malfeasance

commits an act not their responsibility to perform ex: straighten out a fractured bone

misfeasance

commits an act which is their responsibility, but does so incorrectly ex: does not do full job and sends out a player without full assesment

reciprocal inhibition

contract the muscle opposite the tight muscle against resistance; cause a reciprocal inhibition of the tight muscle leading to muscle lengthening

flexion-decreasing an angle extension-increasing an angle

shearing force

forces that moves across the parallel design of the fibers

referred pain

is perceived at a location remote from the site of the tissues actually causing the pain

normal healthy tissue after a brief warm up

diastolic pressure

occurs when the ventricles are relaxed;between beats

overuse injuries classification stage 2:

pain during activity, does not restrict performance

predisposes an individual to stress fractures

a type II epiphyseal injury is described as:

separation of the spiphysis and a small portion of the metaphysis

bone is worst resisting

shear forces

specific adaption to imposed demands (SAID) principle

the body responds to a given demand with a specific and predictable adaption

Nonfeasance

the failure to perform a legal duty ex: knows a kid is hurt and allows them to keep playing and then the kid fully blows ACL

the basis for rating the severity of a contusion is:

the impairment of joint ROM

tendon is 2X stronger than

the muscle it serves

the strength of scar tissue in the maturation phase is determined by:

which of the following require activation of the emergency plan, including activation of EMS? (select all that apply)

-suspected shock -respiratory failure -excessive bleeding

when tissues sustain a force, what are the primary factors that determine the occurrence of an injury? (select all that apply)

-the magnitude of the force -the material properties of the involved tissues

which of the following are physiological effects of cold? (select all that apply)

-vasoconstriction -decreased capillary permeability -decreased muscle spasm

4 elements of negligence

1) duty of care 2) Breach of that duty 3) harm occurred because of the breach of duty 4) resulting harm was a direct cause of the breach of duty

what are the three primary mechanical forces that produce injury

1)compression 2)tensile 3)sheering

strains and sprains that produce moderate discomfort, tenderness, swelling, ecchymosis, detectable joint instability, and/or muscle weakness are categorized as:

3rd degree

TRUE or FALSE if an individual reports an injury that is chronic in nature, the coach should perform an assessment. It is the responsibility of the coach to assess a chronic injury and determine the next course of action

FALSE

TRUE or FALSE: the only responsibility of the coach with regard to athletic equipment is to ensure that the equipment is approved by the appropriate agency

FALSE

static stetching

GTO override impulses from the muscle spindles

TRUE of FALSE an initial step in the on-site assessment of an acute injury is the removal of any equipment that may interfere with the evaluation process

FALSE

TRUE of FALSE in managing an open wound, the first step in the process is to control the bleeding through the application of indirect pressure

FALSE

TRUE of FALSE movements in the sagittal place include flexion, extension, abduction, and adduction

FALSE

TRUE or FALSE immobilization of an acute soft tissue injury for 72 hours post-injury will optimize the healing process

FALSE

TRUE or FALSE a coach developed an efficient and effective emergency plan for their school. the coach transfers to a new school. Implementing the same plan that was used at the previous institution should be sufficient.

FALSE

TRUE or FALSE anaphylaxis is hypersensitive reaction to an allergen. It is rarely a fatal condition

FALSE

TRUE or FALSE in completing an on-site assessment of an acute injury, the coach must ensure that their actions are consistent with their standard of care

TRUE

TRUE or FALSE in the management of an unconscious athlete, the evaluator should assume that a neck injury is present

TRUE

TRUE or FALSE the posterior branches are afferent (sensory) nerves that transmit information from sensory receptors in the skin, tendons, ligaments, and muscles to the central nervous system

TRUE

TRUE or FALSE the proliferative phase of healing begins when the size of the hematoma is sufficiently reduced to permit room for new tissue growth

TRUE

systolic pressure

The blood pressure generated by the heart during contraction. (pumping blood)
