What should be confirmed if the initial blood pressure reading is greater than 139/89?

When the initial blood pressure reading is greater than 139/89, it is essential to recheck the blood pressure later during the exam. This step is critical because blood pressure can vary significantly based on a number of factors, including the patient's state of anxiety or discomfort during the examination. Confirming the reading with a subsequent measurement allows for a more accurate assessment of the individual's blood pressure status.

This approach aligns with the guidelines for diagnosing hypertension, which typically requires multiple readings to ensure an accurate diagnosis rather than solely relying on one elevated reading. Therefore, taking the time to recheck blood pressure ensures that any potential false elevation due to situational factors is minimized, and provides a clearer picture of the individual’s health.
