Question

21. Scientist have found a link between the risk of one type of stroke and the presence of a specific gene variation.People inheriting two copies of this gene variation have approximately twice the risk of having a stroke compared toindividuals without this variation. Which of the following best explains the importance of this to the public health?A. The discovery may lead to an increase in strokes by identifying the major causes of strokes in healthy individuals.B. The discovery may identify individuals who have a greater risk of stroke and need medical treatment or behavioralchanges.C. The discovery may limit the treatment options for individuals having a stroke and prevent these individuals fromreturning to good health.D. The discovery may cause individuals with other risk factors to disregard any lifestyle changes because their stroke riskis controlled by heredity.

Answer 1

The discovery of the presence of a specific genes variation to people who inherited such genes may be helpful in identifying who are in great risk of stroke. Medical interventions as well as behavioral changes can be undertaken to prevent stroke. If the population that are in great risk are already identified, proper intervention can be implemented. Lifestyle changes can be exercise.

Stroke cases can be reduced by such discovery. Treatment can be provided to identified high risk populationm
