1. What is the difference between a ventral and dorsal root of a spinal nerve?

A. Ventral carries motor, dorsal carries sensory information.
B. Ventral carries sensory, dorsal carries motor information.
C. Ventral is larger, dorsal is smaller.
D. Ventral is located anteriorly, dorsal is posteriorly.

Correct answer: A

Rationale: The correct answer is A: 'Ventral carries motor, dorsal carries sensory information.' Ventral roots of spinal nerves contain motor fibers that carry signals from the central nervous system to muscles and glands, controlling movement and function. Dorsal roots, on the other hand, contain sensory fibers that transmit information such as touch, pain, and temperature from the peripheral nervous system to the central nervous system for processing. Understanding this distinction is crucial for comprehending how information is transmitted and processed in the nervous system.

2. Approximately how many muscles are there in the human body?

A. 100
B. 100
C. 600
D. Over 600

Correct answer: D

Rationale: The correct answer is D. There are over 600 muscles in the human body. Muscles are responsible for movement, posture, and generating heat in the body. The exact number of muscles can vary slightly from person to person, but it is generally accepted that there are over 600 muscles in the human body. These muscles work together to allow us to perform various movements and activities throughout our daily lives.

3. What is the general formula for an alkyl halide?

A. CnH2n
B. CnH2n+2
C. CnH2n-1X
D. CnH2nO

Correct answer: C

Rationale: The general formula for an alkyl halide is $C_nH_{2n-1}X$, where X represents a halogen (e.g., F, Cl, Br, I).

4. The process of a gas changing into a liquid is called:

A. Evaporation
B. Boiling
C. Condensation
D. Sublimation

Correct answer: C

Rationale: Condensation happens when gas particles lose energy and slow down, transitioning into the liquid state.

5. The defining characteristic of an element is determined by the number of:

A. Neutrons in its nucleus
B. Electrons surrounding the nucleus
C. Protons in its nucleus
D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Protons in its nucleus.' An element is defined by the number of protons in its nucleus, known as the atomic number. This number determines the element's identity and its placement on the periodic table. Neutrons and electrons play important roles in an atom, but they do not define the element itself. Neutrons contribute to the atom's mass, while electrons are involved in chemical reactions and bonding. Therefore, the number of protons is the defining characteristic of an element.

6. St. Raphael Medical Center just opened its new Performance Improvement Department. Ms.

A. Make an interpretation about strengths and weaknesses
B. Identify the values of the department
C. Identify structure, process, outcome standards & criteria
D. Measure actual performances

Correct answer: B

Rationale: The correct answer is B: 'Identify the values of the department.' When a new department is established, it is important to define its core values, beliefs, and principles to guide its operations. This helps create a shared understanding among staff and stakeholders about the department's purpose and priorities. By identifying the values of the Performance Improvement Department at St. Raphael Medical Center, employees can align their actions with the department's mission and goals, fostering a cohesive and effective work environment. Options A, C, and D are not directly related to establishing the foundational values of a new department, making them less relevant in this context.
