Answer 1

12. Three

Required dosage of phenytoin is 0.3 g. Which is = 300 mg ( cause 1g = 1000mg )

Available capsules are 100mg. This is 1/3rd of required dosage per capsule.

So in order to get the required dosage, we should give three capsules.

13. Two tablets q(every) 6hr.

Required dosage of dexamethasone is 4mg PO q 6hr.

Available 2 mg/tab. This is half of required dosage.

So to get required dosage of 4 mg, the nurse should administer two tablets PO q 6hr.

14. Two tablets

Required dosage of digoxin is 0.25 mg.

Availabe dosage is 0.125 mg/ tab. This is half of the required dosage per tab.

So to get the required dosage, the nurse should administer two tablets.
