Question 1

Type: MCSA

Which statement concerning “thin client technology” is correct?

1. System processing occurs on both the server and on the local PC.
2. A thin client consists of a display with keyboard and requires its own storage device.
3. Software exists on the server, therefore upgrades are done in one step for all clients.
4. When implemented, older PCs formerly used in networking must be replaced.

Correct Answer: 3

Rationale 1: All system processing occurs on the server, rather than on the thin client or local PC, as seen in traditional client/server technology. When using thin client technology, software resides on the server requiring only one upgrade on the server rather than a physical visit to each PC or client. Security is also enhanced because users cannot locally run foreign disks/memory sticks that may contain a virus.

Rationale 2: A thin client is primarily a display, keyboard, and mouse or other pointing device and does not require local drives or storage devices. When using thin client technology, software resides on the server requiring only one upgrade on the server rather than a physical visit to each PC or client. Security is also enhanced because users cannot locally run foreign disks/memory sticks that may contain a virus.

Rationale 3: When using thin client technology, software resides on the server requiring only one upgrade on the server rather than a physical visit to each PC or client. Security is also enhanced because users cannot locally run foreign disks/memory sticks that may contain a virus.

Rationale 4: Any PC can serve as a thin client. System processing occurs on the server; therefore, older equipment may be utilized as a client with the addition of a pointing device. When using thin client technology, software resides on the server requiring only one upgrade on the server rather than a physical visit to each PC or client. Security is also enhanced because users cannot locally run foreign disks/memory sticks that may contain a virus.

Question 2

Type: MCSA

Which health risk related to computer use has been best documented?

1. Miscarriage or sterility
2. Ulnar nerve syndrome
3. Carpal tunnel syndrome
4. Cataracts

Correct Answer: 3

Rationale 1: Research has not established any clear links between computer use and miscarriage or sterility. Carpal tunnel syndrome, a repetitive-stress injury, has been researched and documented as occurring with computer use.

Rationale 2: Research has not established any clear links between computer use and ulnar nerve syndrome. Carpal tunnel syndrome, a repetitive-stress injury, has been researched and documented as occurring with computer use.

Rationale 3: Correct. Carpal tunnel syndrome, a repetitive-stress injury, has been researched and documented as occurring with computer use.

Rationale 4: Research has not established any clear links between computer use and cataracts. Carpal tunnel syndrome, a repetitive-stress injury, has been researched and documented as occurring with computer use.

Global Rationale:

Question 3

Type: MCSA

Health care information plans include adding super users to the hospital staff. Which person is most appropriate for this role?

1. An experienced staff nurse who has been employed at the institution for three years
2. An informatics nurse specialist with a master’s degree and informatics certification
3. A newly hired charge nurse who has practiced for ten years in an intensive care unit
4. A clinical nurse specialist for three departments, employed at the institution for six years

Correct Answer: 1

Rationale 1: Correct. An experienced staff nurse who has clinical experience in the institution would be very useful as a resource person.

Rationale 2: An informatics nurse specialist with a master’s degree and certification in informatics would not know the clinical area well enough or be able to answer questions from users about the hospital. An experienced staff nurse who has clinical experience in the institution would be very useful as a resource person.

Rationale 3: A newly hired charge nurse who has practiced for ten years in an intensive care unit would not know the clinical area well enough or be able to answer questions from users about the hospital computer system. An experienced staff nurse who has clinical experience in the institution would be very useful as a resource person.

Rationale 4: The clinical nurse specialist for three departments who has been employed at the institution for six years would not know the clinical area well enough or be able to answer questions from users about the hospital.

Question 4

Type: MCSA

Which example best fits the description of a local area network (LAN)?

1. One server communicates with multiple PCs and printers
2. Office computers are connected through the use of the Internet
3. Client computers are interconnected with multiple servers
4. Internet technology is used to communicate with hospital suppliers

Correct Answer: 1

Rationale 1: A local area network connects multiple PCs and printers to create a shared system.

Rationale 2: The Internet actually consists of thousands of interconnected networks. A LAN is confined to a single building or campus and has only one server.

Rationale 3: Networks with multiple servers are known as wide area networks (WANs). A LAN has only one server.

Rationale 4: The Internet actually consists of thousands of interconnected networks. A LAN is confined to a single building or campus and has only one server.
