Oxygen Therapy NCLEX Questions Questions
Question 1 of 5
The nurse monitors a patient in the emergency department after chest tube placement for a hemopneumothorax. The nurse is most concerned if which assessment finding is observed?
Correct Answer: A
Rationale: A large air leak suggests a persistent pneumothorax or tube malfunction, requiring urgent intervention.
Question 2 of 5
A patient hospitalized with chronic obstructive pulmonary disease (COPD) is being discharged home on O₂ therapy. Which instruction should the nurse include in the discharge teaching?
Correct Answer: C
Rationale: O₂ therapy improves survival and quality of life in COPD; other options are incorrect or outdated.
Question 3 of 5
The clinic nurse makes a follow-up telephone call to a patient with asthma. The patient reports having a baseline peak flow reading of 600 L/min, and the current peak flow is 420 L/min. Which action should the nurse take first?
Correct Answer: B
Rationale: 420 L/min (70% of baseline) is in the yellow zone, warranting albuterol use first.
Question 4 of 5
Which abnormal value requires immediate intervention to improve oxygenation?
Correct Answer: D
Rationale: All the values are abnormal, but the low PaO2 indicates that the patient is at the point on the oxyhemoglobin dissociation curve where a small change in the PaO2 will cause a large drop in the O2 saturation and a decrease in tissue oxygenation. The nurse should intervene immediately to improve the patient's oxygenation.
Question 5 of 5
What indicates a need for aggressive treatment in a patient with influenza?
Correct Answer: B
Rationale: The crackles indicate that the patient may be developing pneumonia, a common complication of influenza, which would require aggressive treatment. Myalgia, headache, mild temperature elevation, and sore throat with cough are typical manifestations of influenza and are treated with supportive care measures.
