When disposing of a used needle, you should:
a) destroy the needle and dispose of it in the appropriate container
b) separate the needle and syringe and dispose of it in the appropriate container
c) recap the needle and dispose of it in the appropriate container

d) handle the needle carefully and dispose of it in the appropriate container
Used needles could harbor dangerous bacteria and diseases, so handling the needles as little as possible is advised. Destroying the needle is not correct because when you break it the contents could go into the air you are breathing. Separating the needle is not correct because it would cause you to handle the needle longer than necessary, increasing risk of harming yourself. Recapping is not correct because you could potentially stick yourself with the needle.

This bloating can cause decreased blood flow and the loss of stomach tissue if it is not treated immediately. Many times, the animal needs surgery to relieve the pressure.
Barium is considered a/an:
a) Soluble positive contrast medium
b) Insoluble negative contrast medium
c) Soluble negative contrast medium
d) Insoluble positive contrast medium
d) Insoluble positive contrast medium
Barium can absorb more xrays than bone, so it will appear whiter on radiographs.

d) compress the vein by placing one hand on the medial side of the upper thigh
b) place the fingers of one hand behind the patient’s elbow to extend the front leg
Choice a would be used for extraction from a jugular vein. Choice c would be used for extraction from the lateral saphenous vein. Choice d would be used for an extraction from the femoral vein of a feline patient.
