Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A patient with chest pain and hypoxia is suspected of having which condition?
Correct Answer: A
Rationale: Myocardial infarction can cause chest pain and hypoxia due to reduced cardiac output and oxygenation, more acutely than pneumonia, asthma, or pleurisy.
Question 2 of 5
A nurse is reinforcing teaching for a client who has a duodenal ulcer and a new prescription for sucralfate. The client asks the nurse how sucralfate works. Which of the following statements should the nurse make?
Correct Answer: A
Rationale: Sucralfate works by forming a protective barrier over the ulcer site. It adheres to the ulcer, shielding it from the harmful effects of gastric acid, pepsin, and bile salts. This protection allows the ulcer to heal by preventing further irritation and damage.
Question 3 of 5
A client with severe hypoxemia requires oxygen therapy. What is the appropriate delivery method for this client?
Correct Answer: D
Rationale: A non-rebreather mask is the most suitable delivery method for a client with severe hypoxemia, as it provides the highest concentration of oxygen (up to 95%) by utilizing a reservoir bag and one-way valves to prevent the rebreathing of exhaled air.
Question 4 of 5
A client with pneumonia exhibits signs of respiratory distress and decreased oxygen saturation. What is the primary indication for initiating oxygen therapy in this client?
Correct Answer: C
Rationale: In a client with pneumonia, the primary indication for oxygen therapy is to improve oxygen delivery to tissues and alleviate hypoxia.
Question 5 of 5
A client with acute respiratory distress syndrome (ARDS) requires high levels of positive end-expiratory pressure (PEEP). Which oxygen delivery system would be most effective in providing the necessary PEEP?
Correct Answer: C
Rationale: CPAP mask provides positive pressure throughout the respiratory cycle, including expiration, and is effective in delivering the necessary PEEP in clients with ARDS.
