Suppose you do this test on a hypothetical Staphylococcus species with the antibiotics penicillin (P-10) and levoflaxacin (L-5). You record identical zone diameters of 25 mm for the levoflaxacin and penicillin disks. Which antibiotic would be more effective against this organism? What does this tell you about comparing zone diameters to each other and the importance of the zone diameter interpretive chart?

The most effective antibiotic would be Levoflaxacin and this would be seen by comparing the diameter zones, which shows why the interpretation of these zones is so beneficial.

We can arrive at this answer because:

In this case, we can state that the analysis and interpretation of the diameter zones are very important to determine the resistance of bacteria to different types of antibiotics.

Levoflaxacin

Explanation:

Levoflaxacin is the antibiotic which is more effective than penicillin against Staphylococcus species because Staphylococcus species are more resistance to penicillin  while not resistance against levoflaxacin antibiotic, so the Levoflaxacin is more effective against Staphylococcus species of bacteria.  Levoflaxacin kills about 99.9% of Staphylococcus species so we can say that it is more effective than penicillin.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
