Fhcn- Chapter 7 Genomics And Family Nursing Across Life Span

Genetic disorders can be diagnosed before birth through prenatal testing, such as amniocentesis or chorionic villus sampling. They can also be diagnosed before conception through genetic counseling and carrier screening. Additionally, genetic disorders can be diagnosed during an acute or chronic illness through genetic testing or analysis of symptoms. Therefore, all of the given options are correct as they represent different ways in which genetic disorders can be diagnosed.

Nurses use genetic knowledge in all healthcare settings because genetics plays a role in various aspects of healthcare, including understanding the risk of genetic conditions, providing genetic counseling, administering genetic tests, and incorporating genetic information into treatment plans. Genetic knowledge is relevant and applicable across all areas of healthcare, not just limited to specific specialties or populations.

If a disease is present in more than one generation, it suggests that the disease may be influenced by both genetic and environmental factors. This means that the disease could be biologically based, environmentally based, or a combination of both. Therefore, it cannot be concluded that the family has a genetic disease or that they do not have a genetic disease. Instead, further assessment is needed to determine the specific factors affecting the health of family members.

When considering genetic diseases, confidentiality is a key ethical consideration because it involves respecting and protecting an individual's privacy and sensitive medical information. Genetic diseases can have significant implications for individuals and their families, and maintaining confidentiality ensures that their personal information is not disclosed without their consent. It also helps to prevent discrimination and stigmatization based on genetic conditions. By prioritizing confidentiality, healthcare professionals can build trust with patients and create a safe environment for open communication and effective treatment.

People with a high need for certainty are more likely to pursue learning information about a genetic condition because they have a strong desire to have clear and definite answers. They seek out information to alleviate any uncertainty or ambiguity surrounding the genetic condition, as having knowledge about it provides them with a sense of security and control. This behavior is driven by their need to have a solid understanding of the situation and to minimize any potential risks or unknown factors associated with the genetic condition.

Genetic conditions are directly attributable to a mutation in the genes because genetic conditions are caused by changes or abnormalities in a person's DNA. These mutations can be inherited from parents or can occur spontaneously. The presence of a mutation in the genes is what leads to the development of a genetic condition.

Families that have an inherited disorder may not wish to discuss genetic information with all family members because some individuals may not want to know about their genetic risk or may not be emotionally prepared to handle the information. Additionally, sharing genetic information with all family members may lead to unnecessary anxiety or stress for those who are not directly affected by the disorder. Therefore, it is important to respect the privacy and autonomy of each family member when it comes to discussing genetic information.

Family members of people with Huntington disease may have different attitudes and desires regarding predictive diagnostic testing. Some may be interested in knowing their own risk for developing the disease, while others may choose not to undergo testing. Therefore, the correct answer is that family members vary in their desire for predictive testing.

When a recessive pattern is identified for a genetic disease within a family, it means that the disease is caused by a recessive gene. In order for an individual to have the disease, they must inherit two copies of the recessive gene, one from each parent. Since both parents are carriers of the recessive gene, there is a 1 in 4 chance that any given offspring will inherit two copies and therefore have the disease.

Genes control all functions of the human body at the cellular level. Genes are segments of DNA that contain instructions for building and maintaining the body's cells and tissues. They play a crucial role in regulating various cellular processes such as metabolism, growth, and reproduction. Genes also determine the production of proteins, which are essential for carrying out specific functions within cells. Therefore, genes are responsible for controlling all the intricate and complex functions that occur within the human body at the cellular level.

The correct answer is more frequent mammography studies to detect the first indication of cell changes. This is because regular mammography screenings can help detect breast cancer at an early stage, especially in individuals with a familial pattern of breast cancer. Detecting cell changes early can lead to early intervention and better treatment outcomes.

The human genome refers to the complete set of instructions to make an organism. It includes all the genetic material, such as DNA, that carries the information needed for the development and functioning of a human being. The genome contains all the genes and chromosomes that determine the traits and characteristics of an individual.

Genetic diseases refer to diseases that are caused by both biological and environmental factors that are shared among family members. This means that these diseases can be influenced by both genetic factors inherited from one family member to another, as well as environmental factors that are common within the family. This answer option accurately captures the multifactorial nature of genetic diseases.
