ATI - Oxygen Therapy Exam Questions and Answers Fully Solved Latest 2025
Hypercapnia - Answers increased levels of arterial carbon dioxide
Hypoxemia - Answers decreased levels of arterial oxygen saturation
A 57-year-old client with a 30-pack-year smoking history has recently received confirmation of a possible
malignant tumor in the lower lobe of his right lung. He is scheduled for a tumor resection and a lower-
lobe lobectomy in the morning. This client was also diagnosed a year ago with mild chronic bronchitis,
but has never used oxygen therapy. (Lifetime smoking exposure is expressed in pack years. With 20
cigarettes in a pack, multiply the number of packs smoked per day by the number of years of smoking to
determine the pack year. This client smoked one pack a day for 30 years, hence his 30 pack-year
history.)
