A patient wants to know about the possible interactions of the various drugs that he has been prescribed for an illness. The nurse explains that the drugs interact with each other and produce an effect that is greater than the sum of their separate actions. Which of the following reactions is the nurse informing about?

  • A. Additive drug reaction
  • B. Synergistic drug reaction
  • C. Antagonistic drug reaction
  • D. Toxic drug reaction
Correct Answer: B

Rationale: A synergistic drug reaction occurs when drugs interact with each other and produce a sum greater than the sum of their separate actions. An additive drug reaction occurs when the combined effect of two drugs is equal to the sum of each drug given alone. An antagonistic drug reaction occurs when one drug interferes with the action of another, causing neutralization or a decrease in the effect of one drug. Toxic drug reactions are caused when blood concentration levels exceed the therapeutic levels of a drug.

  • A. Pharmacotherapeutics
  • B. Pharmacokinetics
  • C. Pharmacoeconomics
  • D. Pharmacogenomics
Correct Answer: B

Rationale: When administering a drug, the nurse needs to consider the phases of pharmacokinetics so that the drug regimen can be made as effective as possible. Pharmacogenomics is the area of study that includes mapping of the human genome. Pharmacotherapeutics is the branch of pharmacology that deals with the uses of drugs to treat, prevent, and diagnose disease. Pharmacoeconomics includes all costs involved in drug therapy.
