Free Informatics Nurse Trivia Questions and Answers — Questions and Answers
Question 1: Which of the following is a good font to use when creating a user interface or website?
- Times New Roman
- Bradley hand
- Verdana (Correct answer)
- American typewriter
Correct answer: Verdana
Verdana is considered an excellent font for user interfaces and websites because it was specifically designed for optimal on-screen readability. Its wide letters, generous spacing, and clear distinctions between similar characters make it highly legible even at small sizes and low resolutions, which is crucial for digital displays. Other fonts like Times New Roman are better suited for print, while decorative fonts are less readable for extended text.
Question 2: The ergonomics requirements set forth by OSHA call for the following when a user is seated at a computer to enter or retrieve data:
- seating must be cushioned with a rounded front (Correct answer)
- user’s trunk must be perpendicular or leaning forward slightly
- front of the foot must touch the floor
- wrist must be flexed no more than 20%
Correct answer: seating must be cushioned with a rounded front
OSHA's ergonomic guidelines for computer workstations emphasize comfortable and supportive seating to prevent musculoskeletal disorders. A cushioned seat with a rounded front helps to reduce pressure on the thighs and improve circulation, promoting better posture and comfort during prolonged sitting. This design feature is crucial for maintaining user well-being and productivity in an office environment.
Question 3: A modem's function is to enable connection to:
- a printer
- the internet (Correct answer)
- plug-in device
- input devices
Correct answer: the internet
A modem (modulator-demodulator) is a device that converts digital signals from a computer into analog signals for transmission over various lines (e.g., telephone, cable, fiber optic), and vice versa. This conversion process is essential for enabling a computer to connect to and communicate with an internet service provider (ISP), thereby granting access to the internet.
Question 4: Permanent data storage in a computer is a feature of:
- hard disk (Correct answer)
- CPU
- IDE
- RAM
Correct answer: hard disk
A hard disk drive (HDD) provides permanent, non-volatile data storage in a computer. Unlike RAM (Random Access Memory), which is volatile and loses data when the power is off, a hard disk retains data even when the computer is shut down. This makes it suitable for long-term storage of operating systems, applications, and user files.
Question 5: Which of the following best summarizes Von Neumann's computer architecture model?
- CPU, monitor, keyboard, peripherals
- Program memory, data memory, CPU, intake-output
- Processor, memory, input-output (Correct answer)
- Data memory, program memory, CPU
Correct answer: Processor, memory, input-output
The Von Neumann architecture, a fundamental model for modern computers, describes a design where a single shared memory stores both program instructions and data. Its core components are the Processor (Central Processing Unit), which executes instructions; Memory, which stores both instructions and data; and Input/Output mechanisms, which handle communication with external devices. This model forms the basis of how most computers operate today.
Question 6: In general, a system with fine granularity has:
- decrease overheard
- increased overhead (Correct answer)
- decrease fields
- decrease costs of computing
Correct answer: increased overhead
In computing, 'granularity' refers to the size or scope of a task or data unit. A system with 'fine granularity' means tasks or data units are broken down into very small, detailed components. While this can offer more control or parallelism, it typically leads to increased overhead because managing and coordinating many small components requires more resources, communication, and processing time compared to fewer, larger components.
Question 7: Which of the following is acceptable as a unique identifier in addition to a name?
- Hair color
- Gender
- Age
- Birthdate (Correct answer)
Correct answer: Birthdate
A birthdate, when combined with a name, is a common and effective unique identifier in many systems, including healthcare. While not absolutely unique on its own (multiple people can share a birthdate), its combination with other demographic data like name, gender, and address significantly increases its uniqueness. This helps in accurately identifying individuals, especially in large populations, and is crucial for patient safety and data integrity.
