NCLEX Questions for Oxygenation Questions
Question 1 of 5
A client with chronic bronchitis reports worsening shortness of breath. What is the nurse's priority intervention?
Correct Answer: A
Rationale: The correct answer is A: Administering prescribed bronchodilators. The priority intervention for a client with chronic bronchitis experiencing worsening shortness of breath is to address the underlying cause, which is airway obstruction due to inflammation and mucus production. Bronchodilators help to open up the airways and improve airflow, providing immediate relief for shortness of breath. This intervention directly targets the client's respiratory distress and is essential for managing exacerbations of chronic bronchitis. Choice B: Encouraging pursed-lip breathing may be beneficial for some clients with chronic bronchitis but is not the priority intervention in this case. It is more of a supportive measure to help manage symptoms. Choice C: Positioning the client in high Fowler's position can help improve breathing by maximizing lung expansion, but it is not the priority intervention when the client is experiencing worsening shortness of breath. Choice D: Monitoring oxygen saturation levels is important in assessing the client's respiratory status
Question 2 of 5
A client is prescribed a long-acting beta-agonist (LABA) for asthma management. What should the nurse explain as the primary purpose of this medication?
Correct Answer: B
Rationale: The correct answer is B: To prevent asthma symptoms and attacks. Long-acting beta-agonists (LABAs) are used as maintenance therapy to prevent asthma symptoms and attacks by providing long-lasting bronchodilation. They are not meant for quick relief during an asthma attack (A), nor do they specifically target mucus production (C) or enhance short-acting bronchodilators (D). Preventing symptoms and attacks is the primary goal of using LABAs in asthma management.
Question 3 of 5
The nurse is teaching a client with obstructive sleep apnea about CPAP therapy. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Step 1: The correct answer is B because the client should not stop using CPAP therapy even if symptoms improve, as obstructive sleep apnea is a chronic condition. Step 2: Choice A is correct as consistent nightly use of CPAP is essential for managing obstructive sleep apnea. Step 3: Choice C is correct as CPAP therapy works by keeping the airway open during sleep to prevent apnea episodes. Step 4: Choice D is correct as cleaning the CPAP mask regularly is important to prevent infections and ensure effective therapy.
Question 4 of 5
Which assessment finding indicates that the nurse should take immediate action for an older patient?
Correct Answer: D
Rationale: The correct answer is D: Bilateral basilar crackles. This finding indicates fluid accumulation in the lungs, which can impede oxygenation and lead to respiratory distress in older patients. Immediate action is needed to address potential respiratory compromise. Weak cough effort (A) may also be concerning but does not require immediate action. Barrel-shaped chest (B) is associated with chronic obstructive pulmonary disease but does not warrant immediate intervention. Dry mucous membranes (C) may indicate dehydration but do not pose an immediate threat to the patient's health.
Question 5 of 5
The nurse prepares to administer a new order for a non-rebreather mask. Which action is most important for the nurse to take?
Correct Answer: A
Rationale: The correct answer is A: Ensure the reservoir bag is inflated before placing it on the patient. This is important because an inflated reservoir bag ensures a high concentration of oxygen is delivered to the patient. If the bag is not inflated, the mask will not provide the intended oxygen therapy. Choice B is incorrect as the flow rate for a non-rebreather mask is typically set at 10-15 liters per minute to ensure adequate oxygen delivery. Choice C is also incorrect as assessing the patient's ability to breathe independently is important but not the most crucial step before administering the mask. Choice D is incorrect as monitoring arterial blood gas levels is important but not the immediate action needed before administering the mask.
