When administering a medication that requires peak and trough levels, what is the nurse's best action?

A. Give the medication only when the client requests: Administering medication on the client’s request may not align with the timing needed for accurate peak and trough levels. This approach can compromise therapeutic monitoring and safety. B. Coordinate administration with laboratory timing for accurate peak and trough levels: Peak and trough levels measure the highest and lowest concentrations of a medication in the blood to ensure efficacy and prevent toxicity. Proper coordination of dosing and lab draws is essential for accurate monitoring and safe medication management. C. Administer the medication at any time: Giving the medication without regard to timing can result in inaccurate peak and trough measurements, increasing the risk of underdosing or toxicity. Timing is critical for medications requiring serum level monitoring. D. Ensure the client consumes a high-fat meal with the medication: Food content may affect absorption of some medications, but a high-fat meal is not a universal requirement and does not replace correct timing for peak and trough monitoring. It is not the primary consideration in this scenario.
