The nurse should obtain the specimen from the catheter.
One of the tests from urinalysis that frequently got contaminated is about infection. The area near the orificium of uretra is near the skin, so there will be microbes around it that can contaminate the sample. The contaminated sample will give a false positive and the result will show the urine are infected.
Taking the specimen from catheter will prevent that contamination, thus giving a better sample.

Explanation: Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
They bring the nutrients toward the shore and increasing the abundance of the organisms.
<u>Explanation:</u>
The deep water brought out to the surface of the land is often rich in the nutrients, coastal up-welling supports the growth of the seaweed and the plankton.
