1. Which of the following words or phrases fits best in the following sentence? The radiology department sends Troy to pick up lunch ______ it isn’t too busy at the office.

• A. as long as
• B. as if
• C. after
• D. unless

Correct answer: A

Rationale: The phrase 'as long as' is used to indicate a condition that needs to be met for the main clause to happen. In this sentence, the radiology department sends Troy to pick up lunch only if it isn't too busy at the office, so 'as long as' is the most suitable phrase to convey this conditional relationship. Choice B, 'as if,' implies a hypothetical comparison rather than a condition. Choice C, 'after,' suggests a sequence of events rather than a condition. Choice D, 'unless,' introduces a negative condition which does not fit the context of the sentence.

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. When light travels from air into a denser medium like glass, its speed:

• A. Increases
• B. Decreases
• C. Remains constant
• D. Becomes unpredictable

Correct answer: B

Rationale: When light travels from air into a denser medium like glass, its speed decreases. This is because the higher refractive index of the denser medium causes light to slow down as it propagates through the medium. Choice A is incorrect because the speed of light decreases in a denser medium. Choice C is incorrect because the speed of light changes when it enters a denser medium. Choice D is incorrect because the change in speed is predictable based on the refractive index of the medium.

4. Which form of fermentation is used to produce beer?

• A. Lactic acid fermentation
• B. Acetic acid fermentation
• C. Propionic acid fermentation
• D. Ethyl alcohol fermentation

Correct answer: D

Rationale: The correct answer is D, Ethyl alcohol fermentation. During beer production, yeast metabolizes sugars in the wort to produce ethanol (ethyl alcohol) and carbon dioxide, which are responsible for the alcohol content and carbonation in beer. Choices A, B, and C are incorrect because lactic acid fermentation produces lactic acid, acetic acid fermentation produces acetic acid, and propionic acid fermentation produces propionic acid, none of which are used in the production of beer.

5. What is the result of multiplying 10 by 5?

• A. 65
• B. 50
• C. 45
• D. 55

Correct answer: B

Rationale: The correct answer is B. To find the result of multiplying 10 by 5, you perform the calculation: 10 × 5 = 50. Choices A, C, and D are incorrect because they do not represent the accurate product of 10 multiplied by 5.
