A nurse is preparing to administer metronidazole 2g orally to a client diagnosed with trichomoniasis. The available medication 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.)
6 tablets
7 tablets
8 tablets
9 tablets .
The Correct Answer is C
Step 1 is to calculate the number of tablets to administer. The prescription is for 2g of metronidazole and each tablet contains 250mg. To convert grams to milligrams, we multiply by 1000, so 2g is 2000mg. We then divide the total milligrams needed by the milligrams per tablet: (2000mg ÷ 250mg/tablet) = 8 tablets.

Correct Answer is B
Explanation
Choice A rationale
While it’s important to monitor blood pressure in a client with peripartum cardiomyopathy, assessing it twice daily is not a specific intervention for this condition.
Choice B rationale
Restricting daily oral fluid intake is a key intervention in managing peripartum cardiomyopathy. This condition can lead to fluid overload, so limiting fluid intake can help prevent worsening of symptoms.
Choice C rationale
Misoprostol is a medication used to prevent stomach ulcers or to induce labor. It is not used in the management of peripartum cardiomyopathy.
Choice D rationale
Administering an IV bolus of lactated Ringer’s can increase the client’s fluid volume, which is not recommended in peripartum cardiomyopathy as it can exacerbate heart failure symptoms. Explore
Correct Answer is D
Explanation
Choice A rationale
