Which of the following routes would have the fastest onset of action?

  1. Oral

  2. Intravenous

  3. Topical

  4. Inhalation

The correct answer is: Intravenous

The fastest onset of action would be through the intravenous route. This is because the medication is directly injected into the bloodstream, bypassing the digestive system and avoiding any potential delays in absorption. Oral and topical routes may have a slower onset of action as the medication needs to be absorbed through the digestive or skin barrier first. Inhalation may also have a slower onset as the medication needs to be absorbed through the respiratory system before reaching the bloodstream. Therefore, option B is the correct answer for the fastest onset of action.
