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.
