Nursing Elites

1. Which statement is not listed as a detail within the passage?

• A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
• B. The signal has a characteristic record called the electrocardiogram.
• C. The 'wave of excitation' starts at the SA node.
• D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.

Correct answer: A

Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.

2. 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.

3. What is the meaning of the word consensus as it is used in the last paragraph about Barefoot Running?

• A. Investigation.
• B. Purpose.
• C. Trepidation.
• D. Unanimity.

Correct answer: D

Rationale: "Consensus" refers to a general agreement or unanimity among individuals, particularly regarding the safety and effectiveness of barefoot running. The passage discusses differing opinions on this subject, indicating that there is not a unanimous agreement. Thus, choice D accurately captures the meaning of "consensus" within the context of the discussion.

4. What conclusion can you draw from the first sentence of the passage?

• A. Osteoporosis is more common than anyone previously imagined.
• B. The media give a lot of overall coverage to osteoporosis.
• C. Only women are at high risk for developing bone thinning.
• D. Thinning bones is not considered a serious medical problem.

Correct answer: B

Rationale: The correct answer is B. The first sentence suggests that osteoporosis receives significant media coverage, indicating that the media gives a lot of overall coverage to the issue. This conclusion can be drawn as the passage mentions how osteoporosis is a major health concern for women and is widely covered in newspapers and television commercials. Choice A is incorrect because the passage does not mention the prevalence of osteoporosis compared to previous estimates. Choice C is incorrect as the passage highlights that men are being overlooked in terms of bone thinning concerns. Choice D is incorrect as the passage emphasizes the seriousness of bone thinning and the need for preventive measures.

5. As used in the second paragraph, what does the term ubiquitous mean?

• A. Indigenous
• B. Often ignored
• C. Found everywhere
• D. Dangerous

Correct answer: C

Rationale: The correct answer is C: 'Found everywhere.' Ubiquitous in this context means widespread presence. In the provided extract, it is mentioned that MRSA bacteria have become ubiquitous not only in hospitals but also in various other settings, indicating they are found everywhere. Choice A, 'Indigenous,' is incorrect as it refers to something native or originating from a specific place, which is not the intended meaning in the context. Choice B, 'Often ignored,' is incorrect as ubiquitous means something that is widely present, not something that is ignored. Choice D, 'Dangerous,' is incorrect as ubiquitous does not directly imply danger, but rather the widespread presence of something.
