Respiratory System NCLEX Questions Questions
Question 1 of 5
Mammalian lungs have numerous alveoli for
Correct Answer: D
Rationale: The correct answer is D because alveoli increase the surface area for gaseous diffusion, facilitating efficient exchange of oxygen and carbon dioxide in the lungs. Alveoli are tiny air sacs where gas exchange occurs. Option A is incorrect as alveoli do not affect the volume of inspired air. Option B is incorrect as alveoli do not play a role in maintaining lung shape. Option C is incorrect as alveoli do not increase muscles in the lungs for elasticity. Therefore, the primary function of alveoli is to increase surface area for gaseous diffusion, making option D the correct choice.
Question 2 of 5
The charge nurse on a medical unit is preparing to admit several "clients" who have possible pandemic flu during a preparedness drill. What action by the nurse is best?
Correct Answer: B
Rationale: The correct answer is B because in a pandemic flu scenario, it is crucial to inquire about recent travel history to identify potential exposure risks. This information can help determine if the "clients" have been in high-risk areas or in contact with infected individuals. This step is essential for implementing appropriate infection control measures and preventing the spread of the virus. Choice A is incorrect because Contact Precautions are not typically used for airborne infections like the flu. Choice C is incorrect as it discriminates against pregnant caregivers without any evidence-based rationale. Choice D is incorrect because enhanced Droplet Precautions are more suitable for diseases spread through respiratory droplets, not necessarily for pandemic flu with potential airborne transmission.
Question 3 of 5
Which of the following nursing activities is most important when a client comes back from a respiratory test if they have respiratory problems?
Correct Answer: B
Rationale: The correct answer is B. Assessing the airway is critical immediately after a respiratory test, especially if the client has pre-existing respiratory issues. A (rest) is secondary until stability is confirmed. C and D involve education, which is important but not urgent compared to ensuring airway patency.
Question 4 of 5
You are supervising a student nurse who is performing tracheostomy care for a client. For which action should you intervene?
Correct Answer: A
Rationale: The correct answer is A. Suctioning prior to tracheostomy care is incorrect because it increases the risk of introducing infection. Removing old dressings and cleaning secretions (B), removing and cleaning the inner cannula (C), and replacing the inner cannula and cleaning the stoma site (D) are standard steps in tracheostomy care.
