Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
An AED is in use and has indicated that a shock is needed, the second rescuer should start compressions immediately after delivering the shock to the individual.
<h3>What is CPR?</h3>
This is referred to as Cardiopulmonary resuscitation and is an emergency lifesaving technique performed when the heart stops beating.This include series of compressions and artificial ventilation so as to ensure the brain functions are preserved.
In the case where an automated external defibrillator (AED) is used and indicates a shock is needed, it is best to give it immediately.
This should then be followed by compressions from the second rescuer which is therefore the reason why it was chosen as the correct choice.
