notka56 [123]

The nurse should respond to the client's question based on fact that gram-negative bacteria are increasingly resistant to each succeeding generation.

<h3>What is cellulitis?</h3>
  • A typical skin illness caused by bacteria that can be dangerous.
  • The bacteria invade the skin in cellulitis.
  • Cellulitis may disseminate quickly. Skin damage causes it to appear bloated, red, and maybe hot and sensitive.
  • Cellulitis can be fatal if not treated with an antibiotic.
<h3>How cephalosporin acts against gram-negative bacteria ?</h3>
  • The antibacterial characteristics of cephalosporins are used to classify them into generations.

  • The concept of generations linked to pharmaceuticals is not adequately described by any of the remaining possibilities.
