Nursing Elites

1. If a patient's condition is deteriorating, what is happening?

• A. They are improving
• B. They are getting worse
• C. They are stable
• D. They are recovering

Correct answer: B

Rationale: When a patient's condition is deteriorating, it means they are getting worse. This indicates a decline or worsening in their health status, requiring immediate attention or intervention. Choice A is incorrect because 'improving' means the opposite of deteriorating. Choice C is incorrect as 'stable' means there is no significant change. Choice D is incorrect as 'recovering' means getting better, which is the opposite of deteriorating.

2. Which gland regulates the body's metabolic rate?

• A. Pituitary gland
• B. Thyroid gland
• C. Adrenal gland
• D. Pineal gland

Correct answer: B

Rationale: The thyroid gland is responsible for regulating the body's metabolic rate by producing hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in controlling the body's metabolism, affecting processes like growth, energy production, and temperature regulation. The pituitary gland is known as the 'master gland' but primarily regulates other endocrine glands by releasing hormones that stimulate their function. The adrenal gland is responsible for producing hormones like adrenaline and cortisol, which are involved in the body's response to stress. The pineal gland secretes melatonin, a hormone that regulates sleep-wake cycles and circadian rhythms, but is not directly involved in regulating metabolic rate.

3. Which sound waves have a higher pitch?

• A. Those waves that are closer together
• B. Those waves that are farther apart
• C. Those waves that travel a long distance
• D. Those waves that travel a short distance

Correct answer: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.

4. Cobalt-60 has a half-life of 5 years. If you start with 20 g of cobalt-60, how much is left after 10 years?

• A. 15 g
• B. 10 g
• C. 5 g
• D. 2.5 g

Correct answer: C

Rationale: Cobalt-60's half-life of 5 years means that after 5 years, half of the initial amount remains. Therefore, after 10 years, a quarter (half of a half) of the initial amount will remain. Starting with 20 g, after 10 years, 5 g of cobalt-60 will be left. Choice A (15 g) is incorrect because it assumes a linear decrease, not considering the exponential decay characteristic of radioactive substances. Choice B (10 g) is incorrect as it overlooks that after 10 years, more decay has occurred. Choice D (2.5 g) is incorrect as it represents only an eighth of the initial amount after 10 years, not a quarter.

5. What does the author of the passage on the Electoral College seem to suggest?

• A. The Electoral College should be abolished.
• B. The Electoral College works as intended.
• C. The Electoral College needs reform.
• D. The Electoral College confuses voters.

Correct answer: B

Rationale: The correct answer is B. The author of the passage suggests that the Electoral College works as intended. Despite acknowledging its confusing nature and the possibility of results differing from the popular vote, the author highlights that the founding fathers had a purpose behind its design. Therefore, the Electoral College is viewed as functioning as intended. Choice A is incorrect because the author does not advocate for abolishing the Electoral College. Choice C is incorrect as there is no explicit mention of the need for reform. Choice D is incorrect as the author does not focus on the confusion caused to voters but rather on the system's original purpose.
