A nurse is performing a lung assessment on a client. The nurse should understand which information about lung structures?

A) Both lungs are equal in size with varying numbers of lobes: This is incorrect. The right lung is slightly larger than the left lung, as the left lung is somewhat smaller to accommodate the heart. The right lung has three lobes, while the left lung has only two lobes. B) The diaphragm rises in the chest during inspiration: This is incorrect. During inspiration (inhalation), the diaphragm contracts and moves downward to allow the lungs to expand and fill with air. It rises during exhalation as it relaxes and pushes air out of the lungs. C) The left lung has two lobes to make room for the heart: This is correct. The left lung has two lobes (upper and lower) compared to the three lobes of the right lung. The left lung is slightly smaller due to the space the heart occupies on the left side of the chest, allowing for asymmetry between the two lungs. D) The right lung has two lobes to make room for the liver: This is incorrect. The right lung has three lobes, not two. The liver is located lower in the abdomen and does not influence the number of lobes in the right lung. The asymmetry of the lungs is due to the position of the heart on the left side of the chest.
