Oxygen Cycle Questions and Answers Questions
Question 1 of 5
A patient is admitted with a history of asthma and is experiencing wheezing and shortness of breath. What is the priority intervention?
Correct Answer: B
Rationale: The correct answer is B: Administer corticosteroids. In the scenario described, the priority intervention is to administer corticosteroids to reduce airway inflammation and improve breathing in an acute asthma exacerbation. This treatment addresses the underlying cause of the symptoms and helps to prevent further complications. Nebulized bronchodilators (choice A) and inhalers (choice C) are important treatments for asthma but are typically used after corticosteroids to provide immediate relief of symptoms. Administering subcutaneous insulin (choice D) is not relevant to the management of asthma and would not address the patient's respiratory distress.
Question 2 of 5
A nurse is caring for a patient with a history of asthma. The patient is experiencing difficulty breathing. What is the priority intervention?
Correct Answer: A
Rationale: The correct answer is A: Administer a bronchodilator. This is the priority intervention because the patient is experiencing difficulty breathing, indicating an asthma exacerbation. Administering a bronchodilator helps to open up the airways and improve breathing. It targets the underlying cause of the respiratory distress. Administering IV fluids (choices B and C) may be necessary for hydration but is not the priority in this situation. Administering pain relief (choice D) is not appropriate as the priority is addressing the breathing difficulty.
Question 3 of 5
A patient in metabolic alkalosis is admitted to the emergency department and pulse oximetry (SpO₂) indicates that the O₂ saturation is 94%. Which action should the nurse expect to take next?
Correct Answer: D
Rationale: Metabolic alkalosis requires ABG confirmation to assess pH and CO₂ levels, guiding treatment.
Question 4 of 5
The nurse is caring for a hospitalized older patient who has nasal packing in place after a nosebleed. Which assessment finding will require the most immediate action by the nurse?
Correct Answer: A
Rationale: An SpO₂ of 89% indicates hypoxemia, requiring immediate action to improve oxygenation.
Question 5 of 5
A lobectomy is scheduled for a patient with stage I non-small cell lung cancer. The patient tells the nurse, 'I would rather have chemotherapy than surgery.' Which response by the nurse is most appropriate?
Correct Answer: C
Rationale: Exploring the patient's understanding allows the nurse to address misconceptions and provide education tailored to their concerns.
