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?
Placebo group
Experimental drug
Control group
Double-blind
The Correct Answer is D
A. Placebo group: A placebo group refers to participants receiving an inactive substance or placebo, not the research design itself.
B. Experimental drug: The term "experimental drug" refers to the drug being tested, not the design of the study.
C. Control group: The control group receives the placebo or standard treatment for comparison, but this term does not describe the study design.
D. Double-blind: A double-blind study is one in which neither the participants nor the researchers know who is receiving the active drug or placebo. This is the correct term for the described scenario.

Explanation
A. Complete blood count (CBC): A CBC is a standard laboratory test to evaluate overall health and detect a wide range of disorders, including infection or anemia. It is not contraindicated and may be necessary for comprehensive patient care.
B. Placement on a cardiac monitor: Cardiac monitoring is appropriate in cases of overdose as many substances can affect the heart. It helps in early detection of any arrhythmias or other cardiac complications.
