Which groups are explicitly included under Special Populations in Phase IV guidelines?

• A. Investigations in children
• B. Investigations in nursing women
• C. Investigations in pregnant women
• D. Investigations in pregnant women, nursing women, and children

Answer: (D)

Special populations in Phase IV guidelines refer to groups with unique safety and ethical considerations that require careful study design and monitoring. In Phase IV, there is explicit emphasis on including pregnant women, nursing (breastfeeding) women, and children as groups needing special attention. Because each of these groups can experience different pharmacokinetics, safety profiles, and ethical considerations, the guidelines address them together as the set of populations requiring heightened safeguards. Therefore, the option listing all three groups is the best answer. Choosing only one group misses the others that are also explicitly included.
