NHA Certified Clinical Medical Assistant (CCMA)Clinical Patient CareMedium
A medical assistant is preparing a patient for an electrocardiogram (ECG). The patient has excessive chest hair. Which of the following actions should the medical assistant take to ensure proper electrode adhesion?
- AShave the areas where electrodes will be placed.
- BSecure electrodes with additional medical tape.
- CRub the skin vigorously to remove hair.
- DApply extra gel to the electrodes.
Show answer & explanationAnswer & explanation
Correct answer: A. Shave the areas where electrodes will be placed.
Excessive chest hair can prevent proper electrode contact with the skin, leading to artifact and poor ECG tracing quality. Shaving the areas where electrodes will be placed ensures good skin contact and accurate readings.
Why the other options are wrong
- B. Additional tape might help secure the electrode, but it doesn't resolve the poor electrical contact caused by hair.
- C. Vigorous rubbing can irritate the skin and may not remove enough hair for proper adhesion.
- D. Extra gel can cause electrodes to slide and does not effectively address the barrier of hair.
ECG Electrode Prep
Proper skin preparation, including hair removal, is crucial for good electrode adhesion and minimizing artifact during an ECG, ensuring accurate electrical signal transmission.
- Hair interferes with electrode contact.
- Shaving ensures direct skin contact.
- Poor contact leads to artifact.
Memory trick: Smooth Skin for Clear Signals, Shave if Hairy.
