Which blood level is assessed to determine the amount of circulating medication in a patient?.
Trough.
Drug.
Peak.
Therapeutic.
The Correct Answer is C
Choice A rationale:
Trough levels are the lowest concentration in the patient’s bloodstream, hence they are not the best indicator of the amount of circulating medication.
Choice B rationale:
The term ‘Drug’ is too general and does not specifically refer to the amount of medication in the patient’s bloodstream.
Choice C rationale:
Peak levels are the highest concentration of a drug in the patient’s bloodstream after administration. This is when the amount of the medication in the body is likely to be highest.
Choice D rationale:
Therapeutic levels refer to the range in which a drug is expected to be effective without causing any serious problems to the patient. It does not directly indicate the amount of circulating medication.
