Q

What are bones?

A

hard but flexible living structures that provide support for the body and protection of vital organs made from dense connective tissue providing body’s framework strong to provide support and protection for internal organs and flexible to withstand stress store salts and metabolic materials providing site for production of red blood cells and are very vascular with blood loss from the bone itself. Bones become more brittle with less calcium stored in them

Q

What are breaks or fractures?

A

result in swelling of soft tissue and formation of a blood clot in area of fracture due to loss of blood from bone and surrounding tissue causing death to cells at injury site with nearby cells replacing and forming surrounding fracture and making new bone taking weeks or months must be immobilized to properly heal with possibility of more soft tissue damage tkaing longer to heal resulting in possible permanent disability

What is an angulated fracture?

A

fracture in which broken bone segments are at an angle to each other. bent at angle one chance to realign fracture and only going to do it if it isnt going to break skin and if multiple people are going to hold depending on standing procedurs if you meet resistance you stop, if you lose CMS you stop, if so painful you stop.
If dont have CMS because of angle want to attempt dont mess with joint injury. Put in pillow splint and give pain meds . do knee like you would do a joint

Q

What is open extremity injury?

A

an extremity injury in which the skin has been broken or torn through from the inside by an injured bone or from the outside by something that has caused a penetrating wound with associated injury to the bone with increased likelihood of contamination and infection
expose wound, clean surfance, control bleeding, cut away contaminated clothing. Dont walk patient to ambulance and now bleeding under control isnt because of increased heart rate. Stab or gunshot think along potential line. Stab wounds are considered serious if in a vital area of body as how long and serrated or not to tlel you more about what type of internal injuries. Is the offender male or female. Men stab up women stab dwon with less damage.

Q

What is compartment syndrome?

A

injury caused when tissues such as blood vessels and nerves are constricted within a space as from swelling or from a tight dressing or cast and need to remove pressure or may lose limb may complain of pressure with reduced CMs and may feel hard
severe swelling in extremity as a result of fracture. Causing bleeding and swellin gin extremity and can no longer prefuse tissues against pressure going to immobilize area, document it especially if loss of CMS to area. Blood flow to area is lost and limb may be lost

Q

What appears in a musculoskeletal injury?

A

six P’s (pain or tenderness, pallor (pale skin or poor cap refill), paresthesia (sensation of pins and needles), pulses diminished or absent in injured extremity, paralysis or inability to move, pressure
Pain and tenderness- pain when part moved will hold it still or guard to minimize pain ask him to point examine injured part to see others
Deformity or angulation- force of trauma causes bones to fracture and become deformed, or angulated out of anatomic position comparing to uninjured side
Grating or crepitus- a grating sensation or sound made when fractured bone ends rub together can be painful to patient.
Swelling- bones break and soft tissue is torn, bleeding causes swelling increasing the proportions of a deformity and things can restrict this tissue cutting them off.
Bruising- ecchymosis large black-and-blue discoloration of the skin, indicates an underlying injury hours or days old with obvious ones needing splinting.
Exposed bone ends- protruding through skin indicate fracture more gruesome appearance ore temptation don’t kill.
Joints locked into position- locking into different positions need to be splinted as found
Nerve and blood-vessel compromise- examine for pulses, sensation, and movement distal to the injury must do before and after splinting

62
Q

What is herniation?

A

pushing of a portion of the brain downward toward the foramen magnum as a result of increased intracranial pressure resulting in decorticate or decerbrate psoturing flexing arms and rwrists and extending legs and feet

63
Q

What is the sequence of bleeding on the brain?

A

patient falls and hits head with possible brief loss of consciousness, altered mental status 10 minutes later as hematoma begins to place pressure on hemispheres, altered mental status worsens responding only to loud verbal stimulus by moaning increasing blood pressure, unresponsive high bp and pulse is dropping with unequal or nonreactive pupils, irregular respiration, decerebrate and seizure with death. Subdural can results with symptoms 12-24 hours later with possible bruising behind ear or black eyes under both eyes as late signs with irrational behavior temperature increased multiple image vision impaired hearing or ringing projectile vomiting equilibrium problems as a major sign but doesn’t cause shock. Put on a loose dressing and let blood drain out keep them resting stabilize objects

64
Q

What are facial injuries?

A

bone fragments may lodge in back of pharynx and cause airway obstruction such as blood, blood clots, dislodged teeth, or a separated palate possibly blocking airway. Perhaps indicating also a brain injury, may have difficulty speaking

Q

What is the glasgow coma scale?

A

eye opening with spontaneous eye opening means patient opens eyes without you having to do anything if closed have them try to open with normal voice, shoot, use painful stimuli, if more than minor eye injuries don’t do. Verbal response- oriented (AVPU), confused (cannot answer previous questions but speaks in phrases and sentences), inappropriate words (requirng physical stimulaton and curses), incomprehensible sounds (mumbling, moaning or groaning), no verbal response (to painful and vocal sounds) motor response (obeys commands and instructions, localized pain (attempt to remove hand from firm pressure to nails), withdraws after painful stimulatoin (elbow flexes moves slowly appearance of stiffness), posturing after painful stimulation (legs and arms extend and stiffness), no motor response.

69
Q

What are spinal cord injuries?

A

primary injuries as a result in direct force have irreversible outcomes with nervous tissue not healing and permanent nervous transmission lacking such as paralysis. Secondary injuries- cause same and even more harm with hypoxia, shock swelling of the cord and hypoglycemia leading to devastating spinal cord damage. With all injuries having a serious trauma to any part of body including extremities potentially causing it. Usually caused by forcing movement of spine beyond its normal range of motion moving bone into area where spinal cord would be with flexion and extension injuries such as whiplash injury in rear end collision. Axial loading- shallow-water diving injury. With the cervical and lumbar are more susceptible to injury with osteoporosis also making you susceptible as well as ligament laxity such as in pregnant patients and down syndrome as does ankylosing spondylosis causing spine to fuse together being more vulnerable

70
Q

What are mechanisms of high risk for spinal injuries?

A

falls from greater than 1 meter or down more than 5 stairs, axial loading (compression injuries) such as those that occur in diving injuries, high-speed motor-vehicle crashes, especially with rollover or ejection of the patient, motorized recreational vehicle (ATV) crashes, bicycle

paralysis of extremities, changes in neurological function such as loss of sensation or motor function (pins and needles), pain with movement, tenderness along midline spine, impaired breathing slight movement of abdomen with little or no movement of chest or tight muscle spasms) neurogenic shock

73
Q

What is neurogenic shock?

A

a state of shock (hypoperfusion_ caused by nerve paralysis that sometimes develops from spinal cord injuries. Cervical neck 3-5 are crucial (phrenic nerve controlling diaphragm is in C4. Injury to sympathetic in thoracic or lumbar spine affecting heart rate, vascular tone, and dilation of bronchiolar smooth muscle

74
Q

What is spinal motion restriction?
