Final answer:
A CNA should first check if the resident is using visual aids and verify there are no immediate and obvious issues before reporting the change in vision to a nurse or a healthcare provider for further assessment.
Step-by-step explanation:
When a resident complains that he cannot see clearly while watching TV, the first action a Certified Nursing Assistant (CNA) should take is to assess the situation. The CNA should ask the resident if he is wearing any visual aids like glasses or contact lenses, and if he is and the problem persists, or if he does not normally wear any, the CNA should then check the resident's eyes to see if there is an obvious issue.
If the resident's visual aids are not helping or if there is a sudden change in vision without a clear cause, the CNA should report the situation to a nurse or a healthcare provider to determine the next steps, such as scheduling an appointment with an optometrist. It's important for the CNA to act with empathy and professionalism, reassuring the resident that they will assist them and take the necessary steps to address their concern.
