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: The correct answer is B, 'Wide open'. Gaping refers to something being wide open, not partially closed (choice A), narrow (choice C), or sealed (choice D). In the context of the question, 'Gaping' describes something that is open widely.

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: C

Rationale: The word 'ephemeral' means lasting for a very short time. In this context, a vacationer feeling that their trip to Hawaii was too short implies that they found it to be brief or fleeting, making 'ephemeral' the most suitable choice among the options provided. Ponderous means slow and clumsy; salacious means obscene or lustful; erudite means showing great knowledge or learning. These words do not convey the idea of brevity or shortness, unlike 'ephemeral,' which perfectly fits the scenario described.

Correct Answer: B

Rationale: The correct answer is B. Distal means further away from the point of attachment. This term is commonly used in anatomy to describe the location of a body part relative to the point of attachment or the trunk. Choice A is incorrect because it describes the term Proximal, which means closer to the point of attachment. Choice C is incorrect as it describes the term Medial, which means toward the middle of the body. Choice D is incorrect as it describes the term Superficial, which means on or near the surface.
