Fundamentals of Nursing Oxygenation NCLEX Questions Questions
Question 1 of 5
Which oxygen delivery system is best for a patient requiring precise FiO2?
Correct Answer: C
Rationale: The Venturi mask delivers a precise fraction of inspired oxygen (FiO2) via adjustable settings, ideal for conditions like COPD, unlike nasal cannula, simple mask, or non-rebreather.
Question 2 of 5
The nurse is teaching a patient recently diagnosed with type 1 diabetes mellitus (DM) about the disease. What information should the nurse include?
Correct Answer: A
Rationale: Type 1 diabetes is an autoimmune condition where the body's immune system attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the pancreas produces little to no insulin, which is essential for regulating blood glucose levels.
Question 3 of 5
A patient with type 1 DM expresses concern about developing retinopathy due to a chronic disease. How should the nurse reply?
Correct Answer: C
Rationale: Good control of blood glucose levels and blood pressure is essential in reducing the risk of diabetic retinopathy and its progression. Research has shown that maintaining tight glycemic control and managing hypertension can significantly decrease the likelihood and severity of retinopathy in patients with diabetes.
Question 4 of 5
A client with chronic obstructive pulmonary disease (COPD) presents with severe dyspnea and hypoxemia. What is the appropriate indication for initiating oxygen therapy in this client?
Correct Answer: D
Rationale: Oxygen therapy is indicated in clients with COPD to prevent complications of hypoxia, such as tissue damage and respiratory failure.
Question 5 of 5
A nurse is providing oxygen therapy to a client with pneumonia. Which oxygen delivery system would be most appropriate for this client?
Correct Answer: C
Rationale: A non-rebreather mask is most appropriate for a client with pneumonia requiring high oxygen concentrations due to severe hypoxemia. It delivers up to 95% oxygen, ensuring adequate oxygenation while the underlying infection is treated. (Note: This question lacks a direct answer in the document; rationale is generated based on context from Question 1 and general medical knowledge.)
