Rationale: Another word for the collarbone is the clavicle. The term 'clavicle' is commonly used in anatomy to refer to this bone that connects the arm to the rest of the body's skeleton. Choice A, 'cloaca,' is incorrect as it refers to a bodily cavity that serves as the opening for the intestinal, genital, and urinary tracts in many vertebrates. Choice B, 'cannula,' is incorrect as it refers to a tube inserted into a vein or body cavity to administer medication or drain fluid. Choice D, 'clavier,' is incorrect as it refers to a keyboard musical instrument.

Correct Answer: C

Rationale: The word 'formulaic' means following a formula or set pattern. Therefore, something that is systematic and follows a structured plan can also be described as formulaic. Choices A, B, and D are incorrect. 'Involuntary' means done without will or conscious control, 'universal' means affecting, or done by all people or things in the world, and 'manual' means operated or done by hand rather than automatically or electronically. Therefore, 'formulaic' is the most accurate synonym in the given context.

Correct Answer: D

Rationale: Unruffled means calm and not agitated. The word 'composed' also means calm and collected, making it the correct synonym in this context. 'Concerned' (choice A) means worried or anxious, 'wholesome' (choice B) means promoting health and well-being, and 'tedious' (choice C) means boring or monotonous, making them all incorrect choices.

Correct Answer: C

Rationale: BID stands for 'bis in die' in Latin, which translates to 'twice a day' in English. Therefore, when medication is prescribed to be given BID, it should be administered twice daily. Choice A, 'as needed,' does not correspond to a specific dosing frequency like BID. Choice B, 'every two hours,' indicates a different dosing schedule that is more frequent than BID. Choice D, 'with food,' refers to the administration instructions related to meals and is not the correct interpretation of BID.

Correct Answer: A

Rationale: A synthetic drug is one that is artificially created in a laboratory setting rather than occurring naturally. The term 'man-made' accurately describes this process.

'Atypical' means unusual or not typical, which doesn't directly relate to how synthetic drugs are made. 'Futile' means pointless or ineffective, which is not a characteristic of synthetic drugs.
