Some people like to play a game that constructs a sequence of chemical elements where each element in the sequence begins with the last letter of its predecessor. For example,….
create a family pedigree for Sarah based on the family information she has provided, What does the pedigree reveal, and what nursing actions would you plan for Sarah?
Recall 17·year-old Sarah from the chapter opening scenario. While at the sports clinic for a routine physical, she questions the nurse about the likelihood that she will acquire Hunting10n disease. Huntington disease is a progressive disorder of motor, cognitive, and psychiatric disturbances.

Sarah’s mother, Diane, is of western European Caucasian de_ scent, Sarah’s knowledge about her father is limited. She knows that he is a third-generation Filipino American but has no medical information on him or his extended family
Sarah’s grandmother on her mother’s side has three sisters and two brothers. The two brothers died of myocardial infarctions at the ages of 37 and 55 years, respectively. Sarah’s maternal grandfather had no brothers but two sisters. Her maternal grandfather died at age 62 years of Huntington disease. The sisters are alive and well and have no medical problems.
Diane has two brothers and two sisters. She is the youngest of the siblings. Her oldest brother, Ken, was diagnosed 10 years ago with Huntington disease at age 41 years.

3. create a family pedigree for Sarah based on the family information she has provided, What does the pedigree reveal, and what nursing actions would you plan for Sarah?
4. Should Sarah be tested at this time? Give a rationale for your answer.
