Answer to Question 1

C
The nurse's response should focus on correcting the patient's misinformation rather than on convincing him to stop smoking. Once a person stops smoking, the body begins to repair the damage. During the first few days, the person will cough more as the cilia begin to clear the airways. Then the coughing subsides, and breathing becomes easier. Even long-time smokers can benefit from smoking cessation. The suggestions that the patient's family will become ill and that oxygen is a fire hazard appear to be scare tactics, which can be seen as coercive, and would not be effective in motivating the patient to stop smoking. Although asking the primary care provider for a prescription may help the patient to stop smoking, it does not address his incorrect belief that it is too late for him to do so.

Answer to Question 2

D
Carbon dioxide (CO2) level provides the primary stimulus to breathe. High CO2 levels stimulate breathing to eliminate the excess CO2 . A secondary, although important, drive to breathe is hypoxemia. Low blood O2 levels stimulate breathing to bring more oxygen into the lungs.
