Question 2

Contact lenses can be manipulated with gloved hands.

Accepted Answer

All laboratories need programs to minimize risks to the health and safety of employees,volunteers,and patients.Suitable physical arrangements,an acceptable work environment,and appropriate equipment need to be available to maintain safe operations.In addition to Standard Precautions,a variety of other safety practices should be adhered to in order to reduce the risk of inadvertent contamination with blood or certain body fluids.These practices include the following:
 1.All devices in contact with blood that are capable of transmitting infection to the donor or recipient must be sterile and nonreusable.
 2.Food and drinks should not be consumed in work areas or stored in the same area as specimens.Containers,refrigerators,or freezers used for specimens should be marked as containing a biohazard.
 3.Specimens needing centrifugation should be capped and placed into a centrifuge with a sealed dome.
 4.Slowly place a gauze square over and carefully open rubber-stoppered test tubes with the gauze over the stopper to minimize aerosol production (the introduction of substances into the air).
 5.Use autodilutors or safety bulbs for pipetting.Pipetting by mouth of any clinical material must be strictly forbidden.

Question 3

Perhaps the simplest and most important step in the proper handling of any hazardous substance is proper:&#10;A) disposal of a chemical.&#10;B) labeling of a substance.&#10;C) storage of a substance.&#10;D) wearing of heavy rubber gloves.

Accepted Answer

Labeling may be the simplest and the single most important step in the proper handling of any hazardous substance.A label for a container should include a date and the contents of the container.When the contents of one container are transferred to another container,this information should also be transferred to the new container.OSHA recommends that all chemically hazardous material be properly labeled with the hazardous contents and severity of the material,as well as bear a hazard symbol.The labels of chemicals in the original containers must not be removed or altered.

Question 4

A carcinogen:&#10;A) is any substance that can cause the development of cancerous growth in living tissue.&#10;B) is related to the spread of viral diseases.&#10;C) cannot be used in the laboratory.&#10;D) is both a and b.

Accepted Answer

Carcinogens are any substances that cause the development of cancerous growths in living tissue; these substances are considered hazardous to people working with them in laboratories.When possible,substances that are potentially carcinogenic have been replaced by ones that are less hazardous.If necessary,with the proper safeguards in place,potentially carcinogenic substances can be used in the laboratory.Lists of potential carcinogens used in a particular laboratory must be available to all who work there.

Question 5

Infectious disease safety practices include:&#10;A) educating and training all health workers in standard precautions.&#10;B) providing disposable gloves.&#10;C) monitoring compliance with protective biosafety policies.&#10;D) all of the above.

Accepted Answer

The purpose of the Bloodborne Pathogens Standard and the Occupational Exposure Standard is to provide a safe work environment.OSHA mandates that an employer do the following:
 1.Educate and train all healthcare workers in standard precautions and in prevention of bloodborne infections.
 2.Provide proper equipment and supplies (e.g.,gloves).
 3.Monitor compliance with the protective biosafety policies.

Question 6

Safety in the clinical laboratory includes:&#10;A) a formal safety program.&#10;B) chemical hygiene plan.&#10;C) bloodborne pathogen plan.&#10;D) all of the above.

Accepted Answer

The Occupational and Safety Health Agency (OSHA)and the Centers for Disease Control and Prevention (CDC)have published numerous safety standards that are applicable to clinical laboratories.Safety in the clinical laboratory includes a formal safety program,specifically mandated plans (e.g.,chemical hygiene and bloodborne pathogens),and identification of various hazards (e.g.,fire,electrical,chemical,and biological hazards).

Question 7

Preemployment health profiles of students and laboratory staff should include immune status evaluation for ____ at a minimum.&#10;A) hepatitis B&#10;B) rubella&#10;C) measles&#10;D) all of the above

Accepted Answer

Preemployment health profiles of students and laboratory staff should include immune status evaluation for hepatitis B,rubella,and measles at a minimum.

Question 8

An important change in the newly revised OSHA Hazard Communication Standard (HCS)is:&#10;A) labels on chemicals must be in different colors.&#10;B) new safety data sheets can be abbreviated documents.&#10;C) a single set of harmonized criteria for classifying chemicals is used.&#10;D) the chemical mixtures must be stated on the container label.

Accepted Answer

The OSHA Hazard Communication Standard (HCS)(29 CFR 1910.1200(g))requires that the chemical manufacturer,distributor,or importer provide safety data sheets (SDSs),formerly material safety data sheets (MSDSs),for each hazardous chemical to downstream users to communicate information on these hazards.
 As with the current standard,the new HCS requires chemical manufacturers and importers to evaluate the chemicals they produce or import and provide hazard information to employers and workers by putting labels on containers and preparing SDSs.The modified standard provides a single set of harmonized criteria for classifying chemicals according to their health and physical hazards and specifies hazard communication elements for labeling and SDSs.Employers must ensure that SDSs are readily accessible to employees.
 The major changes to the HCS include the following:
 1.Hazard classification: Chemical manufacturers and importers are required to determine the hazards of the chemicals they produce or import.Hazard classification under the new,updated standard provides specific criteria to address health and physical hazards as well as classification of chemical mixtures.
 2.Labels: Chemical manufacturers and importers must provide a label that includes a signal word,pictogram,hazard statement,and precautionary statement for each hazard class and category.
 3.Safety data sheets: The new SDS format requires 16 specific sections,ensuring consistency in presentation of important protection information.
 4.Information and training: To facilitate understanding of the new system,the new standard requires that workers be trained by December 1,2013,and beyond for specified requirements.
 The Hazard Communication Standard in 1983 gave the workers the "right to know," but the new Globally Harmonized System gives workers the "right to understand."

Question 9

Information related to hazards associated with chemicals in the workplace must be provided in:&#10;A) Laboratory Policy Manual.&#10;B) material safety data sheets (MSDSs).&#10;C) Bloodborne Pathogen Standards information.&#10;D) Standard Operating Procedures Manual.

Accepted Answer

Hazards associated with chemicals are provided in MSDSs,which describe hazards,safe handling,storage,and disposal of hazardous chemicals.The information is provided by chemical manufacturers and suppliers about each chemical and accompanies the shipment of each chemical.

Question 10
