Metric Conversions for Nursing

1. Convert 1.25 kilograms to grams.

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 1.25 kilograms is equal to 1.25 x 1000 = 1,250 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.

2. What is the difference between alpha decay and beta decay?

Correct answer: B

Rationale: The correct answer is B. Alpha decay involves the release of a helium nucleus, which consists of two protons and two neutrons. In contrast, beta decay releases an electron (beta-minus decay) or a positron (beta-plus decay). This significant distinction in the particles emitted during the decay processes distinguishes alpha decay from beta decay. Choice A is incorrect because alpha and beta decay release different types of particles. Choice C is incorrect as beta decay is more common than alpha decay in many cases. Choice D is incorrect as it does not specifically address the particles released during alpha and beta decay.

3. How many grams are in one kilogram?

Correct answer: B

Rationale: The correct answer is B: 1000 grams. This is because by definition, 1 kilogram is equal to 1000 grams. Choice A, 100 grams, is incorrect as it underestimates the actual conversion. Choice C, 500 grams, and Choice D, 2000 grams, are also incorrect as they do not align with the correct conversion factor of 1 kilogram to 1000 grams.

4. Joann has brainstormed, created an outline, and completed research for a major term paper. Which of the following is the next step she should complete in the writing process?

Correct answer: D

Rationale: After completing research and outlining, the next logical step in the writing process is drafting. Drafting involves putting together the first version of the paper based on the outline and research. This step focuses on organizing thoughts, expanding ideas, and structuring the content. Editing (choice A) occurs after drafting and involves revising and refining the content for clarity, coherence, and correctness. Publishing (choice B) is the final step where the finished work is made available to the audience. Proofreading (choice C) typically follows editing and focuses on correcting spelling, grammar, and punctuation errors.

5. Two identical balls, one made of clay and the other made of steel, are dropped from the same height. Which ball reaches the ground first, neglecting air resistance?

Correct answer: C

Rationale: In the absence of air resistance, both balls will experience the same acceleration due to gravity (9.8 m/s^2) regardless of their densities or materials. This means that both balls will reach the ground at the same time, assuming they are dropped from the same height simultaneously. The differences in density or material composition do not affect the rate at which objects fall in a vacuum. Therefore, both the clay and steel balls, being identical in shape and starting position, will have the same free-fall acceleration and will hit the ground simultaneously. Choices A and B are incorrect because the density of the materials does not impact the time it takes for objects to fall under gravity alone. Choice D is incorrect as the initial velocities do not play a role in the time taken to fall in a vacuum, where only the acceleration due to gravity affects the motion.
