Q

Measurement: never diagnose HTN on one reading unless severe HTN or end-organ damage is present. Average measurements of >=2 readings on 2 separate occasions separated in time (days, weeks). AMBULATORY BP monitoring is the gold standard.

New onset HTN: once primary HTN is diagnosed, the next best step is to SCREEN for complications and comorbid conditions, which include HbA1c or fasting glucose, lipid panel, chemistry panel (serum Cr, BUN, K), ECG (screen for LV hypertrophy, Q waves for previous MI) and urinalysis (protein).
