Magazine Chapter 2: Problem 126
. Which of the following antibiotics is indicated for a post-operative surgical wound infection positive for staphylococcus? 1\. Tetracycline (TCN) 2\. Amoxicillin (Amoxil) 3\. Sulfa 4\. Cefoxitin (Mefoxin)
Short Answer
Expert verified
4. Cefoxitin (Mefoxin) is the best choice for staphylococcal wound infections.
Step by step solution
01
Understanding Post-Operative Surgical Wound Infections
Post-operative surgical wound infections are commonly caused by Staphylococcus bacteria. It's important to identify the effective antibiotic to treat such common infections.
02
Evaluating Tetracycline
Tetracycline is a broad-spectrum antibiotic. While it is used for certain infections, it is not the first choice for treating staphylococcal infections in surgical wounds.
03
Evaluating Amoxicillin
Amoxicillin is a penicillin-type antibiotic that can treat bacterial infections. However, it is not specifically indicated for staphylococcal infections due to potential resistance.
04
Evaluating Sulfa Drugs
Sulfa drugs (sulfonamides) are effective against a wide range of bacterial infections. However, they are not the top choice for staphylococcal post-operative wound infections.
05
Evaluating Cefoxitin
Cefoxitin is a second-generation cephalosporin used specifically for treating staphylococcal infections, including those resistant to penicillin. It is often chosen for surgical site infections.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Antibiotics for Staphylococcus
Staphylococcus bacteria, or "staph," are notorious for causing infections, particularly after surgeries. Understanding which antibiotics effectively target these bacteria is critical for successful treatment. Not all antibiotics work equally well against staph infections due to varying resistance levels.
- Tetracycline: This broad-spectrum antibiotic covers many types of bacteria, but it's not the best choice for staph infections, especially in surgical wounds.
- Amoxicillin: While helpful for various infections, staph bacteria have developed resistance to this penicillin-type antibiotic, making it less effective.
- Sulfa Drugs: These medicines are useful against certain bacteria, but they're not the go-to for staph infections related to surgery.
- Cefoxitin: A more targeted choice, particularly effective against staph, including penicillin-resistant strains. Often used in cases of post-operative infections.
Post-Operative Wound Treatment
Post-operative wound treatment is crucial for a patient's recovery and health. After surgery, wounds are susceptible to bacterial infections which can complicate healing. Staphylococcus is a common cause and demands prompt treatment.
Effective treatment involves meticulous care which includes:
Effective treatment involves meticulous care which includes:
- Cleansing the Wound: Regular cleaning with appropriate solutions to prevent infection build-up.
- Monitoring for Signs of Infection: Redness, swelling, or unusual discharge should signal immediate attention.
- Applying the Correct Antibiotics: Choosing the right antibiotic, like cefoxitin, ensures that staph bacteria are eliminated effectively.
- Maintaining Sterility: Using sterile dressings and keeping the wound shielded from contaminants.
Cephalosporin Antibiotics
Cephalosporins, a class of antibiotics, play a pivotal role in fighting bacterial infections, particularly in surgical contexts. They are categorized into different generations, each serving distinct purposes.
- First-Generation: Effective against gram-positive bacteria, often used in uncomplicated skin infections.
- Second-Generation: This is where cefoxitin comes in, effective against penicillin-resistant staph infections and perfect for treating post-operative wound infections.
- Third, Fourth, and Fifth Generations: Offer broader spectrum coverage, especially useful in hospital settings for severe or resistant infections.
Nursing Pharmacology
Nursing pharmacology is a central part of caring for patients, equipping nurses with knowledge to safely administer medications and monitor patient reactions. Proficiency in pharmacology ensures the right drug reaches the patient safely.
Key aspects of nursing pharmacology related to antibiotic treatment include:
Key aspects of nursing pharmacology related to antibiotic treatment include:
- Understanding Drug Mechanisms: How antibiotics work to target specific bacteria, like staphylococcus in post-operative infections.
- Dosage and Administration: Knowing correct dosages to maximize effectiveness while minimizing side effects.
- Monitoring for Adverse Reactions: Observing patients for allergic reactions or other side effects of antibiotics.
- Educating Patients: Teaching patients about their medications ensures compliance and understanding of their treatment plan.
