Question 1

Penicillins

Answer 1

• Benzylpenicillin (Penicillin G) and related drugs
• Antistaphylococcal penicillins
• Aminopenicillins
• Extended spectrum penicillins (Antipseudomonal penicillins)

Question 2

Penicillin (PCN) susceptibility

Answer 2

• Streptococci
• Sensitive enterococci
• Listeria
• Syphilis

Question 3

Semisynthetic penicillins
= penicillinase-resistant penicillins
= lactamase-resistant penicillins
= antistaphylococcal penicillins

Answer 3

• Methicillin
• Oxacillin
• Nafcillin
• Dicloxacillin
• Cloxacillin,
• Flucloxacillin

Question 4

Aminopenicillins

Answer 4

• Ampicillin (IV)
• Amoxicillin (Oral)

Question 5

Aminopenicillins (amoxicillin, ampicillin) susceptibility

Answer 5

Penicillin (but not semisynthetic penicillins) susceptible organisms plus:
- H influenzae
- E coli
- Proteus mirabilis
- Salmonella
- Shigella

Question 6

Anti-pseudomonal penicillins

Answer 6

• Piperacillin
• Ticarcillin

Question 7

Anti-pseudomonal penicillins susceptibility

Answer 7

Ampicillin susceptible organisms plus
- Pseudomonas

Question 8

Beta-lactamase inhibitors

Answer 8

• Tazobactam
• Avibactam
• Clavulanic acid

Question 9

Beta-lactam antibiotics

Answer 9

• Penicillin
