Patient Data Select from Word Choices to complete the sentence. The thiazide diuretic works to decrease the client's blood pressure by ______, and the angiotensin converting enyzme (ACE) inhibitor works to decrease the client's blood pressure by ________ and _______
Explanation & Rationale
Increasing heart rate: Increasing heart rate is not the mechanism of thiazide diuretics or ACE inhibitors. It would raise blood pressure by increasing cardiac workload. Effective antihypertensives aim to lower or stabilize heart rate, not increase it. Reducing stroke volume: Thiazide diuretics reduce stroke volume by lowering blood volume through sodium and water excretion. This decreases cardiac output and helps lower blood pressure, particularly in volume-sensitive hypertension. Suppressing the appetite: Suppressing appetite is unrelated to the action of thiazide diuretics or ACE inhibitors. These drugs target fluid balance and vascular tone, not the central nervous system mechanisms that regulate hunger. Decreasing serum sodium levels: Both thiazide diuretics and ACE inhibitors contribute to decreased serum sodium levels, which helps lower blood volume. This reduction supports blood pressure control but must be monitored to avoid hyponatremia. Reducing systemic vascular resistance: ACE inhibitors lower blood pressure by reducing systemic vascular resistance through vasodilation. Blocking angiotensin II prevents arterial constriction, easing the workload on the heart and lowering afterload.
