The LPN/LVN is aware that the bioavailability of a drug is based on multiple factors. Which factor(s) would be included?
Correct Answer: A,B,E
Rationale: Molecular weight: Drugs with lower molecular weight tend to have higher bioavailability because they can more easily pass through biological membranes. Fat or liquid solubility: Drugs that are fat-soluble can cross cell membranes more easily, affecting their bioavailability. Presence of food: Food in the stomach can either enhance or inhibit drug absorption, depending on the drug's characteristics.
