Cardiopulmonary Resuscitation (CPR) Practice 2026 - Free CPR Practice Questions and Study Tips.

The correct answer highlights that alcohol should never be used as a substitute for contact gel during defibrillation procedures due to its flammable properties and the potential for adverse reactions with electrical currents. The main purpose of contact gel is to enhance conductivity between the defibrillation pads and the skin, ensuring effective delivery of the electrical shock to underlying cardiac tissue.

Using alcohol instead of appropriate gel can create a serious safety hazard, as it may catch fire if an electrical device is activated in its presence. Furthermore, alcohol can also dry out the skin, reducing conductivity and effectiveness, increasing the risk of inadequate defibrillation.

In contrast, other options, while not ideal, are less dangerous. Saline solution, for instance, is conductive and can facilitate the electrical current but may not adhere properly to the skin. Water, while better than alcohol in terms of safety, could also decrease the efficacy of the shock if not used in significant quantity. Antiseptic wipes could potentially leave a residue that may interfere with conductivity. None of these alternatives equate to the effectiveness and safety of a properly formulated defibrillation gel, but alcohol poses particular risks that must be avoided.
