Oxygenation NCLEX Questions with Rationale Questions
Question 1 of 5
The nurse is assessing a client with sleep apnea. Which symptom is most commonly associated with this condition?
Correct Answer: A
Rationale: The correct answer is A: Morning headaches. 1. Sleep apnea causes intermittent pauses in breathing during sleep, leading to low oxygen levels and frequent awakenings, resulting in morning headaches. 2. Frequent nighttime urination (B) is not typically associated with sleep apnea. 3. Unexplained weight loss (C) is not a common symptom of sleep apnea. 4. Persistent dry cough (D) is more commonly associated with conditions like asthma or GERD, not sleep apnea.
Question 2 of 5
A client with pulmonary fibrosis is receiving supplemental oxygen. What is the primary goal of oxygen therapy in this condition?
Correct Answer: B
Rationale: The primary goal of oxygen therapy in pulmonary fibrosis is to maintain tissue oxygenation. Pulmonary fibrosis causes scarring of the lungs, leading to impaired gas exchange and reduced oxygen levels in the blood. Supplemental oxygen helps to ensure that the tissues receive an adequate supply of oxygen, preventing hypoxemia and tissue damage. - A: Oxygen therapy does not cure pulmonary fibrosis but helps manage symptoms. - C: Oxygen therapy may prevent acute exacerbations but may not always prevent the need for mechanical ventilation. - D: While oxygen therapy can improve exercise tolerance temporarily, it does not offer a permanent solution for pulmonary fibrosis.
Question 3 of 5
A client with asthma is prescribed a short-acting beta-agonist (SABA) inhaler. When should the client use this medication?
Correct Answer: B
Rationale: The correct answer is B: Before engaging in exercise. SABAs are used as quick-relief medications to provide immediate relief of asthma symptoms, such as shortness of breath and wheezing. Using the inhaler before exercise helps prevent exercise-induced bronchoconstriction by opening up the airways. Option A is incorrect because using SABA daily at bedtime is not recommended and can lead to overuse. Option C is incorrect as SABA should be used as needed for quick relief, not necessarily after taking a corticosteroid inhaler. Option D is incorrect because SABA should be used not only during severe asthma attacks but also before physical activity to prevent symptoms.
Question 4 of 5
The nurse observes a student who is listening to a patient's lungs. Which action by the student indicates a need to review respiratory assessment skills?
Correct Answer: B
Rationale: The correct answer is B because the student should listen during both inspiratory and expiratory phases without moving the stethoscope in between. This ensures a comprehensive assessment of lung sounds. Choice A is correct as comparing breath sounds from side to side is a good practice. Choice C is also correct as starting at the apices and moving down towards the bases is a proper technique. Choice D is incorrect because instructing the patient to breathe slowly and deeply is a standard instruction for a respiratory assessment.
Question 5 of 5
The nurse assesses a patient with a pleural effusion. Which action should the nurse take to prepare the patient for thoracentesis?
Correct Answer: B
Rationale: The correct answer is B because positioning the patient sitting up on the side of the bed allows for better access to the thoracic cavity during thoracentesis. This position helps to maximize lung expansion, making it easier for the healthcare provider to access the pleural effusion. Starting a peripheral IV line to administer sedatives (Choice A) is not necessary for thoracentesis preparation. Obtaining a collection device to hold 3 liters of pleural fluid (Choice C) is not a necessary step for preparing the patient for the procedure. Reminding the patient not to eat or drink for 6 hours (Choice D) is not a standard requirement for thoracentesis preparation.
