This is a PRN position. How do you keep track of clinic protocols and patients when you are not there every day?

A patient calls to say they have had black, tarry stools since yesterday. What do you ask and what do you advise?

A biopsy result comes back abnormal and the provider has not reviewed it yet. What do you do?

About the work

Walk me through how you would explain colonoscopy prep to a patient who has never had one.

What they are checking: Whether they can teach a confusing prep clearly enough that the procedure does not get canceled.

How do you manage patients on blood thinners or diabetes medications before a procedure?

What they are checking: Whether they know holding instructions come from the provider and that missed steps cause harm or cancellations.

How do you teach a patient with Crohn's disease or ulcerative colitis about managing a new medication?

What they are checking: Whether they cover side effects, infection risk and lab monitoring in plain language with teach-back.

How do you make sure your documentation is accurate and complete at both the clinic and system level?
