Direct DNA sequenc... ing c. Fluorescence in situ hybridization d. Immunohistochemistry Question 2 Answer saved Points out of 1 Flag question Question text Which normal cell characteristic is represented by the production of insulin in the beta cells of the pancreas? Select one: a. Tight regulation of cell division b. Conservation of energy c. Ability to undergo apoptosis on schedule d. Performance of a differentiated function Question 3 Answer saved Points out of 1 Flag question Question text Juliet tells a nurse that she has three aunts (two on her father’s side, ages 42 and 56, and one on her mother’s side, age 62) who were diagnosed with breast cancer. She asks if she should have genetic testing. What should the nurse tell her? Select one: a. “Your family history indicates a high risk and you should definitely have genetic testing.” b. “Because no men in your family are affected, it is not inherited cancer so you don’t need mammograms or any special screening practices.” c. “Because your aunts were older when they got breast cancer, it was probably sporadic and you should just have regular mammograms like everyone else.” d. “Your family history may indicate an increased risk for breast cancer and a genetic counselor could help determine whether you could benefit from genetic testing.” Question 4 Answer saved Points out of 1 Flag question Question text An 85-year-old patient states that she does not perform breast self-exam because there is no history of breast cancer in her family. What is the best response? Select one: a. “Breast cancer can be found more frequently in some families; however, the risk for general, nonfamilial breast cancer increases with age.” b. “Because your breasts are no longer as dense as they were when you were younger, your risk for breast cancer is now decreased.” c. “You are correct. Breast cancer is an inherited type of malignancy and your family history indicates a low risk for you.” d. “Examining your breasts once per year when you have your mammogram is sufficient screening for someone with your history.” Question 5 Answer saved Points out of 1 Flag question Question text Your patient, Maggie, insists that her mother have genetic testing to determine if her breast cancer is connected to a mutation in the BRCA1/2 genes. Maggie is concerned about her own risk for getting breast cancer and that of her children, but Maggie’s mom does not want to be tested. What ethical principle is one of several that must be considered in evaluating this case? Select one: a. Maggie’s “autonomy” b. Maggie’s mother’s “right to know” c. The nurse’s “duty to warn” d. Maggie’s mother’s “right to privacy” Question 6 Not yet answered Points out of 1 Flag question Question text Why is determining the genetic contribution important to assess in stroke patients?

No, a clinical geneticist must be certified as a genetic counselor. d. No, a clinical geneticist is a physician who has completed a fellowship in clinical genetics. Question 8 Not yet answered Points out of 1 Flag question Question text What is the best description of the genetic contribution to onset of autism? Select one: a. Autism spectrum disorders have a much stronger environmental input than genetic input to expression of the phenotype. b. Autism spectrum is caused by a single gene mutation in most, but not all, cases. c. Exposure to a teratogen can be a cause of autism spectrum in many cases. d. Known causes of autism spectrum include copy number variants and chromosomal problems. Question 9 Not yet answered Points out of 1 Flag question Question text Which “schizophrenia fact” is correct? Select one: a. Because the phenotype of schizophrenia is so obvious, diagnosis and inheritance risk are the most easily determined of all the psychiatric disorders. b. When one identical twin is affected with schizophrenia the other most certainly will be affected. c. When schizophrenia has more genetic influence, its onset begins in very early childhood. d. Copy number variants appear to play the most important role in genetic risk for schizophrenia.

Loss of an existing function c. Gain of a new function d. Increased unequal “crossing over” during meiosis I In which body or cell area are most genes in humans located? Select one: a. Mitochondrion b. Cytoplasm c. Plasma Membrane d. Nucleus Question 12 Not yet answered Points out of 1 Flag question Question text Which type of body tissue has the highest risk for cancer development? Select one: a. Bone tissue because its absorption of radiation is cumulative b. Connective tissue that remains functional throughout life c. Any tissue that retains the ability to divide d. Brain tissue because it does not respond well to injury Question 13 Not yet answered Points out of 1 Flag question Question text What is the heritability estimate for schizophrenia in the general population? Select one: a. 60% b. 40% c. 100% d. 80% Question 14 Not yet answered Points out of 1 Flag question Question text Which statement regarding behavioral genetics is accurate? Select one: a. A genetic predisposition toward a specific behavior can be modified by altering environmental influences. b. Genes and gene products have been discovered that directly control behavior. c. The genetic susceptibility or predisposition toward a behavioral disorder requires the trigger of an infectious disease for expression. d. The genotypes and phenotypes of behavioral problems or deviations follow Mendelian autosomal recessive inheritance patterns. Question 15 Not yet answered Points out of 1 Flag question Question text Which statement best describes the role of tumor suppressor genes in cancer development? Select one: a. Tumor suppressor genes control or modify the activity of oncogenes, reducing the risk for cancer development. b. The presence of tumor suppressor genes increases the risk for gene damage by environmental carcinogens. c. Tumor suppressor genes reduce/suppress immune function, increasing the risk for cancer development. d. Tumor suppressor genes are a type of oncogene that is only active in germ line cells and tissues. ---------------------------------------------------------------------------------------------------------------------------- An adult daughter whose mother has bipolar disorder is concerned that she may also have the disorder because she engages in all of the following behaviors.

The focus of their professional education is the study of medicine rather than genetics. b. The typical patients seen by these health-care providers have acute conditions rather than chronic conditions, and thus genetic influence is irrelevant. c.

Most of today’s physicians and surgeons were educated before completion of the human genome research project. A patient is 34 years old and concerned about possibly being a carrier for HNPCC because his father died of colon cancer at 39, his father’s sister died of colon cancer at age 41, and his brother (aged 37) now has colon cancer. The brother’s testing is negative for all the known mutations associated with inherited forms of colon cancer. How should this patient be counseled about his risk for colon cancer? Select one: a. Explain that testing for him would be of no benefit because of the current test limitations but that his family history does place him a high risk. b. Explain that he could benefit from testing even though his brother is negative for these mutations because reduced penetrance might account for his negative status. c. Explain that his risk is not related to his brother’s diagnosis because he did not inherit any genes from him but that since his father is a first-degree relative, testing should be considered. d. Explain that because the brother with cancer is negative for these gene mutations, this cancer is most likely sporadic and his risk is the same as general population risk. Which condition or behavior suggests attention deficit hyperactivity disorder (ADHD)? Select one: a. An 8-year-old who can hop on one foot but cannot ride a bicycle without training wheels. b. A 10-year-old who prefers to play basketball rather than chess. c. A 5-year-old who does not want to go to bed at 8:00 p.m. and begs to be allowed to stay up later. d. A 9-year-old who does not focus on a favorite story or game for longer than 3 minutes. Sometimes health-care providers with information about family members’ genetic risk are confronted by conflicting ethical principles.
