Detailed Answers
Cocci Right Ans - bacteria that are round or spherical in shape
Bacilli Right Ans - rod-shaped bacteria
Protozoa Right Ans - one-celled animals found in decayed materials and
contaminated water
Microorganism Right Ans - any small living organism not visible to the
naked eye
Rickettsiae Right Ans - parasitic microoganisms found on fleas, lice ticks,
and mites
Pathogen Right Ans - any microorganism that causes infection and disease;
a germ
Viruses Right Ans - smallest microorganisms that cannot reproduce unless
they are inside another living cell; cause diseases such as the common cold,
measles, mumps, and hepatitis
Aerobic Right Ans - microorganisms that require oxygen
Asepsis Right Ans - absence of disease-producing microorganisms
Disinfection Right Ans - process that destroys pathogenic organisms but is
not always effective against spores and viruses
Spirilla Right Ans - bacteria that cause diseases such as syphilis and cholera
True Right Ans - many microorganisms are part of the normal flora of the
body and are beneficial in maintaining certain body processes
False Right Ans - a chain of cocci bacteria are staphylococci
, False Right Ans - flagella are thick-walled capsules formed around some
bacteria
false Right Ans - protozoa cause diseases such as ringworm and athletes
foot
true Right Ans - viruses are difficult to kill because they are resistant to
many disinfectants and are usually no affected by antibiotics
false Right Ans - AIDS is caused by the HBV virus
false Right Ans - most microorganisms prefer a cool, dark, and moist

vaccine at no cost to any employee with occupational exposure to blood or
other body secretions
true Right Ans - pathogens are everywhere, and preventing their
transmission is a continuous process
true Right Ans - any object or area that may contain pathogens is
considered to be contaminated
false Right Ans - healthcare facilities use infection-control programs to
prevent and deal with endogenous infections
true Right Ans - common fomites include bedpans, urinals, linens,
instruments, and specimen containers
true Right Ans - body defenses against disease include mucous membranes,
cilia, coughing and sneezing, hydrochloric acid in the stomach, tears in the eye,
and leukocytes
true Right Ans - common aseptic techniques include hand washing, good
personal hygiene, and proper cleaning of instruments and equipment
false Right Ans - sterilization is a process that destroys all microorganisms
but is not always effective against spores and viruses
