Nursing Elites

1. The final sentence suggests that the debate surrounding UBI necessitates

• A. Focusing on the potential cost savings for governments compared to existing welfare programs.
• B. Prioritizing the opinions of economists and financial experts over those of social scientists and philosophers.
• C. Engaging in thoughtful and informed discussions considering both the economic and ethical implications.
• D. Dismissing the concerns of critics and implementing UBI as a rapid solution to poverty and inequality.

Correct answer: C

Rationale: The emphasis on "complex interplay" and "careful consideration" suggests a call for nuanced and multifaceted discussions, aligning with C.

2. A medication order is for 250 micrograms of a drug to be administered subcutaneously. The available syringe measures in milliliters. How many milliliters should the nurse draw up?

• A. 0.00025 milliliters
• B. 0.0025 milliliters
• C. 0.025 milliliters
• D. 0.25 milliliters

Correct answer: B

Rationale: First convert micrograms to milliliters, knowing 1000 micrograms equal 1 milliliter. Divide the desired dosage (250 micrograms) by the conversion factor (1000 micrograms/milliliter) to find the volume needed: 250 micrograms / 1000 micrograms/milliliter = 0.00025 milliliters. However, drawing such a small volume might be inaccurate, so round to the nearest practical measurement, which is 0.0025 milliliters.

3. Two experiments investigating the same phenomenon produce conflicting results. What is the most appropriate next step?

• A. Ignore the conflicting results and focus on the more convincing experiment.
• B. Conduct a combined experiment incorporating elements of both.
• C. Attack the methodology of the experiment with conflicting results.
• D. Accept the more recent experiment as definitively correct.

Correct answer: C

Rationale: When faced with conflicting results from two experiments, it is important to critically evaluate the methodology of both experiments. By examining the experimental design, variables controlled for, sample sizes, and potential sources of bias, one can better understand the reasons behind the discrepancies. Attacking the methodology of the experiment with conflicting results can help identify potential flaws or limitations that may explain the differences in outcomes. This approach allows for a more informed decision on how to proceed, rather than simply ignoring or accepting one set of results over the other.

4. In the reaction 2Na + 2H2O → 2NaOH + H2, what is the limiting reactant when 3 moles of sodium react with 2 moles of water?

• A. Na
• B. H2O
• C. NaOH
• D. H2

Correct answer: a

Rationale: Sodium is the limiting reactant because it runs out first in a 1:1 ratio with water.

5. An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?

• A. 12 milliliters
• B. 24 milliliters
• C. 60 milliliters
• D. 120 milliliters

Correct answer: B

Rationale: First convert minutes to hours (1 hour * 60 minutes). Then, multiply the number of drops per minute (40 drops/minute) by the volume per drop (0.05 ml/drop) and by the conversion factor (60 minutes/hour) to find the total volume delivered: 40 drops/minute * 0.05 ml/drop * 60 minutes/hour = 24 milliliters.

6. What property of a substance refers to its ability to undergo a chemical change and form new substances?

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.
