Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
Which lifestyle change most improves oxygenation in a patient with obesity?
Correct Answer: C
Rationale: Weight loss reduces chest wall resistance and improves lung expansion in obesity, enhancing oxygenation, unlike increasing calories, reducing activity, or sleeping supine.
Question 2 of 5
When administering oxygen therapy, what should the nurse prioritize to ensure the safety of the client?
Correct Answer: B
Rationale: Monitoring the client's oxygen saturation levels using a pulse oximeter is crucial to assess the effectiveness of oxygen therapy and ensure the client's oxygen needs are being met adequately.
Question 3 of 5
A client with congestive heart failure (CHF) experiences worsening dyspnea and peripheral edema. What is the primary indication for initiating oxygen therapy in this client?
Correct Answer: D
Rationale: In clients with CHF, the primary indication for oxygen therapy is to improve myocardial oxygenation and relieve symptoms of myocardial ischemia.
Question 4 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 5 of 5
A nurse is caring for a client receiving oxygen therapy through a transtracheal catheter. What is an important nursing consideration for this client?
Correct Answer: C
Rationale: The nurse should closely monitor the oxygen flow rate continuously to ensure proper delivery and prevent complications specific to the transtracheal catheter, such as obstruction or dislodgement.
