A peak and trough level was obtained from a client receiving an aminoglycoside IV every 8 hours. Which finding presents the highest risk for the client and should be reported immediately to the healthcare provider?

A) A decreased peak and trough level may indicate subtherapeutic levels of the medication but do not pose an immediate risk to the client. Adjustments to the dosing regimen may be needed, but this finding does not require immediate action. B) A decreased trough level alone may suggest a need for dosage adjustment but does not present an immediate risk to the client. It is important to monitor therapeutic drug levels, but this finding does not require immediate reporting to the healthcare provider. C) An increased peak and trough level indicates potential toxicity of the medication. Increased peak levels can lead to nephrotoxicity, while increased trough levels can lead to ototoxicity. Both conditions are serious and require immediate action to prevent harm to the client. The nurse should report this finding immediately to the healthcare provider for further evaluation and possible adjustment of the medication regimen. D) A decreased peak level alone may indicate subtherapeutic levels of the medication, but it does not pose an immediate risk to the client. Adjustments to the dosing regimen may be needed, but this finding does not require immediate action.
