A client is admitted to the hospital with elevated temperature, chills, cough, and fatigue. The health care provider orders a ch
est x-ray, which indicates pneumonia. The blood cultures also come back positive for a Gram-negative bacillus. The provider orders two antibiotics to be given to the client, one for Gram-negative organisms and one for Gram-positive organisms. Why does the provider not prescribe just one antibiotic for both types of bacteria?
Broad-spectrum antibiotics can cause antibiotic resistance.
Explanation:
Antibiotics are the substances that inhibit the growth of or kill the bacteria and hence, these are used as medications for the treatment of a lot of bacterial diseases.
These antibiotics can either be of broad-spectrum or the narrow spectrum.
The broad-spectrum antibiotics are the ones that are effective against a variety of bacteria, both gram-positive and negative whereas the narrow-spectrum antibiotics are the ones that target only a specific type of bacteria.
Since the bacteria can mutate very fast and hence, develop antibiotic resistance, the doctors usually avoid prescribing broad-spectrum antibiotics and only use them when the causal bacteria is completely unknown.
Hence, in the given case the provider prescribes separate medications for both types of bacteria.
The answer to this question would be: electron microscope
Cilia is a part of the paramecium membrane that looks like hairy projection. The size of cilia is too small to be examined closely using the light microscope. In this case, the electron microscope can provide a bigger magnification.
