Diagnostic and Surgical Procedures Flashcards
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 patient as a whole, progressing to specific body areas
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 lighted instrument called an endoscope.
blood chemistry analysis
lab 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 hightly detailed, multiplanar, cross-sectional views of soft tissues
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 (gamma camera) produces images of organs and structures
positron emission tomography
computed tomography records the positrons (positively charged particles) emitted from a radiopharmaceutical to produce a cross-sectional image of the metabolic activity of the 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 x-ray
single-photon emission computed tomography
radiological technique that integrates compound tomography (CT) and a radioactive material (tracer) injected into the bloodstream 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
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 of the lesion is removed
ablation
removal of a body part, pathway, or function by surgery, chemical destruction, electrocautery, freezing, or radio frequency.
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
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 light 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.
allergy skin test
any test in which a suspected allergen or sensitizer is applied to or injected into the skin to determine the patient’s sensitivity to it
intradermal
skin test that identifies suspected allergens by subcutaneously injecting small amounts of extracts of the suspected allergens and observing the skin for a subsequent reaction
patch
skin test that identifies allergic contact dermatitis by applying a suspected allergen to a patch, which is then taped on the skin, usually the forearm, and observing the area 24 hours later for an allergic response
scratch
skin test that identifies suspected allergens by placing a small quantity of the suspected allergen on a lightly scratched area of the skin; also called puncture test or prick test
culture and sensitivity
lab test to determine the presence of pathogens in patients with suspected wound infections and identify the appropriate drug therapy to which the organism responds
frozen section (FS)
ultrathin slice of tissue from a frozen specimen for immediate pathological examination
needle
removal of a small tissue sample for examination using a hollow needle, usually attached to a syringe
punch
removal of a small core of tissue using a hollow punch
shave
removal of elevated lesions using a surgical blade
Mohs
procedure that involves progressive removal and examination of layers of cancer-containing skin until only cancer-free tissue remains; also called micrographic surgery
