NCLEX Style Questions on Oxygenation Questions
Question 1 of 5
The nurse would expect which change in cardiac output for a patient with fluid volume overload?
Correct Answer: A
Rationale: The correct answer is A: Increased preload. Fluid volume overload increases the volume of blood in the heart chambers, leading to increased stretching of the heart muscle fibers (preload). This results in an increase in cardiac output. B: Decreased afterload is not expected with fluid volume overload as afterload refers to the resistance the heart must overcome to eject blood. C: Decreased tissue perfusion is not directly related to fluid volume overload, as it is more indicative of inadequate blood flow to tissues. D: Increased heart rate is not a direct effect of fluid volume overload but may occur as a compensatory mechanism in some cases.
Question 2 of 5
The nurse has completed the assessment for a client in the clinic with a diagnosis of chronic asthma. What would be the priority goal the nurse should discuss with the client?
Correct Answer: C
Rationale: The correct answer is C: Recognizing triggers that cause asthma attacks. This is the priority goal because identifying triggers helps the client avoid or minimize asthma attacks, leading to better management of the condition. By recognizing triggers, the client can take proactive measures to prevent exacerbations. Choices A, B, and D are important aspects of asthma management, but recognizing triggers is crucial for preventing asthma attacks and improving overall quality of life. Maintaining a regular exercise routine (A) can be beneficial but may not be the priority if triggers are not controlled. Complying with medication instructions (B) is important for treatment adherence, but identifying triggers can help reduce the need for rescue medications. Understanding physical limitations (D) is important for self-management, but recognizing triggers is more directly related to preventing asthma exacerbations.
Question 3 of 5
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with increased dyspnea. Which laboratory test result requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B: PaO2 of 55 mmHg. In a client with COPD and increased dyspnea, a low PaO2 indicates hypoxemia, which can lead to respiratory failure. Immediate intervention is needed to improve oxygenation and prevent complications. Option A is within normal range for hemoglobin. Option C shows a normal pH level, indicating no immediate acid-base imbalance. Option D reveals a normal HCO3 level, suggesting no immediate metabolic imbalance. Therefore, the critical issue in this scenario is the low PaO2 level, requiring prompt attention.
Question 4 of 5
The nurse is caring for a client post-lobectomy. What is the most important nursing action to prevent complications?
Correct Answer: B
Rationale: The correct answer is B: Encouraging frequent use of the incentive spirometer. Post-lobectomy, the risk of atelectasis is high due to decreased lung capacity. Incentive spirometer helps prevent this by promoting deep breathing and lung expansion. Administering analgesics (A) is important, but not the most crucial. Limiting fluid intake (C) is incorrect as hydration is essential post-surgery. Positioning the client on the operative side (D) can hinder lung expansion.
Question 5 of 5
The nurse is caring for a client with pneumothorax who has a chest tube. What intervention should the nurse prioritize?
Correct Answer: C
Rationale: The correct answer is C: Keeping the drainage system below the chest level. This is crucial to ensure proper drainage and prevent air from entering the pleural space. Placing the system below the chest level allows gravity to assist in drainage. Choice A is incorrect because ambulation may increase the risk of dislodging the chest tube. Choice B is incorrect as clamping the chest tube can lead to tension pneumothorax. Choice D is incorrect as changing the chest tube dressing daily is not a priority over maintaining proper positioning of the drainage system.
