Questions 19

Answers

1
The coronary circulation
Requires 100% of total blood ejected from left ventricle
Blood circulation throughout the body
Clinically depicted with radiography
Supplies blood to myocardium which is imaged by magnetic resonance
2
What is not true about matlab
Can manipulate arrays
Requires some kind of programming
Can be used for medical image processing
Has no graphical environment
3
The MRI scanner
Depicts magnetic dipoles of hydrogen atoms
Based on water flow
Solely based on sketch mobility
Based on signal coming from the carbons electron
4
What is true in an internet search for information in the terms “diabetes”, “hypertension”
Searching for diabetes NOT hypertension would expand results for diabetes
Searching for diabetes OR hypertension would expand results diabetes
Searching for diabetes AND hypertension expands results for diabetes
Searching for diabetes OR hypertension would limit results for diabetes
5
Difference between analog and digital signal
Analog signals take twice as much storage space on pc
Digital signal can be derived from analog signals
Sampling rate in time is half the rate of the highest frequency of signal
Analog Signals can have noise, digital signals do not
6
What is based on the mobility of the hydrogen nuclei of water
Left ventricular motility control
The imaging of myocardial edema with magnetic tomography
None
Control of the viability of the myocardium by magnetic tomography
7
For interoperability to be successful it’s enough to
Be on same telecommunications network
None
Have same interface between different hospital systems
Exchange data between different medical systems
8
Medical databases
Are used excluseviley for bio marker analysis
Register and classify only numerical data
Do not concern clinical practice
Can be accessed by different users
9
Which of the following is not a central component of an electronic patient record
Unified presentation of data
Decision support system
Patient data entry
Access to authenticated users
10
How would the logical function if two variables E=(A+B)xA’+B
E=A’
E=A+B
E=B
E=1
11
Advantages of using telemedicine applications are
Possibility of early access to biomedical data if patients and early diagno
Support of continuous training and education
Reducing cost
All
12
Reasons for using variables
Better reading of mathematical expressions
Results recalculation with variable value changer
Implementation of arithmetic operations in a table
Values that remain constant in solving the problem
13
Which of the following is true about the patient centered approach in health
Nurses register data
Patient actively participates and is responsible for maintaining health rec
Doctor sets personalized goals for patient
Doctor registers data
14
Which of the following characterizes a PHR and differentiates it from EMR and EHR
Health record initiated and maintained by an individual
Record from which the patient can see information registered by their doc
Health record created in an organization that provides care
File that contains personal information
15
Magnetic resonance in dentistry
None
Cost free
Cannot be used due to short signal duration
Gives same information of X-rays
16
Each hospitals PACS system can perform the following basic functions
All
Archiving and recalling exams in multiple ways
Basic imaging processing
Storage of all imaging tests of the hospital
17
Which of the following medical procedures can be performed in medical facilities and the pharmacy
Prescription

Payments for medical procedures
Surgery
18
Which of the following is a hierarchical structure vocabulary of terms
National library of medicine
MESH
Pubmed
Medline
19
