1. 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.

2. Which of the following is a weak acid commonly found in citrus fruits?

• A. Sulfuric acid (Hâ‚‚SOâ‚„)
• B. Hydrochloric acid (HCl)
• C. Citric acid
• D. Nitric acid (HNO₃)

Correct answer: c

Rationale: Citric acid is a weak acid commonly found in citrus fruits. The other choices are strong acids.

3. What happens to the kinetic energy of an object when its velocity is doubled?

• A. Kinetic energy remains the same
• B. Kinetic energy is halved
• C. Kinetic energy doubles
• D. Kinetic energy quadruples

Correct answer: c

Rationale: Kinetic energy is directly proportional to the square of an object's velocity.

4. The ureters are paired tubes that transport urine from the:

• A. Bladder to the urethra
• B. Kidneys to the bladder
• C. Urethra to the kidneys
• D. Skin to the kidneys

Correct answer: B

Rationale: The correct answer is B: 'Kidneys to the bladder.' The ureters are paired tubes that carry urine from the kidneys to the bladder. Once urine is produced in the kidneys, it travels through the ureters to be stored in the bladder until it is eliminated from the body through the urethra. Option A, 'Bladder to the urethra,' is incorrect because the ureters transport urine from the kidneys to the bladder, not from the bladder to the urethra. Option C, 'Urethra to the kidneys,' and option D, 'Skin to the kidneys,' are both inaccurate as they do not describe the correct direction of urine flow in the urinary system. Understanding the anatomy and function of the urinary system is essential for comprehending how urine is produced and excreted by the body.

5. The process of a gas changing directly into a solid is called:

• A. Condensation
• B. Deposition
• C. Sublimation
• D. Evaporation

Correct answer: B

Rationale: This process, also known as sublimation, involves gas particles losing energy and transitioning directly into the solid state.

6. What is the recommended daily fiber intake for adults?

• A. 10 grams
• B. 25 grams
• C. 35 grams
• D. 50 grams

Correct answer: B

Rationale: Rationale: The recommended daily fiber intake for adults is around 25 grams for women and 38 grams for men. Fiber is essential for maintaining a healthy digestive system, preventing constipation, and reducing the risk of chronic diseases such as heart disease and diabetes. Consuming an adequate amount of fiber can also help with weight management and promote overall well-being. Therefore, option B is the most appropriate answer based on the recommended daily intake guidelines for adults.
