1. The abbreviation PDR refers to a ___________.

• A. drug
• B. procedure
• C. book
• D. muscle group

Correct answer: A

Rationale: The abbreviation PDR stands for Physician's Desk Reference, which is a widely used book containing information about prescription drugs, including their uses, side effects, and dosages. Therefore, the abbreviation PDR is associated with drugs. Choices B, C, and D are incorrect because PDR specifically relates to drugs and not procedures, books, or muscle groups.

2. The first law of thermodynamics is a principle of energy conservation. It states that:

• A. Energy can be created or destroyed.
• B. The total entropy of an isolated system always decreases.
• C. Energy can neither be created nor destroyed, only transferred or transformed.
• D. The temperature of a system is directly proportional to its entropy.

Correct answer: C

Rationale: The first law of thermodynamics states that energy cannot be created or destroyed; it can only be transferred or converted from one form to another, ensuring energy conservation in any system. Choice A is incorrect because it goes against the principle of energy conservation. Choice B is incorrect as it refers to the second law of thermodynamics, which states that the total entropy of an isolated system always increases. Choice D is incorrect because the temperature of a system is not directly proportional to its entropy.

3. Which organelle in the cell contains the genetic material?

• A. Ribosome
• B. Nucleus
• C. Mitochondria
• D. Endoplasmic reticulum

Correct answer: B

Rationale: The correct answer is B, Nucleus. The nucleus is the organelle in the cell that contains the genetic material (DNA). DNA within the nucleus determines the cell's functions and characteristics, making it essential for cell function and replication. Choice A, Ribosome, is responsible for protein synthesis, not genetic material storage. Choice C, Mitochondria, produces energy but does not contain the genetic material. Choice D, Endoplasmic reticulum, is involved in protein synthesis and lipid metabolism but does not house the genetic material.

4. The word lethargy as used in the second paragraph of the passage can best be defined as ___________.

• A. Sluggishness
• B. Irritability
• C. Energy
• D. Starvation

Correct answer: A

Rationale: In this context, 'lethargy' refers to a state of sluggishness or lack of energy. The passage mentions that people with seasonal affective disorder (SAD) struggle with lethargy and chronic fatigue, impairing their daily lives. Therefore, the correct definition of 'lethargy' in this context is 'sluggishness.' Choice B, 'Irritability,' is incorrect as lethargy refers more to a lack of energy than to being irritable. Choice C, 'Energy,' is the opposite of lethargy. Choice D, 'Starvation,' is unrelated to the definition of lethargy in this context.

5. Choose the meaning of the word 'tremulous' in the following sentence: 'The patient held out a tremulous hand and grasped the paperwork.'

• A. Wrinkled and wizened
• B. Pale and lifeless
• C. Clenched and arthritic
• D. Quivering and weak

Correct answer: D

Rationale: In this sentence, the word 'tremulous' is used to describe the patient's hand. When someone's hand is described as tremulous, it means it is quivering or shaking, indicating weakness or distress. Therefore, the correct meaning of 'tremulous' in this context is quivering and weak. Choices A, B, and C are incorrect because they do not capture the specific meaning of 'tremulous' in this context. 'Wrinkled and wizened' refers to being old and withered, 'pale and lifeless' describes a lack of color and vitality, and 'clenched and arthritic' implies a tight grip and joint inflammation, none of which accurately represent the trembling or shaking nature of a tremulous hand.
