Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?
A patient visits her doctor with symptoms typical of a bladder infection. She is immediately prescribed an 800 mgdose of antibiotic (bioavailability = 1/2, t½ = 12 h). The corresponding plasma concentration of drug is found to be 96 micrograms/ml. What is the volume of distribution of this drug? Please round to the nearest liter.
A 10 mg/Kg dose of a drug is given by intravenous injection to a 20 Kg dog. What would the volume of distribution be if the drug had been given orally and only 50% of the drug was absorbed (the concentration of drug at time = 0 is 0.1 mg/L)? Be sure to show your work.
