A client's total exposure to infrared rays should not last longer than?

  1. 5 minutes

  2. 10 minutes

  3. 20 minutes

  4. 30 minutes

The correct answer is: 5 minutes

Exposure to infrared rays can cause skin damage or irritation when sustained for a long period of time. Option A, 5 minutes, is the recommended maximum time for a client's exposure to infrared rays to prevent any potential harm. Options B, C, and D may seem close in time but they can still lead to overexposure and potential negative effects on the skin. It is important to follow the recommended time guidelines to ensure the safety and well-being of the client.
