1. R. G. is a 49-year-old male who is a long term smoker and has a strong family history of cardiovascular disease. R. G. was playing golf with friend when he started complaining of chest pain radiating to his left arm and lower jaw. His friend, concerned that R. G. was having a heart attack, rushed him to the hospital. R. G. collapsed while being transported in his friend’s vehicle. Upon arrival at the hospital, R. G. was unconscious and unresponsive to painful stimuli. His skin was cool, clammy, and pale. His blood pressure was inaudible, so the nurse palpated his systolic pressure as 60. He had a weak thready pulse of 90 and respirations were 12. Oxygen was administered by mask at 10 L/min. ECG showed sinus rhythm with frequent premature ventricular complexes. R. G. was given an intravenous bolus of lidocaine and a dopamine drip. Five minutes later, R. G.’s systolic blood pressure was audible at 80 and diastolic pressure was 40. His cardiac rhythm was sinus without ventricular ectopy. ECG showed evidence of an acute injury of the anterior myocardium. 1. What was the purpose of the dopamine in treating R.G’s symptoms?

(A) A (2, 4)-tree. (B) An AVL tree. (C) A hash table where collisions are resolved using linear probing. (D) A B-tree of order log n. (E) None of the above. 3. Consider the following algorithm: Algorithm B(G, u) Input: Undirected, connected graph G, and vertex u of G. Mark(u) c ? 0 For each edge (u, v) incident on u do if (u, v) is not labelled then if v is not marked then { Label (u, v) as discovery c ? 1 + c + B(G, v) } else { Label (u, v) as back c ? c + 1 } return c What value does the above algorithm return?
