Respiratory System Test Questions Questions
Question 1 of 5
If the CO2 concentration in the blood increases, the breathing shall
Correct Answer: A
Rationale: When CO2 concentration in the blood increases, it leads to respiratory acidosis, causing the body to increase breathing rate to expel excess CO2 and restore pH balance. This increase in breathing helps eliminate CO2 through exhalation, thus the correct answer is A. Choice B is incorrect because an increase in CO2 concentration triggers an increase in breathing to remove the excess CO2, not decrease it. Choice C is incorrect because stopping breathing would be life-threatening and is not a physiological response to high CO2 levels. Choice D is incorrect because an increase in CO2 concentration does have an effect on breathing rate to maintain homeostasis.
Question 2 of 5
A nurse is assessing a client who has suffered a nasal fracture. Which assessment would the nurse perform first?
Correct Answer: D
Rationale: The correct answer is D: Airway patency. Ensuring airway patency is the top priority in any client assessment, especially in cases of facial trauma like a nasal fracture. This is because compromised airway can lead to respiratory distress or failure. Assessing airway patency should always be the first step to ensure the client's ability to breathe. Facial pain (A) may be important but does not address immediate life-threatening concerns. Vital signs (B) are important but assessing airway patency takes precedence for client safety. Bone displacement (C) is relevant but does not address the immediate need to maintain airway patency.
Question 3 of 5
The emergency department (ED) manager is reviewing client charts to determine how well the staff perform when treating clients with community-acquired pneumonia. What outcome demonstrates that goals for this client type have been met?
Correct Answer: A
Rationale: The correct answer is A: Antibiotics started before admission. This outcome demonstrates that the staff are meeting the goal for treating clients with community-acquired pneumonia because timely administration of antibiotics is crucial in managing this condition effectively. Starting antibiotics promptly helps to reduce the spread of infection and improve patient outcomes. Blood cultures obtained within 20 minutes (B) is important for diagnosing the specific pathogen causing pneumonia but does not directly reflect the treatment goal achievement. Chest x-ray within 30 minutes (C) is essential for diagnosis but does not indicate treatment success. Pulse oximetry on all clients (D) is important for monitoring oxygen levels but does not directly show if the treatment goal for pneumonia has been met.
