One practical advantage of ultrasound is its portability, enabling bedside imaging.

• A. Portable
• B. Requires a large room
• C. Radiation-heavy
• D. Slow

Answer: (A)

Portability and bedside imaging are the practical advantages being tested. Modern ultrasound devices are compact, often handheld, and can run on batteries, so they easily move between rooms, clinics, or even into ambulances. Because ultrasound uses non-ionizing sound waves, there’s no need for heavy shielding or dedicated imaging suites, and setup is quick, allowing rapid assessment at the patient’s side. The real-time imaging capability provides immediate feedback, which is crucial in emergencies, critical care, or when transporting a unstable patient would be risky. This flexibility and speed set the bedside imaging advantage apart from modalities that require larger spaces, involve radiation, or are slower.
