Question 1

Which standard defines how medical images and related information are stored and transmitted between imaging devices and PACS?

Accepted Answer

DICOM

Answer

DICOM (Digital Imaging and Communications in Medicine) is the standard for handling, storing, and transmitting medical imaging data between modalities, PACS, and workstations.

Question 2

What is HL7 primarily used for in healthcare?

Accepted Answer

Exchanging clinical and administrative data between healthcare information systems

Answer

HL7 (Health Level Seven) is a set of messaging standards for exchanging patient, order, result, and administrative data between systems such as the EHR, lab, and monitoring systems.

Question 3

Why are medical devices running legacy operating systems often placed on a separate VLAN or network segment?

Accepted Answer

To limit exposure to attacks, since the devices may not be patchable

Answer

Many medical devices cannot be patched easily because of vendor validation and regulatory constraints. Network segmentation is a compensating control that limits an attacker's ability to reach them or move laterally.

Question 4

What does an IP address do on a hospital network?

Accepted Answer

Uniquely identifies a networked device so data can be routed to it

Answer

An IP address identifies a device on a network so traffic can be addressed and routed to it. Devices may use static or DHCP-assigned addresses.

Question 5

Under the HIPAA Security Rule, what type of information must be safeguarded on networked medical devices?

Accepted Answer

Electronic protected health information (ePHI)

Answer

The HIPAA Security Rule requires administrative, physical, and technical safeguards for ePHI. Devices that store or transmit patient data, such as monitors and imaging systems, fall within its scope.
