Oxygenation NCLEX Questions Questions
Question 1 of 5
What is the first step in applying PPE for a patient that is contact/droplets precautions?
Correct Answer: B
Rationale: Hand hygiene is the first step in PPE application to ensure a clean starting point.
Question 2 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 3 of 5
Myocardial blood flow is unidirectional; the nurse knows that the correct pathway is which of the following?
Correct Answer: C
Rationale: The correct answer is C because the pathway of myocardial blood flow follows the sequence from the right atrium to the right ventricle, then to the left atrium, and finally to the left ventricle. This unidirectional flow ensures efficient oxygenation of the blood before it is pumped out to the body. Choice A is incorrect because it reverses the order of the ventricles before the atria, disrupting the normal flow of blood in the heart. Choice B is incorrect because it switches the atria before the ventricles, which is not the correct sequence of myocardial blood flow. Choice D is incorrect because it reverses the order of the ventricles, leading to inefficient oxygenation of blood before it is distributed to the body.
Question 4 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 5 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.
