Question: 1 / 400

When preparing a patient for Holter monitoring, what action should an MA take to ensure accurate electrode placement?

Apply lotion to the skin

Moisten the skin with water

Allow the skin to air dry

Vigorously dry the skin prior to placement

When preparing a patient for Holter monitoring, it is important for an MA to ensure the skin is clean and dry prior to electrode placement. This is because lotion (Option A) can create a barrier between the electrode and the skin, potentially causing inaccurate readings. Moistening the skin with water (Option B) may also interfere with the electrode's adhesion to the skin. Allowing the skin to air dry (Option C) may take too long and leave the skin slightly damp, affecting the electrode's ability to stay in place. Vigorously drying the skin prior to placement (Option D) ensures that the skin is completely dry and provides the best surface for the electrode to adhere to, increasing the accuracy of the monitoring.
