Applying an improperly sized rigid cervical collar might result in
Correct Answer
A. A too-large collar will hyperextend the neck
Explanation
An improperly sized rigid cervical collar can cause hyperextension of the neck if it is too large. This means that the collar will extend the neck beyond its normal range of motion, potentially causing strain or injury to the neck muscles and ligaments. It is important to ensure that a cervical collar fits properly to provide the necessary support without causing additional harm.
2.
The components of the central nervous system are the
Correct Answer
A. Brain and spinal cord
Explanation
The central nervous system is responsible for coordinating and controlling the body's activities. It consists of the brain and spinal cord, which work together to receive and process information, send signals to different parts of the body, and regulate bodily functions. The brain is the control center, while the spinal cord acts as a pathway for transmitting signals between the brain and the rest of the body. Therefore, the correct answer is brain and spinal cord.
3.
A short spine board is appropriate to use in immobilizing a patient who is
Correct Answer
A. Seated in a vehicle
Explanation
A short spine board is appropriate to use in immobilizing a patient who is seated in a vehicle because it provides stability and support to the spine, preventing any further movement or potential injury during transportation. The short spine board is specifically designed to fit the contours of a seated patient, ensuring proper immobilization and minimizing the risk of exacerbating any spinal injuries.
4.
When using a short spine board to immobilize a patient, the patient's head should be secured
Correct Answer
A. Last, after the body
Explanation
When using a short spine board to immobilize a patient, it is important to secure the patient's head last, after the body has been secured. This is because securing the body first ensures that the spine is properly aligned and immobilized. Once the body is secured, the head can then be immobilized to provide further support and prevent any potential movement or injury to the neck or spine.

Your patient is a 52-year-old unconscious female patient who was the driver in a vehicle struck by a milk delivery truck. She has an open head wound, and bruising to the chest and abdomen. Respiration's are 28 per minute, pulse is 140 per minute. Her skin is cool and clammy. Your choice for extricating this patient is
Correct Answer
C. Rapid extrication
Explanation
Given the patient's condition of being unconscious, having an open head wound, bruising to the chest and abdomen, rapid breathing, high pulse rate, and cool and clammy skin, the best choice for extricating this patient would be rapid extrication. Rapid extrication involves quickly removing the patient from the immediate danger without immobilizing the spine, as it is not indicated in this scenario. Immobilization with a short spine board, full immobilization with a KED, or using a long board only would not be appropriate in this case as they would delay the patient's removal from the dangerous situation.

When log-rolling a patient onto a long spine board, the EMT-B in charge of the move is the person at the
Correct Answer
A. Head
Explanation
When log-rolling a patient onto a long spine board, the EMT-B in charge of the move is positioned at the head of the patient. This is because the head is the most delicate and vulnerable part of the body, and requires careful handling to prevent any further injury to the spine or neck. Being positioned at the head allows the EMT-B to provide proper support and control during the log-rolling maneuver, ensuring the safety and stability of the patient's spine.
7.
Bone fragments, blood clots, vomit or broken teeth are all potential
Correct Answer
D. Airway obstructions
Explanation
Airway obstructions can cause shock as they prevent the flow of oxygen to the lungs and subsequently to the rest of the body. When the airway is blocked, the person may struggle to breathe, leading to a decrease in oxygen levels and an increase in carbon dioxide levels. This can result in a state of shock, where the body's organs and tissues do not receive enough oxygen to function properly. Promptly clearing the airway obstruction is crucial in order to restore proper breathing and prevent further complications.
