Nursing Elites

1. What is the best summary of the passage?

• A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
• B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
• C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
• D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.

2. What is the author’s attitude toward vegetarianism?

• A. Scoffing
• B. Positive
• C. Cautious
• D. Uninterested

Correct answer: B

Rationale: The author presents a positive view of vegetarianism, citing benefits and supporting evidence.

3. What is the meaning of the word 'admonition' as used in the last paragraph?

• A. Permission
• B. Prescription
• C. Caution
• D. Verdict

Correct answer: C

Rationale: In this context, 'admonition' means a caution or warning, not permission, prescription, or verdict. The excerpt mentions that along with advising the elderly to move slowly and carefully, the CDC also recommends gentle exercise or physical therapy to strengthen muscles and improve balance. This advice aims to reduce the risk of falls and boost the self-esteem of older adults. Therefore, 'admonition' here refers to a precautionary counsel rather than granting permission, prescribing a treatment, or giving a verdict.

4. The author seems to?

• A. Oppose drinking alcohol
• B. Favor a strict diet
• C. Oppose regulation of personal habits
• D. Advocate moderation and balance

Correct answer: D

Rationale: The passage does not explicitly state the author's stance on alcohol consumption or dieting. However, the description of playing Bridge emphasizes qualities like time, effort, and attention to become proficient. This suggests that the author likely favors moderation and balance in one's approach to activities, rather than extremes like excessive drinking or strict dieting. Choice A is incorrect because the author does not express opposition to drinking alcohol. Choice B is incorrect as there is no indication of the author favoring a strict diet. Choice C is incorrect as there is no direct mention of opposing regulation of personal habits in the passage.

5. The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?

• A. A carpenter uses wood glue to fix a broken cabinet.
• B. A student buys a new notebook for upcoming classes.
• C. A chef sharpens knives before starting to cook.
• D. An athlete stretches before a game to avoid a potential injury.

Correct answer: D

Rationale: The correct analogy for the role of corrective lenses in helping aging eyes can be compared to an athlete stretching before a game. Just as stretching prepares an athlete's body to perform optimally and avoid injury during a game, corrective lenses help aging eyes adjust and focus properly due to the hardening and loss of elasticity in the eye lens. Choices A, B, and C do not align with the concept of preparing or adjusting to address a specific issue, unlike the use of corrective lenses for aging eyes.
