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>

The use of chlorination to treat drinking water, which began in 1913, reduces the incidence of waterborne diseases.
Based on the dosage available, the amount in mL of the drug required is 22.5 mL.
<h3>What is drug dosage?</h3>
Drug dosage refers to the amount of drug that should be taken by a patient in order to produce effective pharmacodynamic results.
The dosage of the drug to be given is 45 mEq.
The dosage available is 30 mEq in 15 mL.
In order to give this required dosage the amount in mL required is calculated as follows:
30 mEq is in 15 mL
45 mEq will be in x mL
x = 45 * 15/30
x = 22.5 mL
In conclusion, drug dosage refers to the amount of drug required to produce good results in the patient.
