1. What does oral mean?

A. Through the skin
B. Given through or affecting the mouth
C. Injected
D. Absorbed through digestion

Correct answer: B

Rationale: The correct answer is B: 'Given through or affecting the mouth.' Oral medications are those that are taken by mouth. Choice A is incorrect as 'Through the skin' refers to something being absorbed through the skin, not through the mouth. Choice C, 'Injected,' is incorrect as oral administration does not involve injection but rather ingestion. Choice D, 'Absorbed through digestion,' is partially correct in that oral medications are indeed absorbed through the digestive system, but the term 'oral' specifically refers to the mouth in this context.

2. What does the term 'viscous' mean?

A. Thick and sticky
B. Slimy
C. Watery
D. Dry

Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient.

4. What does the word Trepidation mean?

A. Fear
B. Misgivings
C. Confidence
D. Doubt

Correct answer: B

Choice A ('Fear') is too broad and does not capture the specific sense of unease that trepidation conveys. Choice C ('Confidence') is the opposite of what trepidation represents. Choice D ('Doubt') is related to uncertainty but does not fully encapsulate the sense of fear and anxiety associated with trepidation.

A. Block

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off.
