A nurse is discussing fibromyalgia with a client who is concerned about developing the disorder. Which finding would the nurse identify as a risk factor for this disease?

Choice A reason:
Magnesium sulfate is used in the management of severe preeclampsia primarily for seizure prophylaxis. One of the key side effects of magnesium sulfate is its impact on neuromuscular transmission, leading to diminished deep-tendon reflexes as serum magnesium levels rise. The therapeutic range for anticonvulsant prophylaxis is typically between 5-8 mg/dL. Reflexes may begin to diminish when serum levels reach 8-12 mg/dL, indicating potential magnesium toxicity. Therefore, diminished reflexes are a warning sign to reassess the infusion rate and possibly reduce or discontinue the medication.

Choice B reason:
A respiratory rate of 16 breaths per minute falls within the normal adult range and suggests that the client's respiratory system is not being adversely affected by the magnesium sulfate infusion. Respiratory rate is a critical parameter to monitor during magnesium sulfate therapy, as respiratory depression is a serious side effect of magnesium toxicity. Maintaining a normal respiratory rate indicates that it is safe to continue the infusion at the current rate.

Choice C reason:
While a urine output of 50 mL/hr is on the lower end of the normal range, it is still considered adequate for most adults. In the setting of magnesium sulfate therapy for severe preeclampsia, maintaining adequate urine output is essential for ensuring that the kidneys can excrete the magnesium to prevent accumulation and toxicity. If urine output decreases significantly, it may necessitate reevaluation of the infusion rate or additional interventions to support renal function.

Choice D reason:
A heart rate of 56 beats per minute is slightly bradycardic but may not be clinically significant if the client is asymptomatic. However, magnesium has a direct effect on cardiac function, and high levels can lead to bradycardia and other cardiac conduction abnormalities. It is important to monitor the client's heart rate and rhythm during magnesium sulfate therapy to detect any early signs of cardiac involvement due to magnesium toxicity.

Choice A Reason:
Avoiding frustration by performing activities of daily living (ADLs) for the client may seem helpful, but it can actually lead to increased dependency and a faster decline in the ability to perform these tasks. It is important to encourage independence as much as possible.

Choice B Reason:
Telling jokes or riddles and discussing new items might provide temporary entertainment but does not necessarily help a client with dementia function better in their environment. It could also potentially cause confusion or frustration if the client does not understand or remember the context.

Choice C Reason:
Bringing new topics and options to the client's attention can be overwhelming and may contribute to confusion. Clients with dementia benefit from consistency and routine, which helps them feel more secure and oriented.

Choice D Reason:
Assisting the client to perform simple tasks by giving step-by-step directions is a beneficial intervention. It supports the client's ability to maintain independence and function within their environment for as long as possible. This approach aligns with the goal of maximizing the client's abilities and fostering a sense of accomplishment.
