Our task is to measure the volume of blood in an elephant. One way to do this would be to drain its blood into a suitable container. Aside from harmful side effects which this method has on the elephant, it will not be successful, as blood will still remain behind in the tissues. Hence, we will inject 2.00 ml of a 2.00 M solution of a dye which the elephant will not appreciably metabolize or excrete in one hour and then measure the concentration of this dye in the bloodstream (our sample being taken from another leg than the point of injection) after 30 minutes, a sufficient time to thoroughly mix the dye in the bloodstream. The concentration of dye at this point is 1.25 x 10-5 M. What is the volume of blood in the elephant?

An OTR is running a group for TBI patients on an inpatient rehabilitation unit. One week into the group (after 5 sessions) the therapist notes that one of the clients has trouble initiating conversation with group members that he has spoken to freely during previous sessions. The therapist suspects that the client is having trouble remembering the names and faces of other group members and doesn’t realize that he already knows them. What standardized assessment could the therapist give to help answer this question?

Among the following reactions, find those that are redox reactions: 1) MnO4- (aq) + 5 Fe2+ (aq) + 8 H+ → 5 Fe3+ (aq) + Mn2+ (aq) + 4 H2O(l) 2) 6 HF + Al(OH)3 + 3 NaOH → Na3AlF6 + 6 H2O 3) Au(s) + 4 H+ + NO3- + 4 Cl- → [AuCl4]- + 2 H2O + NO(g) 4) FeS + 2 HCl → FeCl2 + H2S 5) SiO2 + 4HF → SiF4 + H2O

The OTR administers the contextual memory test. The client is unable to spontaneously identify the theme of the first set of cards and cannot remember about half the items. When the client is provided with the theme at the beginning of the second card set, their performance improves substantially. Which treatment is most appropriate for this client?
