Correct Answer: B

Rationale: A blood vessel that is distended is swollen. Distention refers to the state of being stretched beyond normal limits, which can cause the blood vessel to expand and swell. The term 'distended' is often used to describe blood vessels that are enlarged or swollen due to various reasons such as increased blood pressure or blockages. Choice A, 'overturned,' does not relate to the enlargement or swelling of a blood vessel. Choice C, 'twisted,' describes a different condition where the blood vessel is coiled or rotated, not necessarily enlarged. Choice D, 'overlong,' does not accurately describe the state of a distended blood vessel; instead, it implies excessive length rather than enlargement.

Correct Answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.

Correct Answer: C

Rationale: Another word for the gonads would be the testes in males and ovaries in females. The gonads are the primary reproductive organs that produce gametes (sperm in males and eggs in females) and sex hormones. The term 'testes' specifically refers to the male gonads, while 'ovaries' would refer to the female gonads. Therefore, 'testes' is the correct answer as it directly relates to the male gonads, making choices A, B, and D incorrect.

Correct Answer: D

Rationale: An audit check is a process of reviewing and inspecting financial records, transactions, or processes to ensure accuracy and compliance with established guidelines. It involves examining information systematically and thoroughly to verify its completeness and reliability. Option D, "A review or inspection," best describes an audit check. Choices A, B, and C are incorrect as they do not relate to the process of auditing financial records for accuracy and compliance.

Correct Answer: C

Rationale: In this context, the word 'accountable' means responsible. The night nursing staff is responsible for those records, meaning they are the ones who are answerable and expected to ensure proper care and maintenance of the records. Choice A, 'Receptive,' does not fit the context as it means willing to listen or accept information. Choice B, 'Notorious,' means famous or well-known, usually for something negative, which is not the intended meaning here. Choice D, 'Preoccupied with,' means to be engrossed or absorbed in something, which does not convey the meaning of being responsible as intended in the sentence.
