Which of the following describes fixed dosing?

The dose is adjusted by weight The dose is the same for all patients regardless of weight The dose is adjusted by age The dose is adjusted by gender

Correct Answer:

The dose is the same for all patients regardless of weight

Explanation:

Fixed dosing means giving the same amount of a drug to everyone, regardless of body size or other patient characteristics. This approach works when the drug has a wide therapeutic window and predictable behavior across people, so one standard dose provides similar effects and safety for most patients. It simplifies prescribing and reduces dosing errors. Other patterns involve tailoring the amount based on weight, age, or gender, which are used when body size or physiology significantly affects drug exposure or response.
