1. A 35-year-old pregnant patient expresses concern to the nurse about the potential for cystic fibrosis in her children.What is the most appropriate nursing intervention? 1 Tell her that she needs to discuss the issue with a genetic counselor. 2 Inform her about the at-home genetic test kits available in the market. 3 Explain to her how to take the sample and mail it back to the laboratory. 4 Educate her on how to read and interpret the results of the genetic test.: Answer The nurse should tell the patient to discuss the issue of genetic testing with her health care provider or a genetic counselor. Without appropriate counseling, there are chances that the patient could be misled or misinformed by the results of unproven or invalid tests, resulting in wrong decisions.The nurse should not encourage self-directed testing.The sample may not be properly collected when self-testing at home. A health care provider should be consulted so that important decisions can be made based on accurate information. TextReference - p. 197 2. A nurse is studying the genetic test report of a patient.The test reveals the presence of a mutated BRCA1 gene. How should the nurse explain the test result to the patient? 1 "You have breast cancer. You may need to get one or both breastsremoved." 2 "You are at risk of developing breast cancer.You should seek advice from an oncologist." 3 "You do not have breast cancer but your daughters may have breast cancer in the future." 4 "Your husband needs to be tested for the presence of BRCA1 gene.": Answer The presence of the BRCA1 and/or BRCA2 gene significantly increases an individuals' risk of developing breast cancer.The nurse should suggest the patient seek advice from an oncologist.The presence of the BRCA1 gene does not confirm the presence of breast cancer. The test result does not confirm the absence of the cancer, nor does it suggest that the patient's daughters may have breast cancer. Asking the patient to get her husband tested for the presence of the BRCA1 gene is not an appropriate response to this test result. TextReference - p. 194 3.
