Nursing Fundamentals Oxygenation Questions Questions
Question 1 of 5
A client with cystic fibrosis reports difficulty clearing thick mucus. Which intervention should the nurse prioritize?
Correct Answer: C
Rationale: The correct answer is C: Performing chest physiotherapy. This intervention helps mobilize and clear the thick mucus in the client's airways, making it easier for them to breathe. Administering a mucolytic medication (choice A) may help break down mucus but does not address the need for clearance. Encouraging increased fluid intake (choice B) is important for hydration but may not directly address mucus clearance. Providing a low-sodium diet (choice D) is not directly related to improving mucus clearance in cystic fibrosis. Therefore, chest physiotherapy is the priority intervention in this case.
Question 2 of 5
A client with bronchitis is prescribed a nebulizer treatment. What should the nurse include in the teaching?
Correct Answer: A
Rationale: The correct answer is A: Hold your breath for 10 seconds after inhaling the medication. This is because holding the breath allows the medication to reach deep into the lungs for better absorption and effectiveness. Choice B is incorrect as taking deep, fast breaths can cause hyperventilation. Choice C is incorrect as cleaning nebulizer equipment daily should be done with soap and water, not alcohol. Choice D is incorrect as there is no need to avoid drinking fluids after the treatment.
Question 3 of 5
A nurse is preparing a client for pulmonary function testing (PFT). What instruction is most important to provide?
Correct Answer: A
Rationale: The correct answer is A: Avoid bronchodilators for 6 hours before the test. This instruction is crucial because bronchodilators can affect the test results by altering airway function. By avoiding bronchodilators, the client ensures accurate PFT results. Refraining from eating or drinking (B) is not necessary for PFT. Performing light exercise (C) could affect the test results. Wearing tight clothing (D) can impede lung expansion and alter the results.
Question 4 of 5
The nurse is teaching a client with pneumonia about the use of an incentive spirometer. What is the primary benefit of this intervention?
Correct Answer: B
Rationale: The correct answer is B: Prevents alveolar collapse. Incentive spirometry helps to prevent atelectasis by promoting deep breathing and improving lung expansion, preventing alveoli from collapsing. This process keeps the airways open and maintains lung function. Incorrect choices: A: Increases oxygen saturation - While incentive spirometry can help improve oxygenation indirectly by enhancing lung function, its primary benefit is to prevent alveolar collapse. C: Reduces respiratory rate - Incentive spirometry focuses on improving lung expansion and preventing atelectasis, not specifically on reducing respiratory rate. D: Decreases mucus production - Incentive spirometry does not directly impact mucus production; its primary goal is to maintain lung function and prevent complications like atelectasis.
Question 5 of 5
The nurse is teaching a client with asthma about using a peak flow meter. What is the primary purpose of this device?
Correct Answer: C
Rationale: Rationale: 1. A peak flow meter measures peak expiratory flow rate, indicating how well air moves out of the lungs. 2. Early signs of worsening asthma include decreased peak flow readings. 3. By monitoring peak flow, the client can take necessary actions to prevent asthma exacerbations. 4. Choices A and B are incorrect as peak flow meters do not measure lung compliance or directly monitor bronchodilator effectiveness. 5. Choice D is incorrect as peak flow meters are used for ongoing monitoring, not initial diagnosis.
