Which of the following is not likely to cause a medication error?

Checking the medication label with the Medication Administration Record (MAR) is a crucial practice to ensure that the right medication is being administered to the right patient at the right time and in the right dose. This process serves as a safeguard against potential medication errors by verifying that the medication matches what is prescribed, thus confirming accuracy and reducing the risk of incorrect medication administration.

In contrast, not checking a patient’s medication history, administering medication without consent, and using look-alike drug names all represent scenarios that are more likely to lead to medication errors. Failing to check a patient's medication history can result in overlooking potential drug interactions. Administering medication without consent disregards the patient's autonomy and can lead to legal and ethical issues. Using look-alike drug names can easily confuse healthcare providers and lead to administering the wrong medication. Therefore, verifying the medication label with the MAR is a vital step in preventing medication errors.
