Practice Question
A nurse is teaching a class about pharmacodynamics. The nurse should include that which of the following medication levels occurs when a medication is at the lowest serum concentration?
Answer Choices:
Correct Answer:
Trough
Rationale:
💊The trough level represents the lowest concentration of a medication in the bloodstream, typically measured immediately before the next dose.
💊Monitoring the trough ensures that the medication remains within the therapeutic range, avoiding subtherapeutic dosing or toxicity.
💊It helps clinicians adjust dosage intervals to maintain steady-state levels for optimal therapeutic effects.
💊Drugs with a narrow therapeutic index (e.g., vancomycin, digoxin) require regular trough monitoring to ensure patient safety.
💊The trough reflects the balance between drug elimination and administration frequency.
