1. What is Diffusion?

• A. Movement of materials from low concentration to high concentration
• B. Movement of materials from high concentration to low concentration
• C. Absorption of nutrients
• D. Breaking of materials

Correct answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.

2. 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.

3. Select the meaning of the underlined word in the following sentence. At this point, we are providing mainly palliative care.

• A. Scientific
• B. Surgical
• C. Soothing
• D. Serious

Correct answer: C

Rationale: In the context of the sentence, 'palliative care' refers to care that is focused on providing relief from the symptoms and stress of a serious illness. It is not aimed at curing the illness but rather at providing comfort and improving quality of life. Therefore, the meaning of 'palliative' in this context is to soothe or alleviate suffering, making 'soothing' the correct choice. The other options, 'scientific,' 'surgical,' and 'serious,' do not capture the essence of palliative care, which is centered around providing comfort and relief rather than focusing on scientific or surgical interventions or emphasizing seriousness.

4. What does 'Discrete' mean?

• A. Continuous
• B. Distinct or separate
• C. Mixed
• D. Combined

Correct answer: B

Rationale: The correct answer is B, 'Distinct or separate.' Discrete refers to something that is individually separate and distinct, not continuous (choice A), mixed (choice C), or combined (choice D). In mathematics and other fields, discrete items are countable and distinct from each other.

5. The electrolytes in human bodies include sodium, potassium, calcium, and ___________, among others.

• A. magnesium
• B. manganese
• C. magnetite
• D. manganite

Correct answer: A

Rationale: Magnesium is another essential electrolyte in the human body, along with sodium, potassium, and calcium. Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, regulating blood pressure, and supporting the immune system. Manganese (Choice B), magnetite (Choice C), and manganite (Choice D) are not electrolytes found in the human body. Manganese is a mineral but not an electrolyte, while magnetite and manganite are compounds and not essential electrolytes for bodily functions.
