Nursing Elites

1. Select the meaning of the word 'PRN' in the sentence: 'The nurse gave the patient a PRN medication.'

• A. Pinpoint
• B. Relocate
• C. Eradicate
• D. Reduce

Correct answer: D

Rationale: 'PRN' is a medical abbreviation that stands for 'pro re nata,' meaning 'as needed.' In this context, the medication is given to reduce symptoms as they arise. Choice A, 'Pinpoint,' does not align with the meaning of 'PRN.' Choices B and C, 'Relocate' and 'Eradicate,' are unrelated to the concept of 'as needed' medications.

2. What is the author's main argument in the passage on the Electoral College?

• A. The Electoral College ensures that all states have a say in elections.
• B. The Electoral College is outdated and needs reform.
• C. The Electoral College should be abolished.
• D. The Electoral College was created to favor larger states.

Correct answer: B

Rationale: The correct answer is B: 'The Electoral College is outdated and needs reform.' The passage discusses the Electoral College system, highlighting its complexities and the discrepancy between the popular vote and electoral vote outcomes. It mentions the confusion and the case of the 2000 election where the popular vote winner did not become president. The main argument is that the system is outdated and requires reforms to align with modern democratic principles. Choice A is incorrect as the passage does not focus on ensuring all states have a say but rather on the need for reform. Choice C is not the main argument presented in the passage; while the passage mentions confusion, it does not explicitly call for abolition. Choice D is incorrect as the passage does not state that the Electoral College was created to favor larger states; instead, it discusses the allocation of electoral votes based on Congressional representation and population.

3. What does the author suggest about the Earth's tilt in the passage on Daylight Savings Time?

• A. The Earth's tilt has no effect on the seasons.
• B. The Earth's tilt affects the amount of sunlight different areas receive.
• C. The Earth's tilt is constant throughout the year.
• D. The Earth's tilt changes dramatically during the seasons.

Correct answer: B

Rationale: The author suggests that the Earth's tilt affects the amount of sunlight different areas receive, influencing the seasons. The passage explains how the tilt of the Earth towards the sun results in different regions receiving varying amounts of sunlight, leading to the existence of seasons. This tilt causes regions near the equator to receive more sunlight consistently, while the Poles experience periods of constant darkness or sunlight, creating different seasons. Choices A, C, and D are incorrect because the passage clearly states that the Earth's tilt influences sunlight distribution and subsequently impacts the seasons.

4. As the frequency of a sound wave increases, what else is true?

• A. Its wavelength decreases.
• B. Its wavelength increases.
• C. Its amplitude decreases.
• D. Its amplitude increases.

Correct answer: A

Rationale: The correct answer is A: 'Its wavelength decreases.' The frequency and wavelength of a sound wave are inversely proportional. As the frequency of a sound wave increases (more oscillations per second), its wavelength decreases. This relationship is described by the formula: Speed of Sound = Frequency x Wavelength. Therefore, to maintain the speed of sound constant, when the frequency increases, the wavelength must decrease. Choices B, C, and D are incorrect because an increase in frequency does not lead to an increase in wavelength or changes in amplitude.

5. Which of the following is a characteristic of an exothermic reaction?

• A. It absorbs heat
• B. It releases heat
• C. It remains neutral
• D. It requires energy input

Correct answer: B

Rationale: An exothermic reaction is characterized by the release of heat. During an exothermic reaction, energy is released in the form of heat to the surroundings, resulting in a temperature increase. This distinguishes it from endothermic reactions, which absorb heat from the surroundings. Choice A is incorrect because exothermic reactions do not absorb heat; instead, they release heat. Choice C is incorrect as exothermic reactions do not remain neutral; they involve a net release of energy. Choice D is incorrect as exothermic reactions do not require energy input; instead, they release energy.
