Oxygenation NCLEX Questions Questions
Question 1 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 2 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 3 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 4 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 5 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.
