Questions Respiratory System Questions
Question 1 of 5
All of the following pairings are correct (assuming normal person at rest) EXCEPT
Correct Answer: B
Rationale: The correct answer is B: Alveolar ventilation = 7500 ml. Alveolar ventilation is the volume of fresh air that reaches the alveoli per minute. It is calculated by subtracting the dead space ventilation from the tidal volume and then multiplying by the respiratory rate. In a normal person at rest, the average alveolar ventilation is around 4200 ml/min, not 7500 ml/min. Therefore, choice B is incorrect. Choices A, C, and D are correct because tidal volume is typically around 500 ml, pulmonary blood flow is about 5000 ml/min, and functional residual capacity is the volume of gas in the lung after normal expiration.
Question 2 of 5
Blessy, a community health nurse is conducting an educational session with community members regarding tuberculosis. The nurse tells the group that one of the first symptoms associated with tuberculosis is:
Correct Answer: B
Rationale: The correct answer is B: Chest pain. Chest pain can be one of the first symptoms of tuberculosis due to inflammation of the lung tissue or pleura. Dyspnea (A) typically occurs in later stages as the disease progresses. A bloody, productive cough (C) is a common symptom of tuberculosis but may not be one of the first symptoms. Bronchoscopy (D) is a diagnostic procedure and not a symptom of tuberculosis. In summary, chest pain is a common initial symptom due to lung inflammation, while the other choices are either later symptoms or unrelated diagnostic procedures.
Question 3 of 5
A client has experienced pulmonary embolism. A nurse assesses for which symptom, which is most commonly reported?
Correct Answer: C
Rationale: The correct answer is C: Chest pain that occurs suddenly. Pulmonary embolism typically presents with sudden chest pain due to a blockage in the pulmonary arteries. This is a result of a blood clot traveling to the lungs, causing a sharp and stabbing pain. The other options are not typically associated with pulmonary embolism. A hot, flushed feeling (A) is more indicative of a fever or infection, sudden chills and fever (B) may occur in sepsis or the flu, and nausea and vomiting (D) are more commonly seen in gastrointestinal issues.
Question 4 of 5
Which of these assessments made by the nurse indicates that respiratory arrest is imminent in an asthmatic?
Correct Answer: C
Rationale: The correct answer is C: Absence of wheezing. In asthmatics, wheezing is a common sign of airway obstruction. The absence of wheezing indicates a severe obstruction leading to reduced airflow, which can progress to respiratory arrest. Agitation (A) and tachycardia (B) are common signs of distress but do not specifically indicate imminent respiratory arrest. Flaring nares (D) may suggest increased work of breathing, but it is not as specific as the absence of wheezing in predicting imminent respiratory arrest in asthmatics.
Question 5 of 5
Actual exchange of gases in the lungs occurs in the
Correct Answer: B
Rationale: The correct answer is B: alveoli. Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place through diffusion. This process is crucial for oxygenating the blood and removing carbon dioxide. Bronchi (A), bronchioles (C), and trachea (D) are all parts of the respiratory system, but they do not participate directly in gas exchange. Bronchi are the main airways that branch off from the trachea, bronchioles are smaller airways that lead to the alveoli, and the trachea is the main airway that carries air to and from the lungs.
