Oxygenation NCLEX Questions Questions
Question 1 of 5
A client with chronic bronchitis has been prescribed a corticosteroid inhaler. What teaching point is most important?
Correct Answer: B
Rationale: The correct answer is B: Rinse your mouth after each use. This is important because corticosteroid inhalers can increase the risk of developing oral thrush, a fungal infection in the mouth. Rinsing the mouth after each use helps to reduce this risk. Choice A is incorrect because corticosteroid inhalers are not just for asthma attacks but are meant for regular use in chronic conditions like bronchitis. Choice C is incorrect because taking the inhaler with meals is not necessary for its effectiveness. Choice D is incorrect because while using a spacer can improve medication delivery, rinsing the mouth is more crucial for preventing oral thrush.
Question 2 of 5
A client with pneumonia reports pleuritic chest pain. What intervention should the nurse implement to promote comfort?
Correct Answer: B
Rationale: Correct Answer: B - Administer prescribed analgesics. Rationale: 1. Pleuritic chest pain in pneumonia is caused by inflammation of the pleura. 2. Analgesics help reduce pain by blocking pain signals. 3. Encouraging coughing and deep breathing may exacerbate pain. 4. Positioning flat can worsen pain due to pressure on the chest. 5. Increasing fluid intake may help with secretions but won't directly address the pain.
Question 3 of 5
The nurse is assessing a client with emphysema. Which physical assessment finding is most characteristic of this condition?
Correct Answer: A
Rationale: The correct answer is A: Barrel-shaped chest. Emphysema is characterized by hyperinflation of the lungs, leading to a barrel-shaped chest due to increased lung volume. This results from air trapping and loss of lung elasticity. Dullness to percussion (B) is associated with pleural effusion or consolidation, not emphysema. Increased fremitus (C) is seen in conditions with increased lung density, not in emphysema. Inspiratory crackles (D) are indicative of conditions such as pneumonia or heart failure, not emphysema.
Question 4 of 5
A client with pneumonia is receiving antibiotics. Which action is most important to ensure effective treatment?
Correct Answer: B
Rationale: The correct answer is B. Collecting a sputum culture before administering antibiotics is crucial to identify the specific pathogen causing the pneumonia. This allows for targeted antibiotic therapy, improving treatment effectiveness. Encouraging oral fluid intake (A) is important but not as critical as identifying the pathogen. Administering antipyretics (C) may provide symptomatic relief but does not address the underlying infection. Monitoring white blood cell count (D) is general and may not provide specific information needed for effective treatment.
Question 5 of 5
The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?
Correct Answer: D
Rationale: The correct answer is D. A PaO2 level of 59 mm Hg indicates severe hypoxemia, which requires immediate action to ensure adequate oxygen delivery to tissues. Normal PaO2 levels are typically above 80 mm Hg. Low PaO2 can lead to tissue hypoxia and is a critical finding that needs prompt intervention. Choice A (HCO3– of 31 mEq/L) is slightly elevated but does not require immediate action. Choice B (SaO2 of 92%) is within the normal range and does not indicate an urgent issue. Choice C (PaCO2 of 31 mm Hg) is also within the normal range and does not necessitate immediate intervention. In summary, the correct answer is D because a low PaO2 level signifies severe hypoxemia, requiring prompt attention to prevent potential complications.
