Medical Code - Emergency Situation

Which "Zone" of an MRI facility contains the actual scanner and the strongest magnetic field?. Zone I. Zone II. Zone III. Zone IV.

When a "Code Blue" (medical emergency) occurs in the MRI room, where should the patient be resuscitated?. Inside the scanner bore to save time. On the floor next to the magnet. In Zone III or a designated safe area outside the scan room. In the computer control room.

Why must emergency responders (Fire, Police, EMS) be screened before entering the MRI room?. To check for their professional ID badges. Because their standard equipment (stretchers, oxygen tanks, tools) is often ferromagnetic and dangerous. To ensure they have the correct insurance paperwork. To make sure they are wearing the correct hospital uniform.

What does the "Emergency Power Off" (EPO) button do?. It immediately turns off the magnetic field. It cuts all incoming electrical power into the scanner's computer and power units. It releases the liquid helium into the room. It unlocks the doors to the entire hospital.

Does the Emergency Power Off (EPO) button stop the magnetic field?. Yes, immediately. No, the magnetic field is "always on" regardless of electrical power. Only if the building's main generator is also turned off. Only if the scanner is not currently taking pictures.

What is a "Quench" (Emergency Magnet Stop)?. A way to cool down the patient if they get too hot. The rapid boil-off of liquid helium collapse the magnetic field in an emergency. A cleaning procedure for the scanner bore. The process of turning off the lights in the MRI suite.

In what specific situation should the "Quench" button be pushed?. If the computer system crashes. If there is a minor electrical fire in the control room. Only if a person is pinned or impaled by a metal object and there is no other way to free them. If the patient is feeling claustrophobic.

What is the primary danger of helium gas escaping into the MRI room during a quench?. It causes the room to become extremely hot. It creates a high risk of explosion. It displaces oxygen, creating a risk of asphyxiation and severe cold burns. It makes the floor too slippery to walk on.

Because helium is lighter than air, where is the safest place to breathe if you are trapped in an MRI room during a quench?. Standing on a chair. As close to the ceiling as possible. Low to the floor. Directly next to the vent pipes.

Who is typically authorized to make the decision to "Quench" the magnet?. The patient’s family members. The arriving Fire Department crew. The MRI Technologist or Radiology Manager. The hospital security guard.
