When the nurse tries to explain alcoholism, she admits there is no one theory. The nurse is able to state that there may be a genetic tendency, because sons of alcoholic fathers have this risk of developing alcoholism:

A. 20% to 25%: While a moderate estimate, studies show higher genetic risk among children of alcoholics, particularly sons. B. 30% to 50%: Research indicates that sons of alcoholic fathers have a significantly higher risk of developing alcoholism due to both genetic and environmental factors. C. 0% to 5%: This underestimates the risk and does not reflect established genetic research findings. D. 10% to 15%: Still underestimates the actual genetic risk observed in studies of familial alcoholism.
