Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
Which finding suggests a patient is experiencing respiratory acidosis?
Correct Answer: A
Rationale: Respiratory acidosis occurs with a low pH (30) and high PaCO2 (50 mmHg) due to CO2 retention, unlike normal (35-45) or alkalotic values.
Question 2 of 5
A nurse is collecting data from a client who has gastroesophageal reflux disease (GERD) and reports having heartburn every night. Which of the following actions should the nurse identify as a contributing factor to the client’s heartburn?
Correct Answer: B
Rationale: Orange juice is highly acidic and can irritate the esophagus, leading to increased heartburn symptoms. Regular consumption of acidic beverages like orange juice can exacerbate GERD symptoms, making this a likely contributing factor to the client's heartburn.
Question 3 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 4 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 5 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.
