What is the purpose of applying paste or jelly when running an ECG?

To improve the image quality
To cool the skin
To reduce skin resistance
To disinfect the skin

The correct answer is: To reduce skin resistance

Applying paste or jelly when running an ECG helps to reduce skin resistance. This is important because it allows for a better conduction of electrical signals from the heart to the ECG machine, resulting in a clearer and more accurate reading. Option A is incorrect because although it may seem logical to improve image quality, that is not the primary purpose of applying paste or jelly. Option B is incorrect because cooling the skin is not a necessary step in preparing for an ECG. Option D is incorrect because disinfecting the skin is typically done before applying the paste or jelly and is not the main purpose of its application. Overall, the purpose of applying paste or jelly is to enhance the accuracy and quality of the ECG reading by reducing skin resistance.
