A nurse is observing a new mother bathing her newborn son for the first time. For which of the following actions should the nurse intervene?

Choice A reason:
Continuous fetal monitoring is a standard order for clients with severe preeclampsia. It allows healthcare providers to assess the baby's heart rate pattern, which can indicate how well the baby is tolerating the intrauterine environment. This is particularly important in cases of severe preeclampsia, where there is a risk of fetal distress.

Choice B reason:
Obtaining a daily weight is also a standard practice for clients with severe preeclampsia. Weight gain can be an indicator of worsening preeclampsia due to fluid retention and should be monitored closely. Sudden weight gain can signify increased fluid retention, which may require medical intervention.

Choice C reason:
Assessing deep tendon reflexes every hour is appropriate for clients with severe preeclampsia. Hyperreflexia can be a sign of worsening preeclampsia and impending eclampsia. Frequent monitoring allows for early detection of changes in reflexes, which can be critical in managing the condition.

Choice D reason:
Ambulating twice daily would require clarification because clients with severe preeclampsia are typically advised to have bed rest to lower blood pressure and reduce the risk of complications. Ambulation could increase the risk of hypertensive crisis or other complications, so this order seems contrary to standard management practices for severe preeclampsia.

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.
