FAQs

Q: What is selective toxicity? A: Selective toxicity means an antimicrobial harms the microorganism much more than the host. This principle makes safe treatment possible because bacterial cell walls and ribosomes differ from human cells.

Q: What is the difference between bactericidal and bacteriostatic drugs? A: Bactericidal drugs kill bacteria directly, like penicillins and aminoglycosides. Bacteriostatic drugs stop bacteria from multiplying, like macrolides and tetracyclines, so your immune system can clear the infection.

Q: Which drugs belong to the penicillin class? A: Common penicillins include penicillin G, penicillin V, amoxicillin, and ampicillin. They work by blocking bacterial cell wall synthesis and are mainly active against gram-positive bacteria.

Q: Why do aminoglycosides require careful dosing? A: Aminoglycosides such as gentamicin and amikacin can cause kidney damage and hearing loss. Nurses must monitor renal function and drug levels to prevent toxicity.

Q: What are macrolides used for? A: Macrolides like azithromycin and erythromycin treat respiratory tract infections, atypical pneumonia, and some sexually transmitted infections. They are often used in patients allergic to penicillin.

Q: How do cephalosporins differ from penicillins? A: Cephalosporins also target the bacterial cell wall but have a broader spectrum and are grouped into generations. Later generations cover more gram-negative bacteria, while early ones focus on gram-positive infections.

Q: What should I focus on for exams in communicable diseases drugs? A: For BSc Nursing Pharmacology I exams, focus on drug classifications, mechanisms, common side effects, and nursing responsibilities like monitoring for allergic reactions and toxicity. Revise the tables in these notes regularly.

Q: Are these notes enough for my Pharmacology I practical exam? A: Yes, these Communicable Diseases Drugs notes cover the core drug classes and key nursing points. Always cross-check with your university syllabus and clinical guidelines for complete preparation.
