Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
Which assessment confirms adequate oxygenation?
Correct Answer: A
Rationale: Pink nail beds indicate good peripheral oxygenation and circulation, unlike cold extremities (poor perfusion), tachypnea (respiratory distress), or confusion (hypoxia).
Question 2 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 3 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 4 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 5 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.
