1. A key parameter in fluid selection is specific gravity (SG). For a submerged object in a reference fluid (often water), SG = ρ_object / ρ_reference. An object with SG > 1 will:

• A. Experience a net buoyant force acting upwards
• B. Experience a net buoyant force acting downwards
• C. Remain neutrally buoyant
• D. Require knowledge of the object's volume for buoyancy determination

Correct answer: A

Rationale: When the specific gravity (SG) of an object is greater than 1, it indicates that the object is denser than the reference fluid, which is often water. According to Archimedes' principle, an object with SG > 1 will experience a net buoyant force acting upwards when submerged in the fluid. This is because the buoyant force is greater than the weight of the object, causing it to float. Therefore, the correct answer is A: 'Experience a net buoyant force acting upwards.' Objects with SG < 1 would sink as they are less dense than the fluid, while objects with SG = 1 would be neutrally buoyant, neither sinking nor floating.

2. As the leader of a group, the charge nurse is open to new ideas and thoughts of the group. The charge nurse encourages the group to participate in making decisions. This type of leadership is called:

• A. Laissez-faire
• B. Autocratic
• C. Democratic
• D. Direct

Correct answer: C

Rationale: The correct answer is 'Democratic.' A 'Democratic' leadership style involves the leader being open to new ideas and thoughts from the group and encourages group participation in decision-making. This style promotes collaboration, communication, and inclusivity in decision-making processes. 'Laissez-faire' leadership is characterized by a hands-off approach with minimal guidance or direction. 'Autocratic' leadership is where the leader makes decisions without much input from the group. 'Direct' leadership is not a widely recognized leadership style in this context.

3. Identify the grammatically correct sentence.

• A. Which one do you want?
• B. Pick the one you want.
• C. Whose one do you want?
• D. Who do you want?

Correct answer: A

Rationale: The correct sentence is 'Which one do you want?' Choice A is grammatically correct as it forms a question using 'which' to inquire about a specific choice. Choices B, C, and D contain errors in phrasing or grammar. Choice B includes a misspelling of 'want,' choice C uses 'whose' incorrectly, and choice D incorrectly combines 'who' and 'is' without proper context.

4. Select the word or phrase that makes the following sentence grammatically correct. If Angela attends the seminar tomorrow, she ___________ the employee discount.

• A. gave
• B. gives
• C. will given
• D. will be given

Correct answer: D

Rationale: The correct answer is 'D: will be given.' In the sentence, the future passive voice is needed to convey that Angela will receive the employee discount if she attends the seminar. 'Will be given' is the appropriate phrase to express this passive construction. Choices A, B, and C are incorrect as they do not form the correct future passive structure required in the sentence.

5. A man is reading a book with 798 pages. If he reads 2 chapters a day and each chapter has 6 pages, how many days will it take him to finish the book?

• A. 133 days
• B. 399 days
• C. 66.5 days
• D. 75 days

Correct answer: C

Rationale: To find the total number of chapters, divide the total number of pages by the number of pages per chapter: 798 ÷ 6 = 133 chapters. Reading 2 chapters per day means it will take 133 ÷ 2 = 66.5 days. Choice A, 133 days, is incorrect because it miscalculates the days needed to finish the book. Choice B, 399 days, is incorrect as it doesn't consider the number of chapters read per day. Choice D, 75 days, is incorrect as it doesn't account for the total number of chapters in the book.
