Which of the following is a part of skin preparation before performing an ECG?

Ensure skin is wet for better adhesion
Shave all body hair for clear electrode placement
Apply lotion to the skin before placing electrodes
Ensure the skin is dry and use an alcohol prep pad

The correct answer is: Ensure the skin is dry and use an alcohol prep pad

Ensuring that the skin is dry and using an alcohol prep pad is vital for effective skin preparation before performing an ECG. The primary goal is to create a clean surface for the electrode placement, ensuring good electrical contact. Using an alcohol prep pad helps to remove oils, dirt, and dead skin cells, reducing the potential for poor signal quality. When the skin is dry, the likelihood of obtaining accurate readings is increased, as moisture can interfere with the adhesive properties of the electrodes. It also minimizes the risk of skin irritation and ensures that the electrodes adhere properly throughout the procedure. This preparation is crucial for obtaining high-quality ECG traces and reliable data for assessment.
