NURS 3100 Exam 1 Practice

Which of the following describes the principles about how medication dosing schedules are determined?

1. Dosing may be set for the convenience of patient and nurse.

2. Hospitals have routine dosing intervals so that all parties receive medications at the same time each day.

3. Physical and biological characteristics of a drug may determine dosing schedule.

4. Specific times may improve effectiveness and decrease risk for adverse effects.

The correct answer is: Physical and biological characteristics of a drug may determine dosing schedule.

The correct answer is C. Physical and biological characteristics of a drug may determine dosing schedule. This statement reflects the key principle that medication dosing schedules are often determined based on factors such as the drug's pharmacokinetics (how the body processes the drug), pharmacodynamics (how the drug affects the body), half-life, and therapeutic index. These characteristics influence how frequently a medication needs to be administered to maintain effective levels in the body and achieve the desired therapeutic effect. Options A, B, and D do not accurately describe the primary principles behind how medication dosing schedules are determined. Option A focuses on the convenience of the patient and nurse, which may be a consideration but is not the primary factor in determining dosing schedules. Option B discusses routine dosing intervals in hospitals, but these are more about operational efficiency rather than being the primary factor influencing dosing schedules. Option D mentions the importance of specific times for medication administration but does not encompass the broad range of physical and biological characteristics that can determine dosing schedules.
