Question

A patient requires 0.100 g of a drug. the pharmacist has tablets that contain 50.0 mg of the drug. choose the conversion factor that the pharmacist needs to calculate the number of tablets required for the prescribed dosage

Answer 1

To find the number of tablets for a 0.100 g dose when each tablet contains 50.0 mg, convert the prescribed mass to milligrams and divide by the tablet's milligram content, resulting in two tablets.

Step-by-step explanation:

The student's question involves calculating the number of tablets required for a prescribed drug dosage using unit conversion. When a patient requires 0.100 g of a drug and the tablets available contain 50.0 mg of the drug, we need a conversion factor to determine the number of tablets. Since 1 g equals 1000 mg, the conversion factor is 1 g / 1000 mg. Applying this to the prescribed dosage, we find that 0.100 g is equivalent to 100 mg. Therefore, dividing the required dose in milligrams by the milligram content of each tablet gives us the number of tablets needed: 100 mg / 50 mg per tablet equals 2 tablets. This process highlights the importance of unit conversion in medical dosages to avoid errors and ensure patient safety.

Answer 2

The frequency at which the drug doses are administered is known as the dosage regimen. The dosage form refers to the physical form of a dose of the drug. The general dosage forms comprise capsules, tablets, ointments, patches, and aerosols.

The passage of administration refers to the manner in which the drug is administered. The general routes of administration include inhalation, oral, topical, and nasal.

In the given case, the patient needs 0.100 gm of a drug. The tablet is having 50 mg of the drug. Thus, the number of tablets needed for the prescribed dosage is:

0.100 gm * (1000 mg/1 gm) * (1 tablet/ 50 mg) = 2 tablets.
