You have an order for 1 gram of Cefazolin in D5W 100 ml. You have added 5 ml of sterile water to the 1 gram vial to reconstitute powder. However the recommended manufacturer’s diluent amount is 10 ml of sterile water for a final concentration of 100 mg/ml. How would reconstituting the vial with 5 mls affect the concentration and the final calculated dose?
Consider the photos here which demonstrate antibiotic sensitivities of Staphylococcus aureus strains as determined by the Kirby-Bauer method. Abbreviations are as follows: C = chloramphenicol; CC = clindamycin; CZ = cefazolin; E = erythromycin; NOR = norfloxacin; OX = oxacillin; P = penicillin; RA = rifampin; SAM = sulbactam-ampicillin; SXT = sulfatrimethoprim; TE = tetracycline; VA = vancomycin. Imagine that only two cellular changes occurred in the original strain (the first image, on the top) that resulted in the resistance pattern of the strain in the second image (on the bottom). Which combination of mechanisms could explainthese results?Choose one or more: A.expression of efflux pumps B.overproduction of PABA C.production of β-lactamase D.altered penicillin-binding protein E.modification of either 50S or 30S ribosomal subunits F.altered DNA gyrase
A vial of Doxorubicin reads 0•5g per vial. Instructions say to reconstitute each 12mg with 2•5ml of NS. How many ml of NS will be needed to reconstitute the vial of the recommended concentration? please show working
