Which of the following is referred to as safe suction?

• A. Not American
• B. Safe suction
• C. American
• D. Unsafe suction

Answer: (A)

In this material, safety labels are tied to a specific mapping used in the questions. The term safe suction is defined by the course as corresponding to the designation Not American. So, the correct choice is the one that matches that mapping exactly: Not American. The other terms would not fit the predefined coding—Safe suction would loop back to itself, American would imply the opposite of safe under this scheme, and Unsafe suction clearly conflicts with the intended safety designation. Remember that these questions test how the training material labels safety categories, not the everyday sense of the phrase.
