Final answer:
An ultrasound transducer is typically used for a spleen exam, utilizing ultrasonography to generate real-time images of the spleen's anatomy and physiology.
Step-by-step explanation:
In a spleen exam, an ultrasound transducer is typically used. Ultrasonography is an imaging technique that uses high-frequency sound waves to generate an echo signal, which is then converted into a real-time image of the anatomy and physiology of the spleen. This non-invasive method allows for the visualization of the spleen's structure and any abnormalities that might be present.
