- B. Fake
- C. Accurate
- D. Honest
Correct answer: B
Rationale: The correct answer is B: 'Fake.' Counterfeit refers to something that is not genuine or a copy made to deceive. Choice A, 'Real,' is incorrect because counterfeit items are not real. Choice C, 'Accurate,' is incorrect as counterfeit implies inaccuracy. Choice D, 'Honest,' is incorrect as counterfeit items are deceptive and not honest.
2. What does 'Ingest' mean?
- A. To chew
- B. To swallow for digestion
- C. To spit out
- D. To vomit
Correct answer: B
Rationale: The correct answer is B: 'To swallow for digestion.' Ingest means to take food, drink, or another substance into the body by swallowing it. Choice A, 'To chew,' is incorrect as chewing is the act of breaking down food with the teeth. Choice C, 'To spit out,' is incorrect as it is the opposite of ingesting, involving expelling something from the mouth. Choice D, 'To vomit,' is also incorrect as vomiting is forcibly expelling the contents of the stomach through the mouth, which is the opposite of ingesting.
3. What is another word for PRECAUTION?
- A. Rule
- B. Routine procedure
- C. Preventive measure
- D. Habit
Correct answer: C
Rationale: The correct answer is 'C: Preventive measure.' A precaution is a preventive action taken to avoid harm or danger. 'Rule' (A) and 'Habit' (D) do not capture the essence of being cautious to prevent something negative. 'Routine procedure' (B) is related to a regular way of doing things, but it does not specifically imply taking action to prevent harm.
4. What does it mean if something is distended?
- A. Shrunken
- B. Swollen
- C. Narrow
- D. Flattened
Correct answer: B
Rationale: When something is described as distended, it means that it is swollen or expanded, not shrunken, narrow, or flattened. In a medical context, distention often refers to an abnormal swelling or enlargement of an organ or structure. 'Shrunken' is incorrect as it means reduced in size, 'narrow' is incorrect as it means not wide, and 'flattened' is incorrect as it means pressed or squeezed flat.
5. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'
- A. Add water to

Correct answer: A
Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.
