Which statement accurately describes diagnosing hypertension?

• A. A single office measurement is sufficient for diagnosis
• B. Diagnosis usually requires multiple readings across 2-3 visits
• C. Diagnosis can be made only with 24-hour ambulatory monitoring
• D. Diagnosis is based on symptoms alone

Answer: (B)

Diagnosing hypertension relies on repeated evidence of elevated blood pressure, not a single reading or symptoms. Blood pressure fluctuates from day to day and even within a single visit due to stress, activity, caffeine, and measurement technique. By taking multiple readings across two to three visits (or using home/ambulatory measurements that confirm sustained elevation), you distinguish true, persistent hypertension from transient spikes or white coat effects. Symptoms are not reliable indicators, since many people with high blood pressure feel fine. Ambulatory or home monitoring is especially helpful when the diagnosis is uncertain or to separate white coat from true hypertension, but isn’t required in every case. This approach—multiple readings over several visits—best reflects how hypertension is diagnosed.
