Nursing Questions on Oxygenation Questions
Question 1 of 5
A patient with COPD is prescribed long-term oxygen therapy. What is the nurse's priority teaching point?
Correct Answer: B
Rationale: The correct answer is B: Do not smoke while using oxygen. Smoking near oxygen can lead to a fire hazard due to the highly flammable nature of oxygen. Smoking should be strictly avoided to prevent any potential accidents. A: Using oxygen continuously is essential for COPD patients, but the priority is to prevent fire hazards by not smoking while using oxygen. C: Increasing the flow rate without healthcare provider guidance can be dangerous and may not address the underlying cause of shortness of breath. D: Removing oxygen during meals is unnecessary and can compromise oxygen delivery, which is crucial for COPD patients.
Question 2 of 5
A patient with COPD is hospitalized for increasing shortness of breath. Which assessment finding requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because an oxygen saturation of 85% on room air indicates severe hypoxemia and requires immediate intervention to prevent organ damage. Oxygen therapy is needed to improve oxygenation. Choice A (Barrel-shaped chest) is a common finding in patients with COPD but does not require immediate intervention. Choice C (Increased anterior-posterior chest diameter) is also a common finding in patients with COPD and does not require immediate intervention. Choice D (Productive cough with yellow sputum) is concerning for a respiratory infection but does not indicate an immediate need for intervention to address the hypoxemia.
Question 3 of 5
A patient with pneumonia develops confusion. What is the nurse's first action?
Correct Answer: A
Rationale: The correct first action is to assess the patient's oxygen saturation (Choice A). Confusion in a patient with pneumonia could indicate hypoxemia, so assessing oxygen saturation helps determine if the confusion is due to inadequate oxygen supply. This step is crucial for immediate intervention. Notifying the healthcare provider (Choice B) can be important but should come after assessing the patient's oxygen saturation. Administering antibiotics (Choice C) is necessary but should not be the first action when a change in mental status occurs. Reassessing vital signs (Choice D) is important but may not provide immediate information on the cause of confusion.
Question 4 of 5
A patient diagnosed with active tuberculosis (TB) is homeless and has a history of alcohol abuse. Which intervention by the nurse will be most effective in ensuring adherence with the treatment regimen?
Correct Answer: C
Rationale: The correct answer is C: Arrange for the patient's friend to administer the medication on schedule. This intervention addresses the patient's social support system, ensuring someone close to them can help with medication adherence. Homelessness and alcohol abuse can make it challenging for the patient to adhere to the treatment regimen independently. Providing support from a trusted friend can increase accountability and motivation. A: Repeating warnings may not address the underlying issues of homelessness and alcohol abuse. B: Giving written instructions may not be effective if the patient struggles with literacy or forgetfulness. D: While providing meals and drug administration at a community center may be helpful, it doesn't address the patient's need for personalized support.
Question 5 of 5
A nurse is caring for a patient who is scheduled for a colonoscopy. What should the nurse do first?
Correct Answer: A
Rationale: The correct answer is A: Administer a laxative. Administering a laxative is the first step before a colonoscopy to ensure the colon is clear for better visualization. High fiber intake (B) may be recommended after the procedure. Stool softeners (C) are used for constipation but not typically prior to a colonoscopy. Encouraging ambulation (D) is beneficial post-procedure but not the first step.
