a physician orders aminophylline 7.5 mg per kg of body weight. the patient weighs 110 lb. if aminophylline is available in 0.125

Harman [31]

Answer:

The patient will receive 2 whole tablets.

Step-by-step explanation:

The total weight of the drug to be administered can be expressed as;

Total dose of aminophylline to be administered=Dose per weight of patient×weight of patient

where;

Dose per weight of patient=7.5 mg per kg

weight of patient=110 lb

1 kilogram=2.205 lb

weight of patient in kilograms=110/2.205=49.89 kilograms

replacing;

Total dose of aminophylline to be administered=Dose per weight of patient×weight of patient

Total dose of aminophylline to be administered=(7.5×49.89)=374.175 mg

Total weight of tablets=374.175 mg

Total weight of tablets=weight per tablet×number of tablets

where;

Total weight of tablets=374.175 mg

Weight per tablet=0.125 g

1 gram=1000 mg

Weight per tablet in mg=(1,000×0.125)=125 mg

Number of tablets=n

replacing;

Total weight of tablets=weight per tablet×number of tablets

374.175=125×n

n=374.175/125

n=2.9934

The patient will receive 2 whole tablets.

To get y you can move the x's to one side, so 120y=500-35x
then you can isolate the y, y= 500/120-35x/120

Domain is the set of all inputs to a function on which the function is defined

Given function is:

$f(x) = 5.3^x$

The given function will not be undefined for any value of x as there is no denominator which will make the function approach infinity

Hence,
