Which factor can contribute to a medication error during administration?

An incorrect dosing device can significantly contribute to a medication error during administration because the device is crucial for accurately measuring and delivering the correct amount of medication to the patient. Each medication requires specific dosing parameters, and using the wrong device can lead to overdoses or underdoses. For example, using a syringe meant for adult dosing instead of one for pediatric dosing could dramatically change the quantity of medication administered.

Ensuring that the right device is used is vital for patient safety and effective treatment outcomes. Other factors, such as patient refusal of therapy or effective communication among healthcare team members, may indeed influence therapy but do not directly cause administration errors related to the dosing of medication. Proper labeling of medications generally aids in reducing errors by providing clarity and preventing confusion, which reinforces the idea that accurate dosing devices are essential to preventing medication errors.
