A nurse is caring for a pregnant client with severe preeclampsia who is receiving IV magnesium sulfate.
Select all nursing interventions that apply in the care for the client.
Monitor deep tendon reflexes hourly.
Notify the physician if urinary output is less than 30 ml per hour.
Keep calcium gluconate on hand in case of a magnesium sulfate overdose.
Monitor maternal vital signs every 6 hours.
Monitor intake and output hourly.
Monitor renal function and cardiac function closely.
Correct Answer : A,B,C,E,F
Choice A rationale
Hourly monitoring of deep tendon reflexes is crucial in clients receiving magnesium sulfate for severe preeclampsia. Magnesium sulfate acts as a central nervous system depressant, and diminished or absent deep tendon reflexes (normal range: 2+ to 4+) can indicate magnesium toxicity, necessitating immediate intervention to prevent serious complications like respiratory depression.
Choice B rationale
A urinary output of less than 30 mL per hour signals potential renal hypoperfusion, which can be exacerbated by severe preeclampsia and magnesium sulfate administration. Reduced kidney function can lead to the accumulation of magnesium, increasing the risk of toxicity. Prompt notification of the physician allows for timely adjustments in the treatment plan.
Choice C rationale
Calcium gluconate is the antidote for magnesium sulfate overdose. Having it readily available is essential in case the client exhibits signs of magnesium toxicity, such as respiratory depression, severe hypotension, or loss of reflexes. Prompt administration of calcium gluconate can reverse the effects of magnesium and prevent life-threatening complications.
Choice E rationale
Hourly monitoring of intake and output is vital to assess fluid balance and renal function in pregnant clients with severe preeclampsia receiving magnesium sulfate. Accurate measurement helps in detecting oliguria, a sign of worsening preeclampsia or magnesium toxicity, allowing for timely interventions to maintain adequate hydration and prevent complications.
Choice F rationale
Severe preeclampsia significantly impacts both renal and cardiac function due to widespread vasoconstriction and endothelial dysfunction. Close monitoring of these systems through laboratory tests (e.g., serum creatinine, BUN, electrolytes, ECG) and clinical assessments is essential to detect and manage potential complications such as acute kidney injury, heart failure, and arrhythmias.

Correct Answer is []
Explanation
Rationale for Correct Condition
Subinvolution refers to delayed uterine involution, often due to retained placental fragments or infection. The boggy uterus, excessive lochia, and passage of clots are hallmark signs. The history of postpartum hemorrhage increases risk, and fundal tenderness suggests uterine atony rather than infection or hematoma formation.
Rationale for Correct Actions
Oxytocin enhances uterine contractions to reduce bleeding and facilitate involution by increasing myometrial tone. Methylergonovine is a potent uterotonic that further supports contraction, decreasing hemorrhage risk, but must be used cautiously in hypertensive patients.
Rationale for Correct Parameters
Saturated perineal pads track blood loss severity, guiding interventions for ongoing hemorrhage. Excessive bleeding may require further medical management. Hemoglobin and hematocrit assess for anemia due to blood loss, guiding transfusion decisions if needed.
Rationale for Incorrect Conditions
Postpartum preeclampsia presents with hypertension and proteinuria, not uterine atony. Perineal hematoma manifests as localized swelling with severe perineal pain, which is absent here. Thrombophlebitis involves unilateral extremity swelling and pain, not fundal tenderness or abnormal lochia.
Rationale for Incorrect Actions
Ice packs to the perineum manage hematomas, not uterine atony. Anticoagulants are used for thromboembolic prevention, not postpartum bleeding. Quiet environment is relevant for preeclampsia, not uterine subinvolution.
Rationale for Incorrect Parameters
Seizures are relevant to preeclampsia, not uterine subinvolution. Calf circumference is monitored for thrombophlebitis, which is absent here. Rectal pain is not an expected indicator of uterine involution status.
Correct Answer is B
Explanation
Choice A rationale
A glucose reading of 58 mg/dL in a newborn is below the normal range (typically 40-60 mg/dL in the first hours of life, rising to 50-90 mg/dL). While this requires intervention to prevent hypoglycemia, other parameters might indicate a more immediate threat to the newborn's well-being.
Choice B rationale
A temperature of 97.4°F (36.3°C) is below the normal range for a newborn (typically 97.7°F to 99.5°F or 36.5°C to 37.5°C). Hypothermia in a newborn can lead to cold stress, increasing oxygen and glucose consumption, potentially leading to respiratory distress and hypoglycemia. Therefore, a low temperature requires immediate assessment and intervention to warm the newborn.
Choice C rationale
A respiratory rate of 48 breaths/minute is within the normal range for a newborn (typically 30-60 breaths/minute). While the respiratory rate should be monitored, it does not indicate an immediate critical issue in this case.
Choice D rationale
A pulse of 134 beats/minute is within the normal range for a newborn (typically 110-160 beats/minute). While the heart rate should be monitored, it does not indicate an immediate critical issue in this case. .
