NCLEX Questions for Oxygenation Questions
Question 1 of 5
A nurse is assessing a client with suspected pulmonary embolism. Which clinical finding is most concerning?
Correct Answer: C
Rationale: The correct answer is C: Oxygen saturation of 87%. In pulmonary embolism, decreased oxygen saturation indicates impaired gas exchange due to reduced blood flow to the lungs. This is concerning as it can lead to hypoxemia and tissue damage. Respiratory rate (choice B) and heart rate (choice D) can be elevated in response to hypoxemia but are not as direct indicators of impaired gas exchange. Chest pain and hemoptysis (choice A) are common symptoms of pulmonary embolism but do not directly reflect the severity of oxygenation impairment.
Question 2 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 3 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 4 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.
Question 5 of 5
Which assessment finding indicates that the nurse should take immediate action for an older patient?
Correct Answer: D
Rationale: The correct answer is D: Bilateral basilar crackles. This finding indicates fluid accumulation in the lungs, which can impede oxygenation and lead to respiratory distress in older patients. Immediate action is needed to address potential respiratory compromise. Weak cough effort (A) may also be concerning but does not require immediate action. Barrel-shaped chest (B) is associated with chronic obstructive pulmonary disease but does not warrant immediate intervention. Dry mucous membranes (C) may indicate dehydration but do not pose an immediate threat to the patient's health.
