A physical examination is an evaluation of the body and its functions using inspection, palpation (feeling with the hands), percussion (tapping with the fingers), and auscultation (listening). A complete health assessment also includes gathering information about a person's medical history and lifestyle, doing laboratory tests, and screening for disease.
Description
A complete physical examination usually starts at the head and proceeds all the way to the toes. However, the exact procedure will vary according to the needs of the patient and the preferences of the examiner. An average examination takes about 30 minutes. The cost of the examination will depend on the charge for the professional's time and any tests that are done. Most health plans cover routine physical examinations including some tests.
The examination
First, the examiner will observe the patient's appearance, general health, and behavior, along with measuring height and weight. The vital signs—including pulse, breathing rate, body temperature, and blood pressure— are recorded.
With the patient sitting up, the following systems are reviewed:
Skin. The exposed areas of the skin are observed; the size and shape of any lesions are noted.
Head. The hair, scalp, skull, and face are examined.
Eyes. The external structures are observed. The internal structures can be observed using an ophthalmoscope (a lighted instrument) in a darkened room.
Ears. The external structures are inspected. A lighted instrument called an otoscope may be used to inspect internal structures.
Nose and sinuses. The external nose is examined. The nasal mucosa and internal structures can be observed with the use of a penlight and a nasal speculum.
Mouth and pharynx. The lips, gums, teeth, roof of the mouth, tongue, and pharynx are inspected.
Neck. The lymph nodes on both sides of the neck and the thyroid gland are palpated (examined by feeling with the fingers).
Back. The spine and muscles of the back are palpated and checked for tenderness. The upper back, where the lungs are located, is palpated on the right and left sides and a stethoscope is used to listen for breath sounds.
Breasts and armpits. A woman's breasts are inspected with the arms relaxed and then raised. In both men and women, the lymph nodes in the armpits are felt with the examiner's hands.While the patient is still sitting, movement of the joints in the hands, arms, shoulders, neck, and jaw can be checked.
Then while the patient is lying down on the examining table, the examination includes:
Breasts. The breasts are palpated and inspected for lumps.
Front of chest and lungs. The area is inspected with the fingers, using palpation and percussion. A stethoscope is used to listen to the internal breath sounds.
The head should be slightly raised for:
Heart. A stethoscope is used to listen to the heart's rate and rhythm. The blood vessels in the neck are observed and palpated.
The patient should lie flat for:
Abdomen. Light and deep palpation is used on the abdomen to feel the outlines of internal organs including the liver, spleen, kidneys, and aorta, a large blood vessel.
Rectum and anus. With the patient lying on the left side, the outside areas are observed. An internal digital examination (using a finger), is usually done if the patient is over 40 years old. In men, the prostate gland is also palpated.
Reproductive organs. The external sex organs are inspected and the area is examined for hernias. In men, the scrotum is palpated. In women, a pelvic examination is done using a speculum and a Papamnicolaou test (Pap test) may be taken.
Legs. With the patient lying flat, the legs are inspected for swelling, and pulses in the knee, thigh, and foot area are found. The groin area is palpated for the presence of lymph nodes. The joints and muscles are observed.
Musculoskeletel system. With the patient standing, the straightness of the spine and the alignment of the legs and feet is noted.
Blood vessels. The presence of any abnormally enlarged veins (varicose), usually in the legs, is noted.
In addition to evaluating the patient's alertness and mental ability during the initial conversation, additional inspection of the nervous system may be indicated:
Neurologic screen. The patient's ability to take a few steps, hop, and do deep knee bends is observed. The strength of the hand grip is felt. With the patient sitting down, the reflexes in the knees and feet can be tested with a small hammer. The sense of touch in the hands and feet can be evaluated by testing reaction to pain and vibration.
Sometimes additional time is spent examining the 12 nerves in the head (cranial) that are connected directly to the brain. They control the sense of smell, strength of muscles in the head, reflexes in the eye, facial movements, gag reflex, and muscles in the jaw. General muscle tone and coordination, and the reaction of the abdominal area to stimulants like pain, temperature, and touch would also be evaluated.
Who Performs the Procedure and Where Is It Performed?
A physical examination is best performed by a trained physician. Other health care professionals such as physician assistants and nurse practitioners have similar but limited training. Examinations are usually performed in professional medical offices or hospitals. Occasionally, they may be performed in private homes or in the field.
