Oxygenation NCLEX Questions Questions
Question 1 of 5
A nurse is monitoring a client on a ventilator for acute respiratory distress syndrome (ARDS). Which finding requires immediate action?
Correct Answer: C
Rationale: The correct answer is C: Peak inspiratory pressure of 35 cm H2O. A peak inspiratory pressure of 35 cm H2O indicates high airway pressure, which can lead to barotrauma and further lung damage in a client with ARDS. Immediate action is needed to prevent complications. A: Oxygen saturation of 92% is slightly low but not critically concerning in this context. B: Tidal volume of 450 mL is within the normal range and does not indicate an immediate issue. D: Respiratory rate of 18 breaths per minute is within normal limits and does not require immediate action.
Question 2 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 3 of 5
The nurse is caring for a client with acute respiratory distress syndrome (ARDS). What position is most effective in improving oxygenation?
Correct Answer: B
Rationale: The correct answer is B: Prone position. Placing the client in the prone position improves oxygenation in ARDS by enhancing ventilation-perfusion matching, reducing lung compression, and increasing alveolar recruitment. This position helps to improve oxygenation by allowing for more uniform distribution of ventilation throughout the lungs. The other choices (A: Supine position, C: High Fowler's position, D: Side-lying position) do not provide the same benefits for oxygenation in ARDS. Supine position may worsen oxygenation due to increased pressure on the diaphragm, High Fowler's position may not optimize lung expansion, and Side-lying position may not effectively improve ventilation/perfusion matching.
Question 4 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 5 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.
