A patient with newly diagnosed hypertension presents with elevated blood pressure readings and reports feeling fatigued. Which of the following lifestyle modifications should the nurse prioritize in the patient's care plan to address hypertension?

Hypertension is a chronic condition characterized by sustained elevation of systemic arterial pressure, driven by increased systemic vascular resistance, endothelial dysfunction, and dysregulation of the renin-angiotensin-aldosterone system, leading to long-term cardiovascular, renal, and cerebrovascular complications if not controlled. Rationale: A. A diet high in saturated fats and sugars promotes atherosclerosis, endothelial dysfunction, and increased arterial stiffness. This worsens systemic vascular resistance and contributes to further blood pressure elevation. It is contraindicated in hypertension management. B. Relying solely on antihypertensive medications without lifestyle modification is incomplete management. While drugs control blood pressure, they do not address modifiable risk factors such as obesity, diet, and inactivity. Comprehensive care requires both pharmacologic and lifestyle interventions. C. Increased physical activity improves vascular endothelial function and reduces systemic vascular resistance, while a low-sodium balanced diet decreases fluid retention and blood volume. This combination directly targets the pathophysiology of hypertension and is the most effective lifestyle intervention. D. Increased alcohol consumption elevates sympathetic nervous system activity, raises blood pressure, and contributes to poor cardiovascular outcomes. It worsens hypertension and is not a therapeutic stress management strategy.
