A nurse is preparing to administer metronidazole 2 g PO to a client who has trichomoniasis. Available is metronidazole 250 mg tablets.
How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies.
Do not use a trailing zero.) .
The Correct Answer is ["8"]
Step 1 is to determine the total amount of metronidazole needed, which is 2 g.
Step 2 is to convert grams to milligrams, as the available medication is in milligrams. So, 2 g is equal to 2000 mg.
Step 3 is to calculate the number of tablets needed. Each tablet contains 250 mg of metronidazole. Therefore, the calculation is 2000 mg ÷ 250 mg/tablet.
