Morphine is injected intravenously into a patient’s blood stream in a solution of 2 mg/mL at a rate of 1 mL/hour. The patient is bleeding at a constant rate of 3 mL/hour. The patient normally has 5 L blood in their body, and will lose consciousness if they lose more than 40% of their total blood volume. What is the concentration of morphine in their blood (mg/L) by the time they lose consciousness, assuming they have excellent circulation?

Are these pharmacology questions correct?
16 The volume of distribution of a drug in the body is always equal to which of the following? The total volume of the body The volume of extracellular fluid in the body The volume of water in the body The total volume of the body minus the blood volume None of the above (a) (b) (c) (d) (e) volume of distribution are reported to be 3 hours and 0.25 L/kg respectively.

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...

Calculate the hardness of water in units of mg/L of Caco3 (see equation 15-7) if your titration at pH 10 resulted in a concentration of 15 mmol/L. Round your answer to the nearest whole number and enter only the numerical answer into the box. In most natural waters, some magnesium ion is present, so expressing water hardness in units of mg/L of CaCO3 is an arbitrary convention that has been adopted for the sake of convenience (or tradition). The conversion...

7. Smokers are known to have about 50% higher CL than nonsmokers for theophylline. If the average observed AUC after administration of 300 mg IV theophylline in nonsmokers is 100 mg.hr/L, what is the expected AUC in smokers after administration of the same 300 mg dose? Theophylline undergoes linear pharmacokinetics 2. After administration of a single 400 mg dose of a drug, a linear plot of the serum concentration-time prorile on a semi-log graph paper showed a y-intercept of 1mg/mL...

1. Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x-37.5 m1kg . Assume that ơ-7.70 ml/kg for the distribution of blood plasma. a. Find a 99% confidence interval for the population mean blood...

1. An effluent water contains significant quantities of non-emulsified oil with a concentration of 176 mg/l. In order to maintain the concentration of the oil below 25 mg/l, alum with a dosage of 35mg/l was used. Based on the preliminary experiments it was found that every gram of alum produces 0.65 g of sludge. The weight percentage of sludge in the effluent is 2.75. The flow rate of oily effluent water to the treatment unit is 0.75 m3/min at 30°C....
