CNA Training Practice Test

Thickened liquids are used when a resident has trouble swallowing (dysphagia). When swallowing is unsafe, thin liquids can go into the airway and cause choking or lung infection. Making liquids thicker slows the flow and gives the swallow time to close the airway, reducing the risk of aspiration. That’s why this option—residents with swallowing problems—is the best choice. The other options describe preferences or beliefs that don’t by themselves require changing liquid texture; thickened liquids are about safety in swallowing, not personal taste, dietary choices, or religious practices.
