Q. A 45-year-old man with a history of hypertension presents to your primary care clinic for a follow-up visit. He has been on antihypertensive medication (lisinopril 10 mg daily) for the past six months. His temperature is 98.6°F (37°C), pulse is 90 beats per minute, blood pressure is 175/100 mmHg and respiratory rate is 14 per minute. On repeated measurements, his blood pressure is consistently elevated at 175/100 mmHg. Physical examination is unremarkable. The patient reports adherence to his medication and a healthy lifestyle with regular exercise and a low-sodium diet. What would be your next steps in managing this patient's hypertension?
