The superior mesenteric artery supplies blood to the small intestine, ascending colon, and the left kidney.

What is the difference between an A/V fistula and a A/V graft?

The right and left subclavian veins meet at the superior venacava which in turn leads to the right atrium.

Anticoagulation drugs like Heparin are given after the procedure is complete to help stop bleeding.

Declotting an A/V graft can include which of the following steps?

The pulmonary arteries can only be accessed through the venous system.

The weak acid, hydrocyanic acid (HCN) is dissolved in water to make a 0.15 M solution. Hydrocyanic acid has a Ka = 4 x 10-10. Answer the below questions about this solution when it has reached equilibrium.  PART A: Which of the below options correctly represents the acid dissociation constant expression for the dissociation/ionization reaction of HCN in water? Type your letter answer in the box below in all lowercase. If more than one option applies, type all letters that are correct with no spaces between them. For example: cde   PART B: Calculate the concentrations of all reactants and products at equilibrium. Round your answers to one decimal place AND use the below format for any scientific notation values where the first blank box is for the number and the second box is for the exponent. Example: for 1.5 X 10-4 the 1.5 would go in the first blank box below and the -4 exponent would go in the second blank box below with no spaces.   HCN                  =   CN-                    = X 10^ H3O+                 = X 10^   PART C: What is the pH of this solution. Round your answer to 1 decimal place pH =     PART D: What is the pOH of this solution. Round your answer to 1 decimal place. pOH =     PART E: What is the hydroxide (OH-) concentration of this solution? Round your answer to no decimal places AND use the below format for any scientific notation values where the first blank box is for the number and the second box is for the exponent. Example: for 1 X 10-4 the 1 would go in the first blank box below and the -4 exponent would go in the second blank box below with no spaces. OH-          = X 10^     PART F: Is this solution acidic or basic? Type in all lowercase either acidic or basic below  

Given the below Ka or Kb values (and that Kw = (Ka)( Kb)), calculate the pKa values for each of the below. Round answers to 1 decimal place. a) Carbonic acid     Ka = 4.5 x 10-7    pKa =   b) Benzoic acid      Ka = 6.4 x 10-5    pKa =   c) Hydrazinic acid  Ka = 9 x 10-5       pKa =   d) Lactic acid          Kb = 3 x 10-4      pKa =     Which of the above acids would be the weakest acid? Type a lowercase letter (a, b, c, d, or e) in the box below. Which of the above acids is considered a strong acid that fully dissociates/ionizes? Type a lowercase letter (a, b, c, d, or e or the word none) in the box below.  

Which of the following is true about the below process/reaction? Select all that apply.

SHORT ANSWER. You only need to answer 2 of them. Create and answer your own test question! 😀 Make a question about test material that wasn’t on the exam and answer your own question! It can be ANY type of question: true/false, multiple choice, short answer, matching, etc.
