A nurse is caring for a client who has a viral infection. Which of the following antiviral groups inhibits viral DNA polymerase or reverse transcriptase enzymes that are essential for viral DNA or RNA synthesis?
This is because nucleoside analogs inhibit viral DNA polymerase or reverse transcriptase enzymes that are essential for viral DNA or RNA synthesis.
Choice B is wrong because Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are wrong because they do not inhibit viral DNA polymerase, but rather bind directly to reverse transcriptase and block its activity.
Choice C is wrong because Nucleotide reverse transcriptase inhibitors (NRTIs) are wrong because they are not nucleosides, but nucleotides that need to be phosphorylated before they can inhibit reverse transcriptase.
Choice D is wrong because Protease inhibitors (PIs) are wrong because they do not inhibit viral DNA polymerase or reverse transcriptase, but rather block the protease enzyme that cleaves viral proteins into functional units.
This is because nucleoside analogs inhibit viral DNA polymerase or reverse transcriptase enzymes that are essential for viral DNA or RNA synthesis.
Some possible explanations for the other choices are:
Choice B is wrong because Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are wrong because they do not inhibit viral DNA polymerase, but rather bind directly to reverse transcriptase and block its activity.
Choice C is wrong because Nucleotide reverse transcriptase inhibitors (NRTIs) are wrong because they are not nucleosides, but nucleotides that need to be phosphorylated before they can inhibit reverse transcriptase.
Choice D is wrong because Protease inhibitors (PIs) are wrong because they do not inhibit viral DNA polymerase or reverse transcriptase, but rather block the protease enzyme that cleaves viral proteins into functional units.
