Nursing Elites

1. What is the meaning of the word 'sterile' as it is used in the second paragraph?

• A. free of bacteria
• B. healthy
• C. delicious
• D. impotent

Correct answer: A

Rationale: In the context provided, 'sterile' means free of bacteria. The text mentions that raw foods are not sterile and can be a common source of foodborne illnesses due to contamination with harmful bacteria. 'Healthy' (choice B) is incorrect as the term 'sterile' specifically refers to the absence of bacteria, not overall health. 'Delicious' (choice C) is irrelevant to the context of bacteria contamination. 'Impotent' (choice D) is also incorrect as it does not relate to the concept of being free from bacteria.

2. 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.

3. The word lethargy as used in the second paragraph of the passage can best be defined as ___________.

• A. Sluggishness
• B. Irritability
• C. Energy
• D. Starvation

Correct answer: A

Rationale: In this context, 'lethargy' refers to a state of sluggishness or lack of energy. The passage mentions that people with seasonal affective disorder (SAD) struggle with lethargy and chronic fatigue, impairing their daily lives. Therefore, the correct definition of 'lethargy' in this context is 'sluggishness.' Choice B, 'Irritability,' is incorrect as lethargy refers more to a lack of energy than to being irritable. Choice C, 'Energy,' is the opposite of lethargy. Choice D, 'Starvation,' is unrelated to the definition of lethargy in this context.

4. What is the meaning of the word 'shifts' as used in the third paragraph?

• A. Alterations
• B. Stints
• C. Removals
• D. Transfers

Correct answer: A

Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.

5. What is the meaning of the word 'ideal' as it is used in the first paragraph?

• A. thoughtful
• B. confined
• C. hostile
• D. perfect

Correct answer: D

Rationale: In this context, 'ideal' means perfect. The human body provides a perfect environment for many microbes, as stated in the extract. It is the immune system's role to keep these microbes out or destroy them. The other choices are incorrect: 'thoughtful' does not fit the context of the sentence, 'confined' and 'hostile' are not synonymous with 'ideal' in this context.
