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.
