- Why is Muller Hinton Agar (MHA) ideal for antibiotic susceptibility testingDuring a phenotypic method of identifying an unknown microbe, the specimen was noted to be positive for fluorescence. This would indicate that the specimen was: Positive for binding with the special fluorescent antibody solution O Contaminated and must be re-sampled and retested Negative for binding with the special fluorescent antibody solution Radioactive and must be contained immediatelyBlood agar is a differential medium that will show us a clear zone around a colony of normal flora if the organism is capable of gamma-hemolysis. Yes No
- The Centers for Medicare and Medicaid Services (CMS) have initiated revised policies regarding reimbursement to hospitals for care of patients who suffer health care-associated infections (HAIs) such as SSIs. Hospitals must bear the costs of treatment. Health care workers are the key in preventing patient injury and protecting hospitals. What is an example of a routine procedure performed by surgical technologists prior to entering the sterile field that would be part of the aseptic technique?Why is it important to limit the quantity of cells used to prepare a smear? Mark all that apply: 1. So that cells are not clumped and don't entrap stain creating erroneous results 2. So that the cells are spread out enough that cell morphology can be discerned 3. So that there are small groups of cells clumped together to make them visible 4. So that no contaminants are introduced onto the slide by being entrapped in clumps 5. So that the cells are spread out enough that the arrangement can be observedA positive ELISA assay usually results in __________. decreased motility fluorescence agglutination a color change visible bubbling
