It is often used to describe something that occurs on both sides, such as bilateral symmetry in which an object is symmetrical on two sides. Choice B, 'Straight,' does not capture the meaning of bilateral. Choice C, 'Symmetrical,' while related, does not specifically convey the idea of something pertaining to two sides. Choice D, 'On one side,' is the opposite of what bilateral means.

4. An enervated patient is ___________.

A. anxious
B. immature
C. tired
D. frightened

Correct answer: C

Rationale: Enervated refers to being weakened or lacking energy, so an enervated patient would likely be fatigued or tired. This term does not specifically imply anxiety, immaturity, or fear, making 'tired' the most suitable choice in this context. 'Anxious' (choice A) means feeling nervous or worried, which is not directly related to being enervated. 'Immature' (choice B) refers to lacking maturity or development, which is unrelated to the patient's energy level. 'Frightened' (choice D) means feeling afraid or scared, which is not necessarily connected to being enervated.
