Which of the following are the characteristics of masked hypertension?
- A. High home BP more than three days in a week
- B. Normal office BP and high home BP
- C. High office BP and normal home BP
- D. Normal office BP and normal home BP
Correct Answer: B
Rationale: Masked hypertension hides normal office readings (<140/90) clash with high home BP (>135/85), dodging detection, yet hiking cardiovascular risk. High home BP alone lacks context; high office with normal home is white-coat hypertension. Normal both ways is healthy; high both is overt hypertension. This sneaky pattern demands home monitoring to unmask, as office calm misses real-world spikes, pushing clinicians to dig deeper for treatment, a silent chronic threat exposed by dual settings.
