1. What role does the liver play in metabolism?

• A. Storing glucose
• B. Secreting bile
• C. Detoxifying harmful substances
• D. Producing enzymes

Correct answer: D

Rationale: The correct answer is D: Producing enzymes. The liver is involved in metabolism by producing enzymes that are essential for regulating various metabolic processes in the body. While the liver does store glucose, secrete bile, and detoxify harmful substances, its primary role in metabolism is producing enzymes that facilitate biochemical reactions necessary for energy production, nutrient breakdown, and waste elimination. Choices A, B, and C are incorrect because although the liver performs these functions, they are not directly related to its primary role in metabolism, which is producing enzymes.

2. Select the word or phrase in the sentence that is not used correctly: 'Her teacher asked her what would she do after she graduated from nursing school.'

• A. She
• B. From
• C. Would
• D. Her

Correct answer: C

Rationale: The correct answer is C. The phrase 'what would she do' is incorrect because in English questions, the word order for modal verbs like 'would' should be 'she would do' instead of 'would she do'. The correct structure should be 'her teacher asked her what she would do after she graduated from nursing school.' Choices A, B, and D are used correctly in the sentence and do not contain any errors.

3. According to Bernoulli's principle, when the flow velocity (v) of an incompressible fluid increases in a constricted pipe, the pressure (P) will:

• A. Depend on the specific fluid type
• B. Decrease
• C. Remain constant
• D. Increase

Correct answer: B

Rationale: Bernoulli's principle states that in a constricted pipe with increasing flow velocity of an incompressible fluid, the pressure decreases. This is due to the conservation of energy, where the total energy of the fluid (sum of kinetic energy, potential energy, and pressure energy) remains constant along the flow path. As the fluid velocity increases, its kinetic energy increases at the expense of pressure energy, causing a decrease in pressure. Therefore, the correct answer is B. Choices A, C, and D are incorrect. The pressure changes in the system are primarily driven by the fluid velocity and the conservation of energy principle, not by the specific fluid type, which is a constant. The pressure is not constant but decreases with increasing flow velocity due to the energy transformation occurring in the system. Lastly, the pressure does not increase; it decreases as the fluid velocity rises.

4. What charge do Group IIIA elements have?

• A. +1
• B. +2
• C. +3
• D. 0

Correct answer: C

Rationale: Group IIIA elements, also known as Group 13 elements, have a common oxidation state of +3. This is because they have three valence electrons and tend to lose these electrons to achieve a stable electron configuration, resulting in a +3 charge. Choice A (+1) and Choice B (+2) are incorrect because Group IIIA elements typically lose all three valence electrons to attain a stable configuration, leading to a +3 charge. Choice D (0) is incorrect as these elements do not gain electrons but rather lose them, resulting in a positive charge.

5. Select the word in the following sentence that is not used correctly. Collecting personal and vital data is one of the roles of an intake nurse.

• A. personal
• B. vital
• C. datum
• D. roles

Correct answer: C

Rationale: The word 'datum' is singular, and the correct plural form of 'datum' is 'data.' Therefore, the sentence should use 'data' instead of 'datum' to be grammatically correct. In the sentence provided, 'datum' should be replaced with 'data' to maintain proper grammar and syntax. Choices A, B, and D are used correctly in the sentence, so they are not the correct answer.
