Final answer:
First, the nurse should remove any medication patches before using an AED on an unresponsive and pulseless person to prevent potential burns during defibrillation. CPR is also recommended prior to AED use. so, option c is the correct answer.
Step-by-step explanation:
When witnessing a person fall and become unresponsive and pulseless, and an automated external defibrillator (AED) is available for use, the nurse would remove any medication patches first before administering defibrillation. This is to prevent burns and ensure that the electric shock is delivered efficiently. An AED is designed to be used by both medical personnel and laypersons, providing verbal instructions and automatically diagnosing the heart rhythm before applying a shock with appropriate energy and waveform. In many cases, CPR (cardiopulmonary resuscitation) is recommended before the use of an AED to sustain blood flow to vital organs until the heart rhythm can be restored.
When witnessing a person fall and become unresponsive and pulseless, the nurse's first action when an automated external defibrillator (AED) is available would be to remove all jewelry. This is important because metal jewelry can interfere with the delivery of the electrical shock from the AED.
