A nursing student asks a nurse what the categories of pharmacokinetics are. What is the nurse's best response?

  1. absorption, distribution, metabolism, excretion

  2. absorption, diffusion, metabolism, excretion

  3. movement, ingestion, distribution, excretion

  4. movement, metabolism, diffusion, absorption

The correct answer is: absorption, distribution, metabolism, excretion

The correct response is A. Absorption, distribution, metabolism, and excretion are the four main categories of pharmacokinetics. Absorption refers to the process of how a drug enters the bloodstream, distribution involves how the drug is transported throughout the body, metabolism relates to how the drug is broken down and transformed in the body, and excretion is the elimination of the drug from the body. Options B, C, and D are incorrect as they do not accurately represent the categories of pharmacokinetics.
