Which network is likely to be used by a physician accessing his/her work EHR remotely?

VPN

Which of the following represents a datum?

a singular observation

False Negative

a test result indicating that a condition is not present (negative) when in fact it is present (therefore false).

False Positive

a test result that comes out positive when it should not; often caused by comtamination or failure to run a control.

Select the reasons why physicians use screening tests instead of simply using "gold standard" (reference standard) tests:

screen tests are generally less invasive and screening tests can be used on large populations to look for potential disease

Relational database management systems link records to __________

tables

True Negative

test is negative and patient does not have disease

True Positive

test positive and have the disease
