Fundamentals of Nursing Oxygenation Practice Questions Questions
Question 1 of 5
A patient with a chest tube reports sudden dyspnea. What is the priority action?
Correct Answer: A
Rationale: Sudden dyspnea with a chest tube suggests blockage or disconnection. Checking patency ensures proper lung re-expansion and oxygenation, taking priority over pain meds, oxygen increase, or repositioning.
Question 2 of 5
A patient with a history of heart disease reports dyspnea on exertion. What is the likely cause?
Correct Answer: B
Rationale: Left heart failure causes pulmonary congestion, leading to dyspnea on exertion, common in heart disease. Pulmonary embolism, pneumothorax, or bronchitis are less directly tied to exertion.
Question 3 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 4 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 5 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.
