Rationale: Identifying available resources and services is the priority action when developing a disaster response plan. This step is crucial as it helps the community understand what resources and services are already in place and what additional support may be needed during a disaster.

Rationale: The correct answer is A: Diabetes. Given the client's Native American ethnicity, high BMI, and vision changes, diabetes is the most crucial condition for the nurse to be aware of in the client's family history. Diabetes is strongly associated with vision problems, especially diabetic retinopathy. Glaucoma (choice B) is a condition that affects the optic nerve and can lead to vision loss but is not as directly linked to the client's BMI and ethnic background. Hypertension (choice C) can also impact vision, but in this case, diabetes takes precedence based on the client's profile. Brain tumor (choice D) is less likely to be related to the client's BMI, ethnicity, and vision changes compared to diabetes.
