Oxygenation NCLEX Questions Questions
Question 1 of 5
A client is using a metered-dose inhaler (MDI) for the first time. What is the correct sequence for its use?
Correct Answer: A
Rationale: The correct sequence for using a metered-dose inhaler (MDI) for the first time is A: Shake the inhaler, exhale fully, press the inhaler while inhaling deeply, hold breath for 10 seconds. Rationale: 1. Shake the inhaler: This helps to mix the medication properly. 2. Exhale fully: Emptying the lungs before inhaling ensures better medication delivery. 3. Press the inhaler while inhaling deeply: This allows the medication to reach deep into the lungs. 4. Hold breath for 10 seconds: Holding the breath allows the medication to be absorbed effectively. Summary of other choices: B: Incorrect because inhaling quickly may lead to improper medication delivery. C: Incorrect because pressing the inhaler before inhaling may result in less effective medication delivery. D: Incorrect because shaking the inhaler after pressing it may disrupt the medication dispersion.
Question 2 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 3 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 4 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 5 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.
