Results
#1. In the case of a 32-year-old patient with a history of multiple animal bites presenting with a virulent staphylococcal infection in the upper thigh, what is the most appropriate antibiotic? ? Vancomycin is effective against MRSA, which is often associated with animal bite infections.
Vancomycin
Vancomycin is effective against MRSA, which is often associated with animal bite infections.
#2. Which of the following principles for antibiotic therapy in surgical infection is accurate? ? The principles of antibiotic therapy in surgical infection emphasize the use of antibiotics in specific cases.
Only spreading infections or signs of systemic infection justify the use of antibiotics.
The principles of antibiotic therapy in surgical infection emphasize the use of antibiotics in specific cases.
#3. What should be determined whenever possible before initiating antibiotic therapy for surgical infection? ? It is essential to determine the causative organism and its sensitivity to choose the appropriate antibiotic.
Previous antibiotic use
It is essential to determine the causative organism and its sensitivity to choose the appropriate antibiotic.
#4. In surgical cases where anaerobic coverage is needed, which antibiotic is often combined with a broad-spectrum antibiotic like meropenem? ? Metronidazole is effective against anaerobic bacteria and is used for anaerobic coverage in combination therapy.
Metronidazole
#5. Why should serum levels of glycopeptide antibiotics be monitored during treatment? ? They are ototoxic and nephrotoxic, so serum levels should be monitored
To detect ototoxic and nephrotoxic effects
They are ototoxic and nephrotoxic, so serum levels should be
monitored
#6. physician prescribes a one-time high-dose aminoglycoside therapy for a patient. What is the primary reason for this approach? ? Sustained high toxic levels of aminoglycosides can lead to ototoxicity and nephrotoxicity. Using single, large doses can help mitigate these risks.
To reduce the risk of ototoxicity and nephrotoxicity.
Sustained high toxic levels of aminoglycosides can lead to ototoxicity and nephrotoxicity. Using single, large doses can help mitigate these risks.
#7. Which antibiotic may be administered orally, rectally, or intravenously and is useful for prophylaxis and treatment of anaerobic infections after abdominal, colorectal, and pelvic surgery? ? Metronidazole can be administered through various routes and is useful for anaerobic infection prophylaxis and treatment after specific surgeries.
Metronidazole
Metronidazole can be administered through various routes and is useful for anaerobic infection prophylaxis and treatment after specific surgeries.
#8. Which antibiotic class is stable to β-lactamase, has a broad spectrum of anaerobic and gram-positive activity, and is effective for the treatment of resistant organisms like ESBL-resistant urinary tract infections? ? Carbapenems, like meropenem, are stable to β-lactamase and effective against resistant organisms like ESBL-resistant urinary tract infections.
Carbapenems
Carbapenems, like meropenem, are stable to β-lactamase and effective against resistant organisms like ESBL-resistant urinary tract infections.
#9. Infections caused by which bacterium can be treated effectively with ampicillin and amoxicillin? ? Ampicillin and amoxicillin are effective against Enterobacteriaceae
Enterobacteriaceae
Ampicillin and amoxicillin are effective against Enterobacteriaceae
#10. In a complex surgical infection requiring broad-spectrum coverage, which combination is most appropriate when using cephalosporins? ? Cephalosporins can be combined with metronidazole to provide broad-spectrum coverage when anaerobic bacteria are involved in complex surgical infections.
Cephalosporins and metronidazole
Cephalosporins can be combined with metronidazole to provide broad-spectrum coverage when anaerobic bacteria are involved in complex surgical infections.
