Answer to Question 1

A
Feedback:
Olanzapine has been associated with weight gain, hyperglycemia, and initiation or aggravation of diabetes mellitus. Other options are not necessary for patients taking olanzapine unless a secondary diagnosis indicates a need.

Answer to Question 2

D
Feedback:
The septum is a partition that separates the right and left halves of the heart. The right half receives deoxygenated blood from everywhere in the body and the left half receives oxygenated blood from the lungs. The auricle is an appendage attached to each atrium, which collects blood that is pumped into the ventricles by atrial contractions. Impulses are sent from the atria into the ventricles by way of the bundle of His, which then enters the septum and subdivides into three bundle branches that become a network of fibers that delivers the electrical impulse to the ventricular cells. The myocardium forms two intertwining networks, atrial and ventricular syncytia, which enable first the atria and then the ventricles to contract synchronously when excited by the same stimulus.
