Who is this Document for ?

This material is ideal for nursing students and qualified nurses preparing for the ANCC Psychiatric-Mental Health Nurse Practitioner (PMHNP) certification exam.

Tutoring staff and educators may also utilise these structured questions to assess student competency in psychiatric genetics.

What you will learn ?
⬤Differentiate between autosomal dominant conditions (e.g., Marfan syndrome) and recessive disorders by analysing multi-generational inheritance patterns and offspring risk percentages.
⬤Identify X-linked genetic disorders, such as fragile X syndrome and color blindness, and explain their specific chromosomal origin on the X chromosome.
⬤Interpret family history tools including pedigrees and genograms to determine likelihoods of genetic disorder transmission within a family unit.
⬤Define the structural components of DNA, specifically how adenine pairs with thymine and guanine pairs with cytosine within the double-helix structure.
⬤Describe the role of genes in directing protein production and distinguish between genotype contributions and observable phenotypic characteristics.
⬤Outline the primary responsibilities of a genetic counselor, focusing on providing information and support to individuals concerned about illness with a genetic basis.
