The signs of a hypertensive emergency would MOST likely be delayed in patients who:

• A. Have chronic hypertension.
• B. Regularly take illegal drugs.
• C. Have had a stroke in the past.
• D. Are older than 40 years of age.

Answer: (A)

When the body has chronic hypertension, the vasculature and brain adapt to consistently higher pressures. This adaptation shifts autoregulation so that perfusion remains adequate at higher mean arterial pressures, meaning an acute rise in blood pressure may not produce dramatic new symptoms right away. In other words, the signs of a hypertensive emergency can be delayed because the system has become tolerant to elevated pressures and clues of end-organ damage don’t appear immediately. In contrast, sudden, marked blood pressure spikes from illegal drug use are typically accompanied by rapid, noticeable signs; a history of stroke doesn’t inherently delay new symptoms, and age over 40 does not determine how quickly signs appear.
