Question 19

Act against either gram positive or gram negative
- Most efficient

Answer 19

NARROW SPECTRUM

Question 20

• Act against both gram positive and gram negative
• Doctors first use for they don’t know the result, then shifts
  to narrow spectrum
• Trial & error

Answer 20

BROAD SPECTRUM

Question 21
