Bess, a 21-year-old medical laboratory science student in her last year of training, is completing her morning phlebotomy rounds. Her final patient is a 16-year-old girl diagnosed with type 1 diabetes mellitus. The order is for a fasting blood sugar and a CBC, so Bess collects samples via venipuncture. After performing the venipuncture, Bess cleans up the equipment and trash from the patient’s bed. In doing so, she pokes a gloved finger with the used needle because she failed to engage the safety cover correctly. Even though she is distraught, Bess keeps herself composed and exits the patient’s room. Bess immediately goes and washes her hands with soap and warm water and then heads back to the laboratory.
What is the first thing Bess should do?
a. Go to break; coffee is in order after this ordeal.
b. Inform her supervisor.
c. Go home sick; she cannot effectively work the rest of the day.
d. She was wearing gloves, so it is not a major concern.
b. Inform her supervisor.
