In preparation for a carotid endarterectomy the surgical technologist should anticipate using which of the following sutures? 

A cardiac arrest occurs during a thoracotomy procedure, and the surgeon calls a CODE BLUE.   The surgeon is attempting to resuscitate the patient using CPR.  Which of the following is the responsibility of the surgical technologist in this situation? 

An OB/GYN surgeon has posted an emergent laparoscopic case and the surgical technologist notices that his reusable metal trocar has not been processed from the day before. Which of the following sterilization methods is the best choice for this scenario? 

Consider the choice structure c=(SB,C) where SB={B(p,w),p in R2++ and w>0} and B(p,w)={x=(x1,x2) in RL+: p.x≤w}; and for each B(p,w) in SB, C(B(p,w))=argmax{x1+x2:x in B(p,w)} (note R2++is  the part of the Euclidean space of dimension two in which each component is positive). Then, (Rc,>c) satisfies WARP.

Let X=R (the set of real numbers) and B={(0,a):a>0}. For which of the following correspondences, (B,C), is a well-defined choice structure?

Suppose that X={x,y,z,w} and B={{x,y,z},{x,y,w},{x,z,w},{y,z,w}}. Consider the choice correspondence C({x,y,z})={x,y}, C({x,y,w})={x,y}, C({x,z,w})={z}, and C({y,z,w})={z,y}. Are these choices strongly rationalized by a preference relation?

A researcher performs a choice experiment on an individual. The researcher offers the agent ten finite menus of alternatives taken from a set X. Each menu is offered only once. From each menu the agent is asked to choose a single alternative. Let (Rc, Tc) be the following binary relations: x Rc y if and only if there is a menu M that is offered to the agent and x is chosen in that menu while y is also available; x Tcy if and only if there is a menu M that is offered to the agent and x is chosen in that menu while y is also available, and y is not chosen in M. Suppose that the agent’s choices are generated as follows. The agent has a utility function on X and chooses uniformly at random among the alternatives that maximize utility. Is (Rc, Tc) necessarily acyclic?

Let SB={{a,b},{a,c},{b,c},{c,d},{d,a}} and for each B in SB, let C(B)={x in B: x is different from a}. From the following, what is the smallest binary relation that weakly rationalizes choice structure c=(SB,C)?
