Oxygen Therapy NCLEX Questions Questions
Question 1 of 5
The nurse is teaching a client with asthma about identifying triggers. Which trigger is most commonly associated with asthma attacks?
Correct Answer: A
Rationale: The correct answer is A: Cold air. Cold air is a common trigger for asthma attacks as it can cause airways to constrict and become inflamed, leading to difficulty breathing. Cold air can also worsen existing asthma symptoms. Loud noises (B), lack of sleep (C), and physical inactivity (D) are not typically associated with triggering asthma attacks. Loud noises may exacerbate stress but do not directly trigger asthma. Lack of sleep and physical inactivity can impact overall health but are not primary triggers for asthma attacks.
Question 2 of 5
The nurse completes a shift assessment on a patient admitted in the early phase of heart failure. When auscultating the patient's lungs, which finding would the nurse most likely hear?
Correct Answer: C
Rationale: The correct answer is C: Discontinuous, high-pitched sounds of short duration during inspiration. In heart failure, the patient may develop pulmonary edema leading to crackles or fine rales on auscultation, which are best heard during inspiration due to the opening of collapsed alveoli. This is characterized by short-duration, high-pitched sounds. Option A is more indicative of rhonchi, commonly heard in conditions like bronchitis. Option B describes wheezes typically found in asthma or COPD. Option D describes coarse crackles, which are heard in conditions like pneumonia. Therefore, the most likely finding in a patient with early heart failure would be discontinuous, high-pitched sounds during inspiration.
Question 3 of 5
Which intervention will the nurse include in the plan of care for a patient diagnosed with a lung abscess?
Correct Answer: B
Rationale: The correct answer is B: Assist the patient with chest physiotherapy and postural drainage. This intervention helps mobilize secretions in the lungs, aiding in the drainage of the abscess. Chest physiotherapy can improve ventilation and oxygenation. A: Avoiding over-the-counter expectorants is not directly related to managing a lung abscess. They may not be effective for this condition. C: Notifying the healthcare provider about bloody or foul-smelling sputum is important, but it is not a direct intervention for managing a lung abscess. D: Teaching about the need for prolonged antibiotic therapy is important, but the immediate intervention for a lung abscess is to assist with chest physiotherapy and postural drainage to improve outcomes.
Question 4 of 5
A patient is admitted with acute respiratory distress syndrome (ARDS). Which assessment finding is most concerning?
Correct Answer: A
Rationale: The correct answer is A: SpO2 of 86% despite high-flow oxygen. This finding is most concerning as it indicates severe hypoxemia despite maximal oxygen therapy, which is a critical sign of ARDS. Hypoxemia is the main feature of ARDS and can rapidly lead to organ failure. Choice B (Respiratory rate of 24 breaths per minute) is within normal range and may not be as concerning in isolation. Choice C (Fine crackles in bilateral lung bases) is common in ARDS but may not necessarily indicate severity. Choice D (Heart rate of 102 beats per minute) is elevated but not as immediately life-threatening as severe hypoxemia.
Question 5 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.
