ANTIBIOTIC DRUGS Flashcards
This is a also known as prokaryotes which are single-celled organisms that lack a true nucleus and nuclear membrane
BACTERIA
Drugs do not act alone in destroying bacteria. Together with natural body defenses, surgical procedures and dressing changes are needed to eliminate infecting bacteria
ANTIBACTERIAL DRUGS
Equal to the sum of the effects of two antibiotics
ADDITIVE EFFFECT
Occurs when one antibiotic increases the effectiveness of the 2nd drug
POTENTIATIVE EFFECT
When two drugs are used together, the desired effect may be greatly reduced
ANTAGONISTIC EFFECT
When a drug selected is known to be the best drug that can kill the MO
EMPIRIC THERAPY
Once the MO is identified in the lab, the antibiotic therapy is tailored by using the most narrow-spectrum, least toxic drug based on C&S results
DEFINITIVE THERAPY
When signs and symptoms do not improve
SUBTHERAPEUTIC
Occurs when the antibiotics reduce or completely eliminate the normal bacterial flora
SUPERINFECTION
WHAT ARE THE PREVENTING NURSING MEASURES
1.Perform hand hygiene before and after client contact
2.Recognize invasive procedures that increase the chance of infection
3.Encourage health measures by maintaining up-to-date immunization status
4.Use infection control procedures to prevent transmission
5.Evaluate effectiveness of treatment
THE ANTIBIOTICS AFFECTING THE BACTERIAL CELL WALL
1.Penicillin
2.Cephalosporins
3.Other Inhibitors
THE ANTIBIOTICS AFFECTING PROTEIN SYNTHESIS
1.Tetracyclines
2.Macrolides
3.Aminoglycosides
Use cautiously in clients who have or are at risk for kidney dysfunction
Penicillins
what antibiotic is not given to children below 8 years old, pregnant and lactating mothers d/t significant tooth discoloration of the child?
