Correct Answer: B

Rationale: The correct answer is B, 'Emetic.' An emetic is a medication specifically designed to induce vomiting. This helps the body expel toxic substances or clear the stomach. Choice A, 'Laxative,' aids in relieving constipation by promoting bowel movements, not inducing vomiting. Choice C, 'Vaccine,' is a substance used to stimulate the immune system against specific diseases, not to induce vomiting. Choice D, 'Analgesic,' refers to a medication used to relieve pain, not to induce vomiting. Therefore, options A, C, and D are incorrect in the context of inducing vomiting.

Correct Answer: C

Rationale: The term 'PROGNOSIS' refers to the expected outcome or likelihood of recovery after a specific treatment or illness. In this context, the word 'PROGNOSIS' directly relates to the expected outcome following the treatment, making choice C - Expected outcome - the correct answer. Choices A, B, and D are incorrect because 'Compliance' refers to following instructions, 'Range of motion' relates to the extent of movement in a joint, and 'Conclusion' is a summary or final decision, none of which captures the meaning of 'PROGNOSIS.'

Correct Answer: B

Rationale: The correct answer is B: 'Straightforward.' Guileless means innocent, sincere, and without deceit. It describes someone who is honest and straightforward in their actions and speech. Choices A, C, and D are incorrect. 'Deceptive' means misleading or dishonest, 'Complex' means having many intricate parts, and 'Untrustworthy' means not reliable or trustworthy, all of which are opposite in meaning to guileless.

Correct Answer: A

Rationale: The correct answer is A: 'Complaining.' Querulous means to be habitually complaining or whining. It is characterized by a tendency to find fault or raise petty objections. This behavior aligns with the definition of being querulous. Choices B, C, and D are incorrect as they do not reflect the meaning of querulous. Sleeping, shouting, or crying are not behaviors typically associated with being querulous.

Correct Answer: B

Rationale: The term 'Precept' refers to a guiding principle rather than just a rule, habit, or punishment. A precept is a general rule or principle guiding behavior, making choice B the correct answer. Choices A, C, and D are incorrect because a precept is more than just a simple rule, habit, or punishment; it encompasses a fundamental guiding principle that influences actions and decisions.
