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 C
Explanation
Choice A rationale
While initiating an infusion of IV fluids for the patient is important, it is not the immediate next step after noticing a protruding umbilical cord.
Choice B rationale
Administering oxygen via a nonrebreather mask at 8L/min is a later step in the management of umbilical cord prolapse.
Choice C rationale
The immediate next step after noticing a protruding umbilical cord is to perform a vaginal examination and apply upward pressure on the presenting part to relieve cord compression.
Choice D rationale
Covering the umbilical cord with a sterile saline-saturated towel is a later step in the management of umbilical cord prolapse.
Correct Answer is A
Explanation
The correct answer is choice a. Check the client’s serum medication level.
Choice A rationale:
Checking the client’s serum medication level is the most direct and objective method to evaluate medication adherence. It provides a quantifiable measure of the digoxin level in the blood, indicating whether the client is taking the medication as prescribed.
Choice B rationale:
Determining the client’s apical pulse rate is important for monitoring the effects of digoxin, as it can affect heart rate. However, it does not directly measure medication adherence.
Choice C rationale:
Asking the client if they are taking the medication as prescribed relies on self-reporting, which can be inaccurate due to forgetfulness or intentional non-disclosure.
Choice D rationale:
Assessing the client’s kidney function is important for dosing and monitoring potential side effects of digoxin, but it does not directly evaluate medication adherence.
