Oxygen Questions and Answers PDF Questions
Question 1 of 5
A client with pulmonary fibrosis is being treated with supplemental oxygen. What is the primary goal of oxygen therapy in this condition?
Correct Answer: B
Rationale: The primary goal of oxygen therapy in pulmonary fibrosis is to reduce the work of breathing. Pulmonary fibrosis causes stiffening and scarring of the lung tissue, making breathing more difficult. Supplemental oxygen helps improve oxygen levels in the blood, reducing the effort required to breathe. This can alleviate symptoms such as shortness of breath and improve the client's quality of life. Explanation of why other choices are incorrect: A: Oxygen therapy does not cure pulmonary fibrosis. It only helps manage symptoms. C: Oxygen therapy does not eliminate the need for medications in pulmonary fibrosis. Medications may still be necessary to manage the underlying condition. D: Oxygen therapy does not aim to prevent respiratory alkalosis in pulmonary fibrosis. It primarily focuses on improving oxygenation and reducing the work of breathing.
Question 2 of 5
The nurse is caring for a client who is intubated and on mechanical ventilation. Which action is most effective in preventing ventilator-associated pneumonia (VAP)?
Correct Answer: B
Rationale: The correct answer is B: Providing oral care with chlorhexidine. This is because oral care helps reduce the bacteria in the mouth that can be aspirated into the lungs, leading to VAP. Regular oral care with chlorhexidine can prevent colonization of harmful bacteria in the oral cavity, reducing the risk of VAP. Administering antibiotics won't prevent VAP but treat infections. Suctioning every hour can increase the risk of infection, and elevating the head of the bed to 15 degrees may help prevent aspiration but is not as effective as proper oral care in preventing VAP.
Question 3 of 5
A client is receiving oxygen via a non-rebreather mask. What is the most important nursing assessment?
Correct Answer: A
Rationale: The correct answer is A: Ensuring the reservoir bag remains inflated. This is crucial as it indicates the client is receiving the intended high-flow oxygen without rebreathing exhaled CO2. If the bag deflates, it suggests a leak or inadequate flow. Option B is not relevant as the flow rate for a non-rebreather mask is typically higher. Option C is less critical than ensuring oxygen delivery. Option D is important but not the priority when the client's oxygenation is at stake.
Question 4 of 5
A client with a history of COPD reports increasing dyspnea. What is the nurse's priority assessment?
Correct Answer: A
Rationale: The correct answer is A: Oxygen saturation levels. This is the priority assessment because in a client with a history of COPD experiencing increasing dyspnea, it is crucial to assess their oxygen saturation levels to determine if they are hypoxic. Hypoxia can exacerbate COPD symptoms and lead to respiratory distress. Monitoring oxygen saturation levels helps in assessing the effectiveness of respiratory interventions. Choice B (Heart rate and blood pressure) is important but not the priority as hypoxia can directly impact these vital signs. Choice C (Capillary refill time) is more relevant for assessing perfusion in cardiovascular conditions. Choice D (Level of consciousness) is important but assessing oxygen saturation levels takes precedence in a client with COPD and worsening dyspnea.
Question 5 of 5
The nurse is evaluating the effectiveness of a bronchodilator for a client with asthma. Which finding indicates improvement?
Correct Answer: A
Rationale: The correct answer is A: Decreased wheezing on auscultation. Wheezing is a common symptom of asthma due to narrowed airways. Improvement in asthma would lead to decreased wheezing as the airways open up, allowing for better airflow. This indicates that the bronchodilator is effectively working to dilate the airways and improve respiratory function. Choice B: Respiratory rate increased to 24 breaths per minute is incorrect as an increased respiratory rate could indicate respiratory distress or worsening of asthma symptoms. Choice C: Heart rate increased to 110 beats per minute is incorrect as an increased heart rate could indicate stress or anxiety, not necessarily improvement in asthma. Choice D: Mild hand tremors reported by the client is incorrect as hand tremors are a common side effect of bronchodilators and not a direct indicator of asthma improvement.
