Answer:
1/2 tablet, or half of one tablet
Step-by-step explanation:
In order to solve for the dosage amount of medication for the nurse to administer to the patient, the ordered amount must be multiplied by the dosage strength. This formula is:
dosage amount = ordered amount x dosage strength
The ordered amount, as it may sound, is the quantity of medication prescribed by the provider, which in this case is the physician. The ordered amount is 0.3 milligrams (0.3 mg).
The dosage strength is what medication is available to be administered, usually provided by the pharmacy. It is typically presented as a form of fraction know as a conversion factor. Though it may not be as apparent, there is one present in the given statement. 0.6 mg tablets available means there is 0.6 mg per tablet, which is represented by the fractions (0.6 mg / tablet) and (tablet / 0.6 mg).
The dosage amount is then the amount to be administered to the patient following the completion of calculation. To solve, plug in the above information into the formula.
0.3 mg x tablet / 0.6 mg
0.3 mg tablet / 0.6 mg
Milligrams in both numerator (top) and denominator (bottom) cancel each other, leaving tablets as the sole unit of measurement.
0.3 tablet / 0.6
0.3 ÷ 0.6 = 1/2
= 1 / 2 tablet
Therefore, the nurse should administer 1/2 tablet of medication.
