The nursing student learns about anti-infectives in class and demonstrates the need to study more when making what statement about how anti-infectives work?
 
  A) Some anti-infectives interfere with biosynthesis of the pathogen's cell wall.
  B) Some anti-infectives prevent the cells of the organism from using essential substances.
  C) Many anti-infectives interfere with the steps involved in protein synthesis.
  D) Some anti-infectives interfere with ribonucleic acid (RNA) synthesis in the cell leading to cell death.

Question 2

Answer to Question 1

D
Feedback:
Some anti-infectives interfere with deoxyribonucleic acid (DNA) synthesis, not RNA synthesis, in the cell, leading to inability to divide and causing cell death. The fluoroquinolones work in this way. The other three options are correct and would not indicate the need for further study time. Penicillins interfere with biosynthesis of the cell wall, sulfonamides prevent organisms from using substances essential to their growth and development, whereas aminoglycosides, macrolides, and chloramphenicol interfere with protein synthesis.

Answer to Question 2

C
Feedback:
The nurse should question the order initially. The dosage is twice the dose for a 9-year-old is expected to receive. The other options are appropriate and would be done. However, out of safety concerns, the nurse would clarify the dosage first.