Questions to Ask the Doctor
What are my results, both normal and abnormal?
What has changed since the last physical examination?
What do you recommend as a result of the findings of this physical examination?
When do you want to repeat the physical examination?
Definition
A physical examination is the evaluation of a body to determine its state of health. The techniques of inspection include palpation (feeling with the hands and/or fingers), percussion (tapping with the fingers), auscultation (listening), and smell. A complete health assessment also includes gathering information about a person's medical history and lifestyle, conducting laboratory tests, and screening for disease. These elements constitute the data on which a diagnosis is made and a plan of treatment is developed.
Purpose
The term annual physical examination has been replaced in most health care circles by periodic health examination. The frequency with which it is conducted depends on factors such as the age, gender, and the presence of risk factors for disease in the person being examined. Health-care professionals often use guidelines that have been developed by organizations such as the United States Preventative Services Task Force. Organizations such as the American Cancer Society or American Heart Association, which promote detection and prevention of specific diseases, generally recommend more intensive or frequent examinations, or suggest that examinations be focused on particular organ systems of the body.
Comprehensive physical examinations provide opportunities for health care professionals to obtain baseline information about individuals that may be useful in the future. They also allow health care providers to establish relationships before problems occur. Physical examinations are appropriate times to answer questions and teach good health practices. Detecting and addressing problems in their early stages can have beneficial long-term results.
Every person should have periodic physical examinations. These occur frequently (monthly at first) in infants and gradually reach a frequency of once per year for adolescents and adults.

The Examination
Before examiners question the patient, they will observe a person's overall appearance, general health, and behavior. Measurements of height and weight are made. Vital signs such as pulse, breathing rate, body temperature, and blood pressure are recorded.
With the person being examined in a sitting position, the following systems are reviewed:
Skin. The exposed areas of the skin are observed; the size and shape of any lesions are noted.
Head. The hair, scalp, skull, and face are examined.
Eyes. The external structures are observed. The internal structures can be observed using an ophthalmoscope (a lighted instrument) in a darkened room.
Ears. The external structures are inspected. A lighted instrument called an otoscope may be used to inspect internal structures.
Nose and sinuses. The external nose is examined. The nasal mucosa and internal structures can be observed with the use of a penlight and a nasal speculum.
Mouth and pharynx. The lips, gums, teeth, roof of the mouth, tongue, and pharynx are inspected.
Back. The spine and muscles of the back are palpated and checked for tenderness. The upper back, where the lungs are located, is palpated on the right and left sides and a stethoscope is used to listen for breath sounds.
Breasts and armpits. A woman's breasts are inspected with the arms relaxed and then raised. In both men and women, the lymph nodes in the armpits are felt with the examiner's hands. While the person is still sitting, movement of the joints in the hands, arms, shoulders, neck, and jaw can be checked.
While the person is lying down on the examining table, the examination includes:
Breasts. The breasts are palpated and inspected for masses.
Front of chest and lungs. The area is inspected with the fingers, using palpation and percussion. A stethoscope is used to listen to internal breath sounds.
The head should be slightly raised to examine:
Heart. A stethoscope is used to listen to the heart's rate and rhythm. The blood vessels in the neck are observed and palpated.
The person being examined should lie flat for an examination of the:
Abdomen. Light and deep palpation is used on the abdomen to feel the outlines of internal organs, including the liver, spleen, kidneys, and aorta, a large blood vessel.
Rectum and anus. With the person lying on the left side, the outside areas are observed. An internal digital examination (using a gloved finger), is usually done for persons over 40 years old. In men, the prostate gland is also palpated.
Reproductive organs. The external sex organs are inspected and the area is examined for hernias. In men, the scrotum and testicles are palpated. In women, a pelvic examination is completed using a speculum and a sample for a Papanicolaou test (Pap test) may be taken.
Legs. While lying flat, the legs are inspected for swelling, and pulses in the knee, thigh, and foot area are found. The groin area is palpated for the presence of lymph nodes. The joints and muscles are observed.
Musculoskeletal system. With the person standing, the straightness of the spine and the alignment of the legs and feet is noted.
Blood vessels. The presence of any abnormally enlarged veins (varicose), usually in the legs, is noted.
