NCLEX Oxygenation Practice Questions Questions
Question 1 of 5
A nurse is caring for a client who required 7 L of oxygen to maintain oxygen saturation. Which of the following oxygen delivery devices should the nurse expect to use?
Correct Answer: B
Rationale: In this scenario, the correct answer is B) Nonrebreather mask. The nurse should expect to use a nonrebreather mask because this device can deliver high concentrations of oxygen, up to 90%, which is necessary for a client requiring 7 L of oxygen to maintain oxygen saturation. Nasal cannula (option A) delivers lower concentrations of oxygen and would not be sufficient for this client's needs. Partial-rebreather mask (option C) allows the rebreathing of some exhaled air, resulting in a lower oxygen concentration. Simple face mask (option D) also delivers lower oxygen concentrations compared to a nonrebreather mask. Educationally, understanding the appropriate oxygen delivery devices based on a client's oxygen requirements is crucial for nurses, especially when caring for clients with respiratory issues. This knowledge ensures effective oxygen therapy and optimal patient outcomes. Nurses must be able to assess, select, and administer the appropriate oxygen delivery method based on the client's condition and oxygen needs.
Question 2 of 5
A client with COPD reports difficulty breathing while lying flat. What intervention should the nurse implement?
Correct Answer: B
Rationale: In this scenario, the correct answer is B) Encourage the use of a recliner chair. This intervention helps alleviate difficulty breathing while lying flat in a client with COPD by allowing them to sit in a more upright position, which reduces the pressure on the diaphragm and lungs. Option A) Teach diaphragmatic breathing techniques, while beneficial for COPD management, does not directly address the immediate issue of difficulty breathing while lying flat. Option C) Elevate the head of the bed to 30 degrees is a common intervention for clients with respiratory issues, but a recliner chair provides better support and comfort for clients with COPD experiencing difficulty breathing in a lying position. Option D) Administer bronchodilators before bedtime is not directly related to the positional discomfort experienced by the client, and it may not effectively address the immediate issue of difficulty breathing while lying flat. Educationally, understanding the rationale behind choosing a recliner chair for clients with COPD can help nurses provide appropriate care tailored to the individual's needs, promoting optimal comfort and respiratory function. It is essential for nurses to be knowledgeable about positioning interventions to manage respiratory symptoms effectively in clients with COPD.
Question 3 of 5
A client with tuberculosis is prescribed rifampin. What is the most important teaching point for the nurse to emphasize?
Correct Answer: C
Rationale: The correct answer is C) Do not stop the medication even if symptoms improve. This is the most important teaching point for the nurse to emphasize because rifampin is an antibiotic used to treat tuberculosis, which is a serious infectious disease. It is crucial for the client to complete the full course of treatment to ensure that all the TB bacteria are killed and to prevent the development of drug-resistant strains. Option A) Avoid direct sunlight to prevent photosensitivity is incorrect because rifampin does not typically cause photosensitivity. Option B) Expect orange discoloration of urine and tears is a common side effect of rifampin due to its color, but it is not as important as ensuring completion of the medication. Option D) Avoid foods high in potassium is unrelated to rifampin therapy and is not a significant teaching point for this medication. In an educational context, it is essential for nurses to understand the rationale behind medication teaching to provide comprehensive care to their clients. By emphasizing the importance of completing the full course of rifampin therapy, nurses can help ensure treatment success and prevent the spread of tuberculosis. This teaching point highlights the critical role of patient education in promoting adherence to treatment regimens and improving health outcomes.
Question 4 of 5
The nurse is teaching a client with asthma about avoiding triggers. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: The correct answer is B: "I can sleep with my pet as long as I vacuum regularly." This statement indicates a need for further teaching because pet dander is a common trigger for asthma symptoms. Even with regular vacuuming, the pet dander can still be present in the environment and can exacerbate asthma symptoms. It is important for individuals with asthma to avoid exposure to pet dander to help manage their condition effectively. Option A is correct as individuals with asthma should avoid cleaning products with strong odors as these can trigger asthma symptoms. Strong odors can irritate the airways and lead to breathing difficulties for individuals with asthma. Option C is correct as outdoor exercise during high pollen seasons can expose individuals with asthma to allergens that can trigger asthma symptoms. It is recommended for individuals with asthma to exercise indoors or during times when pollen levels are lower. Option D is correct as using air conditioning can help reduce indoor humidity levels, which can create a more comfortable environment for individuals with asthma. High humidity levels can promote the growth of mold and dust mites, which are common asthma triggers. In an educational context, it is important for nurses to provide detailed and accurate information to clients with asthma to help them effectively manage their condition. Teaching about asthma triggers and how to avoid them is crucial in empowering clients to take control of their health and prevent asthma exacerbations.
Question 5 of 5
The nurse is evaluating the effectiveness of a bronchodilator for a client with COPD. Which finding indicates improvement?
Correct Answer: B
Rationale: In this question, the correct answer is option B) Oxygen saturation improved to 94%. This finding indicates improvement in a client with COPD who is being treated with a bronchodilator. The rationale behind this is that in COPD, impaired gas exchange is a common problem due to airway obstruction and decreased lung function. By improving oxygen saturation, the bronchodilator is effectively helping the client to oxygenate better, which is a critical goal in managing COPD. Option A) Heart rate increased to 100 beats per minute is incorrect because an increased heart rate may indicate tachycardia, which could be a sign of distress or inadequate response to the medication. Option C) Client reports mild dizziness is incorrect as dizziness is not a typical sign of improvement in COPD with bronchodilator therapy. Option D) Respiratory rate increased to 24 breaths per minute is incorrect because an increased respiratory rate may suggest respiratory distress rather than improvement in oxygenation status. Educationally, understanding the expected outcomes of bronchodilator therapy in COPD is crucial for nurses caring for these patients. Monitoring oxygen saturation levels is a key assessment parameter to evaluate the effectiveness of treatment and ensure optimal patient outcomes.
