1. A nurse is caring for a patient with chronic obstructive
pulmonary disease (COPD) who is experiencing an acute
exacerbation. The nurse notices that the patient's oxygen
saturation is 88% on room air. What is the most appropriate
action for the nurse to take?
a) Administer oxygen via nasal cannula at 2 L/min
b) Administer oxygen via non-rebreather mask at 15 L/min
c) Administer oxygen via simple face mask at 6 L/min
d) *Administer oxygen via venturi mask at 24%*
Rationale: The correct answer is d. A venturi mask delivers
a precise concentration of oxygen and is preferred for
patients with COPD who are at risk of carbon dioxide
retention. A nasal cannula, a non-rebreather mask, and a
simple face mask deliver variable concentrations of oxygen
and may cause oxygen toxicity or hypercapnia in patients
with COPD.
2. A nurse is conducting a health history interview with a
patient who has a history of hypertension, diabetes
mellitus, and hyperlipidemia. The nurse asks the patient
about his medication adherence and lifestyle modifications.
The patient states that he sometimes forgets to take his
medications and that he does not follow a specific diet or
exercise regimen. What is the best response by the nurse?
a) *"It is important to take your medications as prescribed
and to make some changes in your diet and physical
activity to prevent complications from your chronic
conditions."*
b) "You should not skip your medications or eat unhealthyÂ
