Oxygen Therapy NCLEX Questions Questions
Question 1 of 5
The nurse prepares a patient for a pulmonary function test. Which instruction is appropriate?
Correct Answer: A
Rationale: The correct answer is A because smoking can affect lung function test results. Nicotine and other chemicals in cigarettes can cause airway constriction and air sac damage, leading to inaccurate results. Option B is incorrect because bronchodilators can alter test results. Option C is incorrect as fasting may be required to avoid interference from food. Option D is incorrect because the patient should follow specific positioning instructions as lying flat can affect breathing during the test.
Question 2 of 5
A patient with a tracheostomy tube cannot cough up secretions effectively. What should the nurse do next?
Correct Answer: C
Rationale: The correct answer is C: Use sterile gloves and perform suctioning. This is the appropriate action to help the patient with a tracheostomy tube who cannot cough up secretions effectively. Suctioning helps clear the airway of secretions and prevents complications such as respiratory distress. Encouraging the use of an incentive spirometer (A) is not effective in clearing secretions directly. Promoting increased oral fluid intake (B) may not address the immediate need for clearing secretions. Preoxygenating the patient (D) before suctioning is not the next step but rather a precautionary measure during the suctioning process.
Question 3 of 5
The nurse observes continuous bubbling in the water-seal chamber of a chest tube. What should the nurse do?
Correct Answer: B
Rationale: The correct answer is B: Check for loose connections in the system. Continuous bubbling in the water-seal chamber indicates an air leak in the chest tube system. The nurse should first check for loose connections, as this is a common cause of air leaks. Clamping the chest tube (choice A) could lead to tension pneumothorax. Replacing the entire system (choice C) may not be necessary if the issue is a simple loose connection. Notifying the healthcare provider (choice D) can be done after checking for loose connections to provide an update on the situation.
Question 4 of 5
A patient with pleural effusion is scheduled for a thoracentesis. What is the nurse's role during the procedure?
Correct Answer: D
Rationale: The correct answer is D because providing emotional support and monitoring vital signs are essential roles for the nurse during a thoracentesis procedure. Emotional support helps to reduce anxiety and promote patient comfort. Monitoring vital signs ensures patient safety and early detection of any complications. Choice A (monitor oxygen saturation continuously) is not typically necessary during a thoracentesis unless the patient is at high risk for respiratory compromise. Choice B (instruct the patient to hold their breath) is incorrect as the patient is usually instructed to breathe normally or take shallow breaths during the procedure to minimize movement. Choice C (position the patient on the affected side) is also incorrect as the patient is typically positioned sitting upright or slightly leaning forward to facilitate access to the pleural space.
Question 5 of 5
The nurse prepares a patient for a bronchoscopy. What is the most important pre-procedure instruction?
Correct Answer: A
Rationale: The correct answer is A: Avoid eating or drinking for 6-8 hours before the procedure. This instruction is crucial to prevent aspiration during bronchoscopy. Eating or drinking can lead to vomiting, which poses a risk during the procedure. Choice B is incorrect as some medications may need to be avoided before the procedure. Choice C is incorrect as chest discomfort is not expected during the procedure. Choice D is incorrect as deep breathing exercises are not typically required before bronchoscopy.
