The nurse should recognize that this patients health status may be the result of what phenomenon?
- A. X-linked inheritance
- B. Autosomal recessive inheritance
- C. Autosomal dominant inheritance
- D. Multifactorial inheritance
Correct Answer: D
Rationale: Many birth defects and common health conditions, such as heart disease, high blood pressure, cancer, osteoarthritis, and diabetes, occur as a result of interactions of multiple gene mutations and environmental influences. Thus, they are called multifactorial or complex conditions. X-linked, autosomal recessive, and autosomal dominant conditions are caused by single gene mutations, not multiple gene interactions.

What sign should the nurse instruct the woman to look for in the new baby?
- A. Increased urination
- B. Projectile vomiting
- C. Caf-au-lait spots
- D. Xanthoma
Correct Answer: C
Rationale: Physical assessment may provide clues that a particular genetic condition is present. For neurofibromatosis type 1, skin findings like caf-au-lait spots are a key indicator. Increased urination might suggest diabetes, projectile vomiting could indicate pyloric stenosis, and xanthomas are associated with hyperlipidemia, not neurofibromatosis.
On what does the nurse explain their chances of developing breast cancer depend?
- A. Sensitivity
- B. Conductivity
- C. Penetrance
- D. Susceptibility
Correct Answer: C
Rationale: A woman who has the BRCA1 hereditary breast cancer gene mutation has a lifetime risk of breast cancer that can be as high as 80%, not 100%. This quality, known as incomplete penetrance, indicates the probability that a given gene will produce disease. Sensitivity, conductivity, and susceptibility are not relevant terms in this context.
What is this foundational genetic test?
- A. The developmental assessment
- B. The family history
- C. The physical assessment
- D. The psychosocial assessment
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.
What is nursings unique contribution to genomic medicine?
- A. Its physical assessment capabilities
- B. Its holistic perspective
- C. Its biopsychologic focus
- D. Its evaluation capabilities
Correct Answer: B
Rationale: The unique contribution of nursing to genomic medicine is its holistic perspective that takes into account each person's intellectual, physical, spiritual, social, cultural, biopsychologic, ethical, and esthetic experiences. This holistic approach is unique compared to other disciplines.
What legislation has as its purpose to protect Americans against improper use of genetic and genomic information?
- A. Genetic Information Nondiscrimination Act
- B. Genetic Confidentiality Agreement
- C. The White Paper on Genetic Testing Results
- D. Genetic Equity Act
Correct Answer: A
Rationale: The Genetic Information Nondiscrimination Act (GINA), signed into law in 2008, protects Americans against improper use of genetic and genomic information in insurance and employment decisions. The other options do not exist.
