Nursing Fundamentals Oxygenation Questions Questions
Question 1 of 5
A nurse is preparing to administer oxygen to a client with a tracheostomy. Which equipment is most appropriate?
Correct Answer: C
Rationale: The correct answer is C: Tracheostomy collar. This equipment is most appropriate for a client with a tracheostomy because it is specifically designed to deliver oxygen directly to the tracheostomy site. The tracheostomy collar ensures proper oxygen delivery without interfering with the tracheostomy tube. A: Nasal cannula is not appropriate for a client with a tracheostomy as it delivers oxygen through the nose, bypassing the tracheostomy site. B: Non-rebreather mask is not ideal for a tracheostomy client as it may not deliver oxygen effectively to the tracheostomy site. D: Venturi mask may not be suitable for a tracheostomy client as it may not provide the precise oxygen concentration required.
Question 2 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 3 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 4 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.
Question 5 of 5
The nurse is teaching a client with asthma about using a spacer with an inhaler. What is the primary benefit of using a spacer?
Correct Answer: A
Rationale: The correct answer is A because a spacer helps deliver medication more effectively to the lungs by slowing down the speed of the medication particles, allowing for better penetration into the lungs. This improves drug delivery and reduces the risk of side effects. Choices B, C, and D are incorrect because using a spacer does not eliminate the need for deep breaths, prevent oral thrush, or reduce the frequency of inhaler use.
