the identification of a patient's disease, disorder, or injury. Diagnoses are made by examining a patient, analyzing the patient's health condition, and performing tests to collect more information.
diagnostic healthcare professional
a healthcare worker who is specially trained to make patient diagnoses.
Signs
health conditions that can be identified or observed by healthcare professionals.
Symptoms
feelings and sensations that a person experiences
vital signs
the basic measures of the patient's physical health and include blood pressure, temperature, pulse rate, and respirations
A __________ is the identification of a patient's disease, disorder, or injury.
diagnosis
What is a symptom?
feeling or sensation that is experienced by the patient
Blood test
the sampling and analyzing of a patient's blood, usually drawn from the arm, which is performed to see whether the patient is healthy or has a condition
Urine test
the sampling and analyzing of a patient's urine, which is performed to check whether the patient has any hidden diseases or conditions; also called urinalysis
Biopsy
an invasive procedure that involves removing a sample of a patient's internal tissues for the purpose of diagnosing a condition
Allergy test
a test performed on the blood or skin for a reaction to determine whether a patient has an allergy
Allergies
physical responses to allergens, which are substances that cause the body to have an adverse reaction
Specialists
healthcare professionals who are experts in a particular field of medicine.
What kind of medical test would a diagnostic healthcare professional order to collect a sample of a patient's internal tissues for analysis?
biopsy
Magnetic Resonance Imaging (MRI)
technology, which uses magnets to create images of parts of the body that are injured or have problems
laboratory analyzers
machines that analyze blood and urine samples, make it possible for lab samples to be analyzed with more precision and efficiency for faster, more reliable results.
What are some possible facilities in which a diagnostics healthcare professional might work? Check all of the boxes that apply.
-hospitals
-medical laboratories
-government agencies
-doctor's offices
-clinics
-research companies
electrocardiograph (ECG) technician
a professional who operates an electrocardiograph machine.
electrocardiograph (ECG) machine
a machine that produces visible waves on a computer monitor that represent electrical activity within the heart.
electrodes
electrical conductors
MRI technologist
a professional who operates an MRI machine
MRI machines
use high-powered magnets to take images of internal bodily structures; are highly effective at looking at soft tissues, such as knee ligaments, the brain, or the heart.
Which of the following are true about ECG machines? Check all of the boxes that apply.
-They use electrodes.
-They are used to assist doctors in the diagnosis of possible heart problems
Which of the following are true about MRI machines? Check all of the boxes that apply.
-They use magnets to produce images of soft tissues.
-The patient must not be wearing any metal during the test.
cardiovascular technologist
a professional who performs diagnostic tests and assists with procedures related to the heart; may monitor and assist doctors during heart surgery, and may perform tests to check for normal heart function.
echocardiogram
a procedure that converts sound waves of the heart into images.
radiologic technician
a person who operates an X-ray machine
X-ray machine
a machine that uses X-rays and photographic film to produce an image of internal bodily structures, such as bone.
X-rays
a form of energy
X-rays
X-ray images are often used by physicians to diagnose diseases, disorders, and injuries of the bone. For example, an X-ray can be used to determine whether a bone is broken.
X-rays
X-rays are useful for medical imaging, but they damage tissues, so it is important to limit the amount of exposure a person has to them.
medical laboratory technologist
a healthcare professional who assists pathologists in a lab
pathologist
a doctor who studies the presence and cause of disease in body tissues, fluids, and cells.
A _____________ is a person who operates an X-ray machine.
radiologic technichian
A ___________ is a healthcare professional who assists pathologists.
medical laboratory assistant
A __________ assists with procedures related to the heart and performs diagnostic tests such as echocardiograms.
cardiovascular technologist
