- KCI for injection contains 40 mEq in 20 mL. An order requires 15 mEq, how many mL are needed?A patient has TC levels of 4.8 mmol/L and TG of 1.4 mmol/L, what are his HDL-C and LDL-C levels considering the electrophoretogram values are as follows: LDL-C = 48.8%, VLDL-C = 12.3%, Lp(a)-C = 0.1% and HDL-C = 38.8%? Show full calculation.Calculate the elution volume of blue dextran (blue), myoglobin (red), and Bromocresol purple (purple) in the gel filtration chromatography below with a flow rate of 2.5 mL/min. (Take note that the black colored test tubes represent colorless eluents)
- The accompanying figure is from an electrophoresis experiment using SDS–PAGE. The left lane has the following standards: bovine serum albumin (MW 66,000), ovalbumin (MW45,000), glyceraldehyde 3-phosphate dehydrogenase (MW 36,000),carbonic anhydrase (MW 24,000), and trypsinogen (MW 20,000).The right lane is an unknown. Calculate the MW of the unknown.Assume that Ali (same patient in question 1) was prescribed vancomycin 1000 mg every 36 hours. After few days, Steady-state vancomycin concentrations were obtained before and after the fourth dose, and the peak concentration (obtained ½ hour after a 1- hour infusion of vancomycin) was 34 µg/mL while the trough concentration (obtained immediately before dosage administration) was 2.5 pg/mL. Compute a revised vancomycin dose for this patient to provide a steady-state peak concentration of 48 ug/mL and a steady- state trough concentration of 17 pg/mL. a. Estimate new rate constant (Ke) and half-life (t1/2) b. Estimate volume of distribution (Vd) using this equation Cmaxss + Cminss C. Calculate the new dose interval d.

Calculate the dose for an 8-lb cat. The concentration of gentamicin is 50 mg/ml. Show me your calculation Please note that: 1Kg= 2.2 lbA 158lb adult male diagnosed with endocarditis has an order for gentamicin 3mg/kg/day IV in 2 divided doses, in addition to vancomycin. The Gentamicin is available in 2 mL vials containing 40mg/mL. The facility protocol is to round the gentamicin dose to the nearest 10mg, then calculate the volume of solution to the nearest tenth mL. How many mL will administer per dose?CW is a 74-year-old male patient (65kg) was recently admitted to a hospital due to severe COVID-related pneumonia. He had impaired renal function based on the lab result on the day of his hospital admission, as his serum creatinine (SCr) concentration was 3.6 mg/dL (normal range is 0.74 to 1.35 mg/dL). He was to receive vancomycin for the severe pneumonia. The normal/usual dose of vancomycin is 1 g IV every 12 hours. Using Cockcroft-Gault equation, the elimination rate constant table and the nomogram, calculate the following: a) Adjusted dose of vancomycin based on his creatinine level, while keeping the dosing frequency constant.b) Adjusted dosing interval of vancomycin (tau) based on his creatinine level, while keeping the dose constant.
