What would be the best source of drug information for a nurse?
- A. Drug Facts and Comparisons
- B. A nurses drug guide
- C. A drug package insert
- D. The Physicians Drug Reference (PDR)
Correct Answer: B
Rationale: A nurses drug guide provides nursing implications and patient teaching points that are most useful to nurses in addition to need-to-know drug information in a very user friendly organizational style. Lippincotts Nursing Drug Guide (LNDG) has drug monographs organized alphabetically and includes nursing implications and patient teaching points. Numerous other drug handbooks are also on the market and readily available for nurses to use. Although other drug reference books such as Drug Facts and Comparisons, PDR, and drug package inserts can all provide essential drug information, they will not contain nursing implications and teaching points and can be more difficult to use than nurses drug guides.
