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.

Correct Answer is A
Explanation
A. Blocking agents: Antagonist medications block the action of other substances, typically by binding to receptors without activating them, thus preventing other substances from binding.
B. Palliative care medications: These medications are used to relieve symptoms in patients with serious illnesses but do not describe how antagonist medications work.
C. Diagnostic medications: These are used in diagnostic tests and procedures but do not describe the action of antagonists.
D. Synergistic medications: Synergistic medications enhance the effects of each other when used together. This is the opposite of what antagonists do, as antagonists typically inhibit effects.
Correct Answer is D
Explanation
A. "This medication will replace vitamins and minerals that may be lost due to bleeding during surgery." Cefazolin is an antibiotic, not a replacement for vitamins and minerals. This statement is incorrect.
B. "This is a palliative medication to help ease the pain from surgery."Cefazolin is not a palliative medication; it is an antibiotic used to prevent infection, not to relieve pain.
C. "This medication will help the surgeon identify areas of bone destruction due to arthritis." Cefazolin does not aid in the identification of bone destruction. It is an antibiotic, not a diagnostic tool.
D. "This antibiotic is given as a prophylactic to help reduce the risk of infection after surgery."
This statement is correct. Cefazolin is given prophylactically to reduce the risk of postoperative infection.
