Explain the concept of half-life for a drug.
Differentiate between half-life and steady state.
Explain the difference between potency and effectiveness of a drug.
Respond to the following scenario:
If a drug has a half-life of six hours, how long will it take for the drug to be eliminated from the body after administration of a single dose? Explain how you arrived at that particular cutoff score for complete elimination. Show your calculations on a timeline or graphs to illustrate the changes from 100 percent of the initial dose to your end point for complete elimination.
