Infection
An infection is an invasion by pathogens that reproduce, multiply, and cause disease.
- One-celled plants and animals are called:
unicells.
microorganisms.

Microorganisms are tiny, one-celled plants and animals. They are also called microbes.
- Which term describes microbes that produce infection and disease?
Penicillinase
Bactericides
Pathogens
Leukocytes
Pathogens
Microbes that produce infection and disease are called pathogens.
- Which bacteria would cause an infection deep within the body, such as in a joint?
Arthrogenic bacteria
Aerobic bacteria
Anaerobic bacteria
Acidophilic bacteria
Anaerobic bacteria
Anaerobic bacteria can survive without oxygen and can grow deep within the body, such as in a joint.
- Which term means rod-shaped bacteria?
Cocci
Bacilli
Spiral
Vibrios
Bacilli
Bacilli are rod-shaped bacteria.
- Which is the most important defense mechanism of the external immune system?
Mucous membranes
Tears
Stomach secretions
Skin
Skin
The skin is the most important defense mechanism of the external immune system.
- Which cells are part of the internal immune system?
Erythrocytes
Thrombocytes
Leukocytes
Dermatophytes
Leukocytes
Leukocytes are part of the internal immune system. Their function is to fight infection. They are also called white blood cells, and they produce protein antibodies that help destroy microorganisms as they enter the body.
- Which protein is (are) produced when an unfamiliar microorganism enters the body?
Antibodies
Hemoglobin
Myoglobin
Phagocytes
Antibodies
Antibodies are produced when unfamiliar microorganisms enter the body.
- Which term describes a way of stimulating the production of antibodies by exposing the body to weakened or killed germs?
Immunization
Infection
Isolation
Administration
Immunization
Immunization is a way of stimulating production of antibodies by exposing the body to weakened or killed germs.
- The process of placing a small amount of dead or weak disease germs into the body is called:
vaccination.
administration.
injection.
introduction.
vaccination.
Vaccination is the process of introducing an infectious agent to the body to establish resistance to an infection.
- Thin, less elastic skin, decreased secretion of stomach acid, and weakened muscular structures are all risks factors for infection in a(n):
AIDS patient.
pediatric patient.
older adult patient.
postoperative patient.
older adult patient.
Risk factors for infection in the older adult patient include thin, less elastic skin, decreased secretion of stomach acid, and weakened muscular structures.
- Which term means an infection that occurs in a hospital or long-term care facility?
Acquired
Nosocomial
Institutional
Staff
Nosocomial
Nosocomial infection refers to an infection that occurs in a hospital or long-term care facility.
- Handwashing, sterilization of equipment, and the wearing of protective clothing are all examples of:
Bactericidal techniques.
aseptic techniques.
infectant techniques.
immunization techniques.
aseptic techniques.
Handwashing, sterilization of equipment, and the wearing of protective clothing when caring for patients are all aseptic techniques.
- Which term indicates primary strategies that prevent infections transmitted through blood, body fluid, non-intact skin, and mucous membranes?
Isolation precautions
Infection precautions
Standard precautions
Microorganism precautions
Standard precautions
Standards Precautions are primary strategies to prevent infections transmitted through blood, body fluid, non-intact skin, and mucous membranes.
- Which term indicates drugs that kill microorganisms directly?
Bacteriocidal
Anticidal
Microbial
Streptocidal
Bacteriocidal
Bacteriocidal is a term used to describe drugs that kill microorganisms directly
- Which test can identify pathogens to determine the specific antibiotic that should be prescribed?
Wrights stain
Gram stain
Microbial stain
Giemsa stain
Gram stain
A gram stain is used to identify pathogens to determine the specific antibiotic that should be prescribed.
- Which procedure would assist the physician in choosing a drug that is effective against the pathogen?
Culture and sensitivity test
Antibiotic effectiveness test
Antimicrobial awareness test
Resistance and specificity test
Culture and sensitivity test
Culture and sensitivity is a laboratory technique for finding out which, if any, microbes are present, and which antibiotic will be effective against a specific pathogen. Broad -spectrum antibiotics are effective against a wide variety of pathogens.
- Why do physicians prefer to prescribe narrow-spectrum antibiotics?
Broad-spectrum antibiotics give more types of organisms a chance to develop resistance.
Broad-spectrum antibiotics are more expensive than narrow-spectrum antibiotics.
Narrow-spectrum antibiotics are less likely to cause hypersensitivity.
Narrow-spectrum antibiotics are faster acting than broad-spectrum antibiotics.
Broad-spectrum antibiotics give more types of organisms a chance to develop resistance.
Broad-spectrum antibiotics give more types of organisms a chance to develop resistance so physicians prefer to prescribe narrow-spectrum antibiotics.
- Which term indicates an altered state of reactivity in which the body reacts with an exaggerated immune response?
Hyper immunity
Hypersensitivity
Hyperreactivity
Hyper Antibiotics
Hypersensitivity
Hypersensitivity is an altered state of reactivity in which the body reacts with an exaggerated immune response.
- What term indicates a severe, possibly fatal systemic hypersensitivity reaction to a sensitizing agent—that is, a drug, food, or chemical?
Anabolic
Anaphylaxis
Anaerobic
Asepsis
Anaphylaxis
Anaphylaxis is a severe, possibly fatal systemic hypersensitivity reaction to a sensitizing agent such as a drug, food, or chemical.
- Which term describes a secondary infection that occurs while an antibiotic is destroying the first infection?
Hyperinfection
Massive infection
Superinfection
Broad infection
Superinfection
A superinfection is a secondary infection that occurs while the antibiotic is destroying the first infection.
- Which statement describes important information that patients must receive while on antibiotic therapy?
Stop taking the medication as soon as symptoms disappear to avoid a superinfection.
Take all of the medication to ensure that the drug does not fail.
Pathogens are usually destroyed with the first few doses; save extra doses for the future.
As soon as you are fever-free, the medication should be discontinued; the therapy has worked.
Take all of the medication to ensure that the drug does not fail.
Instruct patients to take all of the medication to ensure that the drug does not fail. An antimicrobial drug often fails because the dose is too small or the drug is taken for too brief a time. Never discontinue antimicrobial drugs until the patients have been fever-free and feeling well for 48 to 72 hours.
- Which antibiotic is the most effective and least toxic?
Tetracyclines
Penicillins
Macrolides
Aminoglycosides
Penicillins
Penicillin is the most effective antibiotic and the least toxic.
- Pathogens that secrete a substance called penicillinase:
resist penicillin decoys.
resist penicillin.
destroy penicillin decoys.
destroy penicillin.
resist penicillin.
Penicillinase is an enzyme produced by microbes that makes them resistant to penicillin.
