Question 1 of 5
A nurse is working in a clinical research trial that has a control group and an experimental group but does not know which group is receiving the active drug. Which statement best identifies the research design?
Correct Answer: D
Rationale: The correct answer is D: Double-blind. In a double-blind research design, neither the participants nor the researchers know who is receiving the active drug or the placebo. This helps eliminate bias and ensures the validity of the results.
Choice A (Placebo group) is incorrect because it only refers to the group receiving the placebo, not the overall research design.
Choice B (Experimental drug) is incorrect as it does not specify the blinding aspect.
Choice C (Control group) is incorrect as it does not address the blinding of the study. Double-blind design ensures unbiased results by preventing both participants and researchers from influencing the outcome based on their knowledge of group assignments.
