Vital Signs: The measurement of basic body functions, including body temperature, pulse rate, respiration rate, and blood pressure, to assess general health.
Inspection: The visual observation of the patient to identify physical abnormalities, skin changes, or behavioral cues.
Palpation: The use of the hands to feel body parts for size, consistency, texture, location, and tenderness.
Auscultation: The process of listening to internal body sounds, typically using a stethoscope, to evaluate the heart, lungs, and digestive system.
| Concept | Description | Perspective |
|---|---|---|
| Symptom | Subjective evidence of disease experienced by the patient (e.g., pain, nausea). | Patient's Feeling |
| Sign | Objective evidence of disease observed by the physician (e.g., rash, high blood pressure). | Doctor's Observation |
| Acute | Conditions that have a rapid onset and a short duration. | Time-limited |
| Chronic | Conditions that persist over a long period, often requiring ongoing management. | Long-term |
Diagnosis vs. Prognosis: A diagnosis identifies the nature of the illness, while a prognosis predicts the likely course and outcome of the disease.
Prescription vs. Over-the-Counter (OTC): Prescriptions require a doctor's authorization for specific medications, whereas OTC drugs can be purchased freely for minor ailments.
Describing Pain: Use specific descriptors such as 'sharp', 'dull', 'throbbing', or 'stabbing' to help the doctor narrow down potential causes. Mentioning the intensity on a scale of 1 to 10 provides a standardized metric for the provider.
Clarification: Patients should always ask for clarification if medical jargon is used. Understanding the 'why' behind a test or treatment improves adherence to the medical plan.
Preparation: Bringing a list of current medications and a timeline of symptoms ensures that no critical information is omitted during the limited time of a consultation.
Withholding Information: Patients sometimes omit details they deem embarrassing or irrelevant, which can lead to an incorrect or delayed diagnosis.
Self-Diagnosis: Relying solely on internet searches can cause unnecessary anxiety or lead to the dismissal of serious symptoms that require professional evaluation.
Confusing Correlation with Causation: Assuming that because two symptoms happen at the same time, one caused the other, which may mislead the clinical investigation.
