Question 5 of 5
Which ONE of the following prescriptions would NOT be 1st line treatment for a 51-years old Caucasian male who has just been diagnosed with hypertension requiring treatment. No past medical history. Blood pressure 150/92 mmHg.
Correct Answer: D
Rationale: For a Caucasian male under 55 with no comorbidities, ACE inhibitors (e.g., lisinopril, ramipril) are first-line per guidelines like NICE. Enalapril is an ACE inhibitor but less commonly used as a starting dose compared to lisinopril or ramipril, making it not a typical first-line choice.
