- A 56-year-old man comes to the clinic complaining of persistent fatigue for the past three months. The physician decides to order multiple blood tests including an erythrocyte sedimentation rate and C-reactive protein. Which of the following best describes the clinical conclusion that should be reached if this patient's erythrocyte sedimentation rate is 22 mm/h and his C-reactive protein is 3.5 mg/dL? (A) Indicates the definitive presence of a rheumatoid disorder (B) Indicates the likely presence of infection or inflammation (C) Indicates the presence of a severe bacterial infection (D) Indicates the presence of cancer involving the bone marrow (E) Indicates the presence of rouleaux and the blood's ability to coagulateA hospital pharmacy has available 2-mL prefilled syringes containing 80 mg of tobramycin and 1.5-mL prefilled syringes containing 60 mg of tobramycin. The syringes are calibrated in 0.25-mL units. Explain how you would prepare a medication order calling for 110 mg of tobramycin to be added to 100 mL of D5W for intravenous infusion.The simple form of |Hoff equation is: II = [B]RT In this equation the [B] is the molar concentration of solute. So: n m [B] = v MV = cg /MA Where c, the mass concentration of the solute is in the total volume of solution and M, is the molar mass of the solute. This equation can be replaced in the previous one to get: RT II = MA In this equation molar mass of given solute can be detemined from the slope of the II vs Cz plot. This equation applies only to solutions that are sufficiently dilute to behave as ideal-dilute solutions. In the case of non-ideal solutions, however, the extended formula is: II = [B]RT{1+ k. [B] + n. [B]² + ...} Biological macromolecules dissolve to produce solutions that are far from ideal, but we can still calculate the osmotic pressure by assuming that the van't Hoff equation is only the first term of a lengthier expression: II [B]RT(1+ b. [B]) II = RT + bRT. [B] [B] II = RT + bRT./M. */Ma п RT ÞRT Ca MA MA In this equation molar mass of given biomolecule can…
