1. When Sofia went in for her yearly check-up, her doctor suggested that they do a blood test to get an update on her hypokalemia, since its decreasing levels were worrisome in the past.

• A. Better
• B. Above
• C. Too much
• D. Not enough

Correct answer: D

Rationale: The correct answer is 'Not enough.' The prefix 'hypo-' means 'under' or 'not enough,' as seen in the word 'hypokalemia,' which refers to low levels of potassium. 'Better' (choice A), 'Above' (choice B), and 'Too much' (choice C) are all incorrect because they do not convey the meaning of insufficient or low levels associated with hypokalemia.

2. Simplify the following expression: 0.0178 × 2.401

• A. 2.0358414
• B. 0.0427378
• C. 0.2341695
• D. 0.348324

Correct answer: B

Rationale: To simplify the expression 0.0178 × 2.401, you multiply the two numbers to get the result. Therefore, 0.0178 × 2.401 = 0.0427378. Choice A (2.0358414), Choice C (0.2341695), and Choice D (0.348324) are incorrect as they do not represent the correct result of the multiplication operation.

3. Which type of muscle is responsible for moving the skeleton?

• A. Cardiac muscle
• B. Skeletal muscle
• C. Smooth muscle
• D. Voluntary muscle

Correct answer: B

Rationale: Skeletal muscle is the correct answer as it is responsible for moving the skeleton. Skeletal muscles are under voluntary control, meaning they can be consciously controlled by the individual. Cardiac muscle (Choice A) is found in the heart and is responsible for pumping blood, not moving the skeleton. Smooth muscle (Choice C) is found in internal organs and is responsible for involuntary movements like digestion. Voluntary muscle (Choice D) is not a specific type of muscle; it refers to muscles that can be consciously controlled, which includes skeletal muscles.

4. Lise is doing a research project on the various psychological theories that Sigmund Freud developed and on the modern response to those theories. To which section of the library should she go to begin looking for research material?

• A. 100
• B. 200
• C. 300
• D. 900

Correct answer: A

Rationale: The correct answer is A: '100.' Freud's theories fall under psychology, which is classified under the 100 section according to the Dewey Decimal Classification system. Section 200 is for Religion, 300 for Social sciences, and 900 for History, geography, and biography. Therefore, A is the most appropriate section for Lise to find research material related to Freud's psychological theories.

5. Which of the following types of muscle tissue is found attached to bones and allows for voluntary movement?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Connective tissue

Correct answer: C

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscle is attached to bones and allows for voluntary movement, such as walking, running, and lifting objects. Smooth muscle, found in the walls of internal organs and blood vessels, is responsible for involuntary movements. Cardiac muscle is specific to the heart and controls involuntary contraction. Connective tissue, on the other hand, provides support and connects different structures in the body, but it is not responsible for voluntary movement like skeletal muscle.
