1. What does the word BILATERAL mean?

A. 2-sided
B. Straight
C. Symmetrical
D. On one side

Correct answer: A

Rationale: The word 'bilateral' means having or relating to two sides. 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.

A. A group of denominations
B. A type of lipoprotein

D. A certain digital value

Correct answer: B

Rationale: The correct answer is B: A type of lipoprotein. LDL stands for Low-density lipoprotein, which is a type of lipoprotein that carries cholesterol through the bloodstream.

Rationale: Correct! Puerilism refers to behaving in a childish or immature manner. In the context of older patients with dementia showing signs of puerilism, it suggests they may exhibit behaviors associated with acting like a child.
