What is the significance of collecting a culture and sensitivity (C&S) sample before administering the first dose of antibiotics?
- To prevent allergic reactions from occurring
- To determine the most appropriate antibiotic for destroying the bacteria (correct)
- To reduce the risk of superinfection during treatment
- To assess the intensity of allergic reactions
When can allergic reactions occur in relation to antibiotic therapy?
When can allergic reactions occur in relation to antibiotic therapy?
- Only if the antibiotic course is not completed
- Immediately after every dose of antibiotic
- Within days or weeks following the initiation of therapy (correct)
- During the collection of a culture and sensitivity sample
Which infections are considered as superinfections during antibiotic treatment?
Which infections are considered as superinfections during antibiotic treatment?
- Fresh complicating infections like C-diff and fungal infections (correct)
- Bacterial infections causing abscesses
- Chronic infections that pre-existed before antibiotic therapy
- Viral infections such as influenza

Study Notes
Antibiotics Basics
- Sample collection for culture and sensitivity involves obtaining a specimen from the infected body part, such as blood, urine, or skin, and sending it to the laboratory.
- The growth of microorganisms in the lab determines the most effective antibiotic to destroy the bacteria.
- It is essential to collect culture and sensitivity (C&S) samples before administering the first dose of antibiotics.
Allergic Reactions
- Reactions to antibiotics can occur rapidly or may be delayed, taking days or weeks to manifest after therapy initiation.
- Allergic reactions vary in severity, ranging from mild skin rashes to life-threatening anaphylaxis.
- Patients should be assessed for allergic reactions with every dose of antibiotics.
Superinfection
- Superinfections are new, complicating infections that arise during antibiotic therapy.
- Examples of superinfections include:
- C-difficile (C-diff)
- Pseudomembranous colitis (diarrhea)
- Fungal infections (candidiasis)
- Patients should complete the full course of antibiotic medication to minimize the risk of superinfection.
