NURS 3100 Exam 1 Practice

Which statement represents the nurse's understanding as it relates to the potency of different narcotics?

Codeine is less potent than morphine; it will not produce allergic reactions Codeine is less potent than morphine; it will not relieve pain as well Morphine is more potent than codeine; a lesser dose will be required Morphine is more potent than codeine; it will produce more adverse effects

Correct Answer:

Morphine is more potent than codeine; a lesser dose will be required

Explanation:

The correct answer is C. This statement reflects the nurse's understanding of the potency of different narcotics. Morphine is indeed more potent than codeine, which means that a lesser dose of morphine will be required to achieve the same pain-relieving effect as codeine. Understanding the potency of different narcotics is crucial for nurses to ensure appropriate pain management for patients. Option A is incorrect because potency is not related to the potential for allergic reactions, but rather to the dose required to achieve a specific effect. Option B is also incorrect as it falsely states that codeine will not relieve pain as well, which is not accurate. Option D is incorrect as it incorrectly associates potency with producing more adverse effects.
