HHE 300 EXAM 2 STUDY GUIDE UPDATED
QUESTIONS AND CORRECT ANSWERS
Question:
1. what is a diagnostic procedure?
Answer:
techniques/methods used to determine diagnosis
- can be invasive/ non-invasive
Question:
2. what is a diagnostic test?
Answer:
analysis of the specimen removed from the patient
- examples: urine sample, bloodwork, biopsy
Question:
3. why do we use diagnostic test?
Answer:
- to establish a diagnosis
- provide prognosis information
- screen for a disease in an asymptomatic patient
- monitor treatment
- provide a patient is free from a disease
Question:
4. what is a cytologic test/exam and an example?
Answer:
lab examination of cells to see what the cells look like and how they form/function
- usually performed to work for cancers and infections examples: pap smear, fine needle aspiration
Question:
5. what is a histologic test/exam and an example?
Answer:
removal or a small sample of tissue cells (invasive)
- performed in different types of biopsies examples: tissue biopsy or surgical specimen
Question:
6. what is an electroencephalogram (EEG)?
Answer:
painless procedure that measures and detects abnormal patterns in the brain waves- patches placed on the
scalp purpose: to detect brain tumors and strokes, assess and detect sleep disorders, assess brain injuries,
diagnose and monitor seizures
Question:
7. what is an electrocardiogram (ECG)?
, Answer:
procedures that measure and record the electrical activity of the heart- metal discs with thin wires patches
attached to the PT's skin purpose: detect abnormal heart rhythms, identify heart muscle damage, assess the
size and position of the heart chambers, monitor the effectiveness of heart medications
Question:
8. what is a nerve conduction study (NCS)?
Answer:
somewhat painless procedure that measures how fast and effectively electrical signals travel along nerves
purpose: identify nerve damage and neuromuscular disorders, diagnose carpal tunnel syndrome, peripheral
neuropathy, herniated discs, and ALS
Question:
9. what is a echocardiogram (ECHO)?
Answer:
painless ultrasound that creates detailed images of heart purpose: assess the structure and functioning of
heart, detect heart defects such as congenital heart disease, look for signs of heart failure
Question:
10. which tests use radiation?
Answer:
CT scans: painless scan- advanced x-ray that uses a computer to make pictures inside of the body, CT/CAT
scans cross-sectional pictures of the body purpose: show internal organs that are impossible to show in
x-rays, dye can be used to improve the visibility of certain tissues or blood vessels, measure how deep
within the body , detect blood vlots and internal bleeding
x-rays: painless- uses electromagnetic radiation to make images, images used to record on film purpose:
detect broken bones, cavities in teeth, reveal arthritis and other joint problems, detect and locate foreign
objects in the body, diagnose pneumonia and other lung infections
pet scan: uses a radioactive substance to show how tissues, organs, and structures are changing- can detect
cancer purpose: detect and stage cancer, monitor the effectiveness of treatment, evaluate brain and heart
function, and provide a more complete picture of the patient's condition
cardiac stress test: pictures taken at rest and another after exercise, one lying down, then an image taken at
peak heart rate and lying down again purpose: how blood goes to the heart at rest and during exercise
Question:
11. what is inflammation?
Answer:
body's immunologic response to tissue damage caused by the invasion of foreign bodies, microorganisms,
or harmful chemicals (trauma from physical agents, chemical agents, allergens, and pathogenic organisms)
- may be acute or chronic- at site of injury there is a large number of white bloods cells examples: burns,
insect bites, cuts, etc
Question:
12. what is an infection?
