Discussion Questions


1. How do you interpret the history?
 
2. What is polycystic kidney disease?
 
3. What is the difference between a dialysis shunt and an arteriovenous fistula?
 
4. Why might patients need multiple dialysis access sites? Is this common?
 
5. Given that the patient was using the right arm arteriovenous fistula during dialysis, what can you presume about the other two access sites (i.e., do you think they were functional or not)?
 
6. Why might a arteriovenous fistula bleed?
 
7. How do you interpret the patient’s care plan?
 
8. The amount of bleeding is not specified. How much bleeding do you think there was during the second episode? What’s your evidence?
 
9. Is there a scenario where the overall care plan was appropriate?
 
10. Thinking of the patient as your own, what might you have done differently?
