1. What type of reaction occurs when an acid and a base react to form water and salt?

• A. Neutralization reaction
• B. Decomposition reaction
• C. Combustion reaction
• D. Redox reaction

Correct answer: A

Rationale: A neutralization reaction is the correct answer. In this type of reaction, an acid and a base combine to form water and salt. The acid donates a proton (H+) to the base, forming water, while the remaining ions combine to form a salt. This reaction results in the neutralization of both the acid and the base, hence the name 'neutralization reaction.' Choice B, decomposition reaction, is incorrect because it refers to a reaction where a compound breaks down into simpler substances. Choice C, combustion reaction, is incorrect as it involves a substance reacting with oxygen to produce heat and light. Choice D, redox reaction, is incorrect because it involves the transfer of electrons between reactants.

2. What is stated in the passage?

• A. Physical illness can cause insomnia.
• B. Exercise causes insomnia.
• C. There is no solution to insomnia.
• D. Sleep is unnecessary for good health.

Correct answer: A

Rationale: The correct answer is A: 'Physical illness can cause insomnia.' The passage mentions that chronic insomnia can result from a medical illness, among other conditions. This indicates a direct link between physical illness and insomnia. Choice B is incorrect as the passage does not mention exercise causing insomnia but actually suggests developing good sleep habits as a solution. Choice C is incorrect as the passage provides solutions to insomnia, such as sleep hygiene and non-pharmacological therapies. Choice D is incorrect as the passage emphasizes the importance of getting a good night's sleep for good health, implying that sleep is necessary.

3. What is the primary role of the liver in the body?

• A. Producing insulin
• B. Detoxifying harmful substances
• C. Digesting food
• D. Storing energy

Correct answer: B

Rationale: The correct answer is B: Detoxifying harmful substances. While the liver does produce bile for digestion and stores nutrients like glycogen, its primary function is to filter and detoxify blood coming from the digestive tract before passing it to the rest of the body. Therefore, choices A, C, and D are incorrect. Producing insulin is mainly done by the pancreas, digesting food is primarily the role of the stomach and intestines, and storing energy is a function of various organs like muscles and fat cells.

4. The physician orders 60 mg of Augmentin; 80 mg/mL is on hand. How many milliliters will you give?

• A. 1 ml
• B. 0.5 ml
• C. 0.75 ml
• D. 1.25 ml

Correct answer: C

Rationale: To find the volume required, divide the prescribed dose (60 mg) by the concentration available (80 mg/mL): 60 mg ÷ 80 mg/mL = 0.75 mL. Therefore, 0.75 mL is the correct amount to administer. Choice A (1 ml) is incorrect as it does not consider the concentration of the solution. Choice B (0.5 ml) is incorrect as it is half the correct amount. Choice D (1.25 ml) is incorrect as it is more than the calculated correct amount.

5. What is the best description for the word establish in the following sentence? Physicians use patch tests to establish the specific causes of contact dermatitis.

• A. Launch
• B. Introduce
• C. Endorse
• D. Determine

Correct answer: D

Rationale: In the given sentence, the word 'establish' is used in the context of identifying or finding out the specific causes of contact dermatitis through patch tests. The most fitting description for 'establish' in this context is 'Determine,' as it signifies the action of figuring out or ascertaining the specific causes. 'Launch,' 'introduce,' and 'endorse' do not capture the essence of what the physicians are doing in this scenario. They are not launching, introducing, or endorsing the causes; instead, they are trying to determine them through the patch tests.
