Correct Answer: B

Rationale: The correct answer is B: 'Given through or affecting the mouth.' Oral medications are those that are taken by mouth.
Choice A is incorrect as 'Through the skin' refers to something being absorbed through the skin, not through the mouth.
Choice C, 'Injected,' is incorrect as oral administration does not involve injection but rather ingestion.
Choice D, 'Absorbed through digestion,' is partially correct in that oral medications are indeed absorbed through the digestive system, but the term 'oral' specifically refers to the mouth in this context.

Correct Answer: B

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach.
Therefore, in this context, the larynx is the most appropriate term.

Correct Answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious means causing great harm or damage.
Choice A, 'Harmless,' is the opposite of pernicious.
Choice C, 'Infectious,' refers to the ability of a disease to spread.
Choice D, 'Helpful,' is also the opposite of pernicious and does not capture the negative connotation associated with the term.

Correct Answer: B

Rationale: The correct answer is B: 'Regretful.' Contrite means feeling regret or remorse.
Choice A, 'Guilty,' does not fully capture the meaning of contrite as it implies a judgement of culpability rather than a feeling of remorse.
Choice C, 'Shameful,' is incorrect as it focuses on the emotion of shame rather than regret.
Choice D, 'Pleased,' is the opposite of what contrite means, as it signifies satisfaction or happiness, which is contradictory to feeling regretful or remorseful.

Correct Answer: B

Rationale: The correct answer is B: '
To expel feces.' Defecate refers to the act of eliminating solid waste from the body.
Choice A, '
To retain feces,' is incorrect as defecation involves getting rid of feces.

Choices C and D, '
To eliminate fluid' and '
To excrete mucus,' are also incorrect as they do not accurately define the term 'defecate.'
