Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A nurse is preparing a patient for a thoracentesis. What is the priority nursing action?
Correct Answer: B
Rationale: Positioning the patient upright facilitates fluid drainage during thoracentesis and ensures safety, taking priority over monitoring BP, sedation, or checking saturation initially.
Question 2 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 3 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 4 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 5 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.
