Correct Answer is B
Explanation
Choice A rationale
While "Drug Facts and Comparisons" is a comprehensive source, it is primarily used by pharmacists rather than nurses. Nurses might find it less practical for their day-to-day needs as it is detailed and more suited to in-depth drug comparisons.
Choice B rationale
A nurse drug guide is designed specifically for nurses and includes practical information for administering medications, understanding side effects, and nursing considerations. It’s tailored to the needs of nursing practice.
Choice C rationale
A drug package insert provides detailed information about a specific drug, including indications, dosage, and side effects. However, it lacks the breadth of information about multiple drugs and nursing considerations compared to a nurse drug guide.
Choice D rationale
The Physician’s Drug Reference (PDR) is an excellent resource but is more suited for physicians. It provides detailed drug information but may not focus on nursing-specific considerations and practical administration advice.
