Which of the following would be the correct procedure when taking the blood pressure of a hypertensive client who is monitored at the clinic once a week?

• A. Alternate arms for each visit
• B. Allow the client to rest for 5 minutes prior to taking the blood pressure.
• C. Not had caffeine within the last 5 hours
• D. Use manual rather than electronic devices

Answer: (B)

Resting before taking a blood pressure is essential for accuracy. For a hypertensive client seen weekly, you want a measurement that reflects the true resting pressure rather than a value raised by recent activity, stress, or discomfort. Having the client sit quietly for about five minutes with back supported, feet uncrossed and the arm at heart level allows the cardiovascular system to stabilize, producing a baseline reading that you can compare across visits. This consistency is key to evaluating control and guiding treatment adjustments. While other factors like avoiding recent caffeine and using a properly calibrated device matter, the most reliable way to obtain a valid reading at this visit is to ensure the patient rests beforehand.
