Question 2
A patient asks why he must take a loading dose for the first dose of his prescribed drug and then take lower doses after that. What is your best response?
a. The loading dose allows the first dose of this drug to get into your bloodstream faster and because it stays in the bloodstream a long time, you can take lower doses after that.
b. The first dose of a drug has to be higher to reach the bloodstream because the liver destroys it before it has a chance to start its action and work for you.
c. By taking the highest dose first and just once, you are reducing the likelihood of having a bad reaction or other side effects to this drug.
d. This schedule helps by ensuring that the drug is having an effect even if you forget to take the rest of the doses.
