Questions on the Respiratory System Questions
Question 1 of 5
cochlea's have how many fluid filled chamber?
Correct Answer: C
Rationale: The cochlea has 3 fluid-filled chambers: the scala vestibuli, scala media, and scala tympani. These chambers are essential for hearing as they contain different fluids (perilymph and endolymph) that help transmit sound vibrations. Choice A (1 chamber) is incorrect as the cochlea has multiple distinct chambers. Choice B (2 chambers) is incorrect as it does not accurately reflect the anatomical structure of the cochlea. Choice D (4 chambers) is incorrect as the cochlea typically consists of 3 chambers, not 4. Therefore, the correct answer is C (3 chambers) based on the accurate anatomical structure of the cochlea.
Question 2 of 5
The nurse is caring for a patient with advanced emphysema. Which sign isn't manifestations of this disorder?
Correct Answer: D
Rationale: The correct answer is D: Wheezing. Emphysema is characterized by destruction of lung tissue, leading to air trapping and decreased airflow. Wheezing is typically associated with asthma or bronchitis, not emphysema. A: Productive cough is common in emphysema due to increased mucus production. B: Dyspnea (shortness of breath) is a hallmark symptom of emphysema due to impaired gas exchange. C: Barrel chest is a physical finding in emphysema caused by hyperinflation of the lungs.
Question 3 of 5
Which information from a client helps the nurse confirm the previous diagnosis of chronic stable angina?
Correct Answer: D
Rationale: The correct answer is D because chronic stable angina is characterized by chest pain or discomfort that is triggered by physical exertion or emotional stress and relieved by rest or medication. Therefore, the fact that the pain goes away after stopping jogging aligns with the typical pattern of chronic stable angina. A: The pain waking the client up at night is more indicative of unstable angina or a heart attack. B: The level of pain on a scale does not provide conclusive evidence of chronic stable angina. C: Pain worsening over time may suggest unstable angina or a heart attack rather than chronic stable angina.
Question 4 of 5
Your client with pneumonia is being discharged today. Which of the following physical findings would lead the nurse to believe the client is appropriate for discharge. Select all that apply.
Correct Answer: C
Rationale: The correct answer is C: SpO2 98% at rest. This indicates adequate oxygenation, a crucial aspect of recovery from pneumonia. A: Decreased tactile fremitus suggests consolidation, indicating ongoing infection. B: Increased fatigue suggests continued weakness. D: A respiratory rate of 30 breaths/minute is elevated and indicates respiratory distress, not readiness for discharge.
Question 5 of 5
Regarding the lung
Correct Answer: D
Rationale: The correct answer is D because all of the statements are true. A: The human lung contains approximately 300 million alveoli, which are essential for gas exchange. B: Terminal bronchioles are the smallest airways without alveoli, connecting the bronchioles to the alveoli. C: Anatomic dead space refers to the volume of air in the respiratory system that does not participate in gas exchange and is approximately 150 ml. Therefore, since all statements are accurate, the correct answer is D.
