    Study Notes

    Skeletal System

    • Provides structure, support, and shape to the body.
    • Protects vital organs such as the brain, heart, and lungs.
    • Facilitates movement in conjunction with the muscular system.
    • Stores minerals like calcium and phosphorus and produces blood cells in the bone marrow.
    • Main parts include the axial skeleton (skull, vertebrae, rib cage) and appendicular skeleton (limbs and pelvis).

    Muscular System

    • Gives shape to the body and allows for movement.
    • Contains three muscle types:
      • Voluntary muscles (skeletal): Control body movements consciously.
      • Involuntary muscles (smooth): Function automatically, found in organs like blood vessels and intestines.
      • Cardiac muscle: Exclusive to the heart, responsible for heart contractions.

    Nervous System

    • Controls both voluntary and involuntary body activities.
    • Central nervous system (CNS) comprises the brain and spinal cord, acting as the body’s main control center.
    • Peripheral nervous system (PNS) consists of nerves branching from the CNS to the rest of the body, enabling two-way communication.

    Skin

    • Largest organ of the body; serves as a protective barrier.
    • Essential for infection control through the use of personal protective equipment (PPE) and hygiene practices.
    • Standard precautions include treating all bodily fluids as potentially infectious to prevent disease transmission.

    Practices to Reduce Risk

    • Hand Hygiene: Key method for infection prevention by removing pathogens from hands.
    • Primary Assessment: Identify immediate life-threatening conditions upon arrival at a scene.
    • Secondary Assessment: Conduct a comprehensive head-to-toe examination of the patient for injuries.

    Assessing Level of Consciousness (LOC)

    • Utilize the AVPU scale:
      • Alert: Patient is fully awake and aware.
      • Verbal: Patient responds to verbal stimuli.
      • Pain: Patient reacts to painful stimuli only.
      • Unresponsive: No response to any stimuli, indicating unconsciousness.

    PMS Assessment (Pulse, Motor, Sensory)

    • Pulse: Check for presence or absence of pulse.
    • Motor: Assess ability to move; determine sensation before movement.
    • Sensory: Confirm presence of feeling in touch areas.

    Comprehensive Physical Assessment

    • Conduct a systematic examination of each body part:
      • Head: Inspect for trauma, fluid loss, or discoloration.
      • Eyes: Assess pupil reaction; check for constriction/dilation.
      • Neck: Look for signs of trauma and airway obstruction.

    Triage Procedures

    • Use color-coded tags to classify patients based on their medical needs:
      • RED: Immediate care required.
      • YELLOW: Delayed care, stable but needing attention.
      • GREEN: Minor injuries, can walk.
      • BLACK: Non-salvageable, deceased.
    • Remember RPM mnemonic for assessment: Respiration, Perfusion, Mental status.
