NCLEX Questions for Oxygenation Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse prepares to administer a new order for a non-rebreather mask. Which action is most important for the nurse to take?
Correct Answer: A
Rationale: The correct answer is A: Ensure the reservoir bag is inflated before placing it on the patient. This is important because an inflated reservoir bag ensures a high concentration of oxygen is delivered to the patient. If the bag is not inflated, the mask will not provide the intended oxygen therapy. Choice B is incorrect as the flow rate for a non-rebreather mask is typically set at 10-15 liters per minute to ensure adequate oxygen delivery. Choice C is also incorrect as assessing the patient's ability to breathe independently is important but not the most crucial step before administering the mask. Choice D is incorrect as monitoring arterial blood gas levels is important but not the immediate action needed before administering the mask.
Question 5 of 5
Which assessment finding in a patient with pneumonia requires the nurse to intervene immediately?
Correct Answer: C
Rationale: The correct answer is C because an oxygen saturation of 86% indicates severe hypoxemia, which can lead to tissue damage and organ dysfunction. The nurse should intervene immediately to improve oxygenation. A weak productive cough (Choice A) may indicate impaired airway clearance but does not require immediate intervention. Pleuritic chest pain (Choice B) is common in pneumonia but does not indicate an immediate threat to the patient's life. Coarse crackles in the lower lobes (Choice D) are typical findings in pneumonia but do not necessitate immediate action unless accompanied by severe respiratory distress.
