1. What does Redundancy mean?

A. Deficiency
B. Surplus
C. Delicate
D. Abundance

Rationale: Redundancy means having more than is needed, making 'Surplus' the correct choice. The term does not relate to 'Deficiency' (lack), 'Delicate' (fragile), or 'Abundance' (plenty). In the context of this question, Redundancy refers to an excess or surplus of something.

2. What is another word for panacea?

A. Poison
B. Cure
C. Treatment
D. Remedy

Correct answer: B

Rationale: The correct answer is B: Cure. A panacea is a remedy or cure for all diseases. While 'poison' (choice A) is the opposite of a cure, 'treatment' (choice C) is a general approach to addressing an illness rather than a universal solution, and 'remedy' (choice D) is synonymous with cure but not as closely related to the concept of a universal remedy as 'cure'.

3. Choose the meaning of the word 'yaw' in the following sentence: 'The robotic arm may yaw too much and need adjusting.'

A. To gape open
B. To move up and down
C. To close tightly
D. To move side to side

Correct answer: D

Rationale: In this sentence, the term 'yaw' refers to a movement where the robotic arm moves side to side. The context suggests that the arm is exhibiting too much of this side-to-side movement and requires adjustment to rectify the issue. Choice A, 'to gape open,' is incorrect as 'yaw' does not imply opening. Choice B, 'to move up and down,' is incorrect as 'yaw' specifically refers to side-to-side movement. Choice C, 'to close tightly,' is incorrect as it does not relate to the movement described in the sentence.

4. What is the CORRECT CONTRACTION for 'will not'?

A. Won't
B. Willn't
C. Wouldn't
D. Will'nt

Correct answer: A

Rationale: The correct contraction for 'will not' is 'won't'. 'Willn't' (Choice B) is not a standard contraction in English. 'Wouldn't' (Choice C) is the contraction for 'would not,' not 'will not.' 'Will'nt' (Choice D) is not a recognized contraction in English. Therefore, 'won't' is the correct choice as the contraction for 'will not.'

5. The nurse noted in the chart, 'The patient is lethargic.' How was the patient behaving?

A. Pacing the halls
B. Difficult to arouse
C. Shaking uncontrollably
D. Not responding to pain

Correct answer: B

Rationale: The correct answer is B: 'Difficult to arouse.' 'Lethargic' is a medical term used to describe a state of drowsiness or lack of energy, making the patient difficult to arouse. Choices A, C, and D describe different behaviors that are not indicative of lethargy. A patient who is pacing the halls is more likely to be agitated, while shaking uncontrollably may suggest tremors or seizures. Not responding to pain indicates a lack of reaction to painful stimuli but does not directly reflect being lethargic.
