Certified Pediatric Hematology Oncology Nurse (CPHON) Practice Exam

Diamond Blackfan Anemia (DBA) is a rare form of macrocytic anemia that typically presents in early childhood and is characterized by a failure of the bone marrow to produce red blood cells. It is important to note that DBA can also be associated with a range of physical anomalies, and one of the more recognized features is the presence of craniofacial dysmorphisms, including a snub nose.

The characteristic "snub nose" often refers to a nose that has a flat, broad appearance, which can be a notable physical feature in some children with DBA. This feature can stem from the underlying genetic and developmental abnormalities associated with the disorder. Furthermore, snub nose may also appear in other genetic conditions, reinforcing its association with certain congenital syndromes.

Understanding the unique physical features associated with DBA can provide insights into the condition that go beyond just hematological implications, helping nurses and healthcare providers to recognize and manage the complexities presented by affected children more effectively.
