Which of the following enzymes has the longest elevation after Myocardial Infarction (MI)? CK-MB Myoglobin Troponin AOTA C. Troponin Troponin is elevated up to 10-14 days after Myocardial Infarction. Lactic acid specimen: Chilled and separated from cells Heated Room temperature Request EDTA sample only A. Chilled and separated from cells Feedback Special Handling: No tourniquet. Place on ice immediately and deliver to lab or aliquot within 15 minutes. DO NOT FREEZE WHOLE BLOOD SPECIMEN. Specific gravity measured by refractometer: 1.035. Protein and glucose both trace in reagent strip: Presence X-ray medium Albuminuria Glucosuria Normal A. Presence X-Ray medium Feedback Xray medium/Radiographic dye can cause erroneous results in urine specific gravity measurement. A patient with walking pneumonia is being treated with penicillin. State one possible condition why the patient is not recovering: The organism produces beta lactamase The organism has no cell wall The organism has capsule The organism produces an enzyme that neutralizes the antibiotic B. The organism has no cell wall. Feedback Pneumonia caused by Mycoplasma pneumoniae is routinely treated with antibiotics, although the disease is usually self-limiting. The disease is treated with macrolide, tetracycline, or fluoroquinolone classes of antibiotics. All mycoplasmas lack a cell wall and, therefore, all are inherently resistant to beta-lactam antibiotics (e.g., penicillin). What is the coefficient of variation if the mean is 90 and the standard deviation is 5.48? 2.75 6.09 5.68 30 B. 6.09 Feedback: CV= SD/meanX100, (5.48/90)X100= 6.09. Blood smear below denotes Hairy Cell Leukemia (HCL), which of the following test is used to identify this type of leukemia? Image. 1 Myeloperoxidase Tartrate-resistant acid phosphatase Tartrate-resistant alkaline phosphatase Sudan Black B. Tartrate-resistant acid phosphatase Feedback: Hairy cells demonstrate strong positivity for tartrate-resistant acid phosphatase (TRAP) staining. The hairy cells are larger than normal and positive for CD19, CD20, CD22, CD11c, CD25, CD103, and FMC7. Use to differentiate Salmonella from Citrobacter: Lysine decarboxylase ONPG Indole Vogues Proskauerterm-9 A. Lysine decarboxylase Feedback: Salmonella (+); Citrobacter (-) Arrange the common Rh antigens according to immunogenicity (greatest to least): DcECe DCEce DcEeC CDcEe A. DcECe Feedback Most immunogenic D c E C e least immunogenic.
