1. What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?

Correct answer: C

Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.

2. What is the best description for the term doleful?

Correct answer: D

Rationale: The term 'doleful' is best described as feeling or expressing sorrow or sadness. 'Downcast' aligns with this meaning as it refers to having a dejected or low spirit, which matches the nature of doleful. Options A, B, and C do not directly relate to the sense of sadness or sorrow that doleful conveys. 'Unwell' means in poor health, 'deprived' means lacking something essential, and 'conceited' means having an excessively favorable opinion of oneself, none of which capture the essence of doleful.

3. Did the interns contravene the doctor's orders?

Correct answer: B

Rationale: The correct answer is 'B: Disregard.' Contravene means to violate or disregard rules or orders. In this context, the question is asking whether the interns went against or disobeyed the doctor's orders. Choices 'A: Follow,' 'C: Exceed,' and 'D: Respect' do not align with the meaning of contravene in this context. Following, exceeding, or respecting the doctor's orders would mean the interns did not contravene them.

4. The plumber used a flexible tube to open up the curved pipe.

Correct answer: C

Rationale: The term 'flexible' accurately describes the type of tube used in the given context. A 'solid' tube would not have been suitable for navigating a curved pipe as it is not pliable. 'Rigid' implies stiffness and inflexibility, making it unsuitable for the task. 'Perforated' means pierced with holes, which is unrelated to the plumber's task of opening up a curved pipe.

5. Which statement indicates that the individual feels EMPATHY for the patient?

Correct answer: A

Rationale: Choice A, 'I am also new to this town, so I understand how lost he feels here,' demonstrates empathy towards the patient by showing the ability to relate to and understand the patient's feelings and experiences. Empathy involves understanding and sharing the feelings of another person, which is evident in this statement as the individual acknowledges and connects with the patient's emotional state. Choice B focuses on the urgency of addressing symptoms but lacks the emotional connection present in an empathetic response. Choice C emphasizes following a treatment plan without addressing the patient's emotional state. Choice D displays a lack of empathy by suggesting that the patient is exaggerating their pain for attention, showing a judgmental rather than understanding attitude.
