- 4. an applied science used to promote an individual's safety and well-being by adapting to the environment and using techniques to prevent injuries.
- 6. This computerized, body-scanning method uses nuclear magnetic resonance instead of X-ray radiation. Magnetic resonance imaging alters the magnetic position of hydrogen atoms to produce an image.
- 8. Introduced in 1972, this noninvasive, computerized X-ray permits physicians to see clear, cross-sectional views of both bone and body tissues and to find abnormalities such as tumors or bleeding. It uses a pencil-thin beam of radiation to create clear, cross-sectional views of both bone and body tissues.
- 9. an organized collection of information, Information is entered into areas called fields. For example, the database may contain information such as name, address, telephone, e-mail address, insurance information, social security num
- 10. Used to protect a computer from electrical surges and power outages. It consists of a surge protector and a battery backup.
- 11. When a group of related records is combined, this is called a file.
- 14. while the patient is exercising; usually involves walking "a treadmill or riding an exercise bike until a target heart rate is reached; allows the physician to evaluate the function of the patient's heart during activity.
- 16. allow for rapid dispensing of medications. Prescriptions are sent electronically to a computerized dispensing unit.
- 21. programs that contain instructions to alter the operation of the computer programs, erase or scramble data on the computer, or allow access to information on the computer. Viruses can enter a computer through files downloaded from the Internet.
- 22. a noninvasive scanning method that uses high-frequency sound waves that bounce back as an echo when they hit different tissues and organs inside the body.
- 24. an online teaching and learning environment that uses computers and the Internet to allow teachers to present information and activities and, at times, even engage and interact with students.
- 25. allows all health care agencies to readily transfer patient electronic health records (EHRS) between agencies in a national network.
- 28. uses high-energy particles to decrease the size of tumors and treat cancer. There are two major types of this therapy: external-beam and brachytherapy.
- 29. include (A) handheld tablets and (B) laptops in compact cases.
- 34. for professional nurses, physicians, and other allied health personnel, virtual learning, patient simulator manikins, and web conferences. is educational computer programming designed for individualized use. It is user paced, user friendly, and proceeds intai an orderly, organized fashion from topic to topic. It may use video, animated graphics, color, and sound. It may be a drill-and-practice program for learning to calculate medication doses, or it may take the form of a tutorial for learning concepts about the heart. In addition, it can be a simulation that allows the learner to do a clinical procedure, such as taking a patient's blood pressure or drawing blood from a vein (venipuncture), while sitting in front of the computer.
- 36. a surgical procedure in which a surgeon uses preoperative and intraoperative images to guide or direct the surgery.
- 37. Dobutamine or adenosine stress tests are used for patients who cannot exercise; a medication that simulates the effect of exercise is given to increase the blood flow and heart rate
- 38. uses special software to perform high-speed math calculations. The user enters formulas to tell the computer to perform specific math functions (addition, subtraction, multiplication, division, percentage) with numerical data.
Down
- 1. a small amount of a radioactive substance such as thallium is given intravenously; a special camera is used to identify the rays emitted from the substance while the patient is at rest and then during exercise; allows the physician to evaluate which parts of the heart are healthy and function normally and which parts are not because a less-than-normal amount of the radioactive substance will be seen in areas of the heart with a decreased blood supply.
- 2. a computerized version of a patient's medical information that may include statistical data (name, address, telephone number, insurance information, etc.), diagnoses, medical history, treatments, medications taken, tests performed, and any other information that could be included in a patient's paper record.
- 3. allow multiple users to share the same data or information at the same time. They also allow rapid communication between individuals. Examples of communication methods that use networks include electronic mail, telemedicine, telepharmacies, and virtual communities.
- 5. a slightly radioactive substance is injected into the patient and detected by the PET scanner. This radioactive tracer travels through the body and is picked up by body cells. If there is a poor blood supply, there will be a decreased amount of tracer. This aids in the diagnosis of heart disease or other circulatory problems.
- 7. used for patients who cannot exercise; a medication that simulates the effect of exercise is given to increase the blood flow and heart rate.
- 11. protective programs that limit the ability of other computers to access a computer. A firewall alert will usually inform the user that an outside program is trying to access the computer.
- 12. place of employment, and medical history.
- 13. uses technology to direct ultrahigh-frequency sound waves through the chest wall and into the heart; a computer then converts the reflection of the waves into an image of the heart; usually a reading is taken while the patient is at rest and then another reading is taken after exercise when the heart rate rises to a target level; used to evaluate cardiac function, reveal valve irregularities, show defects in the heart walls, and visualize the presence of fluid between the layers of the pericardium (membrane that surrounds the outside of the heart).
- 15. a computerized interpretation system that produces visual pictures on a computer monitor and a printout of the electrical activity of a patient's heart; gives important information concerning the spread of electrical impulses to the heart chambers and assists in diagnosing heart disease.
- 17. is the process of sorg sending messages from one computer to another. siteq It allows health care providers to quickly send dasta of messages, memos, announcements, reports, and other data to one or more persons.
- 18. an excellent learning tool and another example of how technology has enhanced health care.
- 19. also called computer-assisted surgery, is another major technological advance. A robot is a mechanical device that is computer controlled. Most systems include a camera arm with mechanical arms that attach to surgical instruments.
- 20. a very large mainframe computer that can control the launch of a rocket to outer space.
- 23. means a basic understanding of how a computer works and the applications used in your field or profession. Computer literacy also means feeling comfortable using a computer for your job needs.
- 26. involves the use of video, audio, and computer systems t to provide medical or health care services.
- 27. originally used by engineers and designers, has also found a place in therapeutic treatment. Using three-dimensional imaging models, individuals who make prosthetics, or artificial parts, can custom design individualized prosthetics such as hands, legs, fingers, and other body parts that will precisely match the physical requirements of the individual for whom they are designed
- 30. A database is an organized collection of information, Information is entered into areas called fields.
- 31. light beams that can be focused precisely
- 32. online websites are established by a physician, health care facility, or other health care provider.
- 33. which can sit on a desktop
- 35. Each type of information is a field. Within the database, each collection of related information is called a record. All records can be edited and corrected, stored for future use, and printed or sent by e-mail or fax.
