3.4.1 Use of Antibiotics

• Antibiotics kill or inhibit bacteria, while painkillers relieve symptoms like pain.


  True
• How do antibiotics work at a cellular level?

  Interfere with bacterial processes
• Protein synthesis inhibition is used by tetracyclines and macrolides
• Painkillers target the bacteria directly to eliminate the infection.

  False
• Penicillins work by inhibiting cell wall synthesis
• Antibiotics can target viruses to prevent replication.

  False
• Cell wall synthesis inhibition by penicillin leads to bacterial cell rupture
• Which antibiotic inhibits protein synthesis?

  Tetracyclines
• Rifampicin works by inhibiting RNA synthesis in bacteria.


  True
• Penicillins inhibit cell wall synthesis
• What specific type of synthesis does rifampicin inhibit?

  RNA synthesis
• What is the primary function of antibiotics?

  Treat bacterial infections
• Match the feature with the correct medication:

  Function of antibiotics ↔️ Kill or inhibit bacteria

  Function of painkillers ↔️ Relieve symptoms (e.g., pain)
• Cell wall synthesis inhibition is a mechanism of action used by penicillin.


  True
• Which antibiotics interfere with DNA/RNA synthesis in bacteria?

  Quinolones, Rifampicin
• What is the mechanism of action for cephalosporins?

  Inhibit cell wall synthesis
• Which antibiotics inhibit protein synthesis?

  Tetracyclines, Macrolides
• What is the primary difference between antibiotics and painkillers in treating infections?

  Antibiotics target bacteria
• DNA/RNA synthesis inhibition is a mechanism of action used by quinolones.


  True
• Penicillins inhibit cell wall synthesis
• Match the antibiotic type with its mechanism of action:

  Penicillins ↔️ Inhibit cell wall synthesis

  Tetracyclines ↔️ Inhibit protein synthesis

  Quinolones ↔️ Inhibit DNA/RNA synthesis
• Tetracyclines inhibit protein synthesis.


  True
• Steps to use antibiotics properly:

  1️⃣ Take them only when prescribed

  2️⃣ Complete the full course

  3️⃣ Avoid sharing antibiotics

  4️⃣ Do not use for viral infections
• Completing the full course of antibiotics is essential, even if you feel better.

  True
• Self-medicating with antibiotics can lead to antibiotic resistance.


  True
• What process does penicillin inhibit in bacteria?

  Cell wall synthesis
• Why should antibiotics not be used for viral infections like the flu?

  They are ineffective against viruses
• Completing the full course of antibiotics reduces the risk of antibiotic resistance.


  True
• Avoid sharing antibiotics with others, as each person's infection and medical history are unique.
• Antibiotics should only be taken when prescribed to treat bacterial infections.
• Proper prescription ensures the right antibiotic is used at the correct dosage and duration.


  True
• Antibiotic resistance occurs when bacteria develop the ability to withstand the effects of antibiotics.
• Sharing antibiotics exposes bacteria to drugs they were not prescribed for, increasing the risk of resistance.
• To prevent antibiotic resistance, antibiotics should only be used when prescribed.
• Antibiotics should be taken only when prescribed by a healthcare professional
• Why are antibiotics ineffective against viral infections?

  They target bacteria only
• Antibiotics work by killing or inhibiting the growth of bacteria
• Tetracyclines and macrolides inhibit protein synthesis
• Take antibiotics only when prescribed by a healthcare professional for bacterial infections.
• Antibiotics are effective against viral infections like colds or the flu.
