Answer:
The patient will receive 2 whole tablets.
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.
