What knowledge would influence your nursing considerations for genetic testing?
- A. What genetic tests predict the patients husbands risk of Alzheimers disease
- B. What actions the geneticist has recommended for treating the disease
- C. The genetic bases of adult-onset conditions such as Alzheimers disease
- D. Whether any of the patients peers have Alzheimers disease
Correct Answer: C
Rationale: Knowledge of adult-onset conditions and their genetic bases (i.e., mendelian versus multifactorial conditions) influences the nursing considerations for genetic testing and health promotion. The husband's risk or peers' conditions are not relevant, and geneticists do not typically make treatment recommendations.

After the couple receives the results of genetic testing, the nurse should prioritize which of the following?
- A. Secondary illness prevention
- B. Psychosocial support
- C. Gene therapy
- D. Assessing adherence to treatment
Correct Answer: B
Rationale: Following the communication of the findings of genetic testing, it is important that patients receive thoughtful and thorough support to address emotional and psychological impacts. Secondary prevention, gene therapy, or treatment adherence may not be immediately relevant.
Which of the following actions is most consistent with this role?
- A. Planning treatment modalities for diseases that have patterns of inheritance
- B. Processing tissue samples to obtain genetic information
- C. Choosing options for patients after genetic testing has been completed
- D. Informing patients about the ethics of genetics and genomic concepts
Correct Answer: D
Rationale: Nurses inform patients about genetics and genomic concepts, including ethical considerations, and value the privacy and confidentiality of such information. Nurses do not typically plan medical treatments, process tissue samples, or make choices for patients.
For what health problem would a patient of African American heritage most likely have genetic carrier testing?
- A. Meckels diverticulum
- B. Sickle cell anemia
- C. Huntington disease
- D. Rubella
Correct Answer: B
Rationale: Assessing ancestry and ethnicity is important to help identify individuals who could benefit from genetic testing for carrier identification, such as African Americans routinely offered testing for sickle cell anemia. The other conditions are not specifically associated with African American heritage.
What would the nurse know about these two diseases?
- A. They are multifactorial.
- B. They are direct result of the patients lifestyle.
- C. They are caused by a single gene.
- D. They do not have a genetic basis.
Correct Answer: A
Rationale: Genomic or multifactorial influences involve interactions among several genes and between genes and the environment, as well as the individual's lifestyle. Heart disease and osteoarthritis are multifactorial, not caused by a single gene or solely lifestyle, and they do have a genetic basis.
Which of the following is the most important factor documented in the patients genetic history?
- A. Three generations of information about the family
- B. Current medications taken
- C. Health problems present in the womans children
- D. Immunizations received for the past three generations
Correct Answer: A
Rationale: A well-documented family history is a tool used by the health care team to make a diagnosis, identify teaching strategies, and establish a pattern of inheritance. The family history should include at least three generations, as well as information about the current and past health status of all family members, including the age of onset of any illnesses and cause of death and age at death. Medications and immunizations are part of the general health history, not specifically the genetic history.
