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.

ad-work [718]

True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.

A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.

The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is  MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.
