CK-MB Myoglobin Troponin AOTA Correct Answer C. Troponin Rationale: Troponin is elevated up to 10 -14 days after Myocardial Infarction. Specific gravity measured by refractometer: 1.035. Protein and glucose both trace in reagent strip: Presence X -ray medium Albuminuria Glucosuria Normal Correct Answer A. Presence X -Ray medium Rationa le: Xray medium/Radiographic dye can cause erroneo us 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 Correct Answer B. The organism has no cell wall. Feedback Pneumonia caused by Mycoplasma pneumoniae is routinely treated with antibiotics, although the disease is u sually 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).

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 Correct Answ er 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 Correct Answer A. Lysine decarboxylase Feedback: Salmonella (+); Citrobacter ( -) Arrange the common Rh antigens according to immunogenicity (greatest to least): D>c>E>C>e D>C>E>c>e D>c>E>e>C C>D>c>E>e Correct Answer A. D>c>E>C>e Feedback Most immunogenic D > c > E > C > e least immunogenic. Most common error in Polymerase Cha in Reaction (PCR) is NUCLEIC ACID CONTAMINATION. A True (Correct Answer) B False Correct Answer A. True What disease is associated with the possession of HLA -B27? Ankylosing spondylitisThe benefits of buying summaries with Stuvia:
