- A.
Are most commonly present in newborn infants.
- B.
Always become worse as a person ages.
- C.
Are directly attributable to a mutation in the genes.
- D.
are always diagnosed after others have determined that a genetic condition is present in the family.
Correct Answer
C. Are directly attributable to a mutation in the genes.Explanation
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.Rate this question:

Families that have an inherited disorder:
- A.
Are entitled to genetic information about all family members
- B.
are generally well-informed about the genetic aspects of the condition.
- C.
May not wish to discuss genetic information with all family members.
- D.
Share common coping responses to learning about genetic aspects of the condition.
Correct Answer
C. May not wish to discuss genetic information with all family members.Explanation
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.Rate this question:

People with a high need for certainty are more likely to:
- A.
Avoid discussion of genetic information with biological relatives.
- B.
Pursue learning information about a genetic condition.
- C.
Act in accordance with a set of family norms and values.
- D.
Negotiate changes in family roles with key family members.
Correct Answer
B. Pursue learning information about a genetic condition.Explanation
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.Rate this question:

A. are likely to request predictive diagnostic testing.
- B.
B. are likely not to ask for predictive diagnostic testing.
- C.
C. are not at risk for development of Huntington disease themselves.
- D.
d. vary in their desire for predictive testing.
Correct Answer
D. d. vary in their desire for predictive testing.Explanation
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.Rate this question:

Genetic diseases:
- A.
Always refer to diseases caused by biological conditions inherited from one family member to another
- B.
Always refer to diseases caused by environmental factors family members share.
- C.
refer to diseases caused by biological and environmental factors family members share.
- D.
Refer to X-linked disorders.
Correct Answer
C. refer to diseases caused by biological and environmental factors family members share.Explanation
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.Rate this question:

When considering genetic diseases, a key ethical consideration is the concept of:
- A.
Confidentiality
- B.
Grief
- C.
Caring.
- D.
caregiving.
Correct Answer
A. ConfidentialityExplanation
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.Rate this question:

Genes control:
- A.
All major organs of the body.
- B.
All personality characteristics of an individual
- C.
An individual’s ability to learn across the life span.
- D.
All functions of the human body at the cellular level.
Correct Answer
D. All functions of the human body at the cellular level.Explanation
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.Rate this question:

If a disease is present in more than one generation, then:
- A.
a genetic disease is present.
- B.
The family should be assessed for environmental risk factors affecting multiple generations.
- C.
the family does not have a genetic disease.
- D.
The family may have a biologically based or environmentally based genetic disease, or a combination of biological and environmental factors affecting the health of family members.
Correct Answer
D. The family may have a biologically based or environmentally based genetic disease, or a combination of biological and environmental factors affecting the health of family members.Explanation
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.Rate this question:

- When a recessive pattern is identified for a genetic disease within a family, this means that:
- A.
25% of the offspring will have the disease.
- B.
The probability of having the disease is 1 in 4.
- C.
50% of offspring will have the disease.
- D.
The probability of having the disease is 1 in 2.
Correct Answer
B. The probability of having the disease is 1 in 4.Explanation
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.Rate this question:
