Considering the patient's current medication regimen and clinical findings, what is the most likely rationale for the combination of lisinopril, amlodipine, and hydrochlorothiazide in the management of their hypertension?
To manage potential side effects of each medication by using them in combination. To treat a specific form of secondary hypertension diagnosed in the patient. To provide a synergistic effect by using multiple medications from the same drug class. To address different mechanisms of blood pressure control by targeting the renin-angiotensin system, calcium channels, and diuretic effects.
