Which term is used to describe persistently elevated blood pressure with an unknown cause that accounts for approximately 90% of hypertension cases?
Secondary hypertension
Malignant hypertension
Primary hypertension
Accelerated hypertension
The Correct Answer is C
Choice A reason: Secondary hypertension has an identifiable cause, like renal disease, and accounts for about 10% of cases. Primary hypertension, with no known cause, is far more common, making this an incorrect term, as it does not describe the majority of hypertension cases seen clinically.
Choice B reason: Malignant hypertension is a severe, rapidly progressing form with organ damage, not the common form of hypertension. Primary hypertension, with no identifiable cause, represents 90% of cases, making this term incorrect, as it refers to a rare, acute condition, not the typical presentation.
Choice C reason: Primary hypertension, also called essential hypertension, has no identifiable cause and accounts for approximately 90% of cases. It develops gradually, influenced by genetics and lifestyle, making this the correct term to describe the most common form of persistently elevated blood pressure.
Choice D reason: Accelerated hypertension involves rapid blood pressure elevation with organ damage, not the typical chronic, idiopathic form. Primary hypertension, without a known cause, is the predominant type, making this term incorrect, as it describes a severe, less common variant of hypertension.

Correct Answer is B
Explanation
Choice A reason: Increasing blood pressure is not the goal of antihypertensive therapy, which aims to lower blood pressure to prevent organ damage. Hypertension increases cardiovascular risk, and therapy reduces pressure, not raises it, making this an incorrect goal for managing Mr. Carter’s condition.
Choice B reason: The primary goal of antihypertensive therapy is to reduce cardiovascular complications, such as stroke, myocardial infarction, and heart failure, by lowering blood pressure. This decreases vascular strain and organ damage, improving long-term outcomes, making it the correct goal for Mr. Carter’s hypertension management.
Choice C reason: Hypertension is a chronic condition, and antihypertensive therapy manages, not cures, it. Medications control blood pressure but do not eliminate the underlying pathophysiology, making a permanent cure an incorrect goal, as ongoing treatment and lifestyle changes are typically required.
Choice D reason: Antihypertensive therapy complements, not eliminates, lifestyle changes like diet and exercise, which are essential for blood pressure control. Eliminating lifestyle changes is not a goal, as they enhance therapy efficacy, making this an incorrect objective for Mr. Carter’s treatment plan.
