Oxygenation Nursing Practice Questions Questions
Question 1 of 5
A patient with acute dyspnea is scheduled for a spiral computed tomography (CT) scan. Which information obtained by the nurse is a priority to communicate to the health care provider before the CT?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Allergy to shellfish is critical as iodinated contrast used in CT scans may cause an allergic reaction. 2. Respiratory rate of 30 is concerning but may be due to dyspnea, which is the reason for the CT scan. 3. Apical pulse of 104 is slightly elevated but not an immediate concern for the CT scan. 4. O2 saturation of 90% is low, but the patient may need oxygen during the CT scan, not necessarily a contraindication. Summary: Communicating the allergy to shellfish is essential as it impacts the safety of using contrast during the CT scan. The other vital signs may be addressed during or after the scan without posing an immediate risk.
Question 2 of 5
The nurse is caring for a patient with newly diagnosed tuberculosis (TB). What is the most important instruction to include in the teaching plan?
Correct Answer: B
Rationale: The correct answer is B: Take medications exactly as prescribed for the entire course. This is crucial in treating TB to prevent drug resistance and ensure the infection is fully eradicated. Choice A is not necessary as TB is not transmitted through the air. Choice C is not needed unless the patient is in close contact with others. Choice D is not specific to TB treatment and may cause unnecessary social isolation.
Question 3 of 5
The nurse observes continuous bubbling in the water-seal chamber of a patient's chest tube. What should the nurse do?
Correct Answer: B
Rationale: The correct answer is B: Check the system for air leaks. Continuous bubbling in the water-seal chamber indicates an air leak in the system. Checking for air leaks is important to prevent complications like pneumothorax. Clamping the chest tube (A) can cause tension pneumothorax. Adding more sterile water (C) can disrupt the system's balance. Notifying the healthcare provider (D) should be done after checking for air leaks.
Question 4 of 5
Which patient statement indicates a need for additional teaching about oxygen therapy?
Correct Answer: B
Rationale: The correct answer is B because increasing oxygen flow rate without healthcare provider approval can be dangerous, leading to oxygen toxicity. Choice A shows good understanding of smoking risks with oxygen therapy. Choice C demonstrates awareness of equipment maintenance. Choice D indicates compliance with the provider's instructions. However, B is the only statement that suggests a potential misunderstanding of oxygen therapy management.
Question 5 of 5
A patient with pneumonia reports sharp chest pain that worsens with deep breathing. What should the nurse do first?
Correct Answer: B
Rationale: The correct answer is B because auscultating the lungs for breath sounds will help assess the severity and distribution of the pneumonia. This step is vital in determining the appropriate treatment and intervention. Administering pain reliever (Choice A) may mask symptoms and delay proper assessment. Encouraging deep breaths (Choice C) can exacerbate the pain. Placing the patient in a high Fowler's position (Choice D) may provide comfort but does not address the immediate need for assessment.
