Answer: A. Zidovudine (Retrovir) and emtricitabine (Emtriva)
Explanation:
Basic postexposure prophylaxis (PEP) therapy typically includes treatment with one of these combinations of pharmacologic agents:
Zidovudine (Retrovir) and emtricitabine Emtriva),
Lamivudine (Epivir) and tenofovir (Viread), or
Tenofovir (Viread) and emtricitabine (Emtriva)
If the accidental exposure is especially severe, a third agent may be included.
The possible reason for this condition is Staphylococcus
aureus. Staphylococcus aureus causes over 50% of bone infections. Other
organisms include Proteus vulgaris and Pseudomonas aeruginosa, as well as E.
coli. The Treatment of acute osteomyelitis
includes large doses of I.V. antibiotics (after blood cultures identify the
infecting organism). Surgical drainage may be indicated, and the affected bone
is immobilized. The client usually requires I.V. fluids to maintain hydration,
but oral intake isn't necessarily prohibited.
The abiotic and biotic factors of an ecosystem both interact with each other on many levels. For example, temperature, which is an abiotic factor in most ecosystems, will determine what type of flora and fauna can live there.
Probably. Ecosystems are connected. While scientists do break the world
down to study it in smaller pieces because we can't comprehend the
ecosystem of the whole world at one time, the whole world is one big
ecosystem. Some parts of it are more directly connected to others, and
some parts are less directly connected. If something catastrophic
happened in one ecosystem, it would affect other ecosystems. But also
remember that the bigger the network, the less any one species affects
it. Because<span> there
are so many species in the world, the world is a HUGE ecosystem. The
affect would be somewhat absorbed by the vastness of the ecosystem.
However, if the extinction of one species (such as fish) has a large
impact on one ecosystem, it's impact on surrounding ecosystems might be
noticed. When you look at the world as a whole, it's not the extinction
of any one species that is very, very dangerous but the extinction of
many species. If enough species (like the fish) died in "separate"
ecosystems, eventually the ecosystem of the whole would be affected.</span>
