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.

Explanation
Choice A rationale
Contractions feeling further apart is not a direct indicator of the effectiveness of the hands-and-knees position in relieving discomfort associated with a fetus in the occipitoposterior position.
Choice B rationale
Feeling relief from pelvic pressure may not directly indicate the effectiveness of the hands-and-knees position in relieving discomfort associated with a fetus in the occipitoposterior position.
Choice C rationale
Improvement in back labor is a direct indicator of the effectiveness of the hands-and-knees position in relieving discomfort associated with a fetus in the occipitoposterior position.
Choice D rationale
Lessening of suprapubic pain may not directly indicate the effectiveness of the hands-and-knees position in relieving discomfort associated with a fetus in the occipitoposterior position.
Correct Answer is D
Explanation
Choice A rationale
Amniocentesis is not a surgical procedure that requires general anesthesia, so the client will not be asleep during the procedure.
Choice B rationale
Fasting is not typically required before an amniocentesis. The procedure involves inserting a thin needle into the amniotic sac to withdraw a small amount of fluid for testing. It does not involve the digestive system, so there is no need for the client to fast.
Choice C rationale
While the client may be in various positions during the procedure, lying on the side is not typically required. The position of the client during the procedure is determined by the location of the baby and the amniotic sac.
Choice D rationale
Emptying the bladder before the procedure can make it easier for the healthcare provider to access the uterus and amniotic sac. Therefore, this statement indicates an understanding of the teaching.
