Question 2 of 5
For the statements regarding treatment of hypertension in the questions below, select the MOST appropriate treatment option. (Assuming a newly diagnosed patient with no additional context provided)
Correct Answer: A
Rationale: Without specific patient details, Ramipril (an ACE inhibitor) is a common first-line option for hypertension, especially in younger patients or those under 55, per guidelines like NICE.
