Illustrating the Addition of a Genetics Module to a Diagnostics Class for Advanced Practice Registered Nurses

Diagnostics for the Advanced Practice Registered Nurse is a course that prepares the graduate nursing student for the use, interpretation, and application of laboratory and diagnostic techniques and procedures. Genetic testing is currently being used to help patients identify if they are at increased risk of a disease and related health problems as well as providing important information on the appropriate type of treatment and response to treatments for certain diseases. Genetic testing is emerging as a critical component in the diagnostic work-up of many patients. However curriculum content that includes foundational information on genetics and genetic testing components has often been lacking from Advanced Practice Registered Nurse Diagnostic coursework. Therefore the co-course directors consulted with a genetics content expert to provide guidance in adding a module to this course that included genetics and genetic testing.

The module objectives center around seeking to provide guidance to help students understand genetics as it relates to the clinical arena. Specific attention is given to understanding genetic terminology. A basic review of genetic concepts is provided along with an introduction to the process of genetic counseling. Significant attention is paid to the description of different types of genetic testing and their application. Emphasis is placed on how to appropriately interpret genetic testing reports. To assist in the application of this knowledge, students are given a patient scenario and asked to select an appropriate genetic test.

The content is structured around the point in the lifespan where genetic testing is commonly used. These three points are: 1) prenatal/newborn, 2) pediatric, and 3) adult. A handout is provided on the definition of formats of clinical tests that details various tests that are used. The NIH pamphlet on genetic testing is also referenced. Delivering an evidence-based practice diagnostic work-up is emphasized as information is provided on the levels of evidence of genetic testing and family history. Upon completion of this genetics module, graduate nursing students should have an introductory framework that they can utilize when they are working with their patients in choosing appropriate genetic testing.
