Which of the following demonstrates an acceptably identified patient for sample collection and transfusion?

The identification of a patient for sample collection and transfusion is critical in preventing errors and ensuring patient safety. A handwritten band with the patient’s name and ID number meets the necessary criteria for acceptably identifying a patient. The presence of both the name and an identification number reduces the risk of misidentification and allows for accurate matching of blood components with the right patient. This is in line with protocols that emphasize accurate and reliable patient identification prior to any procedures, particularly those involving transfusion.

The other scenarios presented do not provide the same level of assurance. For instance, a taped hospital band to the patient’s bed may not accompany the patient throughout their care, leading to potential misidentification during sample collection or transfusion if the patient changes locations. An unbanded patient, even if responsive, poses a significant risk as there's no formal identification method in place. Lastly, a chart with an unattached armband lacks the physical tie to the patient, making it insufficient for accurate identification. Thus, a handwritten band that clearly indicates the patient's name and identification number is the most reliable and acceptable method for identifying a patient in these scenarios.
