Oxygenation NCLEX Questions Questions
Question 1 of 5
Inspiration and expiration are phases of which of the following processes?
Correct Answer: C
Rationale: The correct answer is C: Respiration. Inspiration and expiration are phases of the process of respiration, which involves the exchange of oxygen and carbon dioxide in the body. During inspiration, air is taken into the lungs, while during expiration, air is expelled from the lungs. Alveolar (choice A) refers to the air sacs in the lungs, not the process itself. Inhalation (choice B) is the act of breathing in, which is part of respiration but not the entire process. Sensory (choice D) does not relate to the breathing process. Therefore, the correct answer is C as it encompasses both inspiration and expiration within the process of respiration.
Question 2 of 5
A nurse is auscultating a client's heart sounds and hears a low-pitched whooshing or blowing sound over the apex of the heart. The nurse should identify which of the following?
Correct Answer: B
Rationale: The correct answer is B: Murmur. A low-pitched whooshing or blowing sound over the apex of the heart indicates the presence of a murmur, which is an abnormal heart sound caused by turbulent blood flow. This sound can be indicative of a valve disorder or structural heart abnormality. Tachycardia (A) refers to an abnormally fast heart rate and would manifest as rapid heartbeats, not as a low-pitched whooshing sound. Gallop (C) refers to abnormal heart sounds resembling the sounds of a galloping horse and is typically associated with heart failure. Stroke Volume (D) is the amount of blood pumped out of the heart with each contraction and is not related to the specific sound heard during auscultation.
Question 3 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 4 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 5 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.
