The pharmacy supplies levothyroxine as scored tablets containing 50 mcg50\text{ mcg} per tablet. How many tablets should the nurse administer?

Record answer to the nearest tenth. Do not include units in answer.

Cevap: 2.5 tablets

Cevap

2.5
To safely administer the correct dose, the practical nurse must ensure the prescribed dose and the supplied dose are in the same unit of measurement. Converting the prescribed 0.125 mg0.125\text{ mg} to micrograms yields 125 mcg125\text{ mcg}. Dividing the desired dose (125 mcg125\text{ mcg}) by the available dose (50 mcg50\text{ mcg} per tablet) results in 2.5 tablets2.5\text{ tablets}. Because the tablets are scored, it is safe and appropriate to administer two and a half tablets to achieve the prescribed dose.

Adım Adım Çözüm

1
Convert the prescribed dose of levothyroxine from milligrams (mg) to micrograms (mcg) by multiplying by 1000.
0.125 mg×1000=125 mcg0.125\text{ mg} \times 1000 = 125\text{ mcg}
The prescribed dose and the supplied medication must be in the same unit of measurement before calculating the physical dosage.
2
Use the standard dosage calculation formula: Desired DoseAvailable Dose×Quantity\frac{\text{Desired Dose}}{\text{Available Dose}} \times \text{Quantity}.
125 mcg50 mcg×1 tablet=2.5 tablets\frac{125\text{ mcg}}{50\text{ mcg}} \times 1\text{ tablet} = 2.5\text{ tablets}
This calculation determines the exact physical quantity of the medication to administer based on the available pharmacy supply.
