Nursing Questions on Oxygenation Questions
Question 1 of 5
The nurse is providing discharge instructions to a client with obstructive sleep apnea. Which instruction is most important?
Correct Answer: A
Rationale: The correct answer is A: Use a CPAP machine every night. This is crucial for managing obstructive sleep apnea by ensuring continuous positive airway pressure during sleep, preventing airway collapse. Choice B is not directly related to managing sleep apnea. Choice C is dangerous as sleeping pills can worsen sleep apnea. Choice D may offer temporary relief but does not address the underlying issue of airway obstruction. Using a CPAP machine consistently is the gold standard treatment for obstructive sleep apnea, ensuring adequate airflow and oxygenation during sleep.
Question 2 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 3 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 4 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.
Question 5 of 5
A client with bronchitis is prescribed guaifenesin. What is the primary purpose of this medication?
Correct Answer: B
Rationale: Step 1: Guaifenesin is an expectorant that works by thinning mucus in the airways. Step 2: Thinning mucus helps to make it easier for the client to cough up and clear the mucus. Step 3: This promotes expectoration, which helps to relieve congestion and improve breathing. Step 4: Therefore, the primary purpose of guaifenesin is to thin mucus and promote expectoration in clients with bronchitis.
