a) A patient is found to have a urine flow rate of 1 ml/min, a plasma urea concentration of 20 mg/100 ml, and a urinary urea concentration of 1000 mg/100 ml. Calculate the specific plasma clearance of urea for this individual. b)What is the relative plasma clearance of urea for the patient in “A” if GFR = 75 ml/min? Does the patient reabsorb or secrete urea? How can you tell?

2. Renal Function and Dialysis Metabolism of protein in your diet produces urea as a byproduct. The rate of urea production (r_u) depends on how much protein you eat and how big you are (measured by your body fluid volume, V). A realistic urea production rate for an average person (\/=40 L) is about r_u= 15 mg/min. Urea produced in the liver is rapidly distributed throughout the body's fluid volume V; the average urea concentration in the body's fluids is...

You have an order to start an infusion of Amiodarone at 1 mg/min for the first six hours. You have 500 mL of D5W with 900 mg of Amiodarone. What is your rate per hour on your IV pump? The physician's order reads to start an epinephrine drip at 0.15mcg/kg/min. Your patient weighs 330 pounds. You have a 50cc bag with 6 mg of epinephrine. What is your rate per hour? You are to start a Heparin drip at 500units/hour....

The resistance to blood flow through an organ is 0.1 mmHg/ml/min. The blood flow rate is 1 L/min. What is the mean arterial pressure, assuming that central venous pressure is 52 2. The diagram represents a segment of a vascular bed. What the total resistance through this segment? PO 100 RA= 5 mmHg/ml/sec Rg = 10 mmHg/ml/sec Rc = 20 mmHg/ml/sec

If 500-mL of an intravenous solution contains 0.3 g of a drug, at what flow rate, in milliliters per minute, should the solution be administered to provide 0.5 mg/min of drug? 500-mL of an intravenous solution contain 0.6% of drug in sodium chloride injection. At what flow rate, in milliliters/minute, should the infusion be administered to provide 150 mg of drug per hour? (10710) A patient is to receive an infusion of a drug at the rate of 54 mg/h...

2. the iv is infusing cia gravity flow. calculate the rate in
mcgtt/min.
the book says the answer is 90 mcgtt/min but how do you get
that?
7. how many mL of iv fluid is the patient receiving in 24
hours? the book says the ans is 2,160 ml. the body weight is 140lb
which is 64kg. what would be the next step?

The human heart delivers a blood flow of about 5000ml/min. The diameter of the blood vessel leaving the heart is 1.8cm. Determine the Re of the flow in this vessel. Is the flow laminar or turbulent? Explain. The smallest blood vessels have a diameter of 10mm and a total area about 1000 times greater than the area of the vessel leaving the heart. Determine the Re in a typical capillary. By what factor does the diameter of a capillary have...
