The nurse is performing an admission assessment on a client. The client states that she has been smoking two packs of cigarettes a day for 20 years. The nurse would chart how many pack years for this client?

  1. 10 pack years
  2. 20 pack years
  3. 30 pack years
  4. 40 pack years
Number 4 is correct.
Rationale: A pack year is one pack of cigarettes smoked daily for one year. This client smokes two packs per day. The calculation is 2 (packs per day) × 20 (years smoking) = 40 pack years. The other calculations are incorrect for this client.
