chpt 4 diagnostic and surgical procedures

Question 1

auscultation

Answer 1

listening to the heart, bowel, and lungs with a stethoscope to access the presence and quality of sounds

Question 2

inspection

Answer 2

general observation of a patient as a whole, progressing to specific body areas

Question 3

palpation

Answer 3

gentle application of the hands to specific structure or body area to determine size, consistency, texture, symmetry, tenderness of underlying structures

Question 4

percussion

Answer 4

tapping a body structure with the hand or fingers to assess consistency and the presence or absence of fluids within the underlying structure

Question 5

endoscopy

Answer 5

visual examination of a body cavity or canal using a specialized lighted instrument called an endoscope

Question 6

blood chemistry analysis

Answer 6

lab tests usually performed on serum, to determine biochemical imbalances, abnormalities, and nutritional conditions

Question 7

complete blood count

Answer 7

cbc
broad screening test used to evaluate red blood cells, white blood cells, and platelets to determine anemias, infections, and other diseases

Question 8

computed tomography

Answer 8

imaging technique that rotates an x-ray emitter around the area to be evaluated and measure the intensity of transmitted rays from different angles

Question 9

flouroscopy

Answer 9

technique in which x-rays are directed through the body to a flourescent screen that displays internal structures in continuous motion (contrast dye)

Question 10

magnetic resonance imaging

Answer 10

technique that uses radio waves and strong magnetic field, rather than an x-ray beam, to produce highly detailed, multiplanar, cross-sectional views of soft tissue

Question 11

nuclear scan

Answer 11

technique in which a radioactive material called tracer is introduced into the body and a gamma camera produces images of organs and structures

Question 12

positron emission tomography (PET)

Answer 12

computed tomography records the positrons (positively charged particles) emitted froma radiopharmaceutical to produce a cross-sectional image of the metabolic activity of body tissues to determine the presence of disease

Question 13

radiography

Answer 13

technique in which x-rays are passed through the body or area and captured on film to generate an image; also called x-ray

Question 14

single-photon emission computed tomography (SPECT)

Answer 14

radiological tech that integrates CT and radioactive material the tracer injected into the blood stream to visual blood flow to tissues and organs

Question 15

ultrasonography

Answer 15

high frequency sound waves are directed at soft tissue and reflected as “echoes” to produce an image on a monitor of an internal body structure; also called ultra sound; sonography and echo

Question 16

biopsy

Answer 16

removal of a representative tissue sample from a body site for microscopic examination usually to establish a Dx

Question 17

excisional biopsy

Answer 17

biopsy in which the entire lesion is removed

Question 18

incisional biopsy

Answer 18

biopsy in which only a small sample of the lesion is removed

Question 19

ablation

Answer 19

removal of a body part, pathway, or function by surgery, chemical destruction, electrocautery, freezing or radio frequency (RF)

Question 20

anastomosis

Answer 20

surgical joining of two ducts, vessels or bowel segments to allow flow from one to another

Question 21

curettage

Answer 21

scraping of body cavity with a spoon-shaped instrument called curette

Question 22

electrocauterization

Answer 22

use of an electrically activated instrument to burn and destroy diseased tissue (removing tumors)

Question 23

incision and drainage (I&D)

Answer 23

incision made to allow the free flow of fluids and pus from a wound, abscess or body cavity

Question 24

laser surgery

Answer 24

use of high-intensity laser light beam to remove diseased tissues, to stop bleeding or for cosmetic purposes

Question 25

revision

Answer 25

surgical procedure used to replace or compensate for a previously implanted device or correct an undesirable result or effect from a previous surgery
