Nursing Metric Conversion

1. What is 1500 milliliters in liters?

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.

2. Which of the following is best identified as a hypothesis?

Correct answer: A

Rationale: Choice A is the best example of a hypothesis as it presents a testable statement regarding the impact of environmental temperature on plant root growth. A hypothesis should be specific and capable of being tested through experimentation, which is demonstrated in choice A. Choice B is a general statement rather than a testable hypothesis. Choice C lacks specificity and does not clearly state a cause-and-effect relationship to be tested. Choice D provides a specific time frame but does not address a relationship that can be tested through experimentation, making it less suitable as a hypothesis compared to choice A.

3. Convert 345 kilometers to meters (m).

Correct answer: B

Rationale: To convert kilometers to meters, you need to multiply by 1,000 since there are 1,000 meters in a kilometer. Therefore, 345 km multiplied by 1,000 equals 345,000 meters. Choice A is incorrect as it incorrectly places the comma. Choice C is incorrect as it adds an extra zero at the end. Choice D is incorrect as it adds an extra zero at the beginning, resulting in an incorrect conversion.

4. What is the atomic number of an atom?

Correct answer: A

Rationale: The correct answer is A: The atomic number of an atom is the number of protons in its nucleus. This number uniquely identifies the element, as each element has a distinct number of protons. Neutrons and electrons play roles in the atom's structure and stability, but the atomic number specifically refers to the number of protons. Choice B (The number of neutrons in an atom) is incorrect because the atomic number does not include neutrons; it only represents the number of protons. Choice C (The number of electrons in an atom) is incorrect because the atomic number is not related to the number of electrons, which can vary in different atomic configurations. Choice D (The sum of protons and neutrons) is incorrect because it refers to the mass number of an atom, which is the total number of protons and neutrons in the nucleus, not just the protons.

5. Which word in the passage shows that the plunger is depressed and air is pushed out at the same time?

Correct answer: C

Rationale: The correct answer is 'C: As.' In the provided extract, the word 'As' is used to indicate the simultaneous action of depressing the plunger and pushing out the air. It establishes a connection between the two actions, showing that they occur together. Choice A, 'Out,' refers to the result of pushing the air out, not the action happening simultaneously. Choice B, 'Continued,' suggests a subsequent action rather than a simultaneous one. Choice D, 'Causes,' indicates a cause-and-effect relationship, not the action happening simultaneously like the word 'As' does.
