Exam 2: NSG 124 / NSG124 (NEW 2024 / 2025 Update) Pharmacology | Review with Questions and Verified Answers | 100% Correct | Graded A - Herzing Q: Penicillins - mechanism of action Answer: - weakens cell wall, causes water uptake and cell rupture - bactericidal (kills cells) Q: Ampicillin Answer: Penicillin preferred drug for gram-negative bacteria Q: patient education for Penicillins Answer: - take with full glass of water - take 1 hour before or 2 hours after meals - most common reaction is an allergic reaction (hives, shortness of breath, wheezing) Q: cephalosporins - mechanism of action Answer: - binds to penicillin-binding proteins, disrupts cell wall synthesis causing cell lysis (breakdown of the outer layer) - bactericidal (kills cells) Q: 1st generation cephalosporins - therapeutic use Answer: - used for simple respiratory, ear, skin, urinary tract infections - not as effective for gram-negative bacteria - do not give to patients with Penicillin allergy Q: 1st generation cephalosporin medications Answer: - cefazolin - cephalexin (Keflex) - cefadroxil Q: 2nd generation cephalosporins - therapeutic use Answer: - more effective for gram-negative bacteria - not effective against meningitis due to poor CSF concentration - do not give to patients with Penicillin allergy Q: 2nd generation cephalosporin medications Answer: - cefaclor (Ceclor) - cefotetan - cefoxitin - cefprozil - cefuroxime Q: 3rd generation cephalosporin medications Answer: - cefdinir - cefditoren - cefixime - cefotaxime - cefpodoxime - ceftazidime - ceftibuten - ceftriaxone Q: 3rd generation cephalosporin - therapeutic use Answer: - preferred therapy due to effectiveness against many bacteria - effective against gram-negative bacteria - good CSF penetration - do not give to patients with Penicillin allergy Q: 4th generation cephalosporins - therapeutic use Answer: - highest effectiveness of gram-negative bacteria - treats severe skin infections, hospital acquired pneumonia - good CSF penetration - do not give to patients with Penicillin allergy Q: 4th generation cephalosporin medications Answer: - cefepime Q: 5th generation cephalosporin - therapeutic use
