1. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. A patient's oxygen flow rate is set at 4 liters per minute. How many cubic centimeters of oxygen are delivered per minute?

• A. 400 cubic centimeters
• B. 4,000 cubic centimeters
• C. 40,000 cubic centimeters
• D. 400,000 cubic centimeters

Correct answer: B

Rationale: Remember 1 liter is equal to 1000 cubic centimeters. Multiply the flow rate in liters per minute by the conversion factor: 4 liters/minute * 1000 cm³/liter = 4,000 cubic centimeters/minute.

3. Which technique best helps maintain consistency in writing style?

• A. Writing freely without a clear outline or structure.
• B. Using different vocabulary and sentence structures in each paragraph.
• C. Establishing a style guide with agreed-upon terminology and formatting.
• D. Relying on thesaurus suggestions for varied word choices.

Correct answer: C

Rationale: A style guide ensures consistency in tone, terminology, and formatting across different pieces of writing.

4. Scientific findings are constantly evolving. This emphasizes the importance of:

• A. Unquestioning belief in established theories and models.
• B. Dogmatically adhering to the opinions of prominent scientists.
• C. Maintaining an open mind and willingness to consider new evidence.
• D. Prioritizing quick and decisive answers over careful evaluation.

Correct answer: C

Rationale: Science is a dynamic process built on continual questioning and refining of understanding. Openness to new evidence and revision of existing theories is crucial for scientific progress.

5. Which hormone is crucial for stimulating sperm production in males?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Insulin

Correct answer: C

Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone and is crucial for stimulating sperm production in males through the process of spermatogenesis. It is produced in the testes and plays a key role in the development and maintenance of male reproductive tissues, including the testes and prostate. Estrogen and progesterone are primarily female sex hormones, while insulin regulates blood sugar levels and metabolism. Therefore, testosterone is the hormone specifically responsible for stimulating sperm production in males.

6. Discern the INCORRECT function of the liver.

• A. Bile production, aiding digestion.
• B. Blood protein synthesis, such as albumin.
• C. Glucose storage for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.
