Oxygenation Nursing Practice Questions Questions
Question 1 of 5
The nurse knows that a myocardial infarction is an occlusion of what blood vessel?
Correct Answer: C
Rationale: The correct answer is C: Coronary artery. A myocardial infarction is caused by a blockage in the coronary arteries, leading to inadequate blood supply to the heart muscle. This can result in damage to the heart tissue. The pulmonary artery (A) carries deoxygenated blood from the heart to the lungs, not to the heart muscle. The ascending aorta (B) is the large artery that carries oxygenated blood away from the heart, not directly supplying the heart muscle. The carotid artery (D) supplies blood to the brain, not the heart muscle.
Question 2 of 5
A nurse is caring for a client who has a chest tube. Which of the following findings should the nurse report to the provider?
Correct Answer: B
Rationale: The correct answer is B: Drainage of 80 mL of fluid in the past hour. This finding indicates excessive drainage, which could be a sign of hemorrhage or other complications requiring immediate medical attention. A: Intermittent bubbling in the water seal chamber is expected and indicates proper functioning of the chest tube system. C: Tidaling in the water seal chamber with respiration is a normal finding that indicates the system is functioning correctly. D: Fluctuation in the drainage tubing with breathing is also a normal finding that shows the chest tube is working properly. In summary, choice B is the correct answer as it signals a potentially serious issue, while the other choices are normal findings associated with a functioning chest tube system.
Question 3 of 5
The nurse is reviewing ABG results for a client with acute respiratory failure. Which finding requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because the ABG results show respiratory acidosis (low pH) with hypoxemia (low PaO2) and hypercapnia (high PaCO2), indicating acute respiratory failure. Immediate intervention is needed to improve oxygenation and ventilation to prevent further deterioration. Choices A, C, and D do not show significant abnormalities requiring immediate intervention. A has slightly low PaO2 but normal pH and PaCO2. C has normal ABG values. D shows respiratory alkalosis with normal oxygenation and ventilation.
Question 4 of 5
The nurse is caring for a client with pneumonia. Which intervention is most effective in preventing hospital-acquired pneumonia?
Correct Answer: C
Rationale: Rationale for Correct Answer C: Performing frequent oral care is the most effective intervention in preventing hospital-acquired pneumonia. This is because oral care helps to reduce the risk of oral bacteria being aspirated into the lungs, which can lead to pneumonia. By keeping the mouth clean and free of harmful bacteria, the risk of pneumonia is significantly reduced. Summary of Incorrect Choices: A: Administering antibiotics as prescribed may be necessary for treating pneumonia, but it does not directly prevent hospital-acquired pneumonia. B: Encouraging ambulation several times daily is important for preventing complications like deep vein thrombosis in hospitalized patients, but it does not directly prevent pneumonia. D: Providing a high-calorie, high-protein diet is important for overall nutrition and immune function, but it does not directly prevent hospital-acquired pneumonia.
Question 5 of 5
A nurse is caring for a client with pulmonary edema. Which assessment finding requires immediate action?
Correct Answer: A
Rationale: The correct answer is A: Productive cough with pink, frothy sputum. This finding indicates potential pulmonary edema, a life-threatening condition. Pink, frothy sputum suggests blood-tinged fluid in the lungs, requiring immediate intervention. Options B and C are concerning but can be managed with timely interventions. Option D is within the normal range for respiratory rate and does not indicate immediate danger.
