A nurse needs to measure the blood pressure of a client with an electronic manometer. Which of the following advantages does an electronic manometer provide over an aneroid manometer or mercury manometer?
A) Ability to read gauge from any direction.
B) No stethoscope is required.
C) Inexpensive depending on quality.
D) Need for readjustment is eliminated.
B
Feedback:
An electronic manometer eliminates the need for a stethoscope. However, an electronic manometer requires a calibration check and readjustment every 6 months, unlike a mercury manometer which does not require readjustment. An electronic manometer is expensive depending on quality when compared to an aneroid manometer. A nurse can read the gauge of an aneroid manometer, not an electronic manometer, from any direction.
