A nurse is assisting with the care of a client who received magnesium sulfate to treat preterm labor. The nurse should monitor the client for which of the following findings as an indication of magnesium sulfate toxicity?
Nausea.
Facial flushing.
Urine output 40 mL/hr.
Respiratory rate 10/min.
The Correct Answer is D
Choice A rationale
Nausea can be a side effect of magnesium sulfate, but it is not a specific indication of toxicity. Other symptoms are more directly indicative of magnesium sulfate overdose.
Choice B rationale
Facial flushing is a common side effect of magnesium sulfate but is not a sign of toxicity. It typically occurs at therapeutic levels and is not a reliable indicator of overdose.
Choice C rationale
Urine output of 40 mL/hr is within normal limits for an adult and does not indicate magnesium sulfate toxicity. However, significantly decreased urine output could be concerning.
Choice D rationale
Respiratory rate of 10/min is a critical sign of magnesium sulfate toxicity. Magnesium sulfate can cause respiratory depression, and a rate of 10 breaths per minute or less indicates that the patient may be experiencing toxic effects, necessitating immediate medical intervention.

Correct Answer is C
Explanation
Choice A rationale
Taking an over-the-counter antacid is not recommended for managing nausea during pregnancy without consulting a healthcare provider. Some antacids contain ingredients that may not be safe during pregnancy.
Choice B rationale
Increasing intake of fresh fruits might help with hydration and nutrition but is not specifically effective in managing morning nausea. Some fruits might even exacerbate nausea due to their acidity.
Choice C rationale
Eating dry, bland foods in the morning can help manage nausea for pregnant clients. Foods like crackers, toast, and cereals are easy on the stomach and can help reduce morning sickness.
Choice D rationale
Restricting fluids to 1,000 mL/day is not advisable. Proper hydration is crucial during pregnancy, and such restriction can lead to dehydration and other complications. Fluids should be encouraged rather than restricted.
Correct Answer is B
Explanation
Choice A rationale
Ensuring the client has a full bladder before the procedure is incorrect. A full bladder can cause discomfort during the pelvic examination and may obscure the pelvic organs, making the examination more challenging for the provider.
Choice B rationale
Instructing the client to bear down when the speculum is inserted is correct. Bearing down helps relax the pelvic muscles, making it easier to insert the speculum and perform the examination with minimal discomfort.
Choice C rationale
Encouraging the client to take rapid, shallow breaths during the procedure is incorrect. This can increase anxiety and tension in the pelvic muscles, making the examination more uncomfortable.
Choice D rationale
Applying povidone-iodine to the provider's fingers prior to bimanual examination is incorrect. The standard procedure involves using gloves and lubricant to prevent infection and ensure patient comfort, not povidone-iodine.
