Nursing Questions on Oxygenation Questions
Question 1 of 5
A nurse is teaching a client about using a peak flow meter. Which of the following instructions should the nurse include?
Correct Answer: C
Rationale: The correct answer is C because repeating the test three times and recording the highest reading helps ensure accuracy and consistency in monitoring the client's peak flow. This method accounts for any variability in the client's effort or technique. Option A is incorrect as inhaling deeply before using the peak flow meter may affect the accuracy of the reading. Option B is incorrect because performing the test before taking any bronchodilator medication may not reflect the client's actual lung function. Option D is incorrect as exhaling slowly into the device is not the recommended technique for using a peak flow meter accurately.
Question 2 of 5
The nurse is caring for a client with pulmonary embolism (PE). Which clinical sign is most concerning?
Correct Answer: D
Rationale: The correct answer is D because a low oxygen saturation level of 85% indicates poor oxygen exchange in the lungs, which can be life-threatening in a PE. Step 1: Oxygen saturation is a direct measure of how well the lungs are oxygenating the blood, making it a critical parameter in PE. Step 2: A low oxygen saturation level can lead to tissue hypoxia and organ dysfunction. Step 3: Prompt intervention is necessary to improve oxygenation and prevent further complications. Choices A, B, and C are important but not as immediately concerning as a low oxygen saturation level in a client with PE.
Question 3 of 5
A client is being evaluated for chronic bronchitis. Which symptom is most indicative of this condition?
Correct Answer: C
Rationale: Correct Answer: C - Chronic productive cough Rationale: 1. Chronic bronchitis is characterized by long-standing inflammation of the bronchial tubes leading to excessive mucus production. 2. A chronic productive cough, which lasts for at least 3 months in 2 consecutive years, is a hallmark symptom of chronic bronchitis. 3. Frequent respiratory infections (A) may occur but are not specific to chronic bronchitis. 4. A barrel-shaped chest (B) is seen in advanced stages of COPD, not specific to chronic bronchitis. 5. Wheezing and dyspnea (D) are more commonly associated with asthma or COPD, not specific to chronic bronchitis.
Question 4 of 5
The nurse is caring for a client with a newly inserted chest tube. Which observation would require immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because a chest tube dressing saturated with blood indicates active bleeding, which can lead to complications like hemorrhage or tension pneumothorax. Immediate intervention is needed to prevent further issues. A: Serosanguinous drainage is expected initially after chest tube insertion. C: Intermittent bubbling in the water seal chamber is normal and indicates proper functioning. D: Chest tube secured with tape and sutures is appropriate for stabilization.
Question 5 of 5
The nurse is evaluating a client with bronchitis. Which symptom is most concerning?
Correct Answer: C
Rationale: The correct answer is C: Shortness of breath at rest. This symptom is concerning as it indicates severe respiratory distress, potentially leading to respiratory failure. Shortness of breath at rest is a red flag for worsening bronchitis or complications like pneumonia. A: Persistent productive cough is common in bronchitis and may indicate ongoing inflammation or infection. It is not as immediately concerning as shortness of breath at rest. B: Yellow-green sputum suggests a bacterial infection, but it is not as urgent as shortness of breath at rest. D: Low-grade fever is a common symptom of bronchitis and may not indicate a severe condition unless it persists or worsens.