In addition to evaluating a person's alertness and mental ability during the initial conversation, inspection of the nervous system may include:
Neurologic screen. The person's ability to take a few steps, hop, and do deep knee bends is observed. The strength of the handgrip is felt. While sitting in an upright position, the reflexes in the knees and feet can be tested with a small hammer. The sense of touch in the hands and feet can be evaluated by testing reaction to pain and vibration.
The 12 nerves in the head (cranial) that are connected directly to the brain. They control the senses of smell and taste, strength of muscles in the head, reflexes in the eye, facial movements, gag reflex, vision, hearing, and muscles in the jaw. General muscle tone and coordination, and the reaction of the abdominal area to stimulants like pain, temperature, and touch may also be evaluated.
Diagnosis/Preparation
The individual being examined should be comfortable and treated with respect throughout the examination. As the examination continues, examiners should explain what they are doing and share any relevant findings. Using language appropriate to the person being examined improves the effectiveness of communications and ultimately fosters better relations between examiners and examinees.
Before visiting a health care professional, individuals should write down important facts and dates about their own medical history, as well as those of family members. There should be a complete listing of all medications and their dosages. This list should include over-the-counter preparations, vitamins, and herbal supplements. Some people bring their bottles of medications with them. Any questions or concerns about medications should be written down.
Before the physical examination begins, the bladder should be emptied. A urine specimen is usually collected in a small container at this time. The urine is tested for the presence of glucose (sugar), protein, and blood cells. For some blood tests, individuals may be told ahead of time not to eat or drink for 12 hours prior to the test.
Individuals being examined usually remove all clothing and put on a loose-fitting hospital gown. An additional sheet is provided to keep persons covered and comfortable during the examination.
Aftercare
Once a physical examination has been completed, the person being examined and the examiner should review what laboratory tests have been ordered, why they have been selected, and how and with whom the results will be shared. A health professional should discuss any recommendations for treatment and follow-up visits. Special instructions should be put in writing. This is also an opportunity for persons to ask any remaining questions about their own health concerns.
Risks
There are virtually no risks associated with a physical examination. Complications with the process of a physical examination are unusual. Occasionally, a useful piece of information or data may be overlooked. More commonly, results of associated laboratory tests compel physicians to recheck an individual or reexamine portions of the body already reviewed. In a sense, complications may arise from the findings of a physical examination. These usually trigger further investigations or initiate treatment. They are really more beneficial than negative, as they often begin a process of treatment and recovery.
Normal Results
Normal results of a physical examination correspond to the healthy appearance and normal functioning of the body. For example, appropriate reflexes will be present, no suspicious lumps or lesions will be found, and vital signs will be normal.
Abnormal results of a physical examination include any findings that indicate the presence of a disorder, disease, or underlying condition. For example, the presence of lumps or lesions, fever, muscle weakness or lack of tone, poor reflex response, heart arrhythmia, or swelling of lymph nodes will indicate possible health problems.

1. Direct physical inspection of an object. It is necessary, for example, to do a physical examination of bridge structures at periodic intervals to ensure that they are structurally sound and not presenting a public hazard.
2. Medical examination performed on people, called a physical.
Physical examination or clinical examination is the process by which a health care provider investigates the body of a patient for
signs of disease. It generally follows the taking of the
medical history — an account of the symptoms as
experienced by the patient. Together with the medical history, the physical examination aids in determining the correct
diagnosis and devising the treatment plan. This data then becomes part of the medical record.
Although providers have varying approaches as to the sequence of body parts, a systematic examination generally starts at the
head and finishes at the extremities. After the main
organ systems have been investigated by inspection, palpation, percussion and auscultation, specific tests may follow (such as a neurological
investigation, orthopedic examination) or specific tests when a particular disease is
suspected (e.g. eliciting Trousseau's sign in hypocalcemia).
With the clues obtained during the history and physical examination the healthcare provider can now formulate a
differential diagnosis, a list of potential causes of the symptoms. Specific
diagnostic tests (or occasionally empirical therapy) generally confirm the cause, or shed light
on other, previously overlooked, causes.
Whilst the format of examination as listed below is largely as taught and expected of students, a specialist will focus on
their particular field and the nature of the problem described by the patient. Hence a cardiologist will not in routine practice
undertake neurological parts of the examination other than noting that the patient is able to use all four limbs on entering the
consultation room and during the consultation become aware of their hearing, eyesight and speech. Likewise an Orthopaedic surgeon
will examine the affected joint, but may only briefly check the heart sounds and chest to ensure that there is not likely to be
any contraindication to surgery raised by the anaesthetist. Non-specialists generally
examine the genitals only upon request of the patient.
