- A 500 mL infusion of glucose 5% is being given at a rate of 167 mL/hr. How long will the infusion run at the specified rate?arrow_forwardPredict the effect of 1 L of 600 mOsm/L infusion of sucrose on patients RBC’s osmolality and volume, if previous osmolality of RBC’s was 250 mOsm/L, plasma volume – 3.6 L and RBC’s volume – 2.4 L.arrow_forwardOne model of the glomerular membrane is a microporous membrane in which right cylindrical pores penetrate all the way through the membrane. Assume that the pores have a length of 50 nm and a radius of 3.5 nm. The viscosity of plasma is 0.002 Pa s. The average hydrostatic pressure in the glomerulus is 60 mm Hg, hydrostatic pressure in Bowman's space is 20 mm Hg and the average oncotic pressure of glomerular capillary blood is 28 mm Hg. A. Calculate the flow through a single pore assuming laminar flow (use the Poiseuille flow equation) B. How many pores would there have to be to produce a normal GFR? C. If the total aggregate area of the kidneys for filtration is 1.5 m2, what is the density of the pores (number of pores per unit area)? D. What fraction of the area is present as pores?arrow_forward
- If a patient collects a 24 hour urine specimen with a volume of 1500 mL, and the patient's serum Creatinine is 5 mg/dl, and the urine creatinine is 100 mg/dl, then what is the creatinine clearance in ml/min?arrow_forwardDescribe the pathophysiologic mechanism of syndrome of inappropriate vasopressin secretion, and explain why plasma levels of vasopressin can be normal in these patients.arrow_forwardcalculate the filtered load of a substance that is dissolved in plasma given the plasma concentration of 0.065mg/ml and a GFR of 125 ml/min. consider that 30% of the substance is bound to plasma proteins. Round the answer to one decimal placearrow_forward
- Give typed explanation The provider orders a maintenance dose of Magnesium Sulfate 1(g)/(h) to be given using a premixed bag with a concentration of Magnesium Sulfate 4g in 100mL Normal Saline. You will set the pump for a maintenance dose rate of: m(L)/(h)arrow_forwardWhat concentration of sucrose do you estimate would yield no change inpressure? Why is this biologically significant? Explain in your own words. Do not copy and paste from google. Please refer to your data/graphs on Dialysis tubing cell osmosis.arrow_forwardA 72-year-old adult patient who weighs 78 kg is prescribed by the doctor “Potassium Chloride 40meq in 1L to run for 8 hours” via the peripheral line for a potassium level of 3.3 mEq/L that was drawn this morning. Note: 10 mEq of potassium chloride increases serum potassium levels by approximately 0.1 mEq/.L The concentration of potassium for intravenous administration via a peripheral line should not exceed 40mmol / 500 mL 10 mEq/hr maximum infusion rate; not to exceed 200 mEq dose/24hr Administration rates above 20mmol/hour require cardiac monitoring. How much will the order medication “Potassium Chloride 40meq in 1L to run for 8 hours” raise the patient's potassium level in a day? Is it still within the normal potassium serum levels, which is 3.5–5.0 mEq/L? Does the order comply with the maximum concentration of potassium to be administered peripherally? Does the order’s infusion rate do not exceed the standard maximum infusion rate? Does the order require cardiac monitoring?arrow_forward
- Construct a graph showing difusión time vs column height: don't forget to label axis. Consider how big is my graph.arrow_forwardAn 84 year old male patient has been given a loading dose of digoxin of 298 micrograms in divided doses by intravenous infusion. He has a creatinine clearance (Ccr) of 34 ml / min. What is the maintenance dose (in micrograms) that this patient should receive? Round your answer to the nearest whole number. Use the formula provided to calculate the maintenance dose. Maintenance Dose = Peak body stores x % daily loss 100 Where: Peak Body Stores = Loading Dose % Daily Loss = 14 + Creatinine clearance (Ccr) 5arrow_forwardA normal saline solution (0.9 mg of sodium chloride per 100 ml of solution) is given intravenously and a total of 0.5 L of the solution was given over a 4 hour period. What is the flow rate in units of milliliter per hour?. What is the flow rate in units of mg ( of sodium chloride) per hour?. During 4 hour period how much sodium chloride is delivered?arrow_forward
