Vocabulary (24)

a/pnea: without breathing
Acute: Sudden or short course. Utilization: Contrast with chronic in interviews.
Anterior / posterior: Front surface versus back surface of the body. Utilization: Used in anatomy-based documentation and exam.
Auscultation: Listening with a stethoscope to breath, heart, or bowel sounds. Utilization: Supports airway and circulatory assessment when noise allows.
brady/pnea: slow breathing
Chief complaint: Brief statement of why help was sought, usually in the patient's words. Utilization: Anchors interview and documentation even when later findings broaden the picture.
Chronic: Long-standing condition. Utilization: Impacts baseline function and medications.
Combining vowel: Letter (often o) linking roots for pronunciation. Utilization: Seen in cardi/o and gastro/o.
Diagnosis: Identification of a disease or condition based on findings. Utilization: EMTs often document impressions consistent with scope rather than hospital-grade diagnoses.
Differential diagnosis: List of possible causes considered by clinicians. Utilization: EMTs form field impressions rather than definitive diagnosis.
Eponym: Term named after a person. Utilization: Examples appear throughout anatomy and signs.
History of present illness: Chronologic symptom story including onset, quality, severity, timing, context. Utilization: Guides differential concerns and targeted exam.
Homeostasis: Stable internal balance maintained by body systems. Utilization: Background concept linking pathophysiology chapters ahead.
Inflammation: Local response with redness, heat, swelling, pain, sometimes loss of function. Utilization: Explains suffix patterns such as -itis in diagnostic language.
Medial / lateral: Toward midline versus away from midline. Utilization: Standard directional language for wound description and neuro checks.
Palpation: Assessing texture, temperature, tenderness, or pulses by touch. Utilization: Use gentle-to-firm technique comparing sides when assessing abdomen or pulses.
Pathogen: Organism capable of causing disease. Utilization: Connects terminology of infection to scene safety and reportable exposures.
Prefix: Word beginning that modifies meaning. Utilization: Example: brady- suggests slow.
Prone: Lying face down. Utilization: Important after trauma for spine considerations and special airway situations.
Proximal / distal: Closer to trunk versus farther from trunk along a limb. Utilization: Describes injury locations and pulse checks relative to the torso.
Sign versus symptom: Objective finding versus subjective report. Utilization: Vital signs are signs; nausea described by patient is a symptom.
Suffix: Word ending that often indicates condition or procedure. Utilization: Example: -ectomy removal.
Supine: Lying face up. Utilization: Common transport position; note airway considerations for respiratory distress.
tachy/pnea: rapid breathing
