Correct Answer is D
Explanation
." Eye health is an essential aspect of overall health, and many eye disorders and diseases can be asymptomatic. The American Optometric Association (AOA) recommends that adults aged 18-64 should have a comprehensive eye exam at least every two years. After age 65, the frequency of eye exams should be increased, depending on the individual's eye health status. During an eye exam, the optometrist or ophthalmologist evaluates the client's visual acuity, peripheral vision, and intraocular pressure, as well as examines the internal and external structures of the eyes to detect any abnormalities. The assessment of the retina is particularly important as it can reveal the presence of chronic diseases such as diabetes, high blood pressure, and macular degeneration.
Correct Answer is A
Explanation
The correct answer is choice A, "Are you having any thoughts about hurting yourself?" This is the most important question to ask because it assesses the client's risk for suicide, which is a potential complication of depression. The nurse should ask this question before exploring other issues related to the client's depression. If the client expresses suicidal thoughts or intent, the nurse should initiate appropriate interventions to ensure the client's safety.
