NR565 FINAL- WEEK 5 EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+ Bacteriostatic - -Bacteriostatic drugs focus largely on killing the bacteria that is causing illness and less on inhibiting the growth of the bacteria. Ex: clindamycin, macrolides, sulfonamides and tetracyclines Bactericidal - -here is just as much emphasis on killing the offending bacteria as there is in stopping the growth or spread of the infection. Patients that have a life-threatening infection or if they are immunoc...
