Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
A nurse is caring for a client with severe hypoxemia and requires precise oxygen titration. Which oxygen delivery system would be most appropriate for this client?
Correct Answer: D
Rationale: High-flow nasal cannula is effective in delivering precise oxygen concentrations and provides consistent oxygenation for clients with severe hypoxemia.
Question 2 of 5
When administering oxygen therapy, which intervention should the nurse prioritize to ensure the delivery of the prescribed oxygen concentration?
Correct Answer: C
Rationale: Continuous monitoring of the client's oxygen saturation allows the nurse to assess the effectiveness of oxygen therapy and ensure the prescribed oxygen concentration is being delivered. It helps in making timely adjustments to the oxygen therapy to maintain adequate oxygenation.
Question 3 of 5
The nurse is assessing a client who is receiving high-flow oxygen therapy via a non-rebreather mask. Which finding requires immediate intervention?
Correct Answer: D
Rationale: A loose fit of the mask on the client's face can result in a significant reduction in the delivery of high-flow oxygen therapy. It is essential to ensure a proper seal and fit of the mask to maximize the effectiveness of oxygen therapy. Immediate intervention is needed to readjust and secure the mask properly.
Question 4 of 5
A nurse plans teaching for a client who has coronary artery disease. Which dietary recommendation is most important?
Correct Answer: A
Rationale: Atherosclerosis is the primary risk factor in the development of coronary artery disease (CAD). Health promotion efforts are aimed at eliminating saturated and trans saturated fatty acids by preparing foods that are baked or broiled in place of frying or stewing in lard and oils.

A nurse administers 12 units lispro insulin at 0700 to a client. Within which time frame must the morning meal be served?
