A patient presents with persistent elevation of blood pressure readings during routine check-ups. Considering the pathophysiology and risk factors of hypertension, which of the following interventions is most appropriate for the nurse to prioritize in the care plan?

Hypertension is a chronic condition characterized by sustained elevation of systemic arterial pressure due to increased systemic vascular resistance, endothelial dysfunction, and dysregulation of the renin-angiotensin-aldosterone system, leading to long-term risks such as stroke, myocardial infarction, renal failure, and vascular remodeling. Rationale: A. Initiating multiple antihypertensive medications immediately without full assessment is inappropriate in routine hypertension management. Pharmacologic therapy should be individualized based on severity, comorbidities, and staged treatment guidelines, not started indiscriminately. B. Increased physical activity and a low-sodium diet directly reduce systemic vascular resistance, improve endothelial function, and decrease intravascular volume. These lifestyle modifications are first-line interventions in managing persistent hypertension and addressing underlying modifiable risk factors. C. Drastically reducing fluid intake is not indicated in hypertension unless specific comorbid conditions exist. Blood pressure is primarily influenced by sodium balance and vascular resistance rather than simple fluid restriction, making this intervention inappropriate. D. Monitoring blood pressure only during clinic visits fails to capture variability and may miss sustained hypertension or masked hypertension. Effective management requires home or ambulatory monitoring for accurate assessment and treatment adjustment.
