Question

1. the medication comes in 25 mg tablets. how many tablets would the patient need to receive 12.5 mg twice a day (bid)?
2. how many tablets would the patient receive for 1 dose of 12.5 mg?
3. how many tablets would the patient need to be prescribed to meet two weeks’ worth of medication at the ordered dose of 12.5 mg twice daily (bid)?

Explanation:

Question 1

Step1: Find daily dose in mg

Daily dose = \(12.5\space mg \times 2 = 25\space mg\)

Step2: Calculate tablets needed

Tablets = \(\frac{\text{Daily dose (mg)}}{\text{Tablet strength (mg)}}=\frac{25}{25} = 1\)

Step1: Use dosage formula

Tablets = \(\frac{\text{Dose (mg)}}{\text{Tablet strength (mg)}}=\frac{12.5}{25}= 0.5\)

Step1: Find daily tablets (from Q1, daily is 1 tablet)

Step2: Calculate total days in 2 weeks

Days = \(2\times7 = 14\) days

Step3: Total tablets = Daily tablets \(\times\) Days

Total tablets = \(1\times14 = 14\)

Answer:

1 tablet
