The nurse is working in an urgent care clinic that has standardized treatment protocols for implementation by nursing staff. After reviewing the history. physical assessment, and vital signs for a 60-yr-old patient as shown in the accompanying figure, which action should the nurse take first?

Rationale: A. Important, but not the priority until urgent causes (like hypoglycemia or hyperglycemia) are ruled out. B. In a 60-year-old with diabetes or possible symptoms such as dizziness, vision changes, or abnormal vitals, hypoglycemia/hyperglycemia must be ruled out immediately since it can be life-threatening if untreated. This is the priority action. C. Ear irrigation is not urgent and does not address the potentially serious underlying cause of the patient’s symptoms. D. The patient’s BP has already been measured. While rechecking may be necessary, it is not the first priority over assessing blood glucose in a potentially unstable diabetic patient.
