1. Which sentence uses 'etc.' grammatically correct?

A. The list included diseases such as flu, measles, etc.
B. The list included flu, measles, etc., and other items.
C. The list included flu, measles, etc., diseases, and other items.
D. The list included, flu, etc., measles, diseases, and other items.

Correct answer: A

Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.

2. Which word describes a screen or filter?

A. Permeable
B. Incendiary
C. Exuding
D. Resilient

Correct answer: A

Rationale: The word 'permeable' refers to a material or surface that allows liquids, gases, or substances to pass through it, while screening or filtering out impurities. This makes it an appropriate descriptor for a screen or filter, which function by allowing certain elements to pass through while retaining others. Choices B, C, and D are incorrect: 'Incendiary' means causing fires, 'Exuding' means giving off or releasing, and 'Resilient' means able to withstand or recover from difficult conditions.

3. What is the meaning of 'Exemplary'?

A. Disappointing
B. Praiseworthy
C. Ordinary
D. Unacceptable

Correct answer: B

Rationale: The correct answer is B: 'Praiseworthy.' Exemplary is used to describe something that is commendable, outstanding, or worthy of praise. Therefore, the meaning of 'Exemplary' is praiseworthy, not disappointing, ordinary, or unacceptable. Choice A is incorrect because 'Disappointing' is the opposite of 'Exemplary.' Choice C is incorrect as 'Ordinary' does not reflect the exceptional nature of 'Exemplary.' Choice D is incorrect as 'Unacceptable' is the opposite meaning of 'Exemplary.'

4. What is the meaning of NEBULOUS?

A. Clear
B. Vague
C. Precise
D. Obvious

Correct answer: B

Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.

5. If a patient has SALLOW skin, what is true?

A. Her skin has a yellow tint
B. Her skin has a blue tint
C. Her skin has a red tint
D. Her skin has a green tint

Correct answer: A

Rationale: Sallow skin is a term used to describe skin that appears yellowish in color. This discoloration can be due to various factors, such as an underlying health condition, poor circulation, or certain medications. Observing sallow skin can be an important clinical indicator that prompts further investigation into the patient's overall health status. Choice B, blue tint, is incorrect as sallow skin is not associated with a blue color. Choice C, red tint, and Choice D, green tint, are also incorrect as sallow skin specifically refers to a yellowish complexion, not red or green.
