<span>HIV medications can help lower your viral load, fight infections, and improve your quality of life. But even if you take them, you can still give HIV to others. They're not a cure for HIV.The goals for these medicines are to:<span>Control the growth of the virusImprove how well your immune system worksSlow or stop symptomsCause as few side effects as possible</span>The FDA has approved more than two dozen antiretroviral drugs to treat HIV infection. They're often broken into six groups because they work in different ways. Doctors recommend taking a combination or "cocktail" of at least two of them. This is called antiretroviral therapy, or ART.Your doctor will let you know specifically how you should take your medications. You need to follow the directions exactly, and you shouldn't miss even one dose. Or you could develop drug-resistant strains of HIV, and your medication may stop working.Some other medicines and supplements don't mix well with HIV drugs, so make sure you tell your doctor about everything you're taking.</span><span>Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs)NRTIs force the HIV virus to use faulty versions of building blocks so infected cells can't make more HIV.<span><span>Abacavir, or ABC (Ziagen)</span><span>Didanosine, or ddl (Videx)</span><span>Emtricitabine, or FTC (Emtriva)</span><span>Lamivudine, or 3TC (Epivir)</span><span>Stavudine, or d4T (Zerit)</span><span>Tenofovir, or TDF (Viread)</span><span>Zidovudine, or AZT or ZDV (Retrovir)</span></span></span><span>Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs)These are also called "non-nukes." NNRTIs bind to a specific protein so the HIV virus can't make copies of itself, similar to jamming a zipper.<span><span>Delavirdine (Rescriptor)</span><span>Efavirenz (Sustiva)</span><span>Etravirine (Intelence)</span><span>Nevirapine (Viramune)</span>Rilpivirine (Edurant)</span></span><span>Protease Inhibitors (PIs)These drugs block a protein that infected cells need to put together new copies of the HIV virus.

Answer:
Ions are atoms with a positive or negative charge.
Explanation:
Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.
The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.
The other options are not correct because of:
- <em>There are usually as many or more neutrons than protons.
</em>
- <em>Uncharged atoms are neutral.
</em>
- <em>The number of protons or neutrons does not affect the electric charge of the atom.</em>
- <em>Atoms that joined in fixed proportions can form molecules.</em>
