Answer: C. By discarding this unlabeled syringe, the nurse eliminates the risk of giving the wrong drug or solution to the patient. Never administer unlabeled syringes or solutions. If you do, there's no way to be certain that you're giving the right drug. Even if the other nurse confirms the syringe's contents, it's possible that the syringe became mixed up with another one at the bedside. It's best to be safe—draw up and label a new syringe with D₁₀W to administer to the patient.
