Which backup practice is recommended when GPS is unreliable?

• A. Rely on GPS only
• B. Use a preplanned route, rely on landmarks, and confirm with dispatch
• C. Call the hospital
• D. Ignore dispatch guidance

Answer: (B)

When GPS is unreliable, you want a navigation approach that doesn’t depend on a single source of information. A solid backup combines a preplanned route you’ve studied beforehand with using recognizable landmarks to verify your position, and you confirm directions with dispatch. The preplanned route gives you a dependable path that you can follow even if the GPS signal drops or the screen isn’t updating. Using landmarks—like highway exits, building sides, or distinctive features—helps you confirm you’re on the right street or turning at the correct intersection, keeping you oriented in real time. Confirming with dispatch ensures you have the latest routing instructions, traffic conditions, and any changes to the destination or patient needs, so you’re not acting on outdated information.

Relying on GPS alone can lead to errors if the signal is lost or misinterpreted. Calling the hospital doesn’t address the route itself, and ignoring dispatch guidance bypasses critical updates and safety instructions.
