The nurse is caring for a client admitted with pneumonia. The patient has a history of smoking 10 cigarettes per day for 30 years. What is the pack year amount? Use numbers only in your answer. No letters.
The Correct Answer is ["15"]
The pack-year amount for a patient who has smoked 10 cigarettes per day for 30 years is calculated as follows: one pack-year is equivalent to smoking 20 cigarettes, which is one pack, every day for one year. Therefore, 10 cigarettes per day is half a pack, and over 30 years, this equates to 15 pack-years (0.5 pack/day * 30 years = 15 pack-years).
