- B. The timing of the last dose of medication relative to when blood was drawn
- C. The possibility of a drug-laboratory test interaction
- D. A change in the body's responses or actions related to the drug
Correct Answer: C
Rationale: The body works through a series of chemical reactions. Because of this, administration of a particular drug may alter results of tests that are done on various chemical levels or reactions as part of a diagnostic study. This drug-laboratory test interaction is caused by the drug being given and not necessarily by a change in the body's responses or actions. The patient's emotional response or timing of the last dose is not important in drug-laboratory interactions.
