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 If a theory is obsolete, what is true of it?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B. Outdated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Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant.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D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.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 'occluded' mean in the following sentence? The nurse reported that the patient's circulation to that foot was 'occluded'.

A. Normal
B. Impaired
C. Inadequate
D. Obstructed

Correct answer: D

Rationale: The correct answer is D, 'Obstructed.' 'Occluded' means blocked or obstructed, indicating that the circulation to the foot was hindered. Choices A, B, and C are incorrect because 'occluded' does not mean normal, impaired, or inadequate but rather obstructed.

3. A surgeon who is adroit might be described as ______.

A. Careless
B. Skillful
C. Inexperienced
D. Lazy

Correct answer: B

Rationale: The word 'adroit' means skillful or proficient. A surgeon who is adroit would be highly skilled and proficient in their work. Therefore, the most appropriate description for a surgeon who is adroit is 'skillful.' Choices A, C, and D are incorrect because they do not reflect the positive attribute associated with being adroit.

4. Which word is not spelled correctly in the context of this sentence? 'The nurse went from room to room looking for the missing patient.'

A. patient
B. form
C. nurse
D. missing

Correct answer: B

Rationale: The correct answer is 'B' because 'form' is misspelled, it should be 'from'. In the given sentence, 'form' is incorrect as it should be 'from' to indicate movement from one place to another. The other choices ('patient,' 'nurse,' 'missing') are spelled correctly and are relevant in the context of the sentence.

5. What does 'Contour' mean?

A. Flat area
B. Shape or outline of something
C. Volume of a structure
D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.
