1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. What does the quoted word 'equilibrium' mean in the following sentence?

A. Ability to speak
B. Sense of taste
C. Sense of balance
D. Ability to swallow

Correct answer: C

Rationale: The correct answer is C: 'Sense of balance.' In the sentence provided, 'equilibrium' refers to a state of physical balance or stability. The client lost his balance when he woke up, indicating a loss of stability or equilibrium. Choices A, B, and D are incorrect because 'equilibrium' specifically refers to balance, not the ability to speak, sense of taste, or ability to swallow.

3. Which term refers to the surgical removal of an organ's contents?

A. Vivisection
B. Amputation
C. Evisceration
D. Augmentation

Correct answer: C

Rationale: The correct answer is C, 'Evisceration.' Evisceration specifically refers to the surgical removal of an organ's contents, for example, the removal of abdominal contents during certain surgical procedures. Vivisection (A) involves performing experiments on live animals, amputation (B) is the removal of a limb, and augmentation (D) is the process of increasing the size, value, or quality of something. Therefore, in the context of surgical procedures, evisceration best fits the description of removing an organ's contents.

4. A truculent patient is ______

A. Friendly
B. Argumentative
C. Cooperative
D. Passive

Correct answer: B

Rationale: A truculent patient is characterized by being argumentative or hostile. This type of patient tends to be confrontational and uncooperative, often displaying aggressive behavior. Choice A, 'Friendly,' is incorrect as truculent patients are not known for their friendliness. Choice C, 'Cooperative,' is also incorrect as truculent patients are the opposite of cooperative. Choice D, 'Passive,' is incorrect because truculent patients are not passive but rather assertive and combative.

5. The man's heart attack scared him badly and he decided to have a regular check-up.

A. severely
B. badly
C. intensely
D. profoundly

Correct answer: B

Rationale: In this context, 'badly' is the appropriate adverb to describe the intensity of the fear caused by the heart attack. 'Severely' and 'intensely' do not convey the same meaning in this sentence. 'Profoundly' refers more to depth or seriousness of an emotion, which doesn't fit the context of fear caused by a heart attack.
