Answer to Question 1

Correct Answer: 2
Rationale: A drug that is more potent will produce a therapeutic effect at a lower dose. Potency does not mean the drug will produce more adverse effects. Less potent narcotics can be very effective with pain relief. The potency of a drug is not related to its ability to cause an allergic reaction.

Answer to Question 2

Correct Answer: 4
Rationale: The mean effective dose predicts how 50 of the population will respond to the average dose of the drug. Some patients will require more or less of the drug. The mean effective dose is not related to ethnicity. The mean effective dose does not predict how many patients will experience severe side effects from the drug. The mean effective dose does not predict that 50 of patients will not experience any effect of the drug.
