NCLEX Questions for Oxygenation Questions
Question 1 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 2 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 3 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.
Question 4 of 5
Which assessment finding in a patient with pneumonia requires the nurse to intervene immediately?
Correct Answer: C
Rationale: The correct answer is C because an oxygen saturation of 86% indicates severe hypoxemia, which can lead to tissue damage and organ dysfunction. The nurse should intervene immediately to improve oxygenation. A weak productive cough (Choice A) may indicate impaired airway clearance but does not require immediate intervention. Pleuritic chest pain (Choice B) is common in pneumonia but does not indicate an immediate threat to the patient's life. Coarse crackles in the lower lobes (Choice D) are typical findings in pneumonia but do not necessitate immediate action unless accompanied by severe respiratory distress.
Question 5 of 5
The nurse is caring for a patient with a tracheostomy who has thick secretions. Which action is most appropriate?
Correct Answer: A
Rationale: The correct answer is A: Perform tracheostomy suctioning using sterile technique. This is the most appropriate action because thick secretions can obstruct the tracheostomy tube, leading to respiratory distress. Suctioning helps clear the airway and maintain patency. Sterile technique is crucial to prevent introducing infection. Incorrect Choices: B: Increasing oxygen flow does not directly address the issue of thick secretions in the tracheostomy tube. C: Instilling normal saline may further increase secretions and can potentially cause aspiration. D: Encouraging the patient to take deep breaths may not effectively clear the thick secretions from the tracheostomy tube.
