What might be examined if a patient is suspected of having atelectasis?

When a patient is suspected of having atelectasis, lung function is the primary focus of examination. Atelectasis refers to the collapse or partial collapse of a lung or a section (lobe) of a lung, which can significantly impact the patient's ability to breathe effectively and can lead to decreased oxygenation of the blood.

Assessing lung function typically involves various diagnostic tests, such as spirometry or imaging techniques like chest X-rays or CT scans. These evaluations help to determine the extent of lung involvement, identify the underlying cause (such as blockage or compression), and guide the appropriate treatment.

Other options like kidney function, heart rhythm, and abdominal sounds do not directly pertain to the diagnosis or examination of atelectasis. While they may be assessed in a comprehensive evaluation of a patient’s overall health, they are not relevant to this specific lung condition.
