Chapter 19 : Introduction to the Respiratory System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse is studying for a physiology test over the respiratory system. What should the nurse know about central chemoreceptors in the medulla?
Correct Answer: A
Rationale: Central chemoreceptors in the medulla respond to changes in CO2 levels and hydrogen ion concentrations (pH) in the cerebrospinal fluid. Central chemoreceptors do not respond to changes in the O2 levels in the brain, changes in CO2 levels in the brain, changes in O2 levels, and bicarbonate levels in the cerebrospinal fluid.
Question 5 of 5
What is the difference between respiration and ventilation?
Correct Answer: B
Rationale: Ventilation is the actual movement of air in and out of the respiratory tract. Respiration is the exchange of oxygen and CO2 between atmospheric air and the blood and between the blood and the cells.
