JKateri Trelles RN, BSN, CPN, CPHON Kateri Trelles RN, BSN, CPN, CPHON

My name is Kateri Trelles and I have been a registered nurse for almost six years now. I currently work at Nicklaus Children’s hospital on the inpatient Hematology/Oncology/BMT unit. I am also board certified as a Certified Pediatric Nurse (CPN) as well as a Certified Pediatric Hematology Oncology Nurse (CPHON). Prior to working with children, I worked two years with the adult population. I will admit to being skeptical about working with children at first; never in a million years did I imagine myself as a pediatric oncology nurse, but I can honestly say that I love what I do. I became a nurse because I wanted to help people and I am fulfilled knowing that I somehow, even through the simplest gestures, have made a difference in the lives of these kids and their families!

​Working with children with neuroblastoma, like Daniella, is very difficult as the treatment for this diagnosis is very long and intense. Depending on the stage upon diagnosis, patients can expect to undergo surgery, radiation, high dose myeloablative chemotherapy, bone marrow transplant, as well as immunotherapy. It is hard for parents and families to see the light at the end of the tunnel with a seemingly endless journey ahead of them. As nurses we play a vital role throughout the treatment process. We are at the forefront of care that consists of administering chemotherapy agents, managing side effects, educating families on what to expect, as well as providing emotion support. And let’s not forget the nurses’ role as entertainer. It’s not easy keeping a toddler happy while being confined to a tiny bone marrow transplant room for weeks or even months at a time. This calls for some creativity. I remember having Daniella do my makeup in between medications, as well as singing and dancing along to Taylor Swift! But on a serious note, what really amazes me about Daniella and children like her is their strength and resilience. Along with witnessing that strength and resilience, I witnessed the most amazing love between a mother and her child. An unconditional love in which a parent is willing to do whatever it takes to save their child and advocate for their best interest. Being a part of Daniella’s care and seeing how far she has come is why I am able to continue doing what I do.