A complete physical examination includes evaluation of general patient appearance and specific organ systems. It is recorded
in the medical record in a standard layout which facilitates others later reading the
notes. In practice the Vital signs of Temperature
examination, Pulse and Blood pressure are usually
measured first.
The main reason for checking body temperature is to solicit any signs of systemic infection or inflammation in the presence of a
fever (temp > 101.4 F or sustained temp > 100.4 F). Other causes of elevated temperature
include hyperthermia. Temperature depression (hypothermia) also needs to be evaluated. It is also noteworthy to review the trend of the patient's
temperature. A patient with a fever of 101 F does not necessarily indicate an ominous sign if his previous temperature has been
higher.
The blood pressure is recorded as two readings, a high systolic pressure which is
the maximal contraction of the heart and the lower diastolic or resting pressure. Usually the
blood pressure is taken in the right arm unless there is some damage to the arm. The difference between the systolic and
diastolic pressure is called the pulse pressure. The measurement of these pressures is
now usually done with an aneroid or electronic sphygmomanometer. The classic measurement device is a mercury sphygmomanometer, using a column of mercury measured off in millimeters. In the United States and UK, the common form is millimeters of mercury, whilst elsewhere
SI units of pressure are used. There is no natural 'normal' value for blood pressure, but rather a
range of values that on increasing are associated with increased risks. The guideline acceptable reading also takes into account
other co-factors for disease. Elevated blood pressure hypertension therefore is variously
defined when the systolic number is persistently over 140-160 mmHg. Low blood pressure is hypotension. Blood pressures are also taken at other portions of the extremities. These pressures are called
segmental blood pressures and are used to evaluate blockage or arterial occlusion in a limb (see Ankle brachial pressure index).
The pulse is the physical expansion of the artery. Its rate is usually measured either at the wrist or the ankle and is
recorded as beats per minute. The pulse commonly is taken is the radial artery at the
wrist. Sometimes the pulse cannot be taken at the wrist and is taken at the elbow (brachial
artery), at the neck against the carotid artery (carotid pulse), behind the knee (popliteal artery), or in the foot
dorsalis pedis or posterior tibial
arteries. The pulse rate can also be measured by listening directly to the heartbeat
using a stethoscope. The pulse varies with age. A newborn or
infant can have a heart rate of about 130-150 beats per minute. A toddler's heart will beat about 100-120 times per minute, an older child's heartbeat is around 90-110 beats per minute, adolescents around 80-100
beats per minute, and adults pulse rate is anywhere between 50 and 80 beats per minute. comment on pulse Rate 60-90 Rhythm
regular-irregular force=systolic tension=diastolic volume=difference between the systolic & diastolic equality on both sides

Respiratory rate
Varies with age, but the normal reference range is 16-20 breaths/minute.
Basic biometrics
Height
Height is the anthropometriclongitudinal growth
of an individual. A statiometer is the device used to measure height although often a
height stick is more frequently used for vertical
measurement of adults or children older than 2. The patient is asked to stand barefoot. Height
declines during the day because of compression of the intervertebral discs. Children
under age 2 are measured lying horizontally.
Weight
Weight is the anthropometric mass of an individual. A
scale is used to measure weight.
Body mass index or BMI is used to calculate the relationship between healthy height
and weight and obesity or being overweight or underweight.
Medical professionals generally prefer to use the SI unit of kilograms, and many medical
facilities have ready-reckoner conversion charts available for professionals to use, when patients describe their weight in
non-SI units. (In the US, pounds and ounces are common,
while in the UK stones and pounds are frequently
used; in most other countries the metric system predominates.)
Pain
Because of the importance of pain to the overall wellness of the patient,
subjective measurement is considered to be a vital sign. Clinically pain is measured using
a FACES scale which is a series of faces from '0' (no pain at all showing a normal happy face) to '5' (the worst pain ever
experienced by the patient). There is also an analog scale from '0' to maximum '10'. It is important to allow patients to make
their own choices on a pain scale. Physicians and health care workers frequently understate patient pain.[citation needed]
Structure of the written examination record
General appearance
Obvious apparent features as the patient enters the consulting room and in the course of taking the history (e.g. mobility
problem or deafness)
