Correct Answer: B

Rationale: The correct answer is B: 'To draw together.' Contract means to reduce in size or draw together. Choices A, C, and D are incorrect because they suggest actions opposite to what contracting means. A: 'To expand,' C: 'To elongate,' and D: 'To dissolve' all indicate actions that involve increasing in size or breaking apart, which are the opposite of what contracting means.

Correct Answer: B

Rationale: The term 'distended' means swollen or enlarged. In this context, when the patient's veins are described as distended, it implies that they are expanded or swollen beyond their normal size, which can be a cause for worry due to potential health implications. Choice A ('Bleeding') is incorrect as 'distended' does not refer to bleeding but rather to being swollen. Choice C ('Pressure') is incorrect as 'distended' does not directly imply pressure but rather enlargement. Choice D ('Minuscule') is incorrect as 'distended' means the opposite of minuscule, indicating something enlarged or swollen.

Correct Answer: B

Rationale: The correct answer is 'Became.' In this sentence, we need the simple past tense 'became' to describe the action that occurred in the past. 'Become' (choice A) is incorrect as it is the base form of the verb and doesn't fit the sentence structure. 'Been' (choice C) is incorrect as it is the past participle and doesn't match the sentence context. 'Had become' (choice D) is unnecessary as the sentence doesn't require the past perfect tense.

Correct Answer: B

Rationale: Ominous means giving the impression that something bad or unpleasant is going to happen; threatening; inauspicious. This choice is correct as it accurately reflects the meaning of the term 'Ominous.' Choices A, C, and D are incorrect because they all suggest a lack of importance, danger, or threat, which is opposite to the actual meaning of 'Ominous.'

Correct Answer: A

Rationale: The correct answer is 'dilate.' Eye drops are used to dilate the pupils, meaning to widen or enlarge them, which is necessary for an eye exam to allow more light to enter the eye. 'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.
