Fundamentals of Nursing Oxygenation NCLEX Questions Questions
Question 1 of 5
Which finding indicates a patient is compensating for hypoxia?
Correct Answer: A
Rationale: Tachypnea (rapid breathing) is a compensatory mechanism to increase oxygen intake in hypoxia, unlike bradycardia, hypotension, or lethargy, which suggest decompensation.
Question 2 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 3 of 5
Which intervention prevents hypoxemia during suctioning?
Correct Answer: A
Rationale: Pre-oxygenation increases oxygen reserves, preventing hypoxemia during suctioning, unlike prolonged suction, large catheters, or continuous suction, which can worsen hypoxia.
Question 4 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 5 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.
