otoscopes and ophthalmoscopes

The three basic tools to complete a physical examination laboratory tests are the history and practice in the examination and diagnosis /.

A medical history is the most important part of the physical examination, especially during the first visit to your doctor. Includes history habits, lifestyle, family history and symptoms. Many physicians use health risk assessments, detailed questionnaires that provide information about the habits health.

This is an area of the physical examination for a patient can prepare. Following the guidelines for communicating with your doctor submitted earlier in this chapter, you can help your doctor to obtain accurate health profile. This is important because diagnosis usually can be done with only a comprehensive history and practice in the examination.

Hands in the review is the second part of a physical examination. This is a test by touching, looking and listening.

Physicians can feel or palpate the enlarged gland, growths and tumors with procedures such as breast examination, pelvic, digital rectal examination and review of the hernia. Hitting the back and chest allows the physician to see if fluid has accumulated in or around the lungs. Harness for the reflexes of the knee may reveal damage to the nervous system. A stethoscope is listening device of your family doctor and used to listen to the heart, lungs, abdomen, and glands located near the surface of the skin. Possible problems that can be detected with the stethoscope range of a heart murmur to conditions such as poor circulation, infection lung, bowel obstruction and an overactive thyroid gland.

Physicians have access to a range of tools to visually inspect the problems. An ophthalmoscope is used to view the brains for the eye. The first sign of brain diseases is an unhealthy aspect optic nerve. Leaks in blood vessels the eye may be a sign of diabetes or hypertension. The otoscope is used to examine the ear, including tympanic membrane. The sigmoidoscope is used proctoscope and to examine the rectum and colon. The laryngoscope and bronchoscope offer a glimpse into the larynx and bronchi.

The last part of the physical examination included laboratory tests diagnostic, which can vary from a simple urine test for invasive testing dye. The effectiveness of these tests get mixed reviews. Tests for symptoms Specifics may be very valuable in the identification of disabling conditions. They can be as useful as they are not revealed as to what show. This can reassure the patient and physician.

Turning the negative side, many doctors rely too heavily on laboratory tests. Patients often demand or consent to the tests than necessary, sometimes more than good for them. Ten years ago, a quarter of all medical tests contributed little to health. For example, when researchers at the University of California, San Francisco, studied 2,000 patients hospitalized for surgery, they found that 60% of the tests blood regularly ordered were unnecessary. Only 1 in about 450 anomalies revealed, and that was ignored, as are either not noticed or dismissed as insignificant. The researchers concluded that if a complete history is any indication of a medical problem, routine testing is a waste.

Often tests are recommended more for the purpose of protecting the physician against malpractice suits, rather than their diagnostic value. This practice, called medicine defense, paints a bleak picture of the difficulty in making medical decisions for doctors and patients alike. A doctor can tell with 99% certainty of a particular diagnostic test or procedure but the order in any way as protection against liability if it is sued or later. Trials for malpractice are a reality, but increased by 300% in the last 30 years. Almost two thirds of physicians say the threat of liability to influence extra tests. 28 Of course, patients always have the right to refuse a prescribed test. It should be a two-way decision between patient and doctor based on their potential for effective medical intervention.
