PHTLS PRACTICE TEST QUESTIONS AND ANSWERS 100% CORRECT
A harmful event that arises from the release of specific forms of physical energy or barriers to
the normal flow of energy Correct Answer: Injury
energy that an object contains when it is in motion Correct Answer: Mechanical Energy
Energy that results from the interaction of a chemical with exposed human tissue Correct
Answer: Chemical Energy
Energy associated with increased temperature and heat Correct Answer: Thermal Energy
Electromagnetic wave that travels in rays and has no physical mass to it. (Example: sunburn)
Correct Answer: Radiation Energy
results from the movement of electrons between two points. it is associated with direct injury and
thermal injury Correct Answer: Electrical Energy
1. When the difficulty of the task suddenly exceeds the individual's performance ability
2. When the individual's performance level falls below the demands of the task
3. When both factors change simultaneously Correct Answer: Uncontrolled release of energy
can produce these three outcomes:
Host (Human)
Agent
Environment Correct Answer: Three factors simulating the epidemiological triangle in relation
to injury
Father of the science of injury prevention Correct Answer: Dr. William J. Haddon Jr.
provides a means to depict graphically the events or actions that increase or decrease the odds
that an injury will occur. It can also be used to identify prevention strategies Correct Answer:
Haddon Matrix
aimed at avoiding the injury before it occurs. This type of prevention activity involves education
programs to help minimize risk-taking behaviors and the use of protective equipment Correct
Answer: Primary Prevention
Actions taken to prevent the progression of an acute injury once it has occurred (Example:
avoiding the occurrence of hypoxia or hypotension after a traumatic brain injury) Correct
Answer: Secondary Prevention
Directed at minimizing death and the long-term disability of an injury after it has occurred.
Correct Answer: Tertiary Prevention
an act of interpersonal or self-directed violence Correct Answer: Intentional Injury
, injuries that were unintended but could have been avoided. Previously referred to as accidents
Correct Answer: Unintentional Injury
The totality of the impact of injury on the health of the public; includes deaths, injury, disability,
and financial considerations Correct Answer: Public Health Impact of Injury
calculated by subtracting age at death from a fixed age of the group under examination... Life
expectancy of a particular group Correct Answer: Years of potential life lost (YPLL)
Bottom: Episodes of injury medically attended
3rd: Emergency department visits
2nd: Hospital discharges
Top: Deaths Correct Answer: Injury Triangle 4 parts
Require little or no action on the part of the individual; sprinkler systems and vehicle air bags
Correct Answer: Passive Strategies for Injury Prevention
Require cooperation of the person being protected; manual seat belts and choosing to wear a
helmet Correct Answer: Active Strategies for Injury Prevention
Education, Enforcement, and Engeneering Correct Answer: 3 E's of Injury Prevention
1. Surveillance
2. Risk Factor Identification
3. Intervention Evaluation
4. Implementation Correct Answer: Public Health Approach--4 step process
process of collecting data within a community Correct Answer: Surveillance
What is necessary or patient improvement or survival Correct Answer: Principle
how the principle is achieved in the time given and by the prehospital care provider available
Correct Answer: Preference
1. The Prehospital Phase
2. The initial (resuscitative) phase in the hospital
3. The stabilization and definitive care phase
4. The long-term resolution and rehabilitation to return the patient to a functional status Correct
Answer: Four phases in the process of caring for patients with acute injuries
A competent adult patient's right to direct his or her own health care free from interference or
undue influence Correct Answer: Autonomy
An ethical principle that obligates the medical provider to not take actions that may harm the
patient or place the patient in harm's way Correct Answer: Nonmaleficence
