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>
"Since the intervention is designed to reduce the number of days that a resident receives antibiotics for bacterial pneumonia, the rate of antibiotic days of therapy per 1,000 resident days is most likely to change if the intervention is effective. Because this effort is not trying to reduce antibiotic starts for bacterial pneumonia, neither the rate of antibiotic starts nor the proportion of antibiotics given for pneumonia may change as a result of the intervention. Although the rate of antibiotic use by class might change if one antibiotic class is most commonly used to treat bacterial pneumonia, this measure wouldn't be the best choice for evaluating the new guideline."
