1. How many ounces are in 0.5 liters?

• A. 16.91 oz
• B. 15.91 oz
• C. 17.91 oz
• D. 18.91 oz

Correct answer: A

Rationale: To convert liters to ounces, you need to multiply the volume in liters by 33.814. In this case, 0.5 liters multiplied by 33.814 equals approximately 16.91 ounces. This conversion is commonly used in culinary and liquid measurements. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to ounces.

2. How many feet are equal to 1 yard?

• A. 4 feet
• B. 3 feet
• C. 2 feet
• D. 5 feet

Correct answer: B

Rationale: The correct answer is B: 3 feet. This is because 1 yard is equivalent to 3 feet. The conversion factor between yards and feet is 1 yard = 3 feet. Choice A (4 feet) is incorrect as it represents the conversion of 1 yard to 4 feet, which is inaccurate. Choice C (2 feet) is incorrect as it underestimates the number of feet in 1 yard. Choice D (5 feet) is incorrect as it overestimates the number of feet in 1 yard.

3. Convert 0.025 mg to micrograms.

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you multiply by 1000, not 10000. Therefore, 0.025 mg equals 25 mcg. Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10000. Choice C (2.5 mcg) is incorrect as it incorrectly divides by 10. Choice D (0.25 mcg) is incorrect as it incorrectly multiplies by 10.

4. What is the equivalent of 0.3 mg in ml?

• A. 0.3 ml
• B. 3 ml
• C. 30 ml
• D. 0.03 ml

Correct answer: A

Rationale: The correct answer is A: 0.3 ml. To convert milligrams (mg) to milliliters (ml), you typically need the substance's density. However, in many medical contexts, especially with liquid medications similar in density to water, 0.3 mg is commonly assumed to be equivalent to 0.3 ml. Choice B (3 ml) is incorrect as it is 10 times greater than the correct conversion. Choice C (30 ml) is incorrect as it is 100 times greater than the correct conversion. Choice D (0.03 ml) is incorrect as it is one-tenth of the correct conversion.

5. What is 0.5 liters in ml?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.
