Chapter 8 : Overview of Genetics and Genomics in Nursing Questions
Question 1 of 5
This nurse has consequently completed the first step in what process?
Correct Answer: A
Rationale: Nursing assessment of the patient's health includes obtaining and recording family history information in the form of a pedigree. This is a first step in establishing the pattern of inheritance. It does not directly answer questions or influence genetic outcomes.
Question 2 of 5
What is this foundational genetic test?
Correct Answer: B
Rationale: The family history is considered the first genetic test. It is expected that all nurses will know how to use this genetic tool to assess potential genetic risks and patterns of inheritance.
Question 3 of 5
What knowledge would influence your nursing considerations for genetic testing?
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.
Question 4 of 5
For what health problem would this couple be genetically screened?
Correct Answer: D
Rationale: People of Ashkenazi Jewish descent are screened for conditions such as Tay-Sachs disease and Canavan disease due to higher prevalence in this population. The other conditions are not specifically associated with this group.
Question 5 of 5
What would the nurse know about these two diseases?
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.
