The Correct Answer is B
The nurse should administer 2 tablets.
Since each tablet contains 1.5 mg of dexamethasone, to administer a dose of 3 mg, the nurse should give 3 mg / 1.5 mg/tablet = 2 tablets.
Choice A is incorrect because 1 tablet would only provide a dose of 1.5 mg.
Choice C is incorrect because 3 tablets would provide a dose of 4.5 mg.
Choice D is incorrect because 4 tablets would provide a dose of 6 mg.
