Question

a patient is prescribed lasix 80 mg by mouth twice a day. how many tablets are needed for the entire day if the medication available is 40 mg/tablet? 1 tablet 2 tablets 3 tablets 4 tablets

Explanation:

Step1: Calculate total daily dosage

The patient takes 80 mg twice a day, so total daily dosage is \( 80 \, \text{mg} \times 2 = 160 \, \text{mg} \).

Step2: Calculate number of tablets

Each tablet is 40 mg, so number of tablets is \( \frac{160 \, \text{mg}}{40 \, \text{mg/tablet}} = 4 \).

Answer:

4 tablets (corresponding to the option: 4 tablets)
