ATI Pharmacology Exam 1 | Nurselytic

Correct Answer: C

Rationale: The correct answer is C: Subjects with the disease the drug will treat. In a drug trial, it is crucial to test the drug's efficacy and safety in the target population, i.e., individuals with the specific disease the drug is intended to treat. By including subjects with the disease, researchers can assess how the drug performs in real-world conditions and whether it effectively treats the condition. This phase helps determine the drug's therapeutic benefits and potential side effects in the intended patient population. It is essential to exclude healthy individuals (choice
D) from this phase, as they do not represent the target patient group. Including healthy and ill subjects (choice
A) or subjects with other diseases (choice
B) may confound the results and make it difficult to assess the drug's specific effects on the target disease.
