Chapter 19 : Introduction to the Respiratory System Questions
Question 1 of 5
What would the instructor tell the students purulent fluid indicates?
Correct Answer: B
Rationale: A small amount of fluid lies between the visceral and parietal pleurae. When excess fluid or air accumulates, the physician aspirates it from the pleural space by inserting a needle into the chest wall. This procedure, called thoracentesis, is performed with local anesthesia. Thoracentesis also may be used to obtain a sample of pleural fluid or a biopsy specimen from the pleural wall for diagnostic purposes such as a culture, sensitivity, or microscopic examination. Purulent fluid is the recommended diagnosis for infection. Serous fluid may be associated with cancer, inflammatory conditions, or heart failure.
Question 2 of 5
The client has just had an invasive procedure to assess the respiratory system. What does the nurse know should be assessed on this client?
Correct Answer: C
Rationale: After invasive procedures, the nurse must carefully check for signs of respiratory distress and blood-streaked sputum. Masses in the pleural space are a condition that affects fremitus. General examination of overall health and condition includes assessing the consciousness of a client.
Question 3 of 5
The nurse working in the radiology clinic is assisting with a pulmonary angiography. The nurse knows that when monitoring clients after a pulmonary angiography, what should the physician be notified about?
Correct Answer: C
Rationale: When monitoring clients after a pulmonary angiography, nurses must notify the physician about diminished or absent distal pulses, cool skin temperature in the affected limb, and poor capillary refill. Absent distal pulses may indicate damage to the artery or a clot. When the contrast medium is infused, the client will sense a warm, flushed feeling.
Question 4 of 5
An 18-month-old child is brought to the emergency department by parents who explain that their child swallowed a watch battery. Radiologic studies show that the battery is in the lungs. Which area of lung is the battery most likely to be in?
Correct Answer: A
Rationale: Aspiration of foreign objects is more likely in the right main stem bronchus and right upper lung. The right mainstem bronchus is slightly higher and more vertical than the left, which is why foreign articles are often aspirated here first.
Question 5 of 5
What happens to the diaphragm during inspiration?
Correct Answer: B
Rationale: During inspiration, the diaphragm contracts and flattens, which expands the thoracic cage and increases the thoracic cavity.
