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.

Correct Answer is A
Explanation
Choice A rationale
If a nurse notes a steady trickle of vaginal bleeding that does not stop with fundal massage after a cesarean birth, administering a 500 mL lactated Ringer’s IV bolus can help increase the client’s circulating volume and support her hemodynamic stability. This is often the first step in managing postpartum hemorrhage.
Choice B rationale
While evaluating urinary output is an important aspect of postoperative care, it would not directly address the issue of ongoing vaginal bleeding.
Choice C rationale
Applying an ice pack to the incision site can help reduce swelling and provide some pain relief, but it would not address the issue of vaginal bleeding.
Choice D rationale
Replacing the surgical dressing is part of routine postoperative care, but it would not directly address the issue of ongoing vaginal bleeding.
Correct Answer is D
Explanation
The correct answer is choice d. Administering broad-spectrum antibiotics.
Choice A rationale:
Cleansing the site with povidone-iodine is not recommended because it can be irritating and potentially harmful to the exposed neural tissue.
Choice B rationale:
Monitoring the rectal temperature every 4 hours is not appropriate as it can increase the risk of infection and trauma to the site. Axillary temperature monitoring is preferred.
Choice C rationale:
Preparing for surgical closure after 72 hours is incorrect. Surgical closure is typically performed within the first 24 to 48 hours to prevent infection and further damage to the neural tissue.
Choice D rationale:
Administering broad-spectrum antibiotics is crucial to prevent infection, especially since the cerebrospinal fluid is leaking, which increases the risk of meningitis and other infections.
