Question

When placing electrodes for an ECG test, which of these is the only factor that does not require consideration?

A) Patient's Age
B) Skin Preparation
C) Electrode Size
D) Electrode Placement Site

Answer 1

For ECG electrode placement, Patient's Age (A) is not a factor to consider; instead, focus on Skin Preparation, Electrode Size, and Electrode Placement Site for accurate ECG readings.

Step-by-step explanation:

When placing electrodes for an ECG test, the only factor that does not require consideration is A) Patient's Age. When conducting an electrocardiogram, it is crucial to ensure proper skin preparation to reduce impedance, choose the correct electrode size for secure contact with the skin, and identify the precise electrode placement site for accurate readings.

In contrast, the patient's age is not a variable that influences the physical setup of the electrode system for an ECG. The process of recording an ECG involves using a standard electrocardiograph, which can use 3, 5, or 12 leads, with the 12-lead requiring 10 electrodes placed in standard locations. A Holter monitor, used for continuous ambulatory electrocardiographs, also follows the same principles for electrode placement.
