A patient states that she smoked one-half pack of cigarettes for 16 years, but prior to that smoked two packs per day for 23 years. What is her pack-year history?
  1. 58
  2. 54
  3. 26
  4. None of the above
Explanation
Answer: B - The patient’s pack-year history is 54.

Pack-year history is calculated by multiplying the pack quantity by the number of years of smoking. In this case, a combination of the two scenarios is one-half pack x 16 years = 8, and 2 packs x 23 years = 46.
