bile is sterile.

A

False.
Outside of the standard precautions, bile is not sterile.

30
Q

_______ the slice, the ______ it is.

To examine the joint spaces
Ruler is for synovial diarthrodial joints
upper: shoulder, wrist, elbow
Lower: Hips, Knee, ankle

32
Q

For examining the kidney, we want _____ slices.
We want it to be ______.
Why?

A

Thinner slices
Blurry (for the bones)
We want to see the kidney and thin slices make the bones blurrier

33
Q

What is the desired outcome for tomography?

A

Blurriness
