This situational-based question is asked to see that you are aware when there is a mistake in a patient's drug dosage and how you respond. The interviewers want to hear that you do not let an error like this go unnoticed and will call the physician to clarify the order. You could harm or kill the patient if you fail to contact the physician and give 10 mg instead of 1 mg. On the other hand, if you give 1 mg without calling the physician first, you are going against the doctor's orders. Let the interviewers know how you would handle this situation, using a past example in your response if you have one.
