Question 5 of 5
The LPN/LVN is aware of the drug cycle that begins with the administration of a drug. Which factor(s) would influence the amount of time needed to complete the drug cycle of a drug?
Correct Answer: A,C,D,E
Rationale: Age affects drug metabolism and excretion. Older adults often have slower metabolism and impaired organ function, which can prolong the drug cycle. The brand or generic status of a drug does not typically influence the drug cycle. The route of administration significantly influences the onset, intensity, and duration of a drug's action. The health of organs like the liver and kidneys is crucial because these organs are involved in the metabolism and excretion of drugs.
