Final answer:
To apply cardiac rhythm monitoring electrodes, the nurse must make sure the electrode gel is dry and avoid using soaps to prevent skin irritation. Chest hair may need to be clipped if it interferes with electrode placement.
Step-by-step explanation:
When applying cardiac rhythm monitoring electrodes, the nurse must first make sure that the electrode gel is dry. This is to ensure good electrical conductivity between the electrodes and the patient's skin. Applying a moist gel is not necessary as it may interfere with the quality of the electrical signal. The nurse should also avoid soaps to prevent skin irritation and clip the chest hair if needed to ensure proper electrode placement.
