1. Select the meaning of the word 'dilation' in the sentence: 'The laboring mother was at 50% dilation.'

A. Blood pressure
B. Cervical opening
C. Birth process
D. Exhumation

Correct answer: B

Rationale: In the context provided, 'dilation' refers to the widening or opening of the cervix during labor as the woman progresses towards childbirth. Choice A, 'Blood pressure,' is incorrect as dilation does not relate to blood pressure. Choice C, 'Birth process,' is too broad and does not specifically define the term 'dilation.' Choice D, 'Exhumation,' is unrelated and does not fit the context of the sentence.

2. Identify the correct sentence structure.

A. The cat sleeping on the mat
B. The cat is sleeping on the mat
C. The mat that the cat is sleeping on
D. Sleeping on the mat is the cat

Correct answer: B

Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.

3. 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.

4. Which bone is shorter in the forearm?

A. Humerus
B. Radius
C. Scapula
D. Fibula

Correct answer: B

Rationale: The correct answer is B: Radius. The forearm consists of two long bones: the radius and the ulna. The radius is located on the thumb side of the forearm and is shorter than the ulna, which is on the pinky side. The humerus is the bone located in the upper arm, the scapula is the shoulder blade bone, and the fibula is a bone in the lower leg. Therefore, they are not the shorter bone in the forearm.

5. What does the word 'principally' mean?

A. Mostly
B. Clearly
C. In our opinion
D. Royally

Correct answer: A

Rationale: The correct answer is A: 'Mostly.' The word 'principally' means mainly or mostly. It is used to describe something that is primarily or predominantly true in a given context. Choice B, 'Clearly,' is incorrect as it does not reflect the primary meaning of the word. Choice C, 'In our opinion,' is incorrect as it does not capture the essence of 'principally.' Choice D, 'Royally,' is incorrect as it does not align with the definition of the word.
