Answer to Question 1

ANS: A
The initial dose is sometimes given in a higher amount, a loading dose, to reach a therapeutic level in the blood more quickly, thus making the drug more effective.
An average effective dose is not used to evaluate the response to the medication.
The initial dose does not indicate that the subsequent doses will be one half of the initial dose.
All patients do not receive a high initial dose of a medication.

Answer to Question 2

ANS: B, C, E
Affinity does refer to the strength of the attraction between a drug and its receptor, drugs with high affinity are strongly attracted to their receptors, and the affinity of a drug for its receptors is reflected in its potency.
Affinity and intrinsic activity are independent properties.
Drugs with low affinity are weakly attracted to their receptors.
