Are tetracyclines bacteriostatic or bacteriocidal? - CORRECT ANSWER: bacteriostatic
Are tetracyclines broad or narrow in spectruM? - CORRECT ANSWER: Broad and they
have a lot of resistance issues
Benzodiazepines affect what neurotransmitter and how? - CORRECT ANSWER:
Increases the effects of GABA
Can valproate (Depakote) be used during pregnancy? - CORRECT ANSWER: It is a

generation? - CORRECT ANSWER: More broad spectrum
Does Lithium have a broad or narrow therapeutic range? - CORRECT ANSWER:
Narrow therapeutic range; toxicity may show nausea and drowsiness
How and when is silver sulfadiazine used? - CORRECT ANSWER: Used for burns, but

How are acyclovir and valcyclovir metabolized? - CORRECT ANSWER: 10% by the

How are sexual side effects linked to SSRIs? - CORRECT ANSWER: Sexual side

medications break the bond that attaches the viral particles to the host cell and keeps
them from replicating
How do anti-virals for HSV and VZV work? - CORRECT ANSWER: They block an
enzyme that is essential in the production of new viruses so they can't replicate
How do SSRIs work? - CORRECT ANSWER: They block the reuptake of serotonin at
the synaptic cleft so there is more serotonin around
How do you discontinue an SSRI? - CORRECT ANSWER: Taper by reducing the dose

during depolarization so it stops the transmission of electrical impulses
How does phentermine work? - CORRECT ANSWER: Treats obesity by decreasing the
hunger perception and releases NE an EPI which breaks down stored fat = lose weight
How does pyrazinamide (PZA) act on bacteria? - CORRECT ANSWER: It is largely
bacteriostatic, but can be bacteriocidal in actively replicating bacteria
How is clarithromycin excreted? - CORRECT ANSWER: It is excreted by BOTH the liver
and the kidneys so dose adjustments are not required in patients with impaired liver
function
How is the gram coverage in Cephalosporins? - CORRECT ANSWER: 1st generation
are gram positive and as you go up in generations, you lose gram positive coverage
and more gram negative
