NCLEX Questions for Oxygenation Questions
Question 1 of 5
A client is experiencing respiratory acidosis. What is the nurse's priority intervention?
Correct Answer: D
Rationale: The correct answer is D. Positioning the client to promote lung expansion is the priority intervention for a client experiencing respiratory acidosis as it helps improve ventilation and oxygenation. This intervention helps optimize lung function and can aid in correcting the acidosis by increasing the efficiency of gas exchange. Administering a bronchodilator (A) may help with bronchoconstriction but is not the priority in this situation. Initiating deep breathing exercises (B) may be helpful in some cases but may not be appropriate for a client in respiratory distress. Providing supplemental oxygen (C) may help improve oxygenation, but without addressing the underlying cause of the acidosis, it may not fully resolve the issue.
Question 2 of 5
A client with chronic bronchitis reports worsening shortness of breath. What is the nurse's priority intervention?
Correct Answer: A
Rationale: The correct answer is A: Administering prescribed bronchodilators. The priority intervention for a client with chronic bronchitis experiencing worsening shortness of breath is to address the underlying cause, which is airway obstruction due to inflammation and mucus production. Bronchodilators help to open up the airways and improve airflow, providing immediate relief for shortness of breath. This intervention directly targets the client's respiratory distress and is essential for managing exacerbations of chronic bronchitis. Choice B: Encouraging pursed-lip breathing may be beneficial for some clients with chronic bronchitis but is not the priority intervention in this case. It is more of a supportive measure to help manage symptoms. Choice C: Positioning the client in high Fowler's position can help improve breathing by maximizing lung expansion, but it is not the priority intervention when the client is experiencing worsening shortness of breath. Choice D: Monitoring oxygen saturation levels is important in assessing the client's respiratory status
Question 3 of 5
The nurse is assessing a client with pulmonary hypertension. Which symptom is most commonly associated with this condition?
Correct Answer: B
Rationale: The correct answer is B, peripheral edema and dyspnea on exertion. In pulmonary hypertension, increased pressure in the pulmonary arteries can lead to right-sided heart failure, causing symptoms like peripheral edema and dyspnea on exertion. Productive cough with green sputum (A) is more commonly associated with respiratory infections. Frequent upper respiratory infections (C) may indicate issues with the upper airways, not specifically pulmonary hypertension. Intermittent chest pain at rest (D) is less likely to be associated with pulmonary hypertension, as it is more commonly seen with other cardiovascular conditions.
Question 4 of 5
A client is prescribed a long-acting beta-agonist (LABA) for asthma management. What should the nurse explain as the primary purpose of this medication?
Correct Answer: B
Rationale: The correct answer is B: To prevent asthma symptoms and attacks. Long-acting beta-agonists (LABAs) are used as maintenance therapy to prevent asthma symptoms and attacks by providing long-lasting bronchodilation. They are not meant for quick relief during an asthma attack (A), nor do they specifically target mucus production (C) or enhance short-acting bronchodilators (D). Preventing symptoms and attacks is the primary goal of using LABAs in asthma management.
Question 5 of 5
The nurse is teaching a client with obstructive sleep apnea about CPAP therapy. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Step 1: The correct answer is B because the client should not stop using CPAP therapy even if symptoms improve, as obstructive sleep apnea is a chronic condition. Step 2: Choice A is correct as consistent nightly use of CPAP is essential for managing obstructive sleep apnea. Step 3: Choice C is correct as CPAP therapy works by keeping the airway open during sleep to prevent apnea episodes. Step 4: Choice D is correct as cleaning the CPAP mask regularly is important to prevent infections and ensure effective therapy.
