Question 1

All of the following are considered a hazardous waste EXCEPT ________.&#10;A) broken glass&#10;B) urine&#10;C) a salt solution&#10;D) a preserved specimen

Accepted Answer

A salt solution is not considered hazardous waste unless it contains other hazardous materials. Broken glass can cause injury and is considered sharps waste, urine and preserved specimens may contain infectious materials and are considered biohazardous waste.

Question 2

All of the following are considered to be a hazardous waste EXCEPT ________.&#10;A) blood&#10;B) urine&#10;C) a preserved specimen&#10;D) a salt solution

Accepted Answer

A salt solution is not considered hazardous waste, while blood, urine, and preserved specimens can all contain hazardous materials and therefore require proper disposal.

Question 3

All of the following are proper guidelines for using a microscope EXCEPT which statement?&#10;A) Use one hand to carry the microscope.&#10;B) Use only cleaning solution provided by your laboratory instructor to clean the microscope lenses.&#10;C) Use only special lens paper to clean the lenses of the microscope.&#10;D) Unplug the microscope by pulling on the plug, not by tugging on the electrical cord.

Accepted Answer

Using one hand to carry the microscope is not a proper guideline. The microscope should be carried with two hands, one on the arm and one on the base, to prevent it from falling and breaking.

Question 4

Which of the following is a common piece of equipment used in dissecting preserved specimens?&#10;A) microscope&#10;B) microcentrifuge&#10;C) water bath&#10;D) scalpel

Accepted Answer

A scalpel is a common tool used in dissecting preserved specimens. Microscopes, microcentrifuges, and water baths are not typically used in dissection.

Question 5

The following guidelines should be followed when working with body fluids EXCEPT which statement?&#10;A) Always assume that a body fluid can infect you with a disease.&#10;B) Always wear gloves and safety glasses when working with body fluids.&#10;C) Clean up all body-fluid spills with soap and water.&#10;D) Work only with your own body fluids.

Accepted Answer

The answer of The following guidelines should be followed when...

Question 6

Which of the following require wearing gloves to protect your skin?&#10;A) water bath&#10;B) microscope&#10;C) chemicals&#10;D) none of the above

Accepted Answer

Chemicals can be harmful to skin, so gloves should be worn to protect the skin from any contact with chemicals. Water bath and microscope do not necessarily require the use of gloves.

Question 7

All of the following are necessary guidelines to ensure that the laboratory is a safe environment EXCEPT which statement?&#10;A) No eating is allowed in the laboratory, however drinks are allowed.&#10;B) Never perform an experiment without your instructor's permission.&#10;C) Wear shoes at all times in the laboratory.&#10;D) Only students enrolled in the course are allowed in the laboratory.

Accepted Answer

Eating and drinking should not be allowed in the laboratory as it can lead to contamination of experiments and cause potential hazards.

Question 8

The following guidelines will protect you from chemical hazards EXCEPT which statement?&#10;A) Most chemicals are safe to handle with bare hands.&#10;B) When mixing solutions always add a chemical to water; never add water to the chemical.&#10;C) Always use a spoon or spatula to take a dry chemical from a large storage container.&#10;D) Do not return unused portions of chemicals to their original container.

Accepted Answer

The statement "Most chemicals are safe to handle with bare hands" is incorrect and does not provide protection from chemical hazards. It is important to wear appropriate personal protective equipment (PPE) when handling chemicals to minimize exposure and potential harm.

Question 9

The main instrument that you will use to study anatomy is a ________.&#10;A) water bath&#10;B) scalpel&#10;C) microscope&#10;D) microcentrifuge

Accepted Answer

The answer of The main instrument that you will use...

Question 10

Which of the following can be disposed of in the sink?&#10;A) saliva&#10;B) blood&#10;C) salt solution&#10;D) preservative

Accepted Answer

Salt solution (assuming it is not a hazardous chemical) can typically be safely disposed of down the sink as it is a dilute solution that will not harm plumbing or the environment. Saliva should be disposed of in a biohazard container, blood should be disposed of in a regulated medical waste container, and preservatives may contain hazardous chemicals that should not be dumped down the sink.
