antibiotics that act against an extensive range of disease-causing bacteria by targeting both gram-positive and gram-negative bacterial groups.

Answer 10

Broad-spectrum antibiotics

Question 11

are animals or persons who show no symptoms f illness but who have pathogens on or in their bodies that can be transferred to others

Answer 11

Carriers

Question 12

when a pathogen is present on or in the body but does not cause harm, the pathogen is _______ the site.

Answer 12

Colonizing

Communicable

Question 14

the elimination of all pathogens except bacterial spores

Answer 14

Disinfection

Question 15

accumulated fluid appears as localized swelling

Answer 15

Edema

Question 16

can occur when some of the patient’s flora become altered and overgrowth results. E.g. streptococci

Answer 16

Endrogenous infection

Question 17

arises from microorganisms external to the individual that do not exist as normal flora. E.g. Salmonella

Answer 17

Exogenous infection

Question 18

Question 20

restricted to a limited area

Answer 20

Localized

Question 21

apply when a healthcare worker is or potentially may be exposed to:
1. Blood,
2. All body fluids, secretions, and excretions except sweat,
3. Nonintact skin, or
4. Mucous membranes. Include the appropriate use of gowns, gloves, masks, eye where, and other protective devices or clothing.

Answer 21

Routine practices

Question 22

bloody drainage

Answer 22

Sanguineous

Question 23

thin, watery drainage that is blood tinged

Question 24

include using an adequate amount of soap, rubbing the hands together to lather the soap and create friction and rinsing under a stream of water

Answer 24

Hand-washing

Question 25

an infection acquired after admission to a health care facility that was not present or incubating at the time of admission

Answer 25

Health care-associated infection (HAI)

Question 26

the body's ability to stay safe by affording protection against harmful agents and involves lines of defense against most microbes as well as specialized and highly specific response to a particular offender

Answer 26

Immune response

Question 27

occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. Damaged cells release chemicals including histamine. These cause blood vessels to leak fluid into tissues, causing swelling.

impaired immune system

Answer 29

thick drainage that contains pus

Answer 34

Purulent
