Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A patient with a history of smoking is at risk for which oxygenation issue?
Correct Answer: A
Rationale: Smoking is a primary cause of chronic bronchitis, a COPD type impairing oxygenation, more directly than heart failure, pneumothorax, or pulmonary edema.
Question 2 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 3 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 4 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.
Question 5 of 5
A nurse is providing oxygen therapy to a client using a face mask. What is an important nursing consideration for this client?
Correct Answer: D
Rationale: When using a face mask for oxygen therapy, the nurse should assess the client's skin for any signs of irritation or breakdown due to prolonged mask use. It is important to ensure proper mask fit and periodically assess the skin integrity to prevent pressure ulcers or skin breakdown.
