What must sterile team members do prior to accepting medications onto the sterile field?

Prior to accepting medications onto the sterile field, sterile team members must verify the name and dosage of the medication. This step is crucial because it ensures that the right medication is given in the correct dosage, which is vital for patient safety and the success of the surgical procedure. Confirming the name prevents the potential for errors associated with similar-sounding or similar-looking medications, while ensuring the dosage is appropriate helps avoid dosing errors that could lead to adverse outcomes.

The other options, while they may be relevant in different contexts, do not address the primary concerns of ensuring safe medication administration on the sterile field. Reviewing the expiration date is important for medication safety, but it does not address potential errors that could arise from administering the wrong medication or incorrect dosage. Checking the size of the container and confirming with the surgeon may be necessary in some scenarios, but they do not directly impact the immediate safety of the medication being administered. Thus, verifying the name and dosage is the most critical step that must be taken by sterile team members.
