Correct Answer: A

Rationale: Regulations refer to rules or directives established by authorities to govern conduct or actions. Therefore, the correct answer is A - 'Rules for Conduct.' Choice B, 'Official Standards,' is incorrect as regulations go beyond just setting standards to include specific rules for behavior. Choice C, 'Personal Guidelines,' is incorrect as regulations are not individualized but are generally applicable rules. Choice D, 'Suggestions,' is incorrect as regulations are mandatory and carry legal weight, unlike suggestions which are optional and not binding.

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.

Correct Answer: B

Rationale: The correct answer is 'B: Entering into a body part.' 'Invasive' refers to something that invades or penetrates into a body part. Choice A, 'Harmless,' is incorrect as invasive implies a negative impact. Choice C, 'Mildly irritating,' is incorrect as invasive implies a more serious intrusion. Choice D, 'Non-penetrative,' is incorrect as invasive specifically denotes penetration or entry.

Correct Answer: B

Rationale: The correct answer is B: 'Regretful.' Contrite means feeling regret or remorse. 'Guilty' (A) refers to being responsible for a wrongdoing, not necessarily feeling remorseful. 'Shameful' (C) means feeling ashamed, which is related but not the same as feeling regret. 'Pleased' (D) means feeling satisfied or happy, which is the opposite of contrite.

Correct Answer: B

Rationale: The correct answer is B: 'Vague.' Nebulous means something that is vague or unclear. Choices A, C, and D are incorrect because nebulous is the opposite of clear, distinct, and complex. Nebulous refers to something lacking definite form or limits, making it difficult to understand or perceive clearly.
