A team of community health nurses is considering the implementation of new programs in their community, and they are formulating research questions. Which of the following should represent a T in their PICOT questions? (Select All that Apply.)

A. This statement pertains to the client's current state but does not represent an intervention taken by the nurse. It would be more appropriate for documentation in a narrative or assessment section rather than the intervention component.
B. This entry describes an outcome or finding related to the client’s condition rather than an intervention. While it is important data, it does not reflect an action taken by the nurse and thus would not be included in the intervention section.
C. It clearly describes a specific action taken by the nurse (administering medication) in response to the problem (nausea and vomiting). It directly addresses the client's needs and reflects an intervention aimed at treating the identified problem.
D. This statement indicates the problem or symptom that the client is experiencing but does not describe an intervention. While it is critical information for understanding the client’s condition, it belongs in the problem or assessment section rather than the intervention component.

A. Glaucoma typically affects peripheral vision first and may lead to tunnel vision as the disease progresses. While it can cause significant vision loss, it is not primarily characterized by a decrease in central vision.
B. Macular degeneration specifically affects the central part of the retina (the macula), leading to a loss of central vision while peripheral vision remains intact. It is the most common cause of vision loss in older adults and directly correlates with the symptom described.
C. Diabetic retinopathy primarily affects the blood vessels in the retina and can lead to various vision problems, including blurred vision, floaters, and even blindness. However, it does not exclusively cause a decrease in central vision; it often affects both central and peripheral vision.
D. Cataracts typically cause cloudy or blurred vision but do not specifically lead to a decrease in central vision alone. They may affect overall vision clarity, including both central and peripheral vision, but the primary symptom is a general haziness rather than a focused loss of central vision.
