The three basic tools for completing a bodily exam are healing history, hands-on examination, and diagnostic/laboratory tests.

A healing history is the most foremost part of the bodily examination, especially during the first visit with your physician. It includes a history of habits, lifestyle, house history, and symptoms. Many physicians use health-risk appraisals, detailed questionnaires that furnish information about health habits.


This is one area of the bodily exam for which a inpatient can prepare. By following the guidelines for communicating with your doctor presented earlier in this chapter, you can help your doctor obtain an literal, health profile. This is foremost because a diagnosis can regularly be made with only a standard history and hands-on examination.

The hands-on exam is the second part of the bodily examination. It consists of an exam by touching, looking, and listening.

Physicians can feel or palpate for enlarged glands, growths, and tumors with procedures, such as the breast examination, pelvic examination, rectal examination, and hernia examination. Thumping the back and chest lets the doctor know whether any fluid has built up in or nearby the lungs. Tapping a knee for reflexes may quote nervous ideas damage. A stethoscope is the physician's basic listening gismo and is used to listen to the heart, lungs, abdomen, and glands located near the exterior of the skin. Potential problems that can be detected with the stethoscope range from a heart murmur to such conditions as poor circulation, lung infection, intestinal blockage, and an overactive thyroid gland.

Physicians have passage to a amount of instruments to visually examine for problems. An ophthalmoscope is used to view the brain by seeing into the eye. The first sign of some brain diseases is an unhealthy seeing optic nerve. Leakage in the blood vessels of the eye may be a sign of diabetes or hypertension. An otoscope is used to examine the ear, particularly the tympanic membrane. The proctoscope and sigmoidoscope are used to examine the rectum and colon. The laryngoscope and bronchoscope furnish a look at the larynx and bronchial tubes.

The last part of the bodily exam includes diagnostic laboratory tests, which may vary from a simple urinalysis to invasive dye tests. The effectiveness of these tests receives mixed reviews. Tests conducted for definite symptoms may be invaluable in pinpointing disabling conditions. They may be just as indispensable for what they do not quote as they are for what they do reveal. This can be reassuring to the inpatient and physician.

On the negative side, many physicians rely too heavily on laboratory tests. Patients often question or acquiesce to more tests than necessary, sometimes more than is good for them. Ten years ago, one fourth of all healing tests contributed miniature to health. For example, when researchers at the University of California, San Francisco, studied 2000 patients hospitalized for surgery, they found that 60% of the blood tests routinely ordered were unnecessary. Only 1 in about 450 revealed abnormalities, and they were ignored because they were whether not noticed or dismissed as not significant. The researchers fulfilled, that if a standard history turns up no hint of a healing problem, disposition testing is a waste.

Many times tests are recommended more for the purpose of protecting the doctor against healing malpractice suits, rather than for their diagnostic value. This practice, which is called defensive medicine, paints a sobering picture of the mystery in development healing decisions for doctors and patients alike. A doctor may know with 99% certainty a particular diagnosis but order a test or course any way as safety against liability should he or she be sued later. Malpractice suits are a reality; they have increased 300% in the past 30 years. Practically two thirds of physicians say that the threat of liability influences them to order extra tests. 28 Of course, patients always have the right to decline a prescribed test. It should be a two-way decision between inpatient and doctor that is based on its Potential for an efficient healing intervention.
