Question 1 of 5
What does it mean if something is distended?
Correct Answer: B
Rationale: Step 1: Define distended - means swollen or enlarged beyond normal size. Step 2: Understand opposite meanings - shrunken means reduced in size, not enlarged. Step 3: Understand related terms - narrow and flattened refer to dimensions, not enlargement. Step 4: Conclusion - distended means swollen, making choice B the correct answer.
Question 2 of 5
What does 'Parameter' mean?
Correct Answer: B
Rationale: Step-by-step rationale: 1. A parameter is a characteristic or constant factor that defines a system. 2. It is not a constant variable (A) as it is not subject to change within a given context. 3. It is not a measurable limit (C) but rather a defining aspect of a system. 4. It is not a calculated risk (D) as it is not related to potential outcomes, but rather a fixed element. In summary, choice B is correct as a parameter is a specific, unchanging factor that characterizes a system, while the other choices do not accurately define the term.
Question 3 of 5
A synonym is a word _____ a meaning similar to another word.
Correct Answer: A
Rationale: The correct answer is A: that has. In this sentence, "a word" is the subject and "that has" is the relative pronoun clause that connects the subject to the predicate "a meaning similar to another word." The use of "that has" correctly indicates the relationship between the word and its meaning. Choices B, C, and D are incorrect because "which gives" and "which has" do not appropriately connect the word to the intended meaning in the sentence. The use of "that gives" is also incorrect as it suggests the word is actively providing a meaning, which is not the intended meaning in this context.
Question 4 of 5
Another word for UNDER OBSERVATION is?
Correct Answer: C
Rationale: The correct answer is C: Surveillance. Under observation means being watched or monitored, which aligns with the definition of surveillance. A: Cognition refers to mental processes, not observation. B: Isolation means being separated or detached, not observed. D: Assessment involves evaluating or judging, not solely observing. Therefore, C is the best fit for the given phrase.
Question 5 of 5
What is the meaning of exacerbate?
Correct Answer: B
Rationale: The correct answer is B: To make worse. Exacerbate means to increase the severity or intensity of something negative. This is the opposite of choice A, which means to lessen in intensity. Choice C, to neutralize, is incorrect because exacerbate does not imply any form of neutralization. Choice D, to control, is also wrong as exacerbate does not involve managing or regulating a situation. Overall, the correct answer, B, best captures the meaning of exacerbate by indicating a worsening or aggravation of a situation.
