1. What is the correct name of ZnSO₄?

• A. Zinc sulfate
• B. Zinc sulfide
• C. Zinc sulfur
• D. Zinc oxide

Correct answer: A

Rationale: The correct name of ZnSO₄ is zinc sulfate. In this compound, zinc is combined with the polyatomic ion sulfate (SO₄). Sulfate is a common anion formed from sulfur and oxygen atoms. Therefore, the correct name for ZnSO₄ is zinc sulfate. Choice B, Zinc sulfide, is incorrect because sulfide is a different anion (S²⁻) compared to sulfate (SO₄²⁻). Choice C, Zinc sulfur, is incorrect as it does not represent the correct anion in the compound. Choice D, Zinc oxide, is incorrect as it involves an oxygen anion, not sulfate.

2. A scientist needs 12 mL of a solution. They have a bottle with 12L in it. Do they have enough?

• A. Yes, they have exactly what they need
• B. Yes, they have more than what they need
• C. No, they do not have enough
• D. None of the above

Correct answer: B

Rationale: 1 liter has 1000 milliliters. To convert from milliliters to liters, the decimal point moves three places to the left. So, the bottle has 12000 mL of solution, which is a lot more than the required 12 mL. Therefore, the scientist has more than what they need. Choice A is incorrect as the bottle has more than the required amount. Choice C is incorrect as the bottle contains significantly more solution than needed. Choice D is incorrect as the scientist does have more than enough solution.

3. What is another word for ANTICIPATE?

• A. Predict
• B. Evaluate
• C. Compare
• D. Forestall

Correct answer: A

Rationale: The correct answer is 'A: Predict.' Anticipate and predict are synonyms, both implying foreknowledge or expectation. 'B: Evaluate,' 'C: Compare,' and 'D: Forestall' do not directly relate to the meaning of anticipate and are therefore incorrect choices.

4. Which material has the smallest specific heat capacity?

• A. water
• B. wood
• C. aluminum
• D. glass

Correct answer: C

Rationale: Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Among the options provided, aluminum has the smallest specific heat capacity. This means that it requires the least amount of heat to raise its temperature compared to water, wood, and glass. Water has a high specific heat capacity, making it resistant to temperature changes, while wood and glass have higher specific heat capacities compared to aluminum.

5. The abbreviation DTs on a patient’s chart stands for ___________.

• A. deep tendon reflex
• B. descending thorax
• C. delirium tremens
• D. dextrose in water

Correct answer: C

Rationale: The abbreviation DTs on a patient's chart stands for delirium tremens, which is a severe form of alcohol withdrawal. Symptoms of delirium tremens include confusion, hallucinations, severe agitation, seizures, and autonomic instability. This condition requires prompt medical treatment to prevent serious complications. Choices A, B, and D are incorrect. Deep tendon reflex (A) refers to the reflex response elicited by tapping a tendon with a reflex hammer, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for various medical purposes but is not represented by the abbreviation DTs.
