Oxygenation NCLEX Questions Questions
Question 1 of 5
A nurse is caring for a client who is post-operative following a lobectomy. Which of the following actions should the nurse take to prevent complications?
Correct Answer: B
Rationale: The correct answer is B: Encourage the client to use an incentive spirometer. This action helps prevent complications by promoting deep breathing, improving lung expansion, and preventing respiratory complications such as pneumonia and atelectasis. Incentive spirometry aids in clearing secretions and maintaining optimal lung function post-operatively. A: Limiting the client's fluid intake is not recommended as adequate hydration is essential for post-operative recovery and preventing complications. C: Placing the client in a supine position can lead to decreased lung expansion and increase the risk of respiratory complications. D: Administering pain medication to suppress coughing is not ideal as coughing is necessary for clearing secretions and preventing respiratory complications.
Question 2 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 3 of 5
The nurse is reviewing discharge instructions with a client who has a tracheostomy. What should the nurse emphasize?
Correct Answer: B
Rationale: The correct answer is B because using sterile technique for tracheostomy care helps prevent infections. Sterile technique minimizes the risk of introducing harmful bacteria into the tracheostomy site, reducing the chance of complications. Changing tracheostomy ties daily (Option A) may not be necessary unless they are soiled or wet. Avoiding humidification (Option C) can lead to mucus buildup and blockage, causing breathing difficulties. Cleaning the stoma site with alcohol daily (Option D) can irritate the skin and increase the risk of infection.
Question 4 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 5 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.
