What should you do with a nitroglycerin patch found on a patient in cardiac arrest?

1. Leave it on to aid in heart function

2. Remove it prior to defibrillation

3. Apply another patch for enhanced treatment

4. Cut the patch off with scissors

The correct answer is: Remove it prior to defibrillation

In the context of a patient in cardiac arrest, it's essential to prioritize safe and effective resuscitation measures. A nitroglycerin patch, which is used to treat angina and manage chest pain, has the potential to cause hypotension (low blood pressure) if left in place during defibrillation, especially if other medications have been administered. Removing the nitroglycerin patch is crucial because it eliminates the risk of additional vasodilation (widening of blood vessels) which could exacerbate the patient's condition and interfere with the effectiveness of defibrillation. During defibrillation, any current administered can also potentially cause burns or other complications if the patch remains on the skin. Thus, to ensure patient safety and maximize the chances of successful resuscitation, the nitroglycerin patch must be removed prior to defibrillation.
