What is the definition of Bilateral?
- A. Occurring on one side
- B. Present on two sides
- C. Occurring in random areas
- D. Not occurring
Correct Answer: B
Rationale: The correct definition of bilateral is something that is present on two sides. This term is commonly used in medical contexts to describe conditions or procedures that affect or involve both sides of a particular part of the body. Choice A, 'Occurring on one side,' is incorrect because bilateral refers to both sides, not just one. Choice C, 'Occurring in random areas,' is incorrect as bilateral specifically means on two sides, not random areas. Choice D, 'Not occurring,' is also incorrect as bilateral refers to something present on two sides, not the absence of occurrence.
What does Consistency refer to?
- A. Color of a fluid
- B. Degree of viscosity, how thick or thin a fluid is
- C. Taste of a fluid
- D. Smell of a fluid
Correct Answer: B
Rationale: Consistency refers to the degree of viscosity of a fluid, indicating how thick or thin it is. Viscosity is the resistance of a fluid to flow, and it determines its consistency.

Choice A, 'To lower,' is incorrect as it is the opposite of elevate. Choice C, 'To flatten,' is incorrect as it means to make something level or smooth, not to raise it. Choice D, 'To remove,' is also incorrect as it means to take something away, not to lift or raise it.
