Question 1

When placing an IV catheter in a dog's cephalic vein, which hand position is used to raise the vein?

Accepted Answer

The assistant occludes the vein proximal to the insertion site

Answer

Occluding the cephalic vein proximal (toward the elbow) to the insertion site causes blood to pool distally, making the vein visible and turgid for catheter placement.

Question 2

A veterinary assistant notices a surgical patient's mucous membranes are white and the capillary refill time (CRT) is 3 seconds. These findings suggest:

Accepted Answer

Hypovolemia or poor perfusion

Answer
