antibiotics will reduce effects of ...? CORRECT ANSWERS
contraceptives - use protection
antibacterial - penicillin (amoxicillin) CORRECT ANSWERS
weakens and destroys the cell walls of bacteria that are sensitive
antibacterial - cephalosporin (cephalexin) CORRECT ANSWERS
weaken and destroy the cell walls of bacteria that are sensitive
antibacterial – tetracycline CORRECT ANSWERS
inhibit protein synthesis by inhibiting the transfer of RNA from binding with messenger RNA.
amino acids cannot be added to the peptide chain. blocks bacterial protein synthesis, which
prohibits the bacteria from replicating
antibacterial - macrolides (erythromycin) CORRECT ANSWERS
inhibit protein synthesis. Inhibit the transfer RNA from binding with messenger RNA. amino
acids cannot be added to the peptide chain. this then blocks bacterial protein synthesis, and
bacteria cannot replicate
antibacterial - aminoglycosides (gentamicin) CORRECT ANSWERS
third type of antibiotic that inhibits protein synthesis. they also inhibit transfer RNA from
binding with messenger RNA. this synthesizes abnormal proteins due to incorrect reading of the
genetic code. then, a leaky cell wall eventually cause death
antibacterial - fluroquinolones (ciprofloxacin) CORRECT ANSWERS
cause the death of susceptible bacterial cells by inhibiting the two enzymes necessary for the
replication of DNA and cell division, DNA gyrase and topoisomerase IV
antibacterial - sulfonamides (trimethoprim/sulfamethoxazole bactrim) CORRECT ANSWERS
inhibit folic acid synthesis, which is a requirement for the synthesis of DNA, RNA, and cellular
proteins. they do this by blocking one step in the synthesis process
antibacterial - lipoglycoproteins (televancin) CORRECT ANSWERS

2025/2026 BEST GRADED TO SCORE A+ FOR PASS
treat resistant gram+ bacteria (MRSA), hospital acquired bacterial pneumonia, ventilator-
associated bacterial pneumonia, and complicated skin & soft-tissue infections
antibacterial - oxazolidinone (linezolid) CORRECT ANSWERS
effective against MRA, VRE, and pneumonia and skin infections caused by gram+ streptococcus
and staphylococcus bacteria
antibacterial - nitrofurantoin (Macrodantin) CORRECT ANSWERS
treatment and prevention of UTIs
antimycobacterial – Isoniazid CORRECT ANSWERS
treats TB
antimycobacterial – rifampin CORRECT ANSWERS
adjunct therapy for TB. effective against Neisseria meningitidis, legionella, & staphylococcus
antiparasitics - metronidazole (Flagyl) CORRECT ANSWERS
damages the DNA in anaerobic organisms. unique because it does not produce a pharmacologic
action until it is nside the anaerobic organisms. then damages DNA inside it, interfering with its
ability to replicate
antifungal - polyene antibiotics (amphotericin B, nystatin) CORRECT ANSWERS
"poke holes" in fungi by attaching to ergosterol
antifungal - azoles (ketoconazole) CORRECT ANSWERS
treats severe systemic fungal infections & cutaneous fungal infections
antivirals - acyclovir (Zovirax) CORRECT ANSWERS
acts by inhibiting vital replication of DNA. competes with and inactivates viral DNA polymerase
and incorporates itself into the DNA strand. bacteriostatic against both herpes simplex and
herpes zoster
when taking tetracycline what should be avoided? CORRECT ANSWERS
sunlight & tanning beds. wear protective clothing if exposed to the sun
