"I made a mistake early in my career as a Medical Assistant when I inadvertently wrote a patient's blood pressure down as 182/70 instead of 128/70. When the physician saw the chart, they ordered a referral to a cardiologist for further evaluation. I thought that was odd since the patient had normal vital signs and was not complaining of chest pain. I asked why the physician ordered a referral, and they said because the patient's blood pressure was so high. I was confused as to why 128/70 was high, so I looked at the chart again. I realized my mistake and immediately told the physician that I had transposed the numbers. They had me retake the patient's blood pressure, which was within normal limits. The physician laughed it off and told me to be more careful in the future."
