Oxygenation Nursing Practice Questions Questions
Question 1 of 5
The nurse is teaching a client with tuberculosis about the importance of medication adherence. What is the most critical point to emphasize?
Correct Answer: A
Rationale: Rationale: A: Completing the full course of medication is crucial to prevent drug resistance and fully eradicate the bacteria. B: Taking medication only when symptoms worsen can lead to treatment failure and spread of drug-resistant strains. C: Avoiding direct sunlight is not directly related to medication adherence in tuberculosis treatment. D: Consuming a high-fat diet does not improve drug absorption and is not necessary for treatment success.
Question 2 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 3 of 5
A patient hospitalized with chronic obstructive pulmonary disease (COPD) is being discharged home on O2 therapy. Which instruction should the nurse include in the discharge teaching?
Correct Answer: C
Rationale: The correct answer is C because O2 therapy can indeed improve a COPD patient's prognosis and quality of life by providing supplemental oxygen to help with breathing. Increasing O2 flow without healthcare provider guidance (B) can be dangerous. Travel is possible with portable O2 devices (A). O2 is stored in small tanks or concentrators, not large metal tanks lasting 4-6 hours (D).
Question 4 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 5 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.
