Chapter 8 : Overview of Genetics and Genomics in Nursing Questions
Question 1 of 5
What could the nurse do to disseminate information about screening to more individuals?
Correct Answer: A
Rationale: The advantage of a health fair is that it will provide information on all age-related diseases and the prevention of disease, including those with genetic components like colon cancer. Referring all employees over 50 to a gastroenterologist is impractical, and a website or brochures may not reach as many people effectively as a health fair.
Question 2 of 5
Which of the following is the most important factor documented in the patients genetic history?
Correct Answer: A
Rationale: A well-documented family history is a tool used by the health care team to make a diagnosis, identify teaching strategies, and establish a pattern of inheritance. The family history should include at least three generations, as well as information about the current and past health status of all family members, including the age of onset of any illnesses and cause of death and age at death. Medications and immunizations are part of the general health history, not specifically the genetic history.
Question 3 of 5
What should the nurse practitioner tell them about cystic fibrosis?
Correct Answer: D
Rationale: Cystic fibrosis is autosomal recessive. People who are related have more genes in common than those who are unrelated, thus increasing their chance for having children with autosomal recessive conditions like cystic fibrosis if both are carriers. It is not autosomal dominant, mitochondrial, or X-linked.
Question 4 of 5
What sign should the nurse instruct the woman to look for in the new baby?
Correct Answer: C
Rationale: Physical assessment may provide clues that a particular genetic condition is present. For neurofibromatosis type 1, skin findings like caf-au-lait spots are a key indicator. Increased urination might suggest diabetes, projectile vomiting could indicate pyloric stenosis, and xanthomas are associated with hyperlipidemia, not neurofibromatosis.
Question 5 of 5
What should the nurse do?
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 by contacting siblings or their physicians is unethical. Involving a geneticist may be helpful, but the primary action is to respect the patient's confidentiality while encouraging disclosure.
