Which of the following is false about bacterial resistance to antibiotics?

a) pharmaceutical companies generally do not allocate a lot of money to research for new antibiotics because they are not very profitable.

b) bacterial resistance to the effects of antibiotics is on the rise due to overuse in agriculture and over prescribing by doctors, in addition to other reasons.

c) some bacteria choose to have a mutation that make them resistant to the effects of antibiotics.

d) some bacteria random mutations occur that make them resistant to the effects of antibiotics.

The correct answer is A) pharmaceutical companies generally do not  allocate a lot of money to research for new antibiotics because they are not very profitable.

Explanation:

Bacterial resistance to antibiotics can occur due to various reasons

1 Bacterial resistance to antibiotics is generated due to overuse in agriculture and over prescribing by doctors in addition to other reasons.As a result the bacteria becomes adapted to those antibiotics.

2 Some bacteria choose to have a mutation that makes them resistant to effects of antibiotics.

3 In some bacteria random mutation occurs that make them resistant to the effect of antibiotics.

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.
