level within this specific range is vital to prevent complications associated with imbalanced acid-base status. Values outside this range could indicate the need for adjustments in dialysis treatment or other interventions to restore balance. The other ranges provided do not align with the physiological norms for a healthy blood pH. The ranges of 6.8-7.2 and 7.4-7.6 are outside the typical acceptable levels for individuals undergoing dialysis, as they suggest either significant acidosis or slight alkalosis, which could be detrimental to the patient's health.
