Chapter 8: Overview of Genetics and Genomics in Nursing - Nurselytic

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.

Correct Answer: D

Rationale: The nurse must honor the patient's wishes while explaining the potential benefit this information may have for other family members. Breaching confidentiality or suggesting mandatory disclosure by a geneticist is incorrect. Encouraging reflection is secondary to respecting confidentiality.

Correct Answer: A

Rationale: The Genetic Information Nondiscrimination Act (GIN
A), 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.

Correct Answer: B

Rationale: Nurses assess the patient's capacity and ability to give voluntary consent. Language differences prevent the husband from giving informed consent without a translator. Having the wife translate or explaining in simple English does not ensure accurate understanding, and signing without comprehension is unethical.

Correct Answer: C

Rationale: Nurses obtain patient consent to obtain medical records to ensure appropriate information and counseling, including risk interpretation, are provided. Vague responses like â??just in case' or â??due diligence' do not adequately explain the need for medical records.
