Question 4

Which route of administration provides the fastest onset of drug action in emergency situations?

Accepted Answer

Intravenous (IV)

Answer

Intravenous administration delivers drugs directly into the bloodstream, providing immediate bioavailability and the fastest onset of action.

Question 5

What does the term 'half-life' of a drug refer to in pharmacokinetics?

Accepted Answer

Time for 50% of the drug to be eliminated from the body

Answer

Half-life (t½) is the time required for plasma concentration of a drug to decrease by 50%, which determines dosing intervals and time to steady state.
