100% Correct – Chamberlain
Which antibiotic drug class listed is known for all drugs within the class promoting the
developments of a Clostridioidies difficile infection? - Correct answer Cephalosporin
Bactericidal antibiotics directly kill bacteria - Correct answer preferred for
immunocompromised patients such as those with diabetes, HIV, or cancer and for
those who have overwhelming infections. Agents: aminoglycosides, beta-lactams,
fluoroquinolones, metronidazole, most antimycobacterial agents, streptogramins, and
vancomycin.
IV Meds? - Correct answer Critical or severe infections IV
PO Meds - Correct answer • Mild/moderate or patients admitted for other diagnoses
PO • Switch from IV to PO once the patient is stable
,Bactericidal - Correct answer • Bactericidal antibiotics directly kill bacteria
Bactericidal - Correct answer preferred for immunocompromised patients such as

Agents: aminoglycosides, beta-lactams, fluoroquinolones, metronidazole, most
antimycobacterial agents, streptogramins, and vancomycin.
Bacteriostatic - Correct answer • Bacteriostatic agents inhibit bacterial proliferation
while the host's immune system does the killing.
Bacteriostatic - Correct answer Agents: clindamycin, macrolides, sulfonamides, and
tetracyclines
Broad-spectrum - Correct answer o Targets wider number of bacteria types o Acts on
both gram- and gram + organisms. o Commonly used for empiric therapy when the
pathogen is unknown or infection with multiple types of bacteria is suspected. • Risks
include disruption of normal flora and development of antibiotic resistance.
,• Narrow-spectrum: - Correct answer Effective against a specific bacteria type. o Used
when infecting pathogen is known. o Reduces risk disruption of normal flora and
development of antibiotic resistance. o Preferred when possible.
Blepharitis (with corneal involvement) - Correct answer • Likely caused by
staphylococcus • Therapeutic drug class: Tetracyclines • Likely prescription:
Doxycycline PO x 1 month
Conjunctivitis - Correct answer • Likely caused by staphylococcus, streptococcus •
Therapeutic drug class: Topical broad-spectrum • Likely prescription: Polymyxin-
trimethoprim ophthalmic drops for 7-10 days
Contact-lens conjunctivitis - Correct answer • Likely caused by pseudomonas •
Therapeutic drug class: Topical fluoroquinolone • Likely prescription: Besifloxacin
ophthalmic drops for 7-10 days
, Hordeolum (stye) - Correct answer • Likely caused by S. Aureus, MRSA • Therapeutic
drug class: Topical broad-spectrum • Likely prescription: Bacitracin ointment for 5-7
days
Otitis externa - Correct answer Likely caused by staphylococcus or pseudomonas •
Therapeutic drug class: Fluoroquinolones Likely prescription: Topical ciprofloxacin otic
drops
Acute otitis media - Correct answer • Likely caused by streptococcus pneumonia
Therapeutic drug class: Broad-spectrum penicillin or penicillin/ beta-lactamase Likely
prescription: After observing for 3 days, consider amoxicillin or amoxicillin 10 days.
Bacterial pharyngitis - Correct answer Likely caused by group A streptococcus
Therapeutic drug class: Broad-spectrum penicillins Likely prescription: Amoxicillin PO
x 10 days
