Which of the following is a common mechanism of action for antibiotics?

  1. Inhibiting cell wall synthesis

  2. Interfering with protein synthesis

  3. Damaging the cell membrane

  4. Blocking DNA replication


Correct Option: A
Explanation:

Many antibiotics work by interfering with the synthesis of the bacterial cell wall, which is essential for the survival of the bacteria.

What is the primary mechanism of action of beta-lactam antibiotics?

  1. Inhibiting DNA gyrase

  2. Interfering with protein synthesis

  3. Damaging the cell membrane

  4. Blocking cell wall synthesis


Correct Option: D
Explanation:

Beta-lactam antibiotics, such as penicillin and cephalosporins, work by inhibiting the synthesis of the bacterial cell wall, leading to cell death.

Which of the following is a common mechanism of action for antiviral drugs?

  1. Inhibiting viral replication

  2. Interfering with viral entry

  3. Damaging the viral genome

  4. Blocking viral attachment


Correct Option: A
Explanation:

Many antiviral drugs work by inhibiting the replication of the virus, preventing the production of new viral particles.

What is the primary mechanism of action of nucleoside reverse transcriptase inhibitors (NRTIs) in the treatment of HIV?

  1. Inhibiting viral replication

  2. Interfering with viral entry

  3. Damaging the viral genome

  4. Blocking viral attachment


Correct Option: A
Explanation:

NRTIs work by inhibiting the reverse transcriptase enzyme, which is essential for the replication of HIV.

Which of the following is a common mechanism of action for antifungal drugs?

  1. Inhibiting cell wall synthesis

  2. Interfering with protein synthesis

  3. Damaging the cell membrane

  4. Blocking DNA replication


Correct Option: C
Explanation:

Many antifungal drugs work by damaging the cell membrane of the fungus, leading to cell death.

What is the primary mechanism of action of azole antifungals?

  1. Inhibiting cell wall synthesis

  2. Interfering with protein synthesis

  3. Damaging the cell membrane

  4. Blocking DNA replication


Correct Option: A
Explanation:

Azole antifungals, such as fluconazole and itraconazole, work by inhibiting the synthesis of ergosterol, a component of the fungal cell wall.

Which of the following is a common mechanism of action for antiparasitic drugs?

  1. Inhibiting parasite metabolism

  2. Interfering with parasite reproduction

  3. Damaging the parasite cell membrane

  4. Blocking parasite attachment


Correct Option: A
Explanation:

Many antiparasitic drugs work by inhibiting the metabolism of the parasite, preventing its growth and reproduction.

What is the primary mechanism of action of artemisinin-based combination therapies (ACTs) in the treatment of malaria?

  1. Inhibiting parasite metabolism

  2. Interfering with parasite reproduction

  3. Damaging the parasite cell membrane

  4. Blocking parasite attachment


Correct Option: C
Explanation:

ACTs work by damaging the cell membrane of the malaria parasite, leading to cell death.

Which of the following is a common mechanism of action for cancer chemotherapy drugs?

  1. Inhibiting cell division

  2. Interfering with DNA replication

  3. Damaging the cell membrane

  4. Blocking cell attachment


Correct Option: A
Explanation:

Many cancer chemotherapy drugs work by inhibiting cell division, preventing the growth and spread of cancer cells.

What is the primary mechanism of action of taxanes, a class of cancer chemotherapy drugs?

  1. Inhibiting cell division

  2. Interfering with DNA replication

  3. Damaging the cell membrane

  4. Blocking cell attachment


Correct Option: A
Explanation:

Taxanes, such as paclitaxel and docetaxel, work by inhibiting cell division by interfering with the formation of microtubules, which are essential for cell division.

Which of the following is a common mechanism of action for immunosuppressive drugs?

  1. Inhibiting T cell activation

  2. Interfering with cytokine production

  3. Damaging the cell membrane

  4. Blocking cell attachment


Correct Option: A
Explanation:

Many immunosuppressive drugs work by inhibiting the activation of T cells, which play a key role in the immune response.

What is the primary mechanism of action of calcineurin inhibitors, a class of immunosuppressive drugs?

  1. Inhibiting T cell activation

  2. Interfering with cytokine production

  3. Damaging the cell membrane

  4. Blocking cell attachment


Correct Option: A
Explanation:

Calcineurin inhibitors, such as cyclosporine and tacrolimus, work by inhibiting the activation of T cells by blocking the calcineurin signaling pathway.

Which of the following is a common mechanism of action for anti-inflammatory drugs?

  1. Inhibiting prostaglandin synthesis

  2. Interfering with cytokine production

  3. Damaging the cell membrane

  4. Blocking cell attachment


Correct Option: A
Explanation:

Many anti-inflammatory drugs work by inhibiting the synthesis of prostaglandins, which are involved in inflammation and pain.

What is the primary mechanism of action of nonsteroidal anti-inflammatory drugs (NSAIDs)?

  1. Inhibiting prostaglandin synthesis

  2. Interfering with cytokine production

  3. Damaging the cell membrane

  4. Blocking cell attachment


Correct Option: A
Explanation:

NSAIDs, such as ibuprofen and naproxen, work by inhibiting the enzyme cyclooxygenase (COX), which is involved in the synthesis of prostaglandins.

Which of the following is a common mechanism of action for antihypertensive drugs?

  1. Relaxing blood vessels

  2. Reducing heart rate

  3. Decreasing blood volume

  4. Blocking nerve impulses


Correct Option: A
Explanation:

Many antihypertensive drugs work by relaxing blood vessels, reducing peripheral resistance and lowering blood pressure.
