The best and most accurate technique to identify the appropriate vein site for iv catheter insertion into the arm is to apply a tourniquet approximately 4 to 6 inches above in the arm where the catheter is to be inserted.
Applying the tourniquet causes the vein to swell from inside due to the pressure which makes the intended insertion point much more clear and visible and helps the nurse to determine if the vein is capable of accommodating the iv catheter.
Industrial revolution is when people started making a bunch of factories.
It affected the color of dark colored moths because they were able to camouflage into their environment better because of the soot from the factories, therefore increasing the number of dark moths that survived in their environment over light colored moths.
Natural selection is when the environment and environmental factors affect an organisms ability to survive and reproduce in that environment, causing only the most fit organisms to be able to survive and reproduce.

Answer:
D. Fibrocartilage
Explanation:
In order to understand the question, we need to review the structure of intervertebral discs.
Intervertebral discs consist of two parts:
It forms the central part of the intervertebral disc and consists of mucoid substance.
It is composed of encircling layers of fibrocartilage and fibrous tissue surrounding the nucleus pulposus
<u>SLIPPED DISC:</u>
It is characterized by the protrusion of nucleus pulposus through the annulus fibrosus accompanied by the compression of spinal nerves.
Patient may present with loss of sensory sensations or pain or both.
<u>CORRECT ANSWER:</u>
From the above review, the correct answer is <u>D. fibrocartilage</u> as it forms the annulus fibrosus.
