Oxygen Therapy NCLEX Questions Questions
Question 1 of 5
The nurse teaches a patient about smoking cessation to reduce the risk of lung cancer. Which statement by the patient indicates effective learning?
Correct Answer: B
Rationale: Rationale: Choice B is correct because stopping smoking reduces the risk of lung cancer, even if the patient has smoked for years. Nicotine and other harmful chemicals in cigarettes damage the lungs, but quitting smoking allows the body to repair itself and lowers the risk of developing lung cancer. Choices A, C, and D are incorrect because cutting back on cigarettes still exposes the patient to harmful chemicals, chest x-rays are not recommended as a screening tool for lung cancer in the general population, and vitamins do not prevent lung cancer if the patient continues smoking.
Question 2 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 3 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 4 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 5 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.
