Correct Answer: A

Rationale: The correct answer is A, 'Toxic.' 'Injurious' means harmful or likely to cause injury, similar to 'toxic.' Choices B, C, and D are incorrect because 'palatable' means pleasant to taste, 'amenable' means cooperative or willing to agree, and 'harmless' means not causing harm.

Correct Answer: D

Rationale: The correct answer is 'Ventral' because it specifically refers to the lower surface of a structure. 'Inferior' means below in position, 'Transverse' means situated across something, and 'Dorsal' refers to the upper side or back of a structure, making them incorrect in the context of the lower surface of a structure.

Correct Answer: B

Rationale: The word 'ritualistic' is an adjective that describes actions or behaviors performed in a habitual or symbolic manner, often resembling a ritual. In this context, it best describes the patient's behavior of repeatedly and meticulously arranging food on the plate. 'Formal' (Choice A) does not capture the habitual or symbolic aspect of the behavior. 'Formalizing' (Choice C) is a verb form and does not describe the behavior itself. 'Ritual' (Choice D) is a noun and does not fit as well here since the question is asking for an adjective to describe the behavior.

Correct Answer: C

Rationale: The correct answer is C: 'Not affected.' In the context provided, 'impervious' means that the client is not affected by pain. Choices A, B, and D are incorrect because they do not accurately capture the meaning of 'impervious' in this context. 'Coping well' implies dealing with pain effectively, 'enjoying' does not reflect being unaffected by pain, and 'very sensitive' is the opposite of what 'impervious' means.

Correct Answer: C

Rationale: The correct answer is 'Democratic.' A 'Democratic' leadership style involves the leader being open to new ideas and thoughts from the group and encourages group participation in decision-making. This style promotes collaboration, communication, and inclusivity in decision-making processes. 'Laissez-faire' leadership is characterized by a hands-off approach with minimal guidance or direction. 'Autocratic' leadership is where the leader makes decisions without much input from the group. 'Direct' leadership is not a widely recognized leadership style in this context.
