Diagnostic and Surgical Procedures
| Question | Answer |
|---|---|
| assessment techniques | sequence of procedures designed to evaluate the health status of a patient |
| auscultation | listening to the heart, bowel, and lungs with or without a stethoscope to assess the presence and quality of sounds |
| inspection | general observation of the patient as a whole, progressing to specific body areas |
| palpation | gentle application of the hands to a specific structure or body area to determine size, consistency, texture, symmetry, and tenderness of underlying structures |
| percussion | tapping a body structure with the hand or fingers to assess consistency and the presence or absence of fluids within the underlying structure |
| endoscopy | visual examination of a body cavity or canal using a specialized light instrument called an endoscope |
| blood chemistry analysis | laboratory test, usually performed on serum, to determine biochemical imbalances, abnormalities, and nutritional conditions |
| complete blood count (CBC) | broad screening test used to evaluate red blood cells, white blood cells, and platelets to determine anemias, infections, and other diseases |
| computed tomography (CT) | imaging technique that rotates an x-ray emitter around the area to be evaluated and measures the intensity of transmitted rays from different angles |
| fluoroscopy | technique in which x-rays are directed through the body to a fluorescent screen that displays internal structures in continuous motion |
| magnetic resonance imaging (MRI) | technique that uses radio waves and a strong magnetic field, rather than an x-ray beam, to produce highly detailed, multiplanar, cross-sectional views of soft tissue |
| nuclear scan | technique in which a radioactive material (radiopharmaceutical) called a tracer is introduced into the body (inhaled, ingested, or injected), and a specialized camera (gramma camera) produces images of organs and structures |
| positron emission tomography (PET) | computed tomography records the positrons (positively charged particles) emitted from a radiopharmaceutical to produce a cross-sectional image of the metabolic activity of body tissues to determine the presence of disease |
| radiography | technique in which x-rays are passed through the body or area and captured on a film to generate an image; also called an x-ray |
| single-photon emission computed tomography (SPECT) | radiological technique that integrate CT and a radioactive material (tracer) injected into the blood stream to visualize blood flow to tissues and organs |
| ultrasonography (US) | high-frequency sound waves (ultrasound) are directed at soft tissue and reflected as "echoes" to produce an image on a monitor of an internal body structure; also called ultrasound, sonography, and echo |
| biopsy (Bx) | removal of a representative tissue sample from a body site for microscopic examination, usually to establish a diagnosis |
| excisional | biopsy in which the entire lesion is removed |
| incisional | biopsy in which only a small sample from the lesion is removed |
| ablation | removal of a body part, pathway, or function by surgery, chemical destruction, electrocautery, freezing, or radio frequency (RF) |
| anastomosis | surgical joining of two ducts, vessels, or bowel segments to allow flow from one to another |
| curettage | scraping of a body cavity with a spoon shaped instrument called a curette |
| electrocauterization | use of an electrically activated instrument to burn and destroy diseased tissue |
| incision and drainage (I&D) | incision made to allow the free flow of fluids and pus from a wound, abscess, or body cavity |
| laser surgery | use of a high-intensity laser beam to remove diseased tissues, to stop bleeding, or for cosmetic purposes |
| revision | surgical procedure used to replace or compensate for a previously implanted device or correct an undesirable result or effect of a previous surgery |
