Clinical Medical Assistant Exam Practice Question

Correct Answer: A

Rationale: Applying electrode gel enhances the electrical connection between the skin and the electrodes, ensuring accurate readings from the EKG/ECG. This conductive gel reduces impedance, allowing for clearer signal transmission.

Option B is incorrect; the gel does not serve to cool the skin but rather to facilitate conductivity. Option C, while skin irritation can occur, is not the primary purpose of the gel, which focuses on signal quality. Option D is also misleading; although the gel may help with adhesion, its main function is to improve electrical conductivity, not just to ensure the electrodes stick.
