A nurse is administering an oral medication that requires monitoring of peak and trough levels. Which action should the nurse prioritize to ensure therapeutic effectiveness?
Documenting the administration time in the patient's chart.
Administering the medication at the same time each day.
Ensuring the patient swallows the medication with a full glass of water.
Scheduling blood draws to coincide with expected peak and trough times,
The Correct Answer is D
Rationale:
A. Documenting the administration time in the patient's chart: Accurate documentation is essential for legal and safety reasons, but it does not directly ensure the therapeutic effectiveness related to peak and trough monitoring.
B. Administering the medication at the same time each day: Consistent timing helps maintain steady drug levels but does not provide the specific data needed to evaluate peak and trough concentrations for therapeutic monitoring.
C. Ensuring the patient swallows the medication with a full glass of water: While swallowing with water aids in absorption and reduces irritation, it does not directly address the measurement of drug levels to ensure therapeutic effectiveness.
D. Scheduling blood draws to coincide with expected peak and trough times: Monitoring peak and trough levels is critical for drugs with narrow therapeutic ranges. Drawing blood at appropriate times ensures accurate measurement of maximum and minimum serum concentrations, guiding safe and effective dosing.

Correct Answer is D
Explanation
Rationale:
A. Centi-: The prefix "centi-" represents one-hundredth (0.01) of a unit, not one-thousandth.
B. Micro-: "Micro-" represents one-millionth (0.000001) of a unit, which is much smaller than one-thousandth.
C. Deci-: "Deci-" denotes one-tenth (0.1) of a unit, not one-thousandth.
D. Milli-: "Milli-" represents one-thousandth (0.001) of a unit, making it the correct metric prefix for this value, commonly used in milligrams (mg) and milliliters (mL).
Correct Answer is C
Explanation
Rationale:
A. It provides the drug's therapeutic class: The therapeutic class describes the drug’s action or purpose but does not help in tracking specific batches for safety issues.
B. It shows the drug's generic name: The generic name identifies the medication but does not contribute to safety monitoring related to manufacturing or recall events.
C. It allows tracing of the drug for recalls: The lot number uniquely identifies a specific batch of medication. In the event of contamination, manufacturing errors, or recalls, the lot number enables healthcare providers and manufacturers to quickly trace and remove affected drugs, protecting patient safety.
D. It indicates the drug's dosage strength: Dosage strength informs proper administration but does not allow for tracing the medication in safety events or recalls.
