Antibacterials Flashcards
Inhibits bacterial growth
Bacteriostatic
Bacteria killing
Bactericidal
A disease-producing microorganism
Pathogen
Substances that inhibit bacterial growth or kill bacteria and other microorganisms
Antimicrobials
Resistance caused by prior exposure to an antibacterial
Acquired resistance
Microscopic organisms that include viruses, fungi, protozoa, and rickettsiae
Microorganisms
Antibody proteins such as IgG and IgM
Immunoglobulins
Bacterial resistance that results naturally
Inherent resistance
Crystals in the urine
Crystalluria
Infections acquired while patients are in the hospital
Health-care acquired infection (nosocomial infection)
Antibiotics that are effective against one type of organism
Narrow-spectrum antibiotics
A new infection in a patient with preexisting infection
Superinfection
Kidney toxicity
Nephrotoxicity
Ear poisoning that results from exposure to drugs or chemicals that damage the inner ear or the vestibulocochlear nerve
Ototoxicity
A skin reaction caused by exposure to sunlight
Photosensitivity
Amount of antibacterial drug needed to stop growth of a microorganism
Minimum Effective Concentration (MEC)
Factors that influence the body’s ability to fight infection include:
Age, nutrition, antibodies, circulation, WBCs, and organ function.
What type of test should be ordered before antibiotics are administered?
Culture & Sensitivity
List contributions to antibiotic resistance.
Taking antibiotics for viral infections. Taking antibiotics incorrectly (skipping doses).
Resistance that can occur between antibacterial drugs that have similar actions.
Cross resistance
True or False: Broad-spectrum antibacterial drugs can be used to treat infections before culture and sensitivity results are received.
True
