The school nurse is presenting a class on smoking cessation at the local high school. A participant in the class asks the nurse about the risk of lung cancer in those who smoke
What statement by the nurse is correct related to risk for cancer in smokers?
A) "Risk is determined by the pack-year, the age of initiation of smoking, the depth of inhalation, and the tar and nicotine levels in the cigarettes smoked."
B) "The risk for cancer never decreases, so you will need annual chest x-rays."
C) "The risk is determined by pack-year history and the age you started smoking."
D) "The risk for cancer increases annually and there is nothing you can do about that."
Ans: A
Feedback: Risk is determined by the pack-year history (number of packs of cigarettes used each day, multiplied by the number of years smoked), the age of initiation of smoking, the depth of inhalation, and the tar and nicotine levels in the cigarettes smoked. The younger a person is when he or she starts smoking, the greater the risk of developing lung cancer. Options B and D are incorrect; they give the person asking the question inaccurate information. Option C is incorrect as it is incomplete.
