Oxygenation Nursing Practice Questions Questions
Question 1 of 5
The nurse is preparing to administer a bronchodilator to a client with asthma. What assessment is most important before administration?
Correct Answer: C
Rationale: The correct answer is C: Measuring the client's heart rate. Before administering a bronchodilator to a client with asthma, it is crucial to assess the heart rate as bronchodilators can cause tachycardia as a side effect. Monitoring the heart rate will help determine the client's baseline status and identify any potential adverse reactions. Checking the respiratory rate (choice A) is important but not the most critical assessment before administering a bronchodilator. Assessing lung sounds (choice B) is relevant but does not directly address the potential cardiovascular side effects of the medication. Monitoring oxygen saturation levels (choice D) is essential but does not specifically focus on the cardiovascular response to the bronchodilator.
Question 2 of 5
The nurse is caring for a client with a tracheostomy. Which finding requires immediate intervention?
Correct Answer: B
Rationale: The correct answer is B because oxygen saturation of 88% indicates hypoxemia, which requires immediate intervention to prevent complications. Hypoxemia can lead to tissue damage and organ dysfunction. Oxygen therapy is needed to improve oxygen saturation. Choices A, C, and D are not as urgent. Mucus in the tracheostomy tube can be suctioned, mild redness can be monitored for infection, and effective coughing indicates airway patency.
Question 3 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 4 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 5 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.
