Final answer:
If uncertain about a blood pressure reading, wait 1 to 2 minutes before retaking. Multiple measurements are necessary for an accurate diagnosis because factors like stress can affect blood pressure. For consistent monitoring, digital home monitors are recommended.
Step-by-step explanation:
If you are unsure of a blood pressure reading, it's recommended to wait at least 1 to 2 minutes before taking another measurement. Blood pressure can fluctuate due to various factors, including stress, exercise, and the time of day. To get an accurate diagnosis of hypertension, several measurements are needed. People with "white coat disease" may experience temporary increases in blood pressure in a medical setting. For home monitoring, digital blood pressure monitors are easy to use and provide valuable data for doctors.
Healthy blood pressure ranges are typically lower than 120 mmHg for systolic and lower than 80 mmHg for diastolic. However, measurements should be taken repeatedly over time to accurately assess one's blood pressure levels. When using a blood pressure monitor, it's important to be relaxed, seated, and have the arm at heart level to ensure correct readings.
