Answer:
7.5 tablets
Step-by-step explanation:
It's a units conversion problem. Multiply by the units you want, and divide by the units you don't want. Each conversion factor should be chosen to be "1" so that only the units are changed.
(149 lb)×(0.45359237 kg/lb)×(5 mg/kg)×(1 tab/(45 mg))
= (149×0.45359237×5)/45 tabs
= 7.509 tabs
The nurse will administer 7.5 tablets per day.
