Question

3 multiple choice 1 point methamphetamine can also be taken orally as a pill. which of the following statements is not true of methamphetamine taken orally? the time it takes methamphetamine to reach the systemic circulation is much shorter than if administered intravenously. some methamphetamine can be removed from the body without entering the systemic circulation. less methamphetamine reaches the systemic circulation than if administered intravenously. the bioavailability of methamphetamine depends on the chemical properties of the drug.

Explanation:

• Intravenous (IV) administration delivers a drug directly into the bloodstream, so it reaches systemic circulation almost immediately. Oral administration requires the drug to be absorbed through the gastrointestinal tract, which takes more time. So the statement "The time it takes methamphetamine to reach the systemic circulation is much shorter than if administered intravenously" is not true.
• For the other options: Some drug can be eliminated (e.g., through first - pass metabolism) without entering systemic circulation when taken orally, so the second option is true. Oral administration has a lower bioavailability (less drug reaches systemic circulation) compared to IV, so the third option is true. Bioavailability of a drug (including methamphetamine) depends on its chemical properties (like solubility, permeability) when taken orally, so the fourth option is true.

Answer:

A. The time it takes methamphetamine to reach the systemic circulation is much shorter than if administered intravenously
