General purpose utility gloves are

A) For surgeries B) For cleaning procedures C) For handling tubes D) All of the above

Discuss

Answer & Solution

Answer: Option B

Solution:

General purpose utility gloves are used for cleaning procedures such as handling soiled linens or decontaminating care areas. Utility gloves are more tear and puncture resistant than exam or sterile gloves.

70

The theory of relativity is presented by which scientist

A) Albert Einstein B) Isaac Newton C) Stephen Hawking D) Marie Curie

Discuss

Answer & Solution

Answer: Option A

Solution:

Einstein presented his general theory of relativity more than 100 years ago. According to that foundational theory, now known as special relativity, the laws of physics don't care how fast you are going — the laws of physics and the speed of light are the same.
