Nursing Metric Conversions

1. How many ounces are in one gallon?

Correct answer: B

Rationale: The correct answer is B: 128 ounces. One gallon is equivalent to 128 ounces. This conversion relationship is commonly used in cooking, baking, and various liquid measurements. Choice A (64 ounces) is incorrect as it represents half the amount of a gallon. Choice C (100 ounces) and Choice D (150 ounces) are also incorrect, as they do not accurately reflect the conversion of a gallon to ounces.

2. Convert 0.1 liter to milliliters. What is the equivalent volume?

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply the number of liters by 1,000 because there are 1,000 milliliters in a liter. Therefore, 0.1 liter is equal to 100 milliliters. Choice A (1 ml) is incorrect because it represents the conversion of 0.01 liters, not 0.1 liters. Choice B (10 ml) is incorrect as it also represents the conversion of 0.01 liters. Choice D (1000 ml) is incorrect as it represents the conversion of 1 liter, not 0.1 liter.

3. Robert secures three new clients every eight months. After how many months has he secured 24 new clients?

Correct answer: C

Rationale: To determine the number of months it takes for Robert to secure 24 new clients, we set up a proportion: 3 clients / 8 months = 24 clients / x months. Cross multiplying gives 3x = 8 * 24. Solving for x results in x = 64 / 3 = 52. Therefore, after 52 months, Robert has secured 24 new clients. Choice A (64) is incorrect as it miscalculates the solution. Choices B (58) and D (66) are also incorrect as they do not reflect the accurate calculation based on the given information.

4. Select the book title that does not contain a preposition.

Correct answer: D

Rationale: The correct answer is 'D' - 'And Then There Were None.' This title does not contain a preposition. Prepositions are words that show the relationship of a noun or pronoun to another word in the sentence. In this title, 'And,' 'Then,' 'There,' and 'None' are not prepositions; they are conjunctions and pronouns. Choices A, B, and C all contain prepositions: 'in,' 'of,' and 'on,' respectively. Therefore, they are incorrect answers for this question.

5. Iron is a transition metal, which means it often forms a cation with a charge of what?

Correct answer: C

Rationale: The correct answer is C: 2+ or 3+. Transition metals, like iron, are known for their ability to exhibit variable oxidation states. This characteristic allows them to form cations with charges such as 2+ or 3+. Specifically, iron can form cations with these charges due to the varying electron configurations in its d-orbitals. The other choices are incorrect because transition metals typically form positively charged cations, not negatively charged ones. Additionally, while iron can form cations with charges of 2+ or 3+, it does not commonly form cations with charges of 1- or 1+. Transition metal cations play a crucial role in forming coordination complexes with ligands, highlighting their importance in various chemical reactions.
