A healthcare professional works in a military hospital from 1300 to 2000. What time of day does this healthcare professional work?

Correct Answer: C

Rationale: The shift from 1300 (1:00 PM) to 2000 (8:00 PM) corresponds to early afternoon to bedtime. Therefore, the correct answer is C, as this healthcare professional works during the early afternoon to bedtime hours. Choices A, B, and D are incorrect because the work hours fall within the early afternoon to evening time frame, not early morning, lunchtime, or midnight to sunrise.

Correct Answer: B

Rationale: To convert ounces to milliliters, we know that 1 ounce is approximately 30 mL. Therefore, 0.5 ounces would be half of that, which is 15 mL. So, 0.5 oz of perfume is equal to 15 mL. Choice A (10 mL), Choice C (20 mL), and Choice D (25 mL) are incorrect as they do not reflect the accurate conversion from ounces to milliliters.

Correct Answer: C

Rationale: The correct answer is C) 10. The metric system of measurement is based on a factor of 10 because it follows a decimal system where each unit is either 10 times larger or smaller than the unit adjacent to it. This makes conversions between different units much simpler and more intuitive compared to other measurement systems. Option A) The length of Napoleon's forearm is incorrect because the metric system was not based on any individual's body part, but rather on a universal and standardized system of measurement. Option B) 2 is incorrect because the metric system does not use a multiplication factor of 2 for its units. It is based on factors of 10 for easy conversion between units. Option D) Atomic weight of helium is incorrect because the metric system is based on the physical properties of matter but not specifically on the atomic weight of any element. In an educational context, understanding the basis of the metric system is crucial for healthcare professionals, especially in pharmacology. Dosages of medications, concentrations of solutions, and other pharmaceutical calculations are often done using the metric system. Knowing how to convert between different metric units accurately is essential for patient safety and effective medication administration.

Correct Answer: C

Rationale: To find the answer, divide 4748 by 12: 4748 · 12 = 395.666... Since we are rounding to the nearest whole number, we round up to 396 because the decimal part (.666) is greater than .5. Choice A (372) is too low as it does not account for the decimal value. Choice B (384) is also too low. Choice D (412) is too high as it goes beyond the correct rounded value.

Correct Answer: A

Rationale: To find the sum, you add the numbers 3.7, 7.289, and 4 together. 3.7 + 7.289 + 4 equals 14.989. The correct answer is 14.989 because it includes all decimal places from the sum of the numbers provided. Choice B (5.226) is incorrect as it doesn't account for the sum of the given numbers. Choice C (15.0) is incorrect as it rounds the sum to the nearest whole number, losing the decimal precision. Choice D (5.012) is incorrect as it doesn't reflect the correct sum of the decimal numbers.
