1. In the majority culture of America, coughing, sweating, and diarrhea are symptoms of an illness. For some individuals of Mexican-American origin, however, these symptoms are a normal part of living. The nurse recognizes that this is true, probably because Mexican-Americans:

A. have less efficient immune systems and are often ill.
B. consider these symptoms a part of normal living, not symptoms of ill health.
C. come from Mexico where coughing is normal and healthy.
D. are usually in a lower socioeconomic group and are more likely to be sick.

Correct answer: B

Rationale: In Mexican-American culture, coughing, sweating, and diarrhea are often considered normal bodily functions and not necessarily indicative of illness. This cultural perspective shapes their understanding of health and illness, leading them to view these symptoms differently than the majority culture in America. Choice A is incorrect because it generalizes Mexican-Americans as having less efficient immune systems, which is not supported by evidence. Choice C is incorrect as it oversimplifies by attributing the perception solely to coming from Mexico. Choice D is incorrect as it makes unwarranted assumptions about the socioeconomic status and health status of Mexican-Americans.

2. 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.

3. What does 'Parameter' mean?

A. A constant variable
B. A characteristic or constant factor
C. A measurable limit
D. A calculated risk

Correct answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.

4. What is 80% of 55?

A. 40
B. 44
C. 39
D. 45

Correct answer: B

Rationale: To find 80% of a number, you multiply the number by 0.8. Therefore, 80% of 55 is calculated as 0.8 × 55 = 44. Choice A (40), choice C (39), and choice D (45) are incorrect as they do not represent the correct calculation for 80% of 55.

5. What is the opposite of -3?

A. -6
B. 3
C. 0
D. 6

Correct answer: B

Rationale: The opposite of a number is the number that, when added to it, results in zero. In this case, the opposite of -3 is a number that, when added to -3, gives 0. Therefore, the opposite of -3 is 3, as -3 + 3 = 0. Choice A, -6, is incorrect because -3 + (-6) = -9, not zero. Choice C, 0, is the additive inverse of 0, not -3. Choice D, 6, is also incorrect as -3 + 6 = 3, not zero.
