Oxygen Therapy NCLEX Questions Questions
Question 1 of 5
A patient with pneumonia is ordered a sputum culture. When should the nurse collect the specimen?
Correct Answer: B
Rationale: The correct answer is B because collecting sputum first thing in the morning before eating or drinking ensures a concentrated sample and reduces contamination. Choice A is incorrect as starting antibiotic therapy may alter the results. Choice C is incorrect as food particles can contaminate the sample. Choice D is incorrect as bronchodilators can affect the sputum consistency.
Question 2 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 3 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 4 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.
Question 5 of 5
Which intervention is most effective for preventing ventilator-associated pneumonia (VAP)?
Correct Answer: A
Rationale: The correct answer is A: Performing oral care with chlorhexidine. This intervention is most effective for preventing VAP because it helps reduce the colonization of pathogenic bacteria in the oral cavity, which can be aspirated into the lungs. Chlorhexidine is an antiseptic agent that can effectively reduce the risk of developing pneumonia. Summary of other choices: B: Changing ventilator tubing every shift - While maintaining clean ventilator tubing is important for infection prevention, it is not the most effective intervention for preventing VAP. C: Suctioning the patient hourly - Frequent suctioning may be necessary for airway clearance, but it is not specifically targeted at preventing VAP. D: Keeping the patient sedated continuously - Continuous sedation may lead to complications such as prolonged ventilation and increased risk of pneumonia. It is not a recommended strategy for preventing VAP.
