    • C.

      Any antibiotic that is the most expensive is the best to give

    • D.

      Use of a bacteriostatic rather than a bactericidal

    Correct Answer
    A. Use of a bactericidal rather than a bacteriostatic
    Explanation
    The principle of using antibiotics is to use a bactericidal (kills bacteria) rather than a bacteriostatic (inhibits bacterial growth) antibiotic.

    What is the mycotic aneurysm?

    • A.

      Complication of arterial wall from hematogenous spread of bacterial infection

    • B.

      Complication by antibiotic prophylaxis

    • C.

      Infection to the mediastinum and spread the infection to the brain.

    Correct Answer
    A. Complication of arterial wall from hematogenous spread of bacterial infection
    Explanation
    A mycotic aneurysm refers to a complication of the arterial wall that occurs due to the hematogenous spread of a bacterial infection. This means that bacteria from another part of the body enter the bloodstream and travel to the arterial wall, causing an infection. This infection weakens the arterial wall, leading to the formation of an aneurysm. It is important to note that mycotic aneurysms are different from true aneurysms, which are typically caused by weakening of the arterial wall due to factors such as high blood pressure or atherosclerosis.

      Antibiotic resistant

    • D.

      Antibiotic sensitivity

    Correct Answer
    A. Antibiotics kill bacteria
    Explanation
    The correct answer is "antibiotics kill bacteria." Bactericidal antibiotics are a type of antibiotic that directly kill bacteria by disrupting their cell walls or interfering with essential cellular processes. This is in contrast to bacteriostatic antibiotics, which only inhibit the growth and reproduction of bacteria without directly killing them. Bactericidal antibiotics are often used in cases of severe infections or when the immune system is compromised, as they provide a more immediate and effective means of eliminating bacterial pathogens.

    What is the Bacteriostatic antibiotic?

    • A.

      Antibiotic limit growth of bacteria

    • B.

      Antibiotics kill bacteria

    • C.

      Antibiotic resistant

    • D.

      Antibiotic sensitivity

    Correct Answer
    A. Antibiotic limit growth of bacteria
    Explanation
    Bacteriostatic antibiotics are a type of antibiotic that inhibit the growth and reproduction of bacteria, but do not directly kill them. These antibiotics work by interfering with essential bacterial processes, such as protein synthesis or DNA replication, which slows down or stops bacterial growth. This allows the body's immune system to effectively eliminate the bacteria. Bacteriostatic antibiotics are often used when the immune system is capable of fighting off the infection with some assistance, or when it is important to prevent the development of antibiotic resistance.

      Lowest Concentration of antimicrobial drug which prevents visible growth of bacteria

    • B.

      Lowest Concentration of bacteria in blood

    • C.

      Lowest concentration of bacteria in the infection side

    Correct Answer
    A. Lowest Concentration of antimicrobial drug which prevents visible growth of bacteria
    Explanation
    The minimum inhibitory concentration (MIC) refers to the lowest concentration of an antimicrobial drug that is needed to prevent the visible growth of bacteria. This means that at concentrations below the MIC, the drug is not effective in inhibiting bacterial growth, while at or above the MIC, the drug is able to prevent the growth of bacteria. The MIC is an important measure used in determining the effectiveness of antimicrobial drugs and helps in determining the appropriate dosage for treatment.

    • A.

      Anaerobic

    • B.

      Aerobic

    • C.

      Mix

    Correct Answer
    A. Anaerobic
    Explanation
    Acute orofacial infections are typically caused by multiple types of microorganisms, with anaerobic bacteria being the dominant species. Anaerobic bacteria are able to thrive in low oxygen environments, such as the oral cavity, and are commonly associated with dental infections, abscesses, and periodontal diseases. These bacteria can cause significant tissue damage and inflammation due to their ability to produce toxins and enzymes. In contrast, aerobic bacteria require oxygen to survive and are less commonly associated with these types of infections. The presence of anaerobic bacteria in acute orofacial infections highlights their importance in the pathogenesis and treatment of these conditions.

    Bactericidal and bacteriostatic drugs given together are?

    • A.

      Antagonistic

    • B.

      Independently active

    • C.

      Additive

    • D.

      Synergistic

    Correct Answer
    A. Antagonistic
    Explanation
    When bactericidal and bacteriostatic drugs are given together, they have opposite effects on the growth and survival of bacteria. Bactericidal drugs kill bacteria, while bacteriostatic drugs inhibit their growth. When used together, the bacteriostatic drug may interfere with the bactericidal drug's ability to kill bacteria, reducing its effectiveness. This results in an antagonistic effect, where the drugs work against each other and diminish the overall antimicrobial activity.
