A nurse is reinforcing teaching with a client about monitoring her blood pressure at home with a digital device. Which of the following statements by the client indicates an understanding of the teaching?

This statement shows that the client understands the threshold for high blood pressure readings. A blood pressure reading of 140/90 mmHg or higher is considered elevated or hypertensive. It is important for the client to be aware of this value and to seek medical attention or follow the prescribed management plan if their blood pressure exceeds this threshold. The hand should be supported at the level of the heart or positioned comfortably during blood pressure measurement, but it does not need to be specifically 6 inches below the heart. Consistency in the timing of blood pressure measurements is important for accurate monitoring. It is generally recommended to measure blood pressure at the same time each day to account for variations that can occur throughout the day. The blood pressure cuff should be snug but not too tight around the upper arm. It should fit comfortably and securely to ensure accurate readings.
