The nurse administers narcotics to surgical patients. Which statement represents the nurse's best understanding as it relates to the potency of different narcotics?
1. Codeine is less potent than morphine; it will not produce an allergic reaction.
2. Morphine is more potent than codeine; a lesser dose will be required.
3. Morphine is more potent than codeine; it will produce more adverse effects.
4. Codeine is less potent than morphine; it will not relieve pain as well.
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.
