Which sentence uses 'etc.' grammatically correct?

Correct Answer: A

Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.

Correct Answer: C

Rationale: The correct answer is 'C: Hold fast.' 'Adhere' means to stick firmly to something, which aligns with 'hold fast.' Choices A, B, and D are incorrect. 'Remain intact' does not capture the idea of sticking to something, 'loosen' is the opposite of 'adhere,' and 'position next to' does not convey the sense of sticking or clinging.

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: A

Rationale: In pharmacology, understanding vocabulary is crucial for effective communication and comprehension of drug actions. The question asks for another word for "ANTICIPATE." The correct answer is A) Predict. Anticipate and predict both involve foreseeing or expecting something to happen. In pharmacology, predicting outcomes of drug interactions or patient responses is essential for safe and effective medication administration. Option B) Evaluate is incorrect because it means to assess or judge, not to anticipate or predict. Evaluation comes after the anticipation or prediction phase. Option C) Compare is incorrect as it means to note similarities and differences between two or more things. It does not directly relate to anticipating or predicting future events. Option D) Forestall is incorrect because it means to prevent or hinder something from happening, which is different from anticipating or predicting. Forestalling is a proactive measure to stop something from occurring. Educationally, knowing synonyms in pharmacology enhances communication among healthcare professionals. Being able to anticipate or predict drug effects or patient responses is a critical skill in providing safe and effective care. Understanding the nuances of vocabulary helps pharmacology students and professionals accurately convey information and make informed decisions in their practice.

Correct Answer: A

Rationale: The correct answer is 'Prefix.' A prefix is a word part that is placed before a root word to modify its meaning. In this case, a prefix changes the meaning of the root word. Choice B, 'Affix,' is a broader term that includes prefixes, suffixes, and infixes. Choice C, 'Suffix,' is a word part placed after a root word to modify its meaning, not before. Choice D, 'Vocab,' is unrelated to the word part placed before a word.
