About This Quiz


An antibiotic is a type of antimicrobial material that is active against bacteria. It is an essential type of antimicrobial agent for fighting bacterial infections, and antibiotic medications are often used to treat and prevent such bacterial infections. They may kill or prohibit the growth of bacteria. If you want to know more about antibiotics, challenge yourself with this quiz.

    Which of the following may cause Steven-Johnson syndrome (loss of skin)?

    • Ciprofloxacin

    • Ampicillin

    • Sulfamethoxazole

    • Tetracycline

    • Cycloserine

    Correct Answer
    A. Sulfamethoxazole
    Explanation
    Sulfamethoxazole is a sulfa drug that belongs to a class of antibiotics known to cause Steven-Johnson syndrome (SJS). SJS is a severe skin reaction that can cause the skin to peel off, leading to a loss of skin. This adverse reaction is more common in individuals who have a genetic predisposition to SJS or who have previously experienced SJS with the use of sulfa drugs. Ciprofloxacin, ampicillin, tetracycline, and cycloserine are not typically associated with causing SJS.

    Which of the following is NOT a cell wall inhibitor?

    • Bacitracin

    • Clindamycin

    • Penicillin V

    • Vancomycin

    • Cefoperazone

    Correct Answer
    A. Clindamycin
    Explanation
    Clindamycin is not a cell wall inhibitor because it works by inhibiting protein synthesis in bacteria, specifically by binding to the 50S subunit of the bacterial ribosome. Cell wall inhibitors, such as Bacitracin, Penicillin V, and Vancomycin, target the synthesis or stability of the bacterial cell wall, which is essential for bacterial growth and survival. Cefoperazone is a third-generation cephalosporin antibiotic that inhibits cell wall synthesis by binding to penicillin-binding proteins. Therefore, Clindamycin is the correct answer as it does not directly target the bacterial cell wall.

    Which of the following antibiotics as a triad of adverse effects?

    • Aminoglycosides and Tetracyclines

    • Penicillin V and Erythromycin

    • Vancomycin and Aztreonam

    • Azetreonam and Erythromycin

    • Aminoglycosides and Vancomycin

    Correct Answer
    A. Aminoglycosides and Vancomycin
    Explanation
    Aminoglycosides and Vancomycin are both antibiotics that can cause a triad of adverse effects. The triad includes nephrotoxicity (toxicity to the kidneys), ototoxicity (toxicity to the ears), and neurotoxicity (toxicity to the nervous system). These adverse effects can be serious and potentially life-threatening. It is important to monitor patients closely when using these antibiotics and adjust the dosage if necessary to minimize the risk of these adverse effects.

    Which of the following may cause seizures?

    • Erythromycin

    • Ofloxacin

    • Trimethoprim

    • Cefepime

    • Ampicillin

    Correct Answer
    A. Ofloxacin
    Explanation
    Ofloxacin is a fluoroquinolone antibiotic that has been reported to have potential side effects of causing seizures. Seizures are a known adverse reaction associated with the use of fluoroquinolones, including ofloxacin. Therefore, it is possible that ofloxacin may cause seizures in some individuals.

    Which of the following is used in orthopedic infections?

    • Niafcillin

    • Moxifloxacin

    • Chloramphenical

    • Erythromycin

    • Clindamycin

    Correct Answer
    A. Clindamycin
    Explanation
    Clindamycin is commonly used in orthopedic infections due to its effectiveness against a wide range of bacteria, including those commonly found in such infections. It is particularly effective against anaerobic bacteria, which are often involved in orthopedic infections. Additionally, Clindamycin has good bone penetration, making it an ideal choice for treating infections in bone and joint tissues.

    Rate this question:

  • 7. 

    Which of the following is not metabolized by the liver?

    • Nafcillin

    • Clindamycin

    • Neomycin

    • Chloramphenicol

    • Tetracylcine

    Correct Answer
    A. Neomycin
    Explanation
    Neomycin is not metabolized by the liver. The liver plays a crucial role in metabolizing drugs and other substances in the body. However, neomycin is primarily eliminated unchanged through the kidneys, rather than being metabolized by the liver. This makes neomycin different from the other options listed, as they are metabolized by the liver.

    Rate this question:

  • 8. 

    Which of the following is only effective when oxygen is present?

    • Aminoglycosides

    • Metronidazole

    • Bacitracin

    • 3rd Generation Cephalosporins

    • Antipsedomonal Penicillin

    Correct Answer
    A. Aminoglycosides
    Explanation
    Aminoglycosides are only effective when oxygen is present because they require an aerobic environment to exert their antimicrobial activity. These drugs work by inhibiting bacterial protein synthesis, and this process is dependent on the presence of oxygen. In anaerobic conditions, such as in abscesses or deep tissue infections, aminoglycosides may not be as effective due to the lack of oxygen. Therefore, they are primarily used to treat infections caused by aerobic gram-negative bacteria.

    Rate this question:

  • 9. 

    Which of the following drugs may present a rash, but is not a hypersensitive reaction if it occurs in children or patients with EBV?

    • Ampicillin

    • Amoxicillin

    • Penicillin G

    • Tetracyline

    • Impenem;Cilastatin

    Correct Answer
    A. Amoxicillin
    Explanation
    Amoxicillin may present a rash in children or patients with EBV, but it is not considered a hypersensitive reaction. This means that the rash is not an allergic reaction to the medication.

    Rate this question:

  • 10. 

    Which two of the following can be used to treat MRSA?

    • Penicillin

    • Ofloxacin

    • Azithromycin

    • Oxacillin

    • Cefepime

    Correct Answer(s)
    A. Ofloxacin
    A. Oxacillin
    Explanation
    Ofloxacin and Oxacillin can be used to treat MRSA. Ofloxacin is a fluoroquinolone antibiotic that is effective against many types of bacteria, including MRSA. Oxacillin is a penicillinase-resistant penicillin that is also effective against MRSA. Penicillin, Azithromycin, and Cefepime are not typically used to treat MRSA infections.
