Describe in detail the mechanism by which atropine caused this new problem in this angina patient.  Be sure to connect the pharmacodynamics of atropine to the physiology and pathophysiologic mechanisms directly responsible for the new problem.  (You know, the way you did for exam three).  

Imagine you are on your way to administer an IV dose of furosemide (Lasix) to an adult patient with acute pulmonary edema named Morton D. that you haven’t met before.    You must be sure you give Morton the appropriate dose.  You know that furosemide will be almost immediately effective.  You know other stuff about furosemide too.  Regardless, name the first thing you must check about Morton and/or his record before administering the dose as written by the medical student?  (Remember, you’ve been told the patient has acute HF and so is in mortal danger; don’t take too long…)

The titration of 25.0 mL of an unknown concentration H2SO4 solution requires 83.6 mL of 0.12 M LiOH solution. What is the concentration of the H2SO4 solution (in M)?

What mass (in g) of AgCl is formed from the reaction of 75.0 mL of a 0.078 M AgC2H3O2 solution with 55.0 mL of 0.109 M MgCl2 solution? 2 AgC2H3O2(aq) + MgCl2(aq) → 2 AgCl(s) + Mg(C2H3O2)2(aq)

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of K2S and Fe(NO3)2 are mixed.

According to the following reaction, what amount of Al2S3 remains when 20.00 g of Al2S3 and 2.00 g of H2O are reacted? A few of the molar masses are as follows: Al2S3 = 150.17 g/mol, H2O = 18.02 g/mol. Al2S3(s) + 6 H2O(l) → 2 Al(OH)3(s) + 3 H2S(g)

How many grams of Li3N can be formed from 1.75 moles of Li? Assume an excess of nitrogen. 6 Li(s) + N2(g) → 2 Li3N(s)

How many moles of oxygen are formed when 58.6 g of KNO3 decomposes according to the following reaction? The molar mass of KNO3 is 101.11 g/mol. 4 KNO3(s) → 2 K2O(s) + 2 N2(g) + 5 O2(g)

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of K2CO3 and HBr are mixed.

What is the limiting reactant when 24.72 grams of copper (I) bromide is allowed to react with 26.40 grams of lead (II) oxide?  Assume that the reaction procedes according to the UNBALANCED reaction shown below. CuBr + PbO –> Cu2O + PbBr2
