Respiratory System Exam Questions Questions
Question 1 of 5
In mammals ventilation movements of lungs are governed by
Correct Answer: D
Rationale: The correct answer is D: Diaphragm and intercostal muscles. The diaphragm is the primary muscle responsible for inhalation and exhalation by contracting and relaxing, respectively. Intercostal muscles aid in expanding and contracting the rib cage to assist in breathing. The combination of the diaphragm and intercostal muscles working together ensures efficient ventilation of the lungs in mammals. Choices A and B are incorrect because the muscular wall of the lungs and intercostal muscles alone are not solely responsible for regulating ventilation. Choice C is incorrect because the diaphragm alone does not govern ventilation movements without the assistance of the intercostal muscles. Therefore, the correct answer is D as it accurately reflects the coordinated effort of both the diaphragm and intercostal muscles in regulating lung ventilation.
Question 2 of 5
A nurse is assessing a client who is recovering from a lung biopsy. The client's breath sounds are absent. While another nurse calls the Rapid Response Team
Correct Answer: B
Rationale: The correct answer is B, taking a full set of vital signs, as it is crucial in assessing the client's overall condition and detecting any signs of deterioration. Vital signs include blood pressure, heart rate, respiratory rate, and temperature, which provide valuable information about the client's cardiovascular and respiratory status. In this scenario, absent breath sounds indicate potential respiratory compromise, making it essential to monitor vital signs for any signs of respiratory distress or instability. Choice A is incorrect because calling the Rapid Response Team is important, but assessing the client's vital signs should take priority to provide immediate information on the client's condition. Choice C, obtaining pulse oximetry reading, is also important but may not provide a comprehensive assessment of the client's overall condition compared to a full set of vital signs. Choice D, asking about hemoptysis, is not the most urgent action to take in this situation as assessing vital signs would provide more immediate and critical information for the client's management.
Question 3 of 5
A nurse is teaching a client about possible complications and hazards of home oxygen therapy. About which complications doesn't the nurse plan to teach the client?
Correct Answer: D
Rationale: The correct answer is D - Alveolar recruitment. This is because alveolar recruitment is actually a benefit of home oxygen therapy, not a complication. It helps improve oxygenation by opening up collapsed alveoli. A - Absorptive atelectasis is a potential complication where nitrogen is absorbed from the alveoli leading to collapse. B - Combustion is a hazard due to oxygen's flammability. C - Dried mucous membranes is a common complication of oxygen therapy due to the drying effect of oxygen.
Question 4 of 5
A charge nurse is rounding on several older clients on ventilators in the Intensive Care Unit whom the nurse identifies as being at high risk for ventilator-associated pneumonia. To reduce this risk what activity would the nurse delegate to the assistive personnel (AP)?
Correct Answer: C
Rationale: The correct answer is C: Provide oral care every 4 hours. Oral care helps prevent ventilator-associated pneumonia by reducing the risk of oral bacteria being aspirated into the lungs. The AP can assist with oral care under the nurse's supervision. A: Encouraging between-meal snacks does not directly address pneumonia risk. B: Monitoring temperature is important but not specific to ventilator-associated pneumonia prevention. D: Reporting new cough onset is important but does not directly reduce the risk of ventilator-associated pneumonia.
Question 5 of 5
What does a nurse assess postoperatively in a client with a nasal fracture?
Correct Answer: B
Rationale: The correct answer is B. Airway obstruction is a critical concern after a nasal fracture due to potential swelling or displacement of bone fragments. A (allergic reaction) is unrelated. C (extreme sense of smell) is not a concern postoperatively. D (stridor) indicates severe airway compromise but is less common in nasal fractures.
