DHA Emergency Medical Technician - Basic - Features Sample Questions

The average length of the sternum is?

Correct Answer:
17 cm.


the correct average length of the sternum is 17 centimeters. the sternum, commonly referred to as the breastbone, is a flat bone located at the center of the chest. it serves as a critical component of the rib cage and plays a vital role in protecting the heart and lungs.

structurally, the sternum is composed of three major parts: the manubrium, the body (or gladiolus), and the xiphoid process. the manubrium is the upper part of the sternum, connecting to the clavicles (collar bones) and the first two ribs. the body, or gladiolus, is the longest part and connects to the costal cartilages of the ribs. the xiphoid process is the smallest and most variable part, located at the lower end of the sternum.

the sternum's location in the thorax, the central part of the chest, makes it an essential element for the structural integrity and protection of the thoracic cavity. due to its position, the sternum is also involved in the mechanics of breathing.

the measurement of 17 centimeters as the average length of the sternum highlights its size relative to the human body, indicating its substantial role in the human skeletal system. this average can vary slightly among individuals due to factors like age, sex, and physical development.

The decontamination corridor in a hazardous material zone is located:

Correct Answer:
in the warm zone


in hazardous material (hazmat) incidents, controlling and managing the contamination is crucial to ensure safety and prevent further spread of hazardous substances. such incidents are typically managed by dividing the area into different zones: the hot zone, warm zone, and cold zone, each serving distinct functions.

the hot zone, also known as the exclusion zone, is the area immediately surrounding the hazardous material release. this zone poses the highest risk and is where the actual source of contamination is located. only personnel with appropriate protective gear and specific training enter the hot zone to control or stop the release and to initiate preliminary containment.

the cold zone, or clean zone, is where the command and control functions occur and where personnel do not require any protective gear. it is deemed safe from any hazards and is also the area where evacuated individuals and media may be located. this zone houses support functions such as medical triage, recovery, and decontamination command.

the warm zone serves as a transition area and is critically important for safety and operational efficiency during a hazmat incident. it is in this zone that the decontamination corridor is set up. the primary purpose of the decontamination corridor is to prevent the spread of contaminants from the hot zone to the cold zone. personnel and equipment leaving the hot zone must pass through the decontamination corridor where they undergo various decontamination processes to remove or neutralize the hazardous substances.

this corridor typically has two ends: a hot end facing the hot zone and a cold end opening towards the cold zone. decontamination may involve physical cleaning, chemical detoxification, or other methods depending on the nature of the contaminants. the procedures and complexity of decontamination can vary widely but generally include stages such as gross decontamination, secondary decontamination, and sometimes even tertiary steps if the situation demands.

ensuring that the decontamination corridor is located in the warm zone is strategic. it minimizes the risk of spreading contamination to the clean area while providing a buffer and a controlled environment for performing thorough decontamination processes. the location also facilitates easier access to emergency medical services if needed without compromising the safety of the clean zone.

thus, placing the decontamination corridor in the warm zone optimizes the safety and effectiveness of the response to hazardous material incidents. it is a critical component in the structure of hazmat incident management, bridging the most dangerous area and the safe area, thereby protecting both the responders and the public from potential hazards.
