1. Select the meaning of the word 'reflex' in the sentence: 'The typical patellar reflex takes only 50 milliseconds between the initial tap and the leg extension.'

A. Replication
B. Convulsion
C. Reaction
D. Stretching

Correct answer: C

Rationale: In the context of the sentence, the word 'reflex' indicates a quick, automatic response by the body to a stimulus. The patellar reflex, also known as the knee-jerk reflex, involves the leg extending in response to a tap on the patellar tendon. Therefore, the word 'reaction' aligns closely with the nature of the patellar reflex in terms of a rapid and involuntary response. Choices A, B, and D are incorrect: 'Replication' does not capture the concept of a bodily response, 'convulsion' implies a sudden and uncontrollable movement which is not specific to the nature of the patellar reflex, and 'stretching' does not encompass the automatic and rapid nature of a reflex action.

2. A stye is an infection of the ___________.

A. eyelid
B. eardrum
C. nostril
D. scalp

Correct answer: A

Rationale: A stye is an infection that occurs at the base of an eyelash or on the eyelid. It is typically caused by a bacterial infection, leading to redness, swelling, and sometimes discomfort in the affected area. Choices B, C, and D are incorrect because a stye specifically refers to an infection of the eyelid area, not the eardrum, nostril, or scalp.

3. A symptom that is transitory is ___________.

A. short-lived
B. damaging
C. fluctuating
D. degenerating

Correct answer: A

Rationale: A symptom that is transitory is short-lived. It appears temporarily and does not persist for an extended period of time. This term indicates that the symptom is not permanent or continuous but rather temporary or fleeting.\nChoice B, damaging, is incorrect as transitory refers to the duration of the symptom, not its impact. Choice C, fluctuating, is incorrect as it implies the symptom varies in intensity, not necessarily in duration. Choice D, degenerating, is incorrect as it suggests a worsening or deteriorating condition, which is not implied by transitory.

4. Someone who is FRUSTRATED/ANNOYED is?

A. Exacerbated
B. Transient
C. Lithe
D. Terse

Correct answer: A

Rationale: The word 'exacerbated' means to make a problem, bad situation, or negative feeling worse. If someone is frustrated or annoyed, they are likely feeling worse due to a particular situation or circumstance. Choice B, 'transient,' means temporary or short-lived, which does not directly relate to the feeling of being frustrated or annoyed. Choice C, 'lithe,' means thin, supple, and graceful, which is not synonymous with being frustrated or annoyed. Choice D, 'terse,' means brief and to the point, which is unrelated to the context of feeling frustrated or annoyed.

5. Which term is descriptive of a small child just learning to walk?

A. Obese
B. Toddler
C. Geriatric
D. Hale

Correct answer: B

Rationale: The correct answer is 'B: Toddler.' A toddler is a young child typically between the ages of one and three who is just learning to walk. 'Obese' (choice A) refers to excess body fat, 'Geriatric' (choice C) pertains to elderly individuals, and 'Hale' (choice D) means strong and healthy, none of which are descriptive of a small child learning to walk.
