All contact surfaces must be disinfected after every client session to prevent cross-contamination.

Question 2: Which pH range is considered normal for the human colon environment?

4.5–5.5
7.5–9.0
2.0–3.5
5.5–7.5 (Correct answer)

Correct answer: 5.5–7.5

The colonic pH ranges from approximately 5.5 to 7.5, with more acidic conditions in the proximal colon due to fermentation and more neutral conditions distally.

Question 3: A client mentions they took a stimulant laxative the evening before their colonic appointment. What is the most important concern?

The treatment should be doubled in duration to compensate
The colon may be overly stimulated, increasing risk of cramping and electrolyte loss (Correct answer)
Stimulant laxatives improve outcomes by pre-cleansing the colon
Stimulant laxatives have no interaction with colonic hydrotherapy

Correct answer: The colon may be overly stimulated, increasing risk of cramping and electrolyte loss
