Final answer:
To administer the prescribed 0.250 mg of medication with 0.125 mg tablets on hand, the patient should be given 2 tablets.
Step-by-step explanation:
The question involves calculating the number of tablets a patient needs to take to meet the dosage prescribed by a physician. The physician has ordered a dosage of 0.250 mg of a medication, whereas the tablets available are in 0.125 mg strength.
To find out how many tablets are needed for a 0.250 mg dosage, one can simply divide the ordered dosage by the strength of the tablets on hand:
- Dosage ordered: 0.250 mg
- Strength of tablets: 0.125 mg per tablet
The number of tablets required is calculated as:
Number of tablets = (Dosage ordered) / (Strength of one tablet)
Number of tablets = 0.250 mg / 0.125 mg per tablet
Number of tablets = 2
Therefore, to achieve the ordered dose of 0.250 mg, the patient should be given 2 tablets of the medication.
