Cards

Term
Narrow Spectrum vs. Broad Spectrum
Definition
Broad-- kills good and bad organisms.
Narrow-- kills specific organism
Term
Superinfections, like C diff, are more likely in which spectrum of drugs?
Definition
Broad-- due to the organism being unknown, Empiric therapy can cause good and bad organisms to be killed leaving opportunity for other infections to occur.
Term
What should be assessed before administering and antibiotic?
Definition
ALLERGIES
RENAL CLEARENCE
BASELINE WBC
SITE OF INFECTION
Term
Nursing Care for Antibiotics
Definition
Instruct pt/family to take all medications as prescribed, Immediately report signs of allergic reaction and about contraception.
Monitor WBC and differential count.
--working if WBC goes down and temperature.
Term
Antibiotics and Pregnancy?
Definition
Penicillins and tetracyclines reduce contraception effectiveness.
Term
Whats the most sever side effect of Antibiotics?
Definition
anaphylaxis
TREATMENT: Epinephrine
Term
Why assess renal clearance?
Definition
drugs are eliminated by the kidney;
can lead to Nephrotoxicity
Term
What is prophylactic therapy?
Definition
Giving antibiotics before surgery to prevent infection.
[give one hour before, stop within 24 hours post-op unless theres and infection]
Term
What are the BETA-LACTAM antibiotics?

Term
Beta Lactam Mechanism of Action
Definition
Irreversible inhibitors of transpeptidase-- inhibit cell wall synthesis
Term
Anything that interrupts cell wall
Definition
CIDAL

Allergy potentional between pencillin and cephalosporins
Definition
Cephalosporins has fewer allergic reactions than PCN
--10% chance of severe reaction if severely allergic to PCN
Term

What are Beta Lactamase Inhibitor PCNs
Definition
resistant micrograms
Term
Beta Lactamase Inhibitor PCNs Mechanim of action and usage
Definition
(combination PCNs) widely used in hospitals and outpatient settings to keep resistance down while penicillin does its job.
Term
Nephrotoxicity and PCNs
Definition
as age goes up, creatine goes down; most drugs are excreted renally so a dose reduction may be needed.
Term
How many generations of cephalosporins are there?
Definition
4
Term
Most effective generation
Definition
4th generation due to excellent CSF and gram coverage.
Term
Thrombophlebitis with cephalosporins
-PATIENT TEACHING
Definition
Give slow IV piggyback
dilute drug
monitor IV site closely.
Term

Definition
broad spectrum bacteriacidal drug that interrupts DNA synthesis
Term
What is the most used antibiotics in hospital settings?
Definition
Cephalosporins
Term
Proactive care with Quinolones (5)
Definition
Monitor renal status!

-Protect against sunlight
-May cause confusion in the elderly
-Call provider at first signs of tendon pain or inflammation
-Monitor blood sugar
Term

Term
Quinolones Uses
Definition
GU
Lung and upper respiratory
Bone
Skin
Anthrax
Term
Macrolides Mechanism of Action
Definition
Inhibit protein synthesis
Low vs High Dose determines CIDAL OR STATIC
Term
Oldest Macrolide
Definition
Erythromycin
Term
Macrolides Uses
Definition
-AIDS-related infections
-Legionnairs Disease (drug of choice)
-Chlamydia and Mycolplasma Pneumonia
-If allergic to PCN
Term
Erythromycin IV and thrombophlebitis
Definition
Monitor IV site for vein inflammation
Term
Erthromycin increases the levels of what 2 drugs due to its potent effect as a CYP450 inhibitior?
Definition
(anti-epileptic drug)carbamazepine and warfarin (anti-coagulant)
Term
Proactivity of Macrolides
Definition
Erythromycin
--Assess for GI effects
--Drug interactions
--Monitor LFTS (can be hepatotoxic)

Zithromax
--give on empty stomach
--Explain long action of drug to patients due to long half.
Term
Clindamycin mechanism of action
Definition
inhibits protein synthesis
Term
What kind of coverage does a Clindamycin antibiotic have?
Definition
Great anaerobic coverage
Term
What is a major concern for Clindamycin (e.g. what is it known to cause?)
Definition
AAPC--Antibiotic Associated Pseudomembranous Colitis, condition of the colon associated with Clostridium difficile
Term
Proactivity with Clindamycin
Definition
Monitor bowel movements
--blood and mucus
--abdominal pain
Monitor for dehydration
Dont andmister antidiarrheals!
Prevent AAPC
Term
What is Vancomycins Uses and Coverage?
Definition
MRSA infections
PCN allergic patients for Streptococcal endocarditis.
Topically in bowel for AAPC

Narrow coverage-- only works on gram positive. (Staphylococcus and Streptococcus)
Term
