Western Medicine Diagnosis Introduction
BASIC PHYSICAL DIAGNOSIS
A road map to clinical proficiency in three critical areas:
◦The health history
◦The physical examination
◦The written record
General data -Name, gender, age, phone, occupation, marital status
🞂Date and Time of History.
The date is always important. You are strongly advised to routinely document the time you evaluate the patient, especially in urgent, emergent, or hospital settings.
History Taking
Symptom:
Symptoms are subjective and experienced only by the patient.
For example, pain, fatigue, shortness of breath, and a rash are all symptoms. They’re the feelings, sensations, and changes in health that a person notices.
Signs:
A sign is objective evidence of disease that another person can detect, often a healthcare professional. For example, a doctor might observe a rash, a swollen joint, or a fever when examining a patient.
THE HEALTH HISTORY: STRUCTURE AND PURPOSES
🞂Chief Complaint(s)
🞂Present Illness
🞂Past History
🞂Family History,
🞂Personal and Social History
🞂Review of Systems
Chief complaint:
The one or more symptoms or concerns causing the patient to seek care
🞂Make every attempt to quote the patient’s own words.
🞂For example, “My stomach hurts and I feel awful.” Sometimes patients have no overt complaints, in which case you should report their goals instead. For example, “I have come for my regular checkup”; or “I’ve been admitted for a thorough evaluation of my heart.”
History of present illness
- Amplifies the Chief Complaint, describes how each symptom developed
Includes patient’s thoughts and feelings about the illness.
- This section of the history is a complete, clear, and chronologic account of the problems prompting the patient to seek care.
- The narrative should include the onset of the problem, the setting in which it has developed, its manifestations, and any treatments.
- The principal symptoms should be well-characterized, with descriptions of
- (1) location
- (2) quality
- (3) quantity(amount) or severity
- (4) timing, including onset, duration, and frequency
- (5) the setting in which they occur
- (6) factors that have aggravated or relieved the symptoms
- (7) associated manifestations
Past History
Childhood Illnesses:
- such as measles, rubella风疹 , mumps, whooping cough, chicken pox, rheumatic fever, scarlet fever, and polio are included in the Past History.
- Also included are any chronic childhood illnesses.
Adult Illnesses in each of four areas:
- Medical (such as diabetes, hypertension, hepatitis, asthma, HIV disease, information about hospitalizations);
- Surgical (include dates, indications, and types of operations);
- Obstetric/gynecologic (relate obstetric history, menstrual history, birth control, and sexual function);
- Psychiatric (include dates, diagnoses, hospitalizations, and treatments).
Family History
- Outline or diagram the age and health, or age and cause of death, of each immediate relative, including parents, grandparents, sib-lings(sisters, brothers), children, and grandchildren.
- Review each of the following conditions and record if they are present or absent in the family: hypertension, coronary artery disease, stroke, diabetes, thyroid or renal disease, cancer (specify type), arthritis, tuberculosis, asthma or lung disease, headache, seizure disorder, mental illness, suicide, alcohol or drug addiction, and allergies, as well as symptoms reported by the patient.
Personal and Social History
- occupation;
- home situation and significant others; sources of stress, both recent and long-term; important life experiences, job history, financial situation, and retirement;
- lifestyle habits that promote health or create risk such as exercise and diet, dietary supplements or restrictions, and use of coffee, tea, and other caffeine-containing beverages.
- You may want to include any alternative health care practices.
Review of Systems
- Think about asking series of questions going from “head to toe.”
- Start with a fairly general question as you address each of the different systems. This focuses the patient’s attention and allows you to shift to more specific questions about systems that may be of concern. Examples of starting questions are: “How are your ears and hearing?” “How about your lungs and breathing?” “Any trouble with your heart?” “How is your digestion?” “How about your bowels?”
- Keep your technique flexible.

Reflexes. Including biceps, triceps, brachioradialis, patellar, Achilles deep tendon reflexes.
RECORDING YOUR FINDINGS
Now you are ready to review an actual written record documenting a patient’s history and physical findings,
Your written record organizes the information from the history and physical examination and should clearly communicate the patient’s clinical issues to all members of the health care team.
Physical examination technique
- Inspection
- Palpation
- Light palpation
- Deep palpation
- Percussion
- direct percussion
- indirect percussion
- Auscultation (stethophone/stethoscope)

Vital sign:
BLOOD PRESSURE: blood pressure is considered to be between 90/60mmHg and 120/80mmHg. high blood pressure is considered to be 140/90mmHg or higher. low blood pressure is considered to be below 90/60mmHg.
HEART RATE AND RHYTHM:
The radial pulse is commonly used to assess the heart rate. If the rhythm is regular and the rate seems normal, count the rate for 15 seconds and multiply by 4.
Normally, adults heart rate is 60 - 100.
RESPIRATORY RATE AND RHYTHM:
Observe the rate, rhythm, depth, and effort of breathing.
Count the number of respirations in 1 minute either by visual inspection or by subtly listening over the patient’s trachea with your stethoscope during your examination of the head and neck or chest.
Normally, adults take 14 to 20 breaths a minute in a quiet regular pattern.
TEMPERATURE:
The average oral temperature, at 37°C (98.6°F), In the early morning hours it may fall as low as 35.8°C (96.4°F), and in the late afternoon or evening it may rise as high as 37.3°C (99.1°F).
Rectal temperatures are higher than oral temperatures by an average of 0.4 to 0.5°C (0.7 to 0.9°F).
Axillary temperatures are lower than oral temperatures by approximately 1 degree, but take 5 to 10 minutes to register and are generally considered less accurate than other measurements.)
