In contrast to typical wheeled ambulance stretchers, features of a bariatric stretcher include:

• A. Increased stability from a wider wheelbase.
• B. Two safety rails on both sides of the stretcher.
• C. Weight capacity up to 650 lb.
• D. A collapsible undercarriage.

Answer: (A)

The key idea here is safety through stability. Bariatric stretchers are designed to carry heavier patients, but the main feature that truly sets them apart is a wider wheelbase that increases lateral stability. A wider base distributes weight more effectively and lowers the risk of tipping when the stretcher is moved over uneven surfaces, around corners, or during transfers. This stability is crucial for both patient safety and crew control during transport.

Other features like rails or higher weight ratings can be present on various stretchers, but they don’t define bariatric design in the same way a wider wheelbase does. A collapsible undercarriage isn’t a defining trait of bariatric stretchers.
