Correct Answer: B

Rationale: The correct answer is B: 'Exhausted.' Lethargic describes a state of feeling sluggish, tired, and lacking energy, which aligns with being exhausted. Choice A, 'Energetic,' is the opposite of lethargic and does not fit the description. Choice C, 'Confused,' refers to a state of disorientation rather than physical tiredness. Choice D, 'Restless,' implies a state of agitation or inability to relax, which contrasts with the typical presentation of someone who is lethargic.

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: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

Correct Answer: A

Rationale: The correct answer is A: 'patient.' The correct spelling should be 'patient.' 'Physician,' 'sodium,' and 'recommended' are all spelled correctly. 'Physician' refers to a medical doctor, 'sodium' is a chemical element, and 'recommended' is the past tense of the verb 'recommend.' Therefore, the misspelled word in the sentence is 'patient.'

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.
