A nurse is preparing to administer famotidine 40 mg PO at bedtime. Available is
famotidine 20 mg/tablet. How many tablets should the nurse administer?
(Round answer to nearest whole number. Use a leading zero if it applies. Do not use a
trailing zero.) - CORRECT ANSWERS -Answer: 2 tablets
Follow these steps for the Ratio and Proportion method of calculation:
Step 1: What is the unit of measurement the nurse should calculate? tablet(s)
Step 2: What is the dose the nurse should administer? Dose to administer = Desired 40
mg
Step 3: What is the dose available? Dose available = Have 20 mg
Step 4: Should the nurse convert the units of measurement? No
Step 5: What is the quantity of the dose available? 1 tablet
Step 6: Set up an equation and solve for X.
Have/Quantity = Desired/X
20 mg/ 1 tablet = 40 mg/X tablet(s)
X tablet(s) = 2 tablets
Step 7: Round if necessary.
Step 8: Determine whether the amount to administer makes sense. If there are 20
mg/tablet and the prescription reads 40 mg, it makes sense to administer 2 tablets. The
nurse should administer famotidine 2 tablets PO at bedtime.
